Definitions
- the present invention relates to a wristwatch, in particular an electronic wristwatch having a high-resolution display screen.
- Wristwatches can be classified into two main families depending on the type of movement used.
- Electronic watches most often regulated by a quartz, have the advantage of high precision and moderate cost thanks to industrial manufacturing techniques.
- the time calculated by electronic watches is most often displayed digitally on a liquid crystal segment display, or sometimes by means of hands driven by a step-by-step motor whose operation is regulated by the quartz.
- Liquid crystal segment displays have the disadvantage of limited contrast making reading the digital symbols formed by the segments uncomfortable, especially in low ambient light. Stepper motors generally cause the needles to move jerkily, judged not to be very quiet and not very representative of the continuous flow of time.
- GB2425370 describes a table clock comprising a video screen for displaying a looped film with representations of humans. This solution is not suitable for a wristwatch.
- US20050278757 describes a system for downloading watch faces displayed on a device.
- US20030214885 describes a watch whose dial is replaced by a screen allowing the time to be represented in different ways. None of these solutions of the prior art makes it possible to display the movement of the watch. These solutions do not offer the curiosity of beautiful mechanical watches, and are intended for lovers of electronic watches.
- WO2011000893 which comes under Art 54 (3) EPC, discloses a wristwatch comprising a microcontroller arranged to reproduce on an electronic display the simulation of a mechanical watch movement.
- An object of the present invention is to provide a wristwatch combining the advantages of watches with mechanical movements and those of electronic watches.
- independent claim 13 defines a corresponding method of displaying information in an electronic watch.
- dependent claims 14 and 15 define particular embodiments of this process.
- This watch thus makes it possible to display a simulated mechanical movement as complex as desired while avoiding the costs of manufacturing a real, physical and tangible mechanical movement.
- the precision of this watch can be as high as that of an electronic watch while offering the animations of a higher category mechanical watch.
- the invention starts in particular from the observation that modern electronic displays allow sufficient realism to display a credible simulation of a complex mechanical movement; the necessary resolution would have been impossible to obtain a few years ago, or would have required power consumption incompatible with integration into a wristwatch.
- the invention also starts from the observation that the computing power of current watchmaking microcontrollers (that is to say microcontrollers of size and consumption compatible with a watchmaking application) makes it possible to calculate and display in real time a realistic simulation. of a complex mechanical movement.
- the simulated mechanical movement is advantageously displayed over the entire surface of the electronic display, which is mounted edge to edge against the internal face of the flange or the bezel. In this way, the simulated mechanical movement occupies the position and dimensions of an actual mechanical movement. Indicating members, for example needles, discs, cylinders etc. can be displayed on the display. Control means make it possible to modify the display and to select a mechanical movement from among several available movements. It is also possible to display a simulated dial, or a real dial, totally or partially covering the simulated mechanical movement.
- the display is a display associated with a touch sensor, for example a display associated with a multi-touch or single-touch touch sensor.
- a touch sensor for example a display associated with a multi-touch or single-touch touch sensor.
- This increases the realism of the representation; the user can for example influence the position or displacement of a component of the movement by pressing or moving the representation of this component.
- the watch comprises a crown outside the case and a representation of the virtual and simulated crown stem displayed on the screen opposite this crown.
- the position of the crown stem is modified by the microcontroller of the watch when this microcontroller detects an actuation of the crown, so as to simulate a direct action of the crown on the simulated crown stem.
- This crown can also be used for setting the time or for winding the simulated mechanical movement; this movement can for example stop after some time if it is not wound up by the physical crown.
- the action of the physical push buttons on the movement can be simulated by displaying a simulated organ next to the push button, the position of which is modified when the push button is actuated, so as to simulate a direct action. on said member simulated by said push-button.
- the wristwatch further comprises an accelerometer used for example to increase the realism of the representation, by making it dependent on the accelerations undergone by the watch.
- the position of at least one element of the movement depends on an output signal from the accelerometer. It is so possible to simulate the displacement of an oscillating weight for winding the simulated movement according to the watch, to visualize the deformations of the hairspring or the displacements of a tourbillon or of the balance according to gravity, or to show the oscillations of the train gear or other components when the watch is shaken.
- the microcontroller calculates the forces and the displacement undergone by these elements as a function of the measured acceleration, for example gravity or a shock, and displays these displacements or deformations.
- At least some elements, for example the springs or the hairspring also have virtual rigidity and deform as a function of the measured accelerations or the displacements of other components of the simulated movement.
- the acceleration can for example be measured along 3 axes. It is also possible to measure rotations along one or more axes with a gyroscope.
- the rate of movement depends on the measured accelerations. For example, it is possible to take into account the effect of gravity and of shocks on the regulating member in order to affect the rate of this regulating member or the position of a tourbillon.
- a simulated barrel can discharge if the accelerometer does not detect any acceleration to move the oscillating mass, and mechanical motion can slow down and then stop if discharged.
- the time displayed by the displayed movement therefore preferably depends on the results of the simulation, taking into account the rigidity of the parts or the measured accelerations.
- the time of the simulated movement is synchronized with the time determined by the quartz movement, in order to reset the simulated mechanical movement. This synchronization can be performed automatically, for example periodically or in the event of a variation. exceeding a predetermined threshold, and / or at the request of the user by an appropriate command.
- One advantage of the present solution is that it makes it possible to simulate and display mechanical movements which would be impossible or very expensive to manufacture in practice. For example, it is possible to display virtual mechanical movements, simulated with a regulating organ oscillating at a much higher frequency than in a classical movement, and with organs which rotate much faster, producing a more interesting animation.
- oscillating masses or balances are simulated with a very high density, and other moving parts with a density that is on the contrary lower than that permitted by ordinary materials.
- barrel or hairspring springs can be simulated with much greater return stresses than in the prior art.
- the simulation is however always a “realistic” simulation, calculated taking into account correct physical laws even if it is based on properties of non-existent materials.
- the display does not reproduce a simple animated image or a video previously recorded and displayed in a loop, but a calculated simulation of the position of the elements displayed taking into account for example the shape and the simulated mass. of these elements and of the environment (for example buttons, acceleration, etc.). Each successive image is therefore calculated in real time by the microcontroller and generated dynamically taking into account external parameters. This increases the realism.
- the display is preferably a display associated with a two-dimensional touch sensor making it possible to detect the movements of at least one finger in at least two different directions
- the watch comprising a processing circuit specifically designed to interpret signals from the touch sensor, to select a screen from among several screens available as a function of these signals, and to display this screen over the whole of said display.
- the processing circuit is specifically designed so as to cause scrolling of screens in order to permanently replace the map initially displayed by another screen, the direction and the direction of scrolling depending on the direction and direction of said displacement.
- Each screen displayed can be associated with an application determining the animated image displayed.
- the wristwatch also has the advantage of switching from one screen to another very simply, by simple horizontal or vertical movements of the finger on the crystal, taking into account the direction and direction of movement of the finger on the screen.
- Scrolling from one screen to another can for example correspond to a change of watch mode.
