Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It should be noted that, the previous way for the blind to learn the braille mainly depends on the touch sense to recognize, understand and distinguish the braille, which needs to carve out all the braille styles first and make the braille font model, so that the blind can recognize, understand and distinguish the braille fonts by touching the carved different braille font models, this learning way needs a large number of braille font models, and needs to touch and find out the needed braille font models from a large number of braille font models to form sentences to learn during learning, such learning efficiency is low, a large number of braille font models occupy a large physical space, are inconvenient to carry, and lack flexibility.
Subsequently, the inventor developed a reader for blind persons, which enables the blind persons to read any text, by reyikurtzier, and which mainly comprises: a digital camera for taking images of text, a small computer incorporated with the digital camera, unique software running in the small computer for recognizing text in images, and a panel-type columnar array for expressing text as corresponding braille information, etc. The blind person reader shoots characters by means of a digital camera to form an image, then specific image recognition software is used for recognizing the characters in the image, braille information corresponding to the characters is output through an internal columnar array, then the Braille information is expressed by the fact that a protruding columnar body appears on a panel at the top of the blind person reader, and the blind person can recognize the Braille by touching the protruding columnar body appearing on the panel at the top of the blind person reader. The blind person reader needs to integrate a large-scale precision device such as a digital camera, and also needs to drive a cylindrical body array which can be stretched and protruded on a panel to express braille information and the like. The digital camera, the cylindrical body array and other parts are complex, and the failure rate is high in the using process (the cylindrical body array is easy to clamp in the expansion and easy to consume energy, short in endurance and the like), so that the blind person reader is only suitable for being used in families or laboratories, is difficult to popularize commercially, and is not suitable for being used outdoors for a long time. Experimental research shows that if a pair of conductive microelectrode contacts which are level with a plane are contacted by the skin (especially fingers) of a user in the process of releasing microcurrent (current which can be safely contacted by a human body), the user can generate a tactile feeling of contacting a bump or a salient point on the plane corresponding to the skin, and the microcurrent released by the microelectrodes is called as tactile current. Based on such recognition, first, the hardware components of the tactile sensation learning machine will be briefly described. Referring to fig. 11, the shape of the touch sensing module 923 according to the embodiment of the present invention is a substrate plane (e.g., a square substrate plane shown in fig. 11) made of an insulating material, which is called an insulating material substrate. The front surface of the insulating material substrate usually has a square, rectangular, polygonal, circular shape, etc. which is beneficial for standardized production. A number of electrode units 9231 arranged in an array, for example a 10 x 10 square array in fig. 11, are arranged in the plane of the insulating substrate. Each electrode unit in the insulating material substrate comprises a pair of microelectrodes (a first microelectrode 9231a and a second microelectrode 9231 b), the electrode contact of each microelectrode is flush with the plane of the insulating material substrate, and each pair of microelectrodes can be independently controlled to release touch current, so that when the microelectrodes in the insulating material substrate are not applied with the touch current, the touch of a user on the plane of the insulating material substrate is smooth and free of concave-convex touch feeling; when a certain pair of microelectrodes or a certain part of microelectrodes in the insulating material substrate continuously release the tactility current, the skin of a user touching the tactility current on the insulating material substrate can generate specific tactility feeling, namely, the region of the microelectrodes which can feel the released tactility current has bumps or bumps.
Specifically, the tactile sensation generation module 923 is a microelectrode array composed of an insulating material substrate with a proper size and a smooth surface and a plurality of metal microelectrode units, each metal microelectrode unit is provided with two metal microelectrodes, the two metal microelectrodes in each metal microelectrode unit can be controlled to continuously output small-current electric pulses (direct current) or alternatively output small-current electric pulses (alternating current), and when the skin (such as a finger) of a user contacts the two metal microelectrodes, the small-current electric pulses (tactile currents) output by the two metal microelectrodes can flow through the skin surface of the user, so that tactile receptors of the skin of the user are stimulated, and the user can generate a feeling of touching a bump or a convex point. The embodiment can enable the user to generate the feeling intensity of touching a convex object on the skin by adjusting the frequency, the voltage amplitude and the current magnitude of the electric pulse output by the touch current, when the metal microelectrode units are finer and more precise, the metal microelectrodes arranged in a unit area are more, the touch feeling generated by the user is more exquisite when the user touches the metal microelectrode units, and the cognition of the touch feeling generated by the user on character fonts, characters and figures is more precise.
