Definitions
- This invention relates to navigation devices and to graphical user interface methods for navigation devices.
- Illustrative embodiments of the invention relate to portable navigation devices (so-called PNDs), in particular PNDs that include Global Positioning System (GPS) signal reception and processing functionality.
- PNDs portable navigation devices
- GPS Global Positioning System
- Other embodiments relate, more generally, to any type of processing device that is configured to execute navigation software so as to provide route planning, and preferably also navigation, functionality.
- Portable navigation devices that include GPS (Global Positioning System) signal reception and processing functionality are well known and are widely employed as in-car or other vehicle navigation systems.
- GPS Global Positioning System
- a modern PNDs comprises a processor, memory (at least one of volatile and non-volatile, and commonly both), and map data stored within said memory.
- the processor and memory cooperate to provide an execution environment in which a software operating system may be established, and additionally it is commonplace for one or more additional software programs to be provided to enable the functionality of the PND to be controlled, and to provide various other functions.
- these devices further comprise one or more input interfaces that allow a user to interact with and control the device, and one or more output interfaces by means of which information may be relayed to the user.
- output interfaces include a visual display and a speaker for audible output.
- input interfaces include one or more physical buttons to control on/off operation or other features of the device (which buttons need not necessarily be on the device itself but could be on a steering wheel if the device is built into a vehicle), and a microphone for detecting user speech.
- the output interface display may be configured as a touch sensitive display (by means of a touch sensitive overlay or otherwise) to additionally provide an input interface by means of which a user can operate the device by touch.
- Devices of this type will also often include one or more physical connector interfaces by means of which power and optionally data signals can be transmitted to and received from the device, and optionally one or more wireless transmitters/receivers to allow communication over cellular telecommunications and other signal and data networks, for example Wi-Fi, Wi-Max GSM and the like.
- PND devices of this type also include a GPS antenna by means of which satellite-broadcast signals, including location data, can be received and subsequently processed to determine a current location of the device.
- the PND device may also include electronic gyroscopes and accelerometers which produce signals that can be processed to determine the current angular and linear acceleration, and in turn, and in conjunction with location information derived from the GPS signal, velocity and relative displacement of the device and thus the vehicle in which it is mounted.
- electronic gyroscopes and accelerometers which produce signals that can be processed to determine the current angular and linear acceleration, and in turn, and in conjunction with location information derived from the GPS signal, velocity and relative displacement of the device and thus the vehicle in which it is mounted.
- location information derived from the GPS signal, velocity and relative displacement of the device and thus the vehicle in which it is mounted.
- PNDs The utility of such PNDs is manifested primarily in their ability to determine a route between a first location (typically a start or current location) and a second location (typically a destination). These locations can be input by a user of the device, by any of a wide variety of different methods, for example by postcode, street name and house number, previously stored "well known" destinations (such as famous locations, municipal locations (such as sports grounds or swimming baths) or other points of interest), and favourite or recently visited destinations.
- the PND is enabled by software for computing a “best” or “optimum” route between the start and destination address locations from the map data.
- a “best” or “optimum” route is determined on the basis of predetermined criteria and need not necessarily be the fastest or shortest route.
- the selection of the route along which to guide the driver can be very sophisticated, and the selected route may take into account existing, predicted and dynamically and/or wirelessly received traffic and road information, historical information about road speeds, and the driver's own preferences for the factors determining road choice (for example the driver may specify that the route should not include motorways or toll roads).
- the device may continually monitor road and traffic conditions, and offer to or choose to change the route over which the remainder of the journey is to be made due to changed conditions.
- Real time traffic monitoring systems based on various technologies (e.g. mobile phone data exchanges, fixed cameras, GPS fleet tracking) are being used to identify traffic delays and to feed the information into notification systems.
- PNDs of this type may typically be mounted on the dashboard or windscreen of a vehicle, but may also be formed as part of an on-board computer of the vehicle radio or indeed as part of the control system of the vehicle itself.
- the navigation device may also be part of a hand-held system, such as a PDA (Portable Digital Assistant) a media player, a mobile phone or the like, and in these cases, the normal functionality of the hand-held system is extended by means of the installation of software on the device to perform both route calculation and navigation along a calculated route.
- PDA Portable Digital Assistant
- Route planning and navigation functionality may also be provided by a desktop or mobile computing resource running appropriate software.
- the Royal Automobile Club provides an on-line route planning and navigation facility at http://www.rac.co.uk, which facility allows a user to enter a start point and a destination whereupon the server to which the user's PC is connected calculates a route (aspects of which may be user specified), generates a map, and generates a set of exhaustive navigation instructions for guiding the user from the selected start point to the selected destination.
- the facility also provides for pseudo three-dimensional rendering of a calculated route, and route preview functionality which simulates a user travelling along the route and thereby provides the user with a preview of the calculated route.