- the replacement of a simulated mechanical display is done by scrolling through screens, and by replacing the entire image displayed on the watch with the image of another screen.
- the figure 1 schematically illustrates various components of a simulated mechanical watch 1 according to the invention.
- a simulated mechanical watch 1 comprises a housing 5 housing a microcontroller 10 displaying indications on a high-resolution digital display 4 which occupies almost the entire surface under the glass, and thus serves both as a watch face and as a time indicator.
- the display consists of a color liquid crystal matrix display (LCD or TFT) with at least 150 ⁇ 150 pixels.
- LCD or TFT color liquid crystal matrix display
- Other types of displays including displays based on OLED technology for example, can be employed.
- the watch could also include several displays, for example several digital displays, or a digital matrix display combined with hands or other mechanical indicators.
- the microcontroller makes it possible to execute different applications in order on the one hand to determine the current time and other chronological indications as a function of the output signals of a quartz oscillator 11 in the housing, or of another reference signal. temporal.
- the microcontroller runs computer applications stored in a semi-permanent memory in order to control the indications displayed on the display 4 according to the time indications and the commands of the user or of various sensors.
- the applications executed by the microcontroller can be updated for example through a wireless interface not shown, or a micro-USB type connector for example, in order to load other portions of codes making it possible to display other indications or the same indications in a different way.
- the watch can also include several microcontrollers, for example a microcontroller to control the matrix display, another microcontroller to control the touch interface, and a general microcontroller to determine the indications to be displayed at each moment, according to the selected card. These different microcontrollers can also be grouped together differently.
- the display 4 is preferably a display associated with a touch sensor, for example a display associated with a single touch or multitouch touch sensor.
- multi-touch sensor is meant in the present application a touch sensor capable of detecting several simultaneous contact points, for example the simultaneous movements of several fingers on the touch surface. It is surprising to use a multitouch screen on the small surface of a wristwatch, despite all expectations this technology is however effective in entering complex commands more quickly than with a single touch screen.
- the electrodes of this equipment are preferably associated with a circuit or with software which interprets these simultaneous contacts and which converts them into commands executed by the microcontroller 10.
- the watch is characterized by displaying a single icon or card at a time, with each card filling the entire screen.
- the different cards are arranged on a single plane and the choice of a screen is made only by horizontal or vertical movements, in the same plane, without ever switch to a different plan. The risk of losing the user in navigating between several planes of icons or superimposed maps is thus avoided.
- the course of the programs executed by the microcontroller 10 can also be modified by acting on monostable pushbuttons 41 and / or on the axial and / or angular position of a crown 42 (optional).
- Reference numeral 43 denotes additional light indicators, for example light diodes on the outer surface of the case 5 or the bracelet.
- the user interface can also include a loudspeaker (not shown) to reproduce sounds generated or stored by the microcontroller, a wireless interface (not shown) of the ZigBee or Bluetooth type for example, a microphone, etc.
- the watch can also include a speaker which can be used to reproduce sounds.
- the sounds generated and reproduced depend on the simulation displayed, for example in order to reproduce a “tick tock” synchronized with the oscillations of the simulated regulating organ.
- the power supply of the watch is advantageously done by means of a rechargeable battery through a micro- or nano-USB connector, a specific or proprietary connector or, in a variant, through a radiofrequency interface. .
- the wristwatch of the invention also advantageously comprises an accelerometer 12 capable of measuring the acceleration undergone by the watch and of supplying a signal to the microcontroller 10 depending on this acceleration.
- the accelerometer is preferably a 3D accelerometer capable of measuring acceleration in three dimensions, and of determining the vertical direction during periods of immobility. This acceleration is for example useful for controlling and rotating the display according to the orientation of the watch, and for simulating the effect of the acceleration on the parts shown on the screen, in particular the deformation of the hairspring, as in will see it below. It is also possible to use an accelerometer combined with a gyroscope to measure angular acceleration along one or more axes, and to simulate the effect of rotations on the displayed representation.
- the figures 2 to 5 illustrate various display examples on a wristwatch 1 according to the invention.
- the illustrated watch comprises in particular a bracelet 2 and a case 5 provided with a crystal 3 covering a digital matrix display 4. It integrates for example the circuit of the figure 1 .
- the box 5 may include control members, for example push-buttons 41, a crown 42, etc., which are however not essential for handling; on the figures 2 , 3 and 5 , the watch has no crown and only has pushbuttons 41 for switching the screen on or off, for adjusting its brightness or for controlling applications. It is also possible, in an option, to produce a watch without a push-button and / or in which the screen is turned on or off via the touch screen, for example by long pressing on a predetermined area of the touch screen. . As an option, a light sensor (not shown) automatically adapts the intensity of the screen to the ambient light. This sensor can also be used to adapt the intensity and direction of shadows simulated and drawn on the display according to the intensity and direction of the ambient light.
- control members for example push-buttons 41, a crown 42, etc.
- the crystal 3 closes the upper surface of the case and covers the digital matrix display 4. It is preferably made of sapphire or another scratch-resistant material, and covered with an antireflection treatment. In a preferred embodiment, the crystal is convex cylindrical, or possibly convex spherical.
- Transparent electrodes are placed in or under the glass 3 in order to detect the presence of a finger or a stylus.
- the detection technology preferably uses methods known in the state of the art, for example capacitive detection.
- the microcontroller 10 makes it possible to interpret the signals coming from the electrodes and to display on the matrix display 4 indications which depend on these signals.
- the user can switch from one display mode to another, and for example replace the display of the figure 2 by that of one of the figures 3, 4 or 5 , or by another display, simply by scrolling through the displays on the screen by moving your finger on the screen in the desired scrolling direction.
- the figure 2 illustrates a display mode in which the time is displayed by means of a simulated virtual mechanical movement and displayed on screen 4.
- the hours, respectively the minutes are displayed by means of simulated jumping cylinders 15 , 16 indexed almost instantaneously at each change of hour or minute.
- the seconds are displayed by means of a simulated linear retrograde seconds hand 17 moving at 6 o'clock at the bottom of the screen.
- the movement illustrated here is of the skeleton type and reveals part of the cogs and other components of the movement. In this example, most of the wheels and pinions are arranged around horizontal axes (parallel to the dial).
- the wristwatch therefore displays the simulated movement and the indicators 15, 16, 17 over the entire surface of the electronic display, so that it occupies the position and dimensions of an actual mechanical movement in a skeleton watch. for example.
- the user thus has the impression of wearing a real mechanical watch.
- the microcontroller 10 can display shadows on the organs of the simulated movement; the intensity and direction of shadows may also depend on ambient light measurements taken by one or more light sensors.
- the user can replace a displayed simulated movement with another available movement.
- the figure 3 illustrates the display of a movement allowing the display of the date, respectively of the day of the week by means of jumping rollers 18 and of a retrograde linear hand 19 respectively.
- These elements can be represented on the same display 4 instead of the indications on the figure 2 , the user being able to switch freely from one representation to another and replace the display of the first movement with that of the second movement.
- the figure 4 illustrates another way of displaying the time by means of hands 20 of the hours and minutes displayed on the screen 4.