Based on the above, the present embodiment provides a tactile sensation generation device based on the principle that the tactile sensation generation module enables a user to generate a specific tactile sensation when the insulating material substrate touches a tactile current.

After the mobile phone communication connection between the touch learning machine and the mobile phone is established, part or all of contents displayed on a screen of the mobile phone can be transmitted to a touch generation device of the touch learning machine as media resources, a control module of the touch generation device can convert the media resources into control signals and transmit the control signals to a driving module, the driving module correspondingly generates driving current according to the control signals and transmits the driving current to a touch generation module, the touch generation module drives a microelectrode corresponding to the driving module to release touch current according to the driving current, so that a user touching the touch current generates touch feeling corresponding to the media resources, the user can feel contents to be expressed by the media resources through the touch feeling, and the user can also press or push a corresponding physical key to realize the functions of page turning, machine switching on and off, refreshing and the like of the media resources presented by the current touch generation module.
With reference to fig. 1, based on the understanding of the touch sensing learning machine, an embodiment of a control method of the touch sensing learning machine of the present application includes:
101. and determining a target media resource to be used for generating the touch current in the touch learning machine.
For example, the touch sensing learning machine may receive a first media resource sent by the external communication device through the communication module, and then determine the first media resource as a target media resource of the touch sensing current to be generated, so as to implement real-time transmission and translation of the first media resource of the external communication device; or, the second media resource may be stored in the haptic learning machine in advance, and then the second media resource is determined as the target media resource for generating the haptic current, so as to implement the translation of the second media resource stored in the haptic learning machine. It can be understood that the target media resource in this step includes types such as a text and a picture, and the type of the target media resource is not limited in this embodiment.
102. And converting the target media resource by using a preset conversion algorithm to generate a control signal, wherein the control signal is used for controlling a touch generation module of the touch learning machine to generate a touch current.
When the touch sensing learning machine serves as a product to serve users, the number of the electrode units arranged in the array in the touch sensing generation module of a certain model of touch sensing learning machine is determined, for example, the electrode units arranged in a 10 × 10 square array in fig. 11. Then, a preset conversion algorithm may be pre-stored in the tactile learning machine for converting the target media resource to generate a control signal corresponding to the resolution of the tactile generating module, so that the control signal is used to control the tactile generating module of the tactile learning machine to generate an accurate tactile current. Specifically, the preset conversion algorithm is a dot matrix algorithm (e.g., a character dot matrix algorithm, an image dot matrix algorithm, etc.).
103. And correspondingly generating a driving current for driving the touch sense generation module by using a driving algorithm according to the control signal.
The control signal generated in step 102 is a digital signal, and cannot or is insufficient to drive the touch sense generation module, in this step, a preset driving algorithm is used to convert the digital signal into a corresponding analog signal for output, which is called as a driving current, and the current of the driving current can be manually or automatically adjusted according to needs. The driving algorithm in this step is a conversion rule of converting a control signal of a digital signal into a driving current of an analog signal, and the conversion rule may be set or selected according to actual needs, and is not specifically limited herein.
104. The driving current is applied to the touch generation module, so that the touch generation module generates a corresponding touch current.
In this step, the driving current in step 103 is correspondingly released on the electrode units arranged in the array by the tactile sensation generation module of the tactile sensation learning machine, so that the tactile sensation generation module generates a corresponding tactile sensation current, and a user touching the tactile sensation current generates a tactile sensation corresponding to the target media resource, thereby realizing that the user can feel the content to be expressed by the media resource through the tactile sensation.