- the user interacts with the navigation device to select the desired calculated route, optionally from a list of proposed routes.
- the user may intervene in, or guide the route selection process, for example by specifying that certain routes, roads, locations or criteria are to be avoided or are mandatory for a particular journey.
- the route calculation aspect of the PND forms one primary function, and navigation along such a route is another primary function.
- PNDs During navigation along a calculated route, it is usual for such PNDs to provide visual and/or audible instructions to guide the user along a chosen route to the end of that route, i.e. the desired destination. It is also usual for PNDs to display map information on-screen during the navigation, such information regularly being updated on-screen so that the map information displayed is representative of the current location of the device, and thus of the user or user's vehicle if the device is being used for in- vehicle navigation.
- An icon displayed on-screen typically denotes the current device location, and is centred with the map information of current and surrounding roads in the vicinity of the current device location and other map features also being displayed. Additionally, navigation information may be displayed, optionally in a status bar above, below or to one side of the displayed map information, examples of navigation information include a distance to the next deviation from the current road required to be taken by the user, the nature of that deviation possibly being represented by a further icon suggestive of the particular type of deviation, for example a left or right turn.
- the navigation function also determines the content, duration and timing of audible instructions by means of which the user can be guided along the route. As can be appreciated a simple instruction such as "turn left in 100 m" requires significant processing and analysis.
- user interaction with the device may be by a touch screen, or additionally or alternately by steering column mounted remote control, by voice activation or by any other suitable method.
- a further important function provided by the device is automatic route recalculation in the event that: a user deviates from the previously calculated route during navigation (either by accident or intentionally); real-time traffic conditions dictate that an alternative route would be more expedient and the device is suitably enabled to recognize such conditions automatically, or if a user actively causes the device to perform route re-calculation for any reason.
- a route to be calculated with user defined criteria; for example, the user may prefer a scenic route to be calculated by the device, or may wish to avoid any roads on which traffic congestion is likely, expected or currently prevailing.
- the device software would then calculate various routes and weigh more favourably those that include along their route the highest number of points of interest (known as POIs) tagged as being for example of scenic beauty, or, using stored information indicative of prevailing traffic conditions on particular roads, order the calculated routes in terms of a level of likely congestion or delay on account thereof.
- POIs points of interest
- Other POI-based and traffic information-based route calculation and navigation criteria are also possible.
- route calculation and navigation functions are fundamental to the overall utility of PNDs, it is possible to use the device purely for information display, or "free-driving", in which only map information relevant to the current device location is displayed, and in which no route has been calculated and no navigation is currently being performed by the device. Such a mode of operation is often applicable when the user already knows the route along which it is desired to travel and does not require navigation assistance.
- Devices of the type described above for example the 720T model manufactured and supplied by TomTom International B.V., provide a reliable means for enabling users to navigate from one position to another.
- a user's interaction with a navigation device is not limited to a single input i.e. key-press.
- Some inputs necessary to control a navigation device consist of a sequence of inputs, particularly where it is necessary to input data to the navigation device. Examples of instances where it is necessary to provide a sequence of inputs to a navigation device include entering a new destination, varying route selection criteria, i.e. to determine if an alternative route is better for the user, and including a diversion in a route.
- route guidance from a navigation device providing a sequence of user inputs to the navigation device can be inconvenient, particularly when those inputs are provided within one or more menus of the navigation device i.e. a display of the navigation device is utilised for menu or data input rather than route guidance.
- a presently preferred embodiment of the present invention provides a navigation device, comprising a memory, a display device and a toggle display module arranged to receive a toggle input from a user and, in response, to store information in the memory indicative of a display state of the navigation device and to output on the display device a driving view representing one or more geographic features proximal to a current location of the navigation device.
- a further preferred embodiment of the invention provides a method of operating a graphical user interface for a navigation device, comprising outputting a screen of a graphical user interface on a display device, receiving a first toggle input from a user and, in response, storing information indicative of a display state of the navigation device and outputting on the display device a driving view representing one or more geographic features proximal to a current location of the navigation device.
- the screen of the display device is one of a menu providing one or more menu options or a data input screen.
- the menu or the data input screen may occupy substantially the entire display device.
- Yet another embodiment of the present invention relates to computer software comprising one or more software modules operable, when executed in an execution environment, to cause a processor to operating a graphical user interface for a navigation device, comprising outputting a screen of a graphical user interface on a display device, receiving a first toggle input from a user and, in response, storing information indicative of a display state of the navigation device and outputting on the display device a driving view representing one or more geographic features proximal to a current location of the navigation device.

- NAVSTAR the GPS incorporates a plurality of satellites which orbit the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can relay their location to any number of receiving units.