- the hands 20 rotate in front of a simulated skeleton movement comprising in particular cogs 30 and other elements not shown, for example a regulating organ, a barrel, an oscillating weight, or other simulated complications.
- the physical crown 42 on the outside of the watch can be manipulated to wind or time this simulated movement.
- a simulated crown rod 420 is displayed on the screen 4 opposite the crown 42; this rod is controlled by the microprocessor so as to follow the manipulations of the physical crown 42, giving the user the impression of actually manipulating this crown rod 420 and the organs which are linked to it.
- the action on the push-buttons 41 outside the housing 5 advantageously has repercussions on the corresponding members 410 displayed on the screen 4, giving the user the impression of manipulating these members.
- the user can also interact with the elements of the simulated movement through the touchscreen 40. For example, in one embodiment, he can move or block the hands 20, or other components, simply by moving or pressing the button. finger on the displayed representation of these components.
- this displacement causes a modification of the rate of the movement. For example, if the user moves a hand with the finger, the displayed time is permanently modified, and the hand starts again from the location where the user left it. Likewise, if a user prevents a wheel or pinion from turning, the simulated movement is stopped for the duration of the lockup, and the watch is thus delayed.
- the user can also temporarily remove components from the movement, for example cogs, bridges etc., by means of the finger; this allows for example to observe parts in the background that would be hidden by others.
- the watch comprises an accelerometer 12 generating an output signal which influences the rate of the simulated movement which is displayed. For example, jerks measured by the accelerometer can impact the gear train which can be shown vibrating in their simulated bearings. If the movement has a simulated oscillating mass (not shown), the oscillations of the watch may cause this displayed oscillating mass to oscillate, which can be used to reload a simulated virtual barrel and wind the watch. Likewise, the influence of gravity and other accelerations on the shape of the virtual hairspring and on the oscillations of the virtual balance can be simulated and displayed, as can the movements of a simulated vortex for example.
- the movement shown is a real simulation of a mechanical movement.
- the simulated components represented therefore have a virtual mass, and simulated torques or forces are transmitted from one component to another, for example through the gear train.
- some components such as springs have virtual rigidity.
- the microcontroller thus calculates and displays at all times a simulation of the position of each component based on interactions with other components, acceleration and user interactions on crown 42, pushbuttons or crystal for example .
- the time displayed at all times therefore results from this simulation, and can for example be disturbed by the accelerations of the simulated regulating organ or by imperfections in the movement. This time can therefore differ from the generally more precise time calculated by the microcontroller 10 on the basis of the indications of the quartz oscillator 11.
- the time displayed by the simulated and displayed mechanical movement is therefore synchronized. with the quartz time, either automatically at regular intervals or when the difference exceeds a threshold, or manually by user interaction on one of the push buttons 41 or on the touch sensor.
- quartz 11 It is also possible, in a variant that is simpler to produce but less realistic, to display a pure image of a movement on the screen, with a position of each component and of the hands which is directly determined from the time. quartz 11. Moreover, the same watch can offer both types of display, for example on two display modes selectable by the user.
- the watch of the invention can also be used to display indications other than simulated mechanical movements.
- the figure 5 illustrates a mode of digital representation of the current time on the screen 4.
- Other indications for example other digital displays or virtual hands, calendars, images, photos, text, multimedia pages, etc. can be displayed on display 4.
- the figure 6 schematically illustrates a possible arrangement of screens which allow different indications or images to be displayed. At least one screen corresponds according to the invention to the display of a simulated mechanical movement. Other screens can be selected to display other mechanical movements, or other indications related or not to the time indication.
- each selectable screen corresponds to the size of display 4.
- the user can modify the current display by permanently replacing, until the next replacement, the screen displayed by any other selected screen. .
- the selectable screens are virtually arranged to form a row 22 and a virtual column 21.
- the user can scroll through the screens in the horizontal direction, in order to replace the current screen 23 with any other. screen 220 to 225 in row 22.
- the user can scroll through the screens vertically in order to choose one of screens 210 to 213 in column 21. All the available information can therefore be displayed by simply scrolling horizontally or vertically .
- the scrolling of the screens in the horizontal or vertical direction is obtained by moving the finger on the glass in the corresponding direction and in the corresponding direction.
- the user can easily consult the available screens, and choose a particular screen with simple movements of the finger in the horizontal or vertical direction.
- the user can add screens, delete screens, modify the order of the screens in the row and the column, etc., from a particular menu of the watch or from a personal computer connected to the watch.
- a user can thus update a mechanical movement, or add an additional representation of a mechanical movement in an existing watch.
- Each screen can be associated with a computer program or module to calculate the displayed data, and with data used by this module, for example in order to calculate and display the position of each of the components of a simulated virtual mechanical movement.
- different screens corresponding to different mechanical movements can be associated with different computer programs making it possible to simulate these movements and display the corresponding simulations.
- each screen may display a different indication or correspond to a particular operating mode of the watch.
- screens 220, 221, and 222 are used to display the current time in the Tokyo, New York, and Los Angeles time zones.
- the screens 210, 211, 212 and 213 make it possible to display the number of days, respectively hours, since a given moment, for example since birth, since marriage, quitting smoking, etc.
- Other maps or screens may be used to display moon phases, a calendar, or other hourly or non-hourly indications.

Description
La présente invention concerne une montre bracelet, en particulier une montre bracelet électronique disposant d'un écran d'affichage à haute résolution.The present invention relates to a wristwatch, in particular an electronic wristwatch having a high-resolution display screen.
Les montres bracelets peuvent être classées en deux familles principales en fonction du type de mouvement utilisé. Les montres électroniques, le plus souvent régulées par un quartz, présentent l'avantage d'une grande précision et d'un coût modéré grâce à des techniques de fabrication industrielles. L'heure calculée par les montres électroniques est les plus souvent affichée de manière numérique sur un affichage à segments de cristaux liquides, ou parfois au moyen d'aiguilles entraînées par un moteur pas-à-pas dont la marche est régulé par le quartz. Les affichages à segments de cristaux liquides présentent l'inconvénient d'un contraste limité rendant la lecture des symboles numériques formés par les segments inconfortable, notamment par faible lumière ambiante. Les moteurs pas-à-pas provoquent généralement un déplacement par à-coups des aiguilles, jugé peu tranquille et peu représentatif de l'écoulement continu du temps.Wristwatches can be classified into two main families depending on the type of movement used. Electronic watches, most often regulated by a quartz, have the advantage of high precision and moderate cost thanks to industrial manufacturing techniques. The time calculated by electronic watches is most often displayed digitally on a liquid crystal segment display, or sometimes by means of hands driven by a step-by-step motor whose operation is regulated by the quartz. Liquid crystal segment displays have the disadvantage of limited contrast making reading the digital symbols formed by the segments uncomfortable, especially in low ambient light. Stepper motors generally cause the needles to move jerkily, judged not to be very quiet and not very representative of the continuous flow of time.