The touch learning machine of the embodiment is provided with a set of energy-saving control logic scheme aiming at the outdoor use scene of the blind user, and realizes longer endurance of the touch learning machine on the premise that the limited battery power can meet the normal use. Referring to fig. 2, another embodiment of a control method for a touch sensing learning machine of the present application includes:
201. and determining a target media resource in the touch sense learning machine to generate the touch sense current.
The execution of this step is similar to step 101 in the embodiment of fig. 1, and the repeated parts are not described again here.
202. Judging whether a starting signal aiming at a touch sensation generation module of the touch sensation learning machine is received or not, and if the starting signal aiming at the touch sensation generation module of the touch sensation learning machine is received, executing a step 203; if the starting signal of the touch feeling generation module aiming at the touch feeling learning machine is not received, the starting signal is ignored.
The touch sense generation module of the touch sense learning machine is usually in a dormant state so as to save the expenditure loss of the battery power. In view of this, even if step 201 determines the target media resource to be generated with the haptic current in the haptic learning machine, it is necessary to further determine whether the activation signal for the haptic generation module of the haptic learning machine is received, and if the activation signal for the haptic generation module of the haptic learning machine is received, it indicates that the user needs to sense the target media resource through the haptic generation module at this time; if the starting signal of the touch generation module aiming at the touch learning machine is not received, the user does not need to sense the target media resource through the touch generation module at the moment, and the battery power is not wasted to correspondingly generate the touch current. Specifically, the starting signal can be generated when a starting key on the touch-sensing learning machine is triggered; alternatively, the activation signal is generated when a sensor (e.g., an infrared proximity sensor or a film pressure sensor) determines that the user touches a tactile sensation generation module of the tactile sensation learning machine.
203. Activating the touch sense generation module in the dormant state.
When it is determined in step 202 that the user needs to sense the target media asset through the tactile sensation generation module, the tactile sensation generation module in the sleep state is activated in this step. In this step, only when a start signal for the tactile sensation generation module of the tactile sensation learning machine is received, the tactile sensation generation module in the dormant state is activated to generate a corresponding tactile sensation current, so that the consumption of the electric quantity of the battery is reduced.
204. And converting the target media resource by using a preset conversion algorithm to generate a control signal, wherein the control signal is used for controlling a touch generation module of the touch learning machine to generate a touch current.
The execution of this step is similar to step 102 in the embodiment of fig. 1, and the repeated description is omitted here.
205. And correspondingly generating a driving current for driving the touch feeling generation module by using a driving algorithm according to the control signal.
The execution of this step is similar to step 103 in the embodiment of fig. 1, and the repeated parts are not described herein again.
206. The driving current is applied to the touch sense generation module, so that the touch sense generation module generates a corresponding touch sense current.
The execution of this step is similar to the step 104 in the embodiment of fig. 1, and the repeated parts are not described herein again.
207. And when the key instruction is received and the touch generating module is in an activated state, determining a preset target instruction corresponding to the key instruction in a preset key instruction comparison table, and executing the preset target instruction.
In order to further save the limited battery power of the touch sensing learning machine of the embodiment and prolong the outdoor use time, part of keys (except the on-off key of the touch sensing learning machine and other function keys except the starting key for generating the starting signal for the touch sensing generation module) of the touch sensing learning machine can be set to be effectively triggered only when the touch sensing generation module is in the activated state, so that the calculation power expenditure and the idle execution of the control module are further reduced, and the battery power is saved.
For example, when a page turning instruction is received, that is, when a page turning key (up-turning, down-turning, left-turning or right-turning) is triggered, whether the touch sense generation module is in an activated state is determined, and if the touch sense generation module is in the activated state, the corresponding page turning instruction is executed, so that the purpose that the target media resource of the touch sense generation module generating the touch sense current is turned according to the page turning instruction is achieved, and the touch sense generation module updates and generates the corresponding touch sense current after page turning is performed.