- the GPS system is implemented when a device, specially equipped to receive GPS data, begins scanning radio frequencies for GPS satellite signals. Upon receiving a radio signal from a GPS satellite, the device determines the precise location of that satellite via one of a plurality of different conventional methods. The device will continue scanning, in most instances, for signals until it has acquired at least three different satellite signals (noting that position is not normally, but can be determined, with only two signals using other triangulation techniques). Implementing geometric triangulation, the receiver utilizes the three known positions to determine its own two-dimensional position relative to the satellites. This can be done in a known manner. Additionally, acquiring a fourth satellite signal will allow the receiving device to calculate its three dimensional position by the same geometrical calculation in a known manner. The position and velocity data can be updated in real time on a continuous basis by an unlimited number of users.

- Each satellite 120 as part of its data signal transmission 160, transmits a data stream indicative of that particular satellite 120.
- the GPS receiver device 140 generally acquires spread spectrum GPS satellite signals 160 from at least three satellites 120 for the GPS receiver device 140 to calculate its two-dimensional position by triangulation. Acquisition of an additional signal, resulting in signals 160 from a total of four satellites 120, permits the GPS receiver device 140 to calculate its three-dimensional position in a known manner.

- the direction control 610 may be a circular-shaped button or displayed icon, or may be a rotary control.
- the direction control 610 is capable of being actuated in a plurality of directions.
- the direction control 610 shown in Figure 6 is capable of being actuated in four directions (up, down, right and left), although more directions are possible, such as up-left etc.
- the function keys 620-640 include a back key 620 which may be used to delete an input or, when in a menu system, to go up a level of menu i.e. back to the immediately previous menu.
- Option key 630 may be used to display one or more options currently available for a current screen.
- a menu button 640 causes the display of a menu screen such as a main menu, for example when in a driving view of the navigation device. It will be realised that the input unit 600 shown in Figure 6 may include other controls, such as additional controls for the navigation device 200 and that embodiments of the invention are not limited to the controls shown in Figure 6.
- Embodiments of the invention include a driving view toggle means 650, the operation of which will now be explained in more detail.
- FIG. 7 shows a data input screen of a navigation device which is used to search for a Point of Interest (POI).
- POI Point of Interest
- Some navigation devices accept a textual input for such a data input screen e.g. through a touch-sensitive display screen.
- a user utilises the direction control 610 to navigate a highlighted cursor around the keys shown in Figure 7 and to select desired alphanumeric keys in sequence.
- the input may be provided verbally.
- a time to complete such a task may be relatively long.
- some users of navigation devices 200 may wish to interact with the navigation device 200 whilst either receiving route guidance from the navigation device 200 or viewing surround roads on the navigation device in the "free-driving" mode referred to earlier.
- Embodiments of the present invention allow a user to quickly return to the driving view of the navigation device 200 and then to return to complete a previously-started interaction with the navigation device 200.
- Embodiments of the invention include a toggle means, such as a driving view toggle key (DVTK) 650 which may either be a hardware control, such as a physical button, a graphically displayed control i.e. displayed on the display screen 240, or a verbal command.
- DVTK driving view toggle key
- the toggle means 650 When the toggle means 650 is activated by the user the navigation device 200 is arranged to toggle between an incomplete task and the driving view.
- the driving view is understood to be a mode in which one or more geographical features corresponding to the location of the navigation device are displayed on the display screen 240.
- activation of the DVTK 650 causes the TDM 490 to save a current state of the navigation device 200 and return the display screen 240 to the driving view mode.
- activation of the DVTK 650 causes the TDM 490 to display on the display device 240 a previously displayed screen, as will be explained.
- Figure 8 illustrates a method 800 according to an embodiment of the invention.
- the method 800 is performed by embodiments of the TDM 490 i.e. the method 800 is operatively performed by the processor 210 of the navigation device 200.
- the method 800 may be performed at any time whilst the navigation device 200 is operational. However, it is intended that the method will generally be performed either whilst the navigation device 200 is operative in the driving view mode (providing route guidance or free driving) or whilst the navigation device 200 is displaying a menu or data input screen
- the method 800 starts and, in step 810, it is determined whether the toggle means has been activated by the user.
- the toggle means is a key or graphically displayed icon
- the toggle means is activated by contact from the user, although other forms of toggle activation are also possible.
- the toggle means may correspond to a voice command spoken by the user, such as "Toggle”, “Toggle to driving view” or simply “Driving view”.
- the toggle means is the DVTK 650, although it will be realised that the invention is not limited in this respect. If the DVTK 650 has not been operated, then the method returns to step 810 i.e.
- step 810 it is determined whether the navigation device 200 is currently operative in the driving view, for example either providing route guidance or "free driving". If the navigation device 200 is currently operative in the driving view, then the method moves to step 850. In step 850 it is determined whether menu information exists in the memory 230 of the navigation device 200.