Les mouvements mécaniques permettent d'afficher l'heure au moyen d'aiguilles ou d'autres indicateurs se déplaçant de façon quasi continue tout en permettant une lecture confortable même lorsque la lumière ambiante est faible. Par ailleurs, l'extraordinaire ingéniosité de certains mouvements mécaniques et la possibilité de visualiser leurs composants est jugée fascinante par de nombreux utilisateurs, notamment dans le cas de montres squelettes permettant d'admirer des parties du mouvement, à travers la glace et le cadran. Les montres mécaniques suscitent donc un engouement considérable et il existe un besoin commercial établi pour des montres mécaniques avec un cadran animé par les éléments du mouvement en déplacement.The mechanical movements allow the time to be displayed by means of hands or other indicators moving almost continuously while allowing a comfortable reading even in low ambient light. Furthermore, the extraordinary ingenuity of certain mechanical movements and the possibility of visualizing their components is considered fascinating by many users, especially in the case of skeleton watches allowing parts of the movement to be admired, through the crystal and the dial. Mechanical watches therefore arouse considerable enthusiasm and there is an established commercial need for mechanical watches with a dial driven by moving movement elements.
La fabrication des mouvements mécaniques est cependant complexe en sorte que les montres mécaniques sont généralement plus chères que des mouvements électroniques. C'est particulièrement le cas de mouvements mécaniques avec des grandes complications ou lorsque le mouvement doit être décoré ou usiné pour être visible en permanence derrière la glace. Les montres mécaniques affichant leurs complications sont donc presque exclusivement réservées au segment supérieur du marché des montres de luxe. En outre, seule une petite partie de la clientèle potentiellement intéressée peut disposer de la collection de montres mécaniques dont il est nécessaire de disposer pour apprécier la multitude de différentes complications proposées par les horlogers.The manufacture of mechanical movements, however, is complex so that mechanical watches are generally more expensive than electronic movements. This is particularly the case with mechanical movements with major complications or when the movement must be decorated or machined to be permanently visible behind the glass. Mechanical watches displaying their complications are therefore almost exclusively reserved for the upper segment of the luxury watch market. In addition, only a small portion of the potentially interested clientele can have access to the collection of mechanical watches that are necessary to appreciate the multitude of different complications offered by watchmakers.
Par ailleurs, la précision des mouvements mécaniques est généralement moins bonne que celle des mouvements électroniques de prix comparable. Il en résulte une certaine déception d'une partie de la clientèle qui attend une précision élevée d'une montre de luxe.Moreover, the precision of mechanical movements is generally less good than that of electronic movements of comparable price. This results in a certain disappointment from part of the clientele who expects high precision from a luxury watch.
Il existe donc un besoin établi de longue date pour une montre qui permet de résoudre ces problèmes de l'art antérieur et de répondre aux attentes parfois contradictoires du marché.There is therefore a long-established need for a watch which makes it possible to resolve these problems of the prior art and to meet the sometimes contradictory expectations of the market.
En particulier, il existe un besoin pour une montre permettant à son utilisateur d'admirer le fonctionnement du mouvement mécanique, tout en offrant une précision et un prix comparable à ceux d'une montre à quartz.In particular, there is a need for a watch allowing its user to admire the operation of the mechanical movement, while offering precision and a price comparable to those of a quartz watch.
Il existe aussi un besoin pour une montre à complications plus économique que les montres mécaniques ordinaires.There is also a need for a more economical complication watch than ordinary mechanical watches.
Il existe par ailleurs également un besoin pour une montre permettant de remplacer facilement le mouvement visualisé, afin d'admirer par exemple différents types de complications mécaniques.There is also a need for a watch that makes it possible to easily replace the movement viewed, in order to admire, for example, different types of mechanical complications.
Il existe aussi un besoin pour une montre bracelet permettant d'afficher un grand nombre d'indications différentes sans pour autant encombrer l'affichage.There is also a need for a wristwatch making it possible to display a large number of different indications without however cluttering the display.
Il existe également un besoin pour une montre-bracelet permettant de personnaliser le type d'informations affichées, et la manière de présenter ces informations.There is also a need for a wristwatch making it possible to personalize the type of information displayed, and the manner of presenting this information.
Un but de la présente invention est de proposer une montre bracelet réunissant les avantages des montres à mouvements mécaniques et ceux des montres électroniques.An object of the present invention is to provide a wristwatch combining the advantages of watches with mechanical movements and those of electronic watches.
Selon l'invention, ces buts et ces besoins sont atteints notamment au moyen d'une montre bracelet telle que définie dans la revendication indépendante 1. Des modes de réalisation préférés sont définis dans les revendications dépendantes 2 à 12.According to the invention, these aims and these needs are achieved in particular by means of a wristwatch as defined in
De plus, la revendication indépendante 13 définit un procédé correspondant, d'affichage d'informations dans une montre électronique. Les revendications dépendantes 14 et 15 définissent des réalisations particulières de ce procédé.In addition, independent claim 13 defines a corresponding method of displaying information in an electronic watch. The
Cette montre permet ainsi d'afficher un mouvement mécanique simulé aussi complexe que souhaité en évitant les coûts de fabrication d'un mouvement mécanique réel, physique et tangible. Par ailleurs, la précision de cette montre peut être aussi élevée que celle d'une montre électronique tout en offrant les animations d'une montre mécanique de catégorie supérieure.This watch thus makes it possible to display a simulated mechanical movement as complex as desired while avoiding the costs of manufacturing a real, physical and tangible mechanical movement. In addition, the precision of this watch can be as high as that of an electronic watch while offering the animations of a higher category mechanical watch.
L'invention part notamment de la constatation que les affichages électroniques modernes permettent un réalisme suffisant pour afficher une simulation crédible d'un mouvement mécanique complexe ; la résolution nécessaire aurait été impossible à obtenir il y a quelques années, ou aurait nécessité une consommation électrique incompatible avec une intégration dans une montre bracelet.The invention starts in particular from the observation that modern electronic displays allow sufficient realism to display a credible simulation of a complex mechanical movement; the necessary resolution would have been impossible to obtain a few years ago, or would have required power consumption incompatible with integration into a wristwatch.
L'invention part aussi de la constatation que la puissance de calcul des microcontrôleurs horlogers actuels (c'est-à-dire des microcontrôleurs de dimension et consommation compatibles avec une application horlogère) permet de calculer et d'afficher en temps réelle une simulation réaliste d'un mouvement mécanique complexe.The invention also starts from the observation that the computing power of current watchmaking microcontrollers (that is to say microcontrollers of size and consumption compatible with a watchmaking application) makes it possible to calculate and display in real time a realistic simulation. of a complex mechanical movement.