For another example, when receiving the voice playing instruction, that is, when the voice playing key is triggered, it is determined whether the touch generating module is in an activated state, and if the touch generating module is in the activated state, the corresponding voice playing instruction is executed, so as to play the voice resource corresponding to the target media resource for which the touch generating module is generating the touch current according to the voice playing instruction.
For another example, when receiving the volume adjustment instruction, that is, when the volume button (in an up, down or specific mode) is triggered, it is determined whether the touch sense generation module is in an activated state, and if the touch sense generation module is in the activated state, the corresponding volume adjustment instruction is executed, so as to adjust the speaker playing volume of the touch sense learning machine according to the volume adjustment instruction.
For another example, when the current intensity adjustment instruction is received, that is, when the current adjustment button (in an up, down, or specific mode) is triggered, it is determined whether the touch sensation generation module is in an activated state, and if the touch sensation generation module is in the activated state, the corresponding current intensity adjustment instruction is executed, so that the touch sensation current generated by the touch sensation generation module is adjusted according to the current intensity adjustment instruction.
208. And when the tactile sensation generation module continuously generates a corresponding tactile sensation current for the same content of the target media resource and exceeds a preset time length, the tactile sensation generation module is dormant.
In order to further save the limited battery power of the touch sensing learning machine of the present embodiment and prolong the usage time in the open air, after the touch sensing generation module of the touch sensing learning machine is activated in step 203, the touch sensing generation module needs to be put to sleep in time under specific conditions. Since the step 203 activates the tactile sensation generation module of the tactile sensation learning machine based on the start signal triggered by the user, the default user will continuously generate the corresponding tactile sensation current for the same content of the target media resource after triggering the start signal each time to provide the user with tactile sensation feeling, assuming that the user needs the preset time at most to understand the meaning to be expressed by the same content, and if the preset time is longer than the preset time, it does not have meaning to generate the corresponding tactile sensation current for the same content of the target media resource, and the tactile sensation generation module needs to be dormant in time. The preset time of this step may be set according to actual needs, and is not limited herein.
In another embodiment, after the user understands that the tactile sensation generation module continues to generate the meaning expressed by the corresponding tactile sensation current for the same content of the target media resource, the user actively triggers the stop instruction (the stop button of the tactile sensation generation module is triggered), so that the tactile sensation generation module enters the sleep state.
Because the main user object oriented by the touch-sensation learning machine is the blind user, and the touch-sensation learning machine of the embodiment is the mobile terminal consuming the battery power, in order to enable the blind user to know the power condition of the touch-sensation learning machine in time and supplement the battery power of the touch-sensation learning machine in time, the embodiment also provides a power reminding scheme of the touch-sensation learning machine suitable for the blind user. Referring to fig. 3, another embodiment of a control method for a touch sensing learning machine of the present application includes:
301. when the electric quantity of the touch learning machine is lower than a preset threshold value, a voice prompt or vibration prompt suggesting timely charging is sent out.
Because the blind users can not know the residual electric quantity information through the electric quantity icon of the display screen like the users with normal eyesight, the residual electric quantity of the touch learning machine is required to be informed to the blind users in time in other perception modes. In the embodiment, the touch sensing learning machine monitors the battery capacity of the touch sensing learning machine at any moment, and one or more preset threshold values which are required to remind blind users about the current battery capacity are preset in the touch sensing learning machine. For example, 50%, 20%, 10%, etc. of the total capacity of the battery are taken as the preset threshold values. For example, when the electric quantity of the touch sensing learning machine is lower than a preset threshold, a preset electric quantity charging prompt voice is played through a loudspeaker of the touch sensing learning machine, and the electric quantity is lower than XX%, and the electric quantity is required to be supplemented in time; the vibration motor configured on the touch-sensing learning machine can vibrate for a specific number of times or in a specific direction frequency to remind a user of supplementing electricity to the touch-sensing learning machine in time, and the reminding scheme of the vibration motor is more suitable for blind users with auditory handicaps.