- the menu information indicates a state of the navigation device when the DVTK 490 was previously activated.
- the menu information may indicate the menu or screen displayed on the display device 240 when the DVTK 650 was operated.
- the menu may be a menu within a sequence of menus i.e.
- the displayed menu may not normally be accessible directly from the driving view because it is a sub-menu.
- the menu information may store any user inputs entered into the navigation device but which had not been accepted by the navigation device 200 when the DVTK 650 was operated.
- the user had partially entered a POI name into the data input screen shown in Figure 7, but had not yet caused the navigation device 200 to accept the data input i.e. by pressing the "Done" icon shown in Figure 7, activation of the DVTK 650 causes the data input to be saved as part of the menu information stored in the memory 230.
- the menu information saved by the TDM 490 may alternatively be indicative of a verbal input provided to the navigation device 200.
- a user may have selected an option of the navigation device 200 to verbally input a destination.
- a first part of the verbal input may correspond to a state or city of the destination and a second part of the verbal input may correspond to a street of the destination.
- the TDM 490 may save menu information indicative of the first part of the verbal destination entry when the DVTK 650 is activated before the second part of the destination is verbally entered.
- step 850 if menu information exists in the memory 230 then the method moves to step 860. However, if no menu information exists in the memory 230, the method moves to step 880. Menu information may not exist in the memory because the DVTK 650 has not previously been operated by the user to cause the TDM 490 to store the menu information in the memory 230. Alternatively, the TDM 490 may be arranged to delete previously stored menu information from the memory 230 after a predetermined period of time, for example one hour, although other time periods may be used. In step 880, if no menu information exists in the memory 230 then an error is output by the navigation device 200. The error may be displayed on the display screen 240 as a message informing the user that no menu information exists in the memory 230.
- step 860 if the menu information exists in the memory 230, the menu information is retrieved by the TDM 490.
- the menu information allows a screen previously displayed when the DVTK 490 was last activated to be displayed again on the display screen 240.
- the screen may include that user input allowing the user to complete the incomplete task without re-entering the user input. The method then ends.
- step 830 menu information is stored in the memory 230 by the TDM 490 indicating the display state of the navigation device 200.
- the menu information may indicate the currently displayed screen identifying the menu or data input screen displayed at the time of DVTK 650 activation and information indicating any incomplete data input provided to the navigation device 200 but not accepted by the navigation device 200 when the DVTK 650 is activated.
- step 840 the display screen is caused to return to the driving view.
- the user In the driving view the user is provided with a visual display of their surroundings i.e. geographic features in the vicinity such as roads etc and may also be provided with visual and/or audible route guidance.
- the DVTK 650 and TDM 490 enable the user to quickly return to the driving view whilst preserving the current state of the navigation device for later direct return via a further operation of the DVTK 650.
- step 910 a user activates a main menu of the navigation device, for example by activation of the menu key 640 shown in Figure 6.
- step 920 a user selects a first sub menu from the main menu and then from that submenu activates a data input screen, such as that shown in Figure 7.
- Figure 9 describes operation of the invention with reference to a sub menu and data input screen, it will be realised that this is merely exemplary.
- the data input screen may receive the user's input to complete one or more data fields with alphanumeric data.
- step 940 the user enters data into the displayed data input screen.
- the user activates the DVTK 650 which causes the TDM 490 to save menu information in the memory 230 of the navigation device 200 and return the display screen 240 to outputting the driving view, as shown in Figure 9 in step 970.
- the menu information may indicate the screen displayed at the time of DVTK 650 activation, such as by storing an ID of the input screen and information indicating the data input received by the screen which has not yet been accepted by the navigation device 200.
- the driving view shows geographic features, particularly roads in the vicinity of the navigation device 200 and other associated information, such as an upcoming turn which should be taken by the user.
- the user wishing to complete the data entry activates the DVTK 650 a second time to cause the TDM 490 to load the stored menu information and return the output of the display screen 240 directly to the screen displayed at the time of the first activation of the DVTK 650.
- the TDM 490 loads the data input screen in the example of Figure 9 without requiring the user to return to the main and first sub-menu, as in steps 90 and 920.
- the data input screen contains the previously received user input, thereby allowing the user to more quickly complete the task in progress at the time of DVTK 650 activation.
- teachings of the present invention provide an arrangement whereby a user may quickly toggle between a driving view of the navigation device in which geographic features such as roads are indicated to the user, and a menu or data input screen of the navigation device.
- the navigation device may utilise any kind of position sensing technology as an alternative to (or indeed in addition to) GPS.
- the navigation device may utilise using other global navigation satellite systems such as the European Galileo system. Equally, it is not limited to satellite based but could readily function using ground based beacons or any other kind of system that enables the device to determine its geographic location.