Le mouvement mécanique simulé s'affiche avantageusement sur toute la surface de l'affichage électronique, qui est monté bord à bord contre la face interne du réhaut ou de la lunette. De cette manière, le mouvement mécanique simulé occupe la position et les dimensions d'un mouvement mécanique réel. Des organes indicateurs, par exemple des aiguilles, des disques, des cylindres etc peuvent être affichés sur l'affichage. Des moyens de commande permettent de modifier l'affichage et de sélectionner un mouvement mécanique parmi plusieurs mouvements à disposition. Il est aussi possible d'afficher un cadran simulé, ou un vrai cadran, recouvrant totalement ou partiellement le mouvement mécanique simulé.The simulated mechanical movement is advantageously displayed over the entire surface of the electronic display, which is mounted edge to edge against the internal face of the flange or the bezel. In this way, the simulated mechanical movement occupies the position and dimensions of an actual mechanical movement. Indicating members, for example needles, discs, cylinders etc. can be displayed on the display. Control means make it possible to modify the display and to select a mechanical movement from among several available movements. It is also possible to display a simulated dial, or a real dial, totally or partially covering the simulated mechanical movement.
Dans un mode de réalisation préférentiel, l'affichage est un affichage associé à un capteur tactile, par exemple un affichage associé à un capteur tactile multitouche ou à touche simple. Cela permet d'augmenter le réalisme de la représentation ; l'utilisateur peut par exemple influencer sur la position ou le déplacement d'un composant du mouvement en appuyant ou en déplaçant la représentation de ce composant. Par exemple, il est possible de réaliser un mouvement virtuel simulé dans lequel l'utilisateur peut tourner ou arrêter les aiguilles, ou certains engrenages, ou d'autres éléments, en pressant sur leur représentation ou en déplaçant cette représentation avec une trajectoire du doigt sur l'écran.In a preferred embodiment, the display is a display associated with a touch sensor, for example a display associated with a multi-touch or single-touch touch sensor. This increases the realism of the representation; the user can for example influence the position or displacement of a component of the movement by pressing or moving the representation of this component. For example, it is possible to perform a simulated virtual movement in which the user can turn or stop the hands, or certain gears, or other elements, by pressing on their representation or by moving this representation with a trajectory of the finger on the screen.
Dans un mode de réalisation, la montre comporte une couronne à l'extérieur du boîtier et une représentation de la tige de couronne virtuelle et simulée affichée sur l'écran en regard de cette couronne. La position de la tige de couronne est modifiée par le microcontrôleur de la montre lorsque ce microcontrôleur détecte un actionnement de la couronne, de manière à simuler une action directe de la couronne sur la tige de couronne simulée. Cette couronne peut aussi être utilisée pour la mise à l'heure ou le remontage du mouvement mécanique simulé; ce mouvement peut par exemple s'arrêter après quelque temps s'il n'est pas remonté par la couronne physique.In one embodiment, the watch comprises a crown outside the case and a representation of the virtual and simulated crown stem displayed on the screen opposite this crown. The position of the crown stem is modified by the microcontroller of the watch when this microcontroller detects an actuation of the crown, so as to simulate a direct action of the crown on the simulated crown stem. This crown can also be used for setting the time or for winding the simulated mechanical movement; this movement can for example stop after some time if it is not wound up by the physical crown.
De façon analogue, l'action des boutons poussoirs physiques sur le mouvement peut être simulée en affichant un organe simulé en regard du bouton-poussoir dont la position est modifiée en cas d'actionnement du bouton-poussoir, de manière à simuler une action directe sur ledit organe simulé par ledit bouton-poussoir.Similarly, the action of the physical push buttons on the movement can be simulated by displaying a simulated organ next to the push button, the position of which is modified when the push button is actuated, so as to simulate a direct action. on said member simulated by said push-button.
Dans un mode de réalisation préférentiel, la montre-bracelet comporte en outre un accéléromètre utilisé par exemple pour augmenter le réalisme de la représentation, en la rendant dépendante des accélérations subies par la montre. Par exemple, la position d'au moins un élément du mouvement dépend d'un signal de sortie de l'accéléromètre. Il est ainsi possible de simuler le déplacement d'une masse oscillante de remontage du mouvement simulé en fonction de la montre, de visualiser les déformations du spiral ou les déplacements d'un tourbillon ou du balancier en fonction de la gravité, ou de montrer les oscillations du train d'engrenage ou d'autres composants lorsque la montre est secouée.In a preferred embodiment, the wristwatch further comprises an accelerometer used for example to increase the realism of the representation, by making it dependent on the accelerations undergone by the watch. For example, the position of at least one element of the movement depends on an output signal from the accelerometer. It is so possible to simulate the displacement of an oscillating weight for winding the simulated movement according to the watch, to visualize the deformations of the hairspring or the displacements of a tourbillon or of the balance according to gravity, or to show the oscillations of the train gear or other components when the watch is shaken.
Afin de rendre l'effet de ces accélérations réalistes, au moins certains éléments du mouvement ont une masse virtuelle utilisée pour la simulation. Le microcontrôleur calcule donc les forces et le déplacement subis par ces éléments en fonction de l'accélération mesurée, par exemple la gravité ou un choc, et affiche ces déplacements ou des déformations. Au moins certains éléments, par exemple les ressorts ou le spiral ont aussi une rigidité virtuelle et se déforment en fonction des accélérations mesurées ou des déplacements d'autres composants du mouvement simulé. L'accélération peut par exemple être mesurée selon 3 axes. Il est aussi possible de mesurer des rotations selon un ou plusieurs axes avec un gyroscope.In order to make the effect of these accelerations realistic, at least some elements of the movement have a virtual mass used for the simulation. The microcontroller therefore calculates the forces and the displacement undergone by these elements as a function of the measured acceleration, for example gravity or a shock, and displays these displacements or deformations. At least some elements, for example the springs or the hairspring also have virtual rigidity and deform as a function of the measured accelerations or the displacements of other components of the simulated movement. The acceleration can for example be measured along 3 axes. It is also possible to measure rotations along one or more axes with a gyroscope.
Dans un mode de réalisation, la marche du mouvement dépend des accélérations mesurées. Par exemple, il est possible de tenir compte de l'effet de la gravité et des chocs sur l'organe réglant pour affecter la marche de cet organe réglant ou la position d'un tourbillon. Un barillet simulé peut se décharger si l'accéléromètre ne détecte aucune accélération pour déplacer la masse oscillante, et le mouvement mécanique peut ralentir puis s'arrêter en cas de décharge.In one embodiment, the rate of movement depends on the measured accelerations. For example, it is possible to take into account the effect of gravity and of shocks on the regulating member in order to affect the rate of this regulating member or the position of a tourbillon. A simulated barrel can discharge if the accelerometer does not detect any acceleration to move the oscillating mass, and mechanical motion can slow down and then stop if discharged.
L'heure affichée par le mouvement affiché dépend donc de préférence des résultats de la simulation, en tenant compte de la rigidité des pièces ou des accélérations mesurées. Selon l'invention, l'heure du mouvement simulé est synchronisée avec l'heure déterminée par le mouvement à quartz, afin de remettre à l'heure le mouvement mécanique simulé. Cette synchronisation peut être effectuée automatiquement, par exemple de façon périodique ou en cas de variation dépassant un seuil prédéterminé, et/ou sur requête de l'utilisateur par une commande appropriée.The time displayed by the displayed movement therefore preferably depends on the results of the simulation, taking into account the rigidity of the parts or the measured accelerations. According to the invention, the time of the simulated movement is synchronized with the time determined by the quartz movement, in order to reset the simulated mechanical movement. This synchronization can be performed automatically, for example periodically or in the event of a variation. exceeding a predetermined threshold, and / or at the request of the user by an appropriate command.