Because the main user object oriented by the touch-sensing learning machine is a blind user, the touch-sensing learning machine of the embodiment can be connected with the external communication equipment through the communication module, and further, related media resources of the external communication equipment are shared with the touch-sensing learning machine to express touch-sensing current. It is very necessary to accurately and timely inform the blind users whether the touch-sensing learning machine is successfully connected with the external communication equipment. Referring to fig. 4, another embodiment of a control method for a touch sensing learning machine of the present application includes:
401. when the touch learning machine is successfully connected with other external communication equipment, a voice prompt or a vibration prompt of successful connection is sent.
Because the blind user can not know whether the connection with other equipment is successful or not through the connection icon of the display screen like the user with normal eyesight, the connection state of the touch-sensing learning machine and other external communication equipment needs to be informed to the blind user in time through other modes which can be sensed. When a connection signal with an external communication device is received, namely a wireless connection key is triggered or a wired network interface detects that a network borrows, a preset device connection prompting voice is played through a loudspeaker of a touch-sensitive learning machine, and connection is tried and is waited or closed, so that a blind user can know the current state and timely reject the connection of the unintended device; of course, the specific vibration reminding can be realized by the vibration motor, and the details are not repeated. When the touch sensing learning machine is successfully connected with other external communication equipment, a voice prompt of successful connection can be sent, for example, a voice of 'successful connection with XX equipment' and the like, and a specific vibration prompt can be realized by a vibration motor, which is not described in detail. When the connection between the touch sensing learning machine and other external communication devices fails, a voice prompt of the connection failure can be sent, for example, a voice such as "failed to connect with XX device, please retry" or the like, and a specific vibration prompt can be realized by the vibration motor, which is not described again.
It should be noted that the touch sensing generation module of the touch sensing learning machine is always exposed and usually exposed to the touch of the user, and after a long time of use, the plane of the touch sensing generation module may be attached with a lot of attachments (mainly liquids such as grease and sweat generated by the skin of the finger of the user), and these attachments may affect the accuracy of the expression of the touch sensing current by the electrode units arranged in the touch sensing generation module in an array, and need to be cleaned in time. Referring to fig. 5, another embodiment of a control method of a touch sensing learning machine of the present application includes:
501. detecting whether the touch generating module meets a preset cleaning requirement, if not, executing step 502; if the touch generating module meets the preset cleaning requirement, neglecting.
The touch sensing learning machine may pre-store a preset cleaning requirement for determining that the touch sensing generation module is in a normal working state (no attachment or maximum attachment), for example, the preset cleaning requirement may be: under the normal working state, the electrode units arranged in the array in the touch generation module respectively release the resistance value range when sensing current with specific intensity. In the embodiment, whether the touch sensation generation module meets the preset cleaning requirement is detected regularly in a state that a user does not trigger a starting signal to activate the touch sensation generation module, for example, a specific voltage is applied to each group of electrode units arranged in an array in the touch sensation generation module, and then corresponding resistance values are respectively calculated; if the resistance values of all the electrode units are within the resistance value range recorded by the preset request, the touch generation module meets the preset cleaning requirement, and it can be determined that the positions of all the electrode units do not have attachments which affect normal use.
502. And sending out a prompt for suggesting that the touch feeling generation module is cleaned.
When the resistance value of the part of the electrode units is determined not to be within the resistance value range recorded by the preset request requirement in step 501, it is proved that the touch sensation generation module does not meet the preset cleaning requirement, and it can be determined that the position of the part of the electrode units has the attachments. The reminding of this step can make the user in time clean the touch area surface that the module took place for the sense of touch, gives the better use experience of user.