Un avantage de la présente solution est qu'elle permet de simuler et d'afficher des mouvements mécaniques qui seraient impossibles ou très coûteux à fabriquer en pratique. Par exemple, il est possible d'afficher des mouvements mécaniques virtuels, simulés avec un organe réglant oscillant à une fréquence nettement plus élevée que dans un mouvement classique, et avec des organes qui tournent beaucoup plus rapidement, produisant une animation plus intéressante. Par exemple, selon l'invention, on simule des masses oscillantes ou des balanciers avec une densité très élevée, et d'autres pièces mobiles avec une densité au contraire plus faible que celle permise par les matériaux ordinaires. Par ailleurs, il est possible de simuler des pièces avec des coefficients de friction très bas, voire nuls, et avec des rigidités et des solidités très importantes, voire infinies. Enfin, on peut simuler des ressorts de barillet ou de spiral avec des contraintes de rappel nettement plus importants que dans l'art antérieur. Dans un mode de réalisation avantageux, la simulation est cependant toujours une simulation « réaliste », calculée en tenant compte de lois physiques correctes même si elle se base sur des propriétés de matériaux inexistants.One advantage of the present solution is that it makes it possible to simulate and display mechanical movements which would be impossible or very expensive to manufacture in practice. For example, it is possible to display virtual mechanical movements, simulated with a regulating organ oscillating at a much higher frequency than in a classical movement, and with organs which rotate much faster, producing a more interesting animation. For example, according to the invention, oscillating masses or balances are simulated with a very high density, and other moving parts with a density that is on the contrary lower than that permitted by ordinary materials. Furthermore, it is possible to simulate parts with very low, or even zero, coefficients of friction and with very high, or even infinite, stiffness and solidity. Finally, barrel or hairspring springs can be simulated with much greater return stresses than in the prior art. In an advantageous embodiment, the simulation is however always a “realistic” simulation, calculated taking into account correct physical laws even if it is based on properties of non-existent materials.
Dans un mode de réalisation avantageux, l'affichage ne restitue pas une simple image animée ou une vidéo préalablement enregistrée et affichée en boucle, mais une simulation calculée de la position des éléments affichés en tenant compte par exemple de la forme et de la masse simulée de ces éléments et de l'environnement (par exemple des boutons, de l'accélération etc).. Chaque image successive est donc calculée en temps réel par le microcontrôleur et générée dynamiquement en tenant compte de paramètres externes. Ceci permet d'augmenter le réalisme.In an advantageous embodiment, the display does not reproduce a simple animated image or a video previously recorded and displayed in a loop, but a calculated simulation of the position of the elements displayed taking into account for example the shape and the simulated mass. of these elements and of the environment (for example buttons, acceleration, etc.). Each successive image is therefore calculated in real time by the microcontroller and generated dynamically taking into account external parameters. This increases the realism.
L'affichage est de préférence un affichage associé à un capteur tactile à deux dimensions permettant de détecter les déplacements d'au moins un doigt selon au moins deux directions différentes, la montre comportant un circuit de traitement spécifiquement agencé pour interpréter des signaux du capteur tactile, pour sélectionner un écran parmi plusieurs écrans disponibles en fonction de ces signaux, et pour afficher cet écran sur la totalité dudit affichage. Le circuit de traitement est spécifiquement agencé de manière à provoquer un défilement d'écrans afin de remplacer durablement la carte affichée initialement par un autre écran, la direction et le sens du défilement dépendant de la direction et du sens dudit déplacement. Chaque écran affiché peut être associé à une application déterminant l'image animée affichée.The display is preferably a display associated with a two-dimensional touch sensor making it possible to detect the movements of at least one finger in at least two different directions, the watch comprising a processing circuit specifically designed to interpret signals from the touch sensor, to select a screen from among several screens available as a function of these signals, and to display this screen over the whole of said display. The processing circuit is specifically designed so as to cause scrolling of screens in order to permanently replace the map initially displayed by another screen, the direction and the direction of scrolling depending on the direction and direction of said displacement. Each screen displayed can be associated with an application determining the animated image displayed.
La montre-bracelet présente aussi l'avantage de passer d'un écran à un autre très simplement, par de simples déplacements horizontaux ou verticaux du doigt sur la glace, en tenant compte de la direction et du sens de déplacement du doigt sur l'écran.The wristwatch also has the advantage of switching from one screen to another very simply, by simple horizontal or vertical movements of the finger on the crystal, taking into account the direction and direction of movement of the finger on the screen.
Le défilement d'un écran à l'autre peut par exemple correspondre à un changement de mode de la montre. Par exemple, le remplacement d'un affichage mécanique simulé se fait par défilement d'écrans, et en remplaçant toute l'image affichée sur la montre par l'image d'un autre écran.Scrolling from one screen to another can for example correspond to a change of watch mode. For example, the replacement of a simulated mechanical display is done by scrolling through screens, and by replacing the entire image displayed on the watch with the image of another screen.

Le microcontrôleur permet d'exécuter différentes applications afin d'une part de déterminer l'heure actuelle et d'autres indications chronologiques en fonction des signaux de sortie d'un oscillateur à quartz 11 dans le boîtier, ou d'un autre signal de référence temporel. D'autre part, le microcontrôleur exécute des applications informatiques stockées dans une mémoire semi-permanente afin de contrôler les indications affichées sur l'affichage 4 en fonction des indications horaires et des commandes de l'utilisateur ou de différents senseurs. Les applications exécutées par le microcontrôleur peuvent être mises à jour par exemple au travers d'une interface sans fil non représentée, ou d'un connecteur de type micro-USB par exemple, afin de charger d'autres portions de codes permettant d'afficher d'autres indications ou les mêmes indications de façon différente.The microcontroller makes it possible to execute different applications in order on the one hand to determine the current time and other chronological indications as a function of the output signals of a
La montre peut aussi comporter plusieurs microcontrôleurs, par exemple un microcontrôleur pour contrôler l'affichage matriciel, un autre microcontrôleur pour contrôler l'interface tactile, et un microcontrôleur général pour déterminer les indications à afficher en chaque instant, selon la carte sélectionnée. Ces différents microcontrôleurs peuvent aussi être regroupés autrement.The watch can also include several microcontrollers, for example a microcontroller to control the matrix display, another microcontroller to control the touch interface, and a general microcontroller to determine the indications to be displayed at each moment, according to the selected card. These different microcontrollers can also be grouped together differently.
L'affichage 4 est de préférence un affichage associé à un capteur tactile, par exemple un affichage associé à un capteur tactile simple touche ou multitouche. Par capteur multitouche, on entend dans la présente demande un capteur tactile capable de détecter plusieurs points de contact simultanés, par exemple les déplacements simultanés de plusieurs doigts sur la surface tactile. Il est surprenant d'utiliser un écran multitouche sur la surface réduite d'une montre-bracelet, contre toute attente cette technologie s'avère pourtant efficace pour introduire des commandes complexes plus rapidement qu'avec un écran simple touche. Les électrodes de ces équipements sont de préférence associées à un circuit ou à un logiciel qui interprète ces contacts simultanés et qui les convertit en commandes exécutées par le microcontrôleur 10.The
Indépendamment de l'aspect simple touche ou multitouche, la montre se caractérise par l'affichage d'une seule icône ou carte à la fois, chaque carte remplissant tout l'écran. Les différentes cartes sont arrangées sur un seul plan et le choix d'un écran se fait uniquement par des déplacements horizontaux ou verticaux, dans le même plan, sans jamais passer à un plan différent. On évite ainsi le risque de perdre l'utilisateur dans la navigation entre plusieurs plans d'icônes ou de cartes superposés.Regardless of the single-touch or multi-touch aspect, the watch is characterized by displaying a single icon or card at a time, with each card filling the entire screen. The different cards are arranged on a single plane and the choice of a screen is made only by horizontal or vertical movements, in the same plane, without ever switch to a different plan. The risk of losing the user in navigating between several planes of icons or superimposed maps is thus avoided.
Le déroulement des programmes exécutés par le microcontrôleur 10 peut aussi être modifié en agissant sur des boutons-poussoirs monostables 41 et/ou sur la position axiale et/ou angulaire d'une couronne 42 (en option). Le numéro de référence 43 désigne des indicateurs lumineux supplémentaires, par exemple des diodes lumineuses sur la surface externe du boîtier 5 ou du bracelet. L'interface utilisateur peut aussi comporter un haut-parleur (non représenté) pour restituer des sons générés ou stockés par le microcontrôleur, une interface sans fil (non représentée) de type ZigBee ou Bluetooth par exemple, un microphone, etc.The course of the programs executed by the
La montre peut aussi comporter un haut parleur qui peut être utilisé pour restituer des sons. Dans un mode de réalisation, les sons générés et restitués dépendent de la simulation affichée, par exemple affin de restituer un « tic tac » synchronisé avec les oscillations de l'organe réglant simulé.The watch can also include a speaker which can be used to reproduce sounds. In one embodiment, the sounds generated and reproduced depend on the simulation displayed, for example in order to reproduce a “tick tock” synchronized with the oscillations of the simulated regulating organ.
L'alimentation électrique de la montre se fait avantageusement au moyen d'un accumulateur rechargeable au travers d'un connecteur micro- ou nano-USB, d'un connecteur spécifique ou propriétaire ou, dans une variante, au travers d'une interface radiofréquence.The power supply of the watch is advantageously done by means of a rechargeable battery through a micro- or nano-USB connector, a specific or proprietary connector or, in a variant, through a radiofrequency interface. .
La montre bracelet de l'invention comporte en outre avantageusement un accéléromètre 12 capable de mesurer l'accélération subie par la montre et de fournir un signal au microcontrôleur 10 dépendant de cette accélération. L'accéléromètre est de préférence un accéléromètre 3D capable de mesurer l'accélération en trois dimensions, et de déterminer la direction verticale lors des périodes d'immobilité. Cette accélération est par exemple utile pour commander et tourner l'affichage en fonction de l'orientation de la montre, et pour simuler l'effet de l'accélération sur les pièces représentées à l'écran, notamment la déformation du spiral, comme on le verra plus bas. Il est aussi possible d'utiliser un accéléromètre combiné avec un gyroscope pour mesurer l'accélération angulaire selon un ou plusieurs axes, et de simuler l'effet des rotations sur la représentation affichée.The wristwatch of the invention also advantageously comprises an

La glace 3 ferme la surface supérieure du boîtier et recouvre l'affichage matriciel numérique 4. Elle est de préférence réalisée en saphir ou dans un autre matériau inrayable, et recouverte d'un traitement antireflet. Dans un mode de réalisation préférentiel, la glace est bombée cylindrique, ou éventuellement bombée sphérique.The
Des électrodes transparentes non représentées sont déposées dans ou sous la glace 3 afin de détecter la présence d'un doigt ou d'un stylet. La technologie de détection utilise de préférence des procédés connus dans l'état de la technique, par exemple une détection capacitive.Transparent electrodes, not shown, are placed in or under the
Le microcontrôleur 10 permet d'interpréter les signaux provenant des électrodes et d'afficher sur l'affichage matriciel 4 des indications qui dépendent de ces signaux.The
L'utilisateur peut passer d'un mode d'affichage à un autre, et par exemple remplacer l'affichage de la
La
La montre-bracelet affiche donc le mouvement simulé et les indicateurs 15, 16, 17 sur toute la surface de l'affichage électronique, de manière à ce qu'il occupe la position et les dimensions d'un mouvement mécanique réel dans une montre squelette par exemple. L'utilisateur a ainsi l'impression de porter une vraie montre mécanique. Afin de renforcer le réalisme et l'impression de profondeur tridimensionnelle, le microcontrôleur 10 peut afficher des ombres sur les organes du mouvement simulé ; l'intensité et la direction des ombres peuvent aussi dépendre des mesures de lumière ambiante prises par un ou plusieurs capteurs de lumière.The wristwatch therefore displays the simulated movement and the
L'utilisateur peut remplacer un mouvement simulé affiché par un autre mouvement disponible. La
La
La couronne 42 physique à l'extérieur de la montre peut être manipulée pour remonter ou mettre à l'heure ce mouvement simulé. Dans un mode de réalisation avantageux, une tige de couronne simulée 420 est affichée sur l'écran 4 en regard de la couronne 42 ; cette tige est commandée par le microprocesseur de manière à suivre les manipulations de la couronne physique 42, donnant à l'utilisateur l'impression de réellement manipuler cette tige de couronne 420 et les organes qui lui sont liés.The
De la même façon, l'action sur les boutons-poussoirs 41 à l'extérieur du boîtier 5 se répercute avantageusement sur des organes correspondants 410 affichés sur l'écran 4, donnant à l'utilisateur l'impression de manipuler ces organes.Likewise, the action on the push-
L'utilisateur peut aussi interagir sur les éléments du mouvement simulé au travers de la surface tactile 40. Par exemple, dans un mode de réalisation, il peut déplacer ou bloquer les aiguilles 20, ou d'autres composants, simplement en déplaçant ou appuyant le doigt sur la représentation affichée de ces composants. Avantageusement, ce déplacement provoque une modification de la marche du mouvement. Par exemple, si l'utilisateur déplace une aiguille avec le doigt, l'heure affichée est durablement modifiée, et l'aiguille repart depuis l'emplacement où l'utilisateur l'a laissée. De la même façon, si un utilisateur empêche une roue ou un pignon de tourner, le mouvement simulé est arrêté pendant la durée du blocage, et la montre est ainsi retardée. Dans un mode de réalisation, l'utilisateur peut aussi retirer temporairement des composants du mouvement, par exemple des rouages, des ponts etc, au moyen du doigt ; cela permet par exemple d'observer des pièces en arrière-plan qui seraient cachées par d'autres.The user can also interact with the elements of the simulated movement through the
Dans un mode de réalisation, la montre comporte un accéléromètre 12 générant un signal de sortie qui influence la marche du mouvement simulé qui est affiché. Par exemple, des secousses mesurées par l'accéléromètre peuvent se répercuter sur le train d'engrenages qui peuvent être représentés en train de vibrer dans leurs paliers simulés. Si le mouvement comporte une masse oscillante simulée (non représentée), les oscillations de la montre peuvent provoquer une oscillation de cette masse oscillante affichée, qui peut être utilisée pour recharger un barillet virtuel simulé et remonter la montre. De la même façon, l'influence de la gravité et d'autres accélérations sur la forme du spiral virtuel et sur les oscillations du balancier virtuel peut être simulée et affichée, ainsi que les déplacements d'un tourbillon simulé par exemple.In one embodiment, the watch comprises an
Dans un mode de réalisation avantageux, le mouvement représenté est une réelle simulation d'un mouvement mécanique. Les composants simulés représentés ont donc une masse virtuelle, et des couples ou forces simulés sont transmis d'un composant à l'autre, par exemple au travers du train d'engrenages. De la même façon, certains composants tels que les ressorts ont une rigidité virtuelle. Le microcontrôleur calcule et affiche ainsi en tout temps une simulation de la position de chaque composant en fonction des interactions avec les autres composants, de l'accélération et des interactions de l'utilisateur sur la couronne 42, les boutons-poussoirs ou la glace par exemple.In an advantageous embodiment, the movement shown is a real simulation of a mechanical movement. The simulated components represented therefore have a virtual mass, and simulated torques or forces are transmitted from one component to another, for example through the gear train. Likewise, some components such as springs have virtual rigidity. The microcontroller thus calculates and displays at all times a simulation of the position of each component based on interactions with other components, acceleration and user interactions on
L'heure affichée en tout temps résulte donc de cette simulation, et peut par exemple être perturbée par les accélérations de l'organe réglant simulé ou par des imperfections du mouvement. Cette heure peut donc différer de l'heure généralement plus précise calculée par le microcontrôleur 10 sur la base des indications de l'oscillateur à quartz 11. Dans un mode de réalisation, l'heure affichée par le mouvement mécanique simulé et affiché est donc synchronisée avec l'heure du quartz, soit de manière automatique à intervalles réguliers ou lorsque la différence dépasse un seuil, ou manuellement par une interaction de l'utilisateur sur un des boutons-poussoirs 41 ou sur le capteur tactile.The time displayed at all times therefore results from this simulation, and can for example be disturbed by the accelerations of the simulated regulating organ or by imperfections in the movement. This time can therefore differ from the generally more precise time calculated by the
Il est aussi possible, dans une variante plus simple à réaliser mais moins réaliste, d'afficher une pure image d'un mouvement sur l'écran, avec une position de chaque composant et des aiguilles qui est directement déterminée d'après l'heure du quartz 11. Par ailleurs, la même montre peut offrir les deux types d'affichage, par exemple sur deux modes de représentation sélectionnables par l'utilisateur.It is also possible, in a variant that is simpler to produce but less realistic, to display a pure image of a movement on the screen, with a position of each component and of the hands which is directly determined from the time.
La montre de l'invention peut aussi être utilisée pour afficher des indications autres que des mouvements mécaniques simulés. Par exemple, la
La
La taille de chaque écran sélectionnable correspond à la taille de l'affichage 4. L'utilisateur peut modifier l'affichage en cours en remplaçant de manière permanente, jusqu'au prochain remplacement, l'écran affiché par n'importe quel autre écran sélectionné.The size of each selectable screen corresponds to the size of
Dans cet arrangement, les écrans sélectionnables sont arrangés virtuellement de manière à constituer une rangée 22 et une colonne virtuelle 21. L'utilisateur peut faire défiler les écrans dans la direction horizontale, afin de remplacer l'écran courant 23 par n'importe quel autre écran 220 à 225 de la rangée 22. De la même façon, l'utilisateur peut faire défiler les écrans verticalement afin de choisir un des écrans 210 à 213 de la colonne 21. Toutes les informations disponibles sont donc affichables par simple défilement horizontal ou vertical.In this arrangement, the selectable screens are virtually arranged to form a
Le défilement des écrans dans la direction horizontale ou verticale est obtenu en déplaçant le doigt sur la glace dans la direction et selon le sens correspondants. Ainsi l'utilisateur peut facilement consulter les écrans disponibles, et choisir un écran particulier avec de simples mouvements du doigt dans la direction horizontale ou verticale.The scrolling of the screens in the horizontal or vertical direction is obtained by moving the finger on the glass in the corresponding direction and in the corresponding direction. Thus the user can easily consult the available screens, and choose a particular screen with simple movements of the finger in the horizontal or vertical direction.
Avantageusement, l'utilisateur peut ajouter des écrans, supprimer des écrans, modifier l'ordre des écrans dans la rangée et la colonne, etc., depuis un menu particulier de la montre ou depuis un ordinateur personnel connecté à la montre. Un utilisateur peut ainsi mettre à jour un mouvement mécanique, ou ajouter une représentation supplémentaire d'un mouvement mécanique dans une montre existante.Advantageously, the user can add screens, delete screens, modify the order of the screens in the row and the column, etc., from a particular menu of the watch or from a personal computer connected to the watch. A user can thus update a mechanical movement, or add an additional representation of a mechanical movement in an existing watch.
Chaque écran peut être associé à un programme ou module informatique pour calculer les données affichées, et à des données utilisées par ce module, par exemple afin de calculer et afficher la position de chacun des composants d'un mouvement mécanique virtuel simulé. Par exemple, différents écrans correspondant à différents mouvements mécaniques peuvent être associés à différents programmes informatiques permettant de simuler ces mouvements et d'afficher les simulations correspondantes.Each screen can be associated with a computer program or module to calculate the displayed data, and with data used by this module, for example in order to calculate and display the position of each of the components of a simulated virtual mechanical movement. For example, different screens corresponding to different mechanical movements can be associated with different computer programs making it possible to simulate these movements and display the corresponding simulations.
Comme indiqué, chaque écran peut afficher une indication différente ou correspondre à un mode de fonctionnement particulier de la montre. Par exemple, les écrans 220, 221 et 222 sont utilisés pour afficher l'heure courante dans les fuseaux horaires de Tokyo, New York et Los Angeles. Les écrans 210, 211, 212 et 213 permettent d'afficher le nombre de jours, respectivement d'heures, depuis un instant donné, par exemple depuis la naissance, depuis le mariage, l'arrêt de la cigarette, etc. D'autres cartes ou écrans peuvent être utilisées pour afficher des phases de lune, un calendrier, ou d'autres indications horaires ou non horaires.As indicated, each screen may display a different indication or correspond to a particular operating mode of the watch. For example, screens 220, 221, and 222 are used to display the current time in the Tokyo, New York, and Los Angeles time zones. The
