detailed description

In order for those skilled in the art to better understand the technical solution of the present disclosure, the touch recognition method, the touch device and the operating method thereof provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a flow chart of a touch recognition method for a touch device according to an embodiment of the present disclosure. The touch recognition method for a touch device of the present disclosure can be applied to a touch device with a touch screen, such as a mobile phone, a tablet computer, and the like. The touch device may include a touch screen provided with at least one operation key, a memory storing key driving information of the at least one operation key, a processor, a driving circuit and a counter. The touch recognition method of the touch device of the present disclosure includes: step S3: in response to the vibration information in at least one touch button area, sending a program trigger instruction; for the vibration information in any of the touch button areas, the following steps are adopted Acquisition: Step S1: Determine the area of the touch button in response to the touch signal, and generate a driving signal; Step S2: Determine the vibration information according to the driving signal, and the vibration information includes at least the number of vibrations.

In the touch recognition method of the present disclosure, a program trigger instruction is sent in response to vibration information in at least one touch button area, where the vibration information includes at least the number of vibrations. Specifically, when the user touches the touch key area, the touch key area touched by the user is determined in response to the touch signal, and the driving circuit generates a driving signal, and the driving signal drives the vibrator to vibrate. When the user no longer touches the area of the touch key, in response to disappearance of the touch signal, the driving signal will also be interrupted. According to the corresponding driving signal (for example, including a plurality of driving waveforms) during the period when the user touches the touch key area, the vibration information sent by the vibrator can be determined, so as to obtain the vibration times of the vibrator. In response to the vibration information in at least one touch button area, the processor sends a program triggering instruction. Thus, when the user releases the operation button when the number of vibrations of the operation button reaches the preset number of times, the system sends a program trigger instruction to perform the operation specified by the corresponding number of vibrations of the operation button. As a result, the user can operate conveniently without particularly relying on visual aids. For example, the following application scenarios: replace the right-click function according to the number of vibrations, one vibration indicates a click operation, two vibrations indicate a right-click operation, three vibrations indicate renaming, and more than three vibrations indicate icon dragging, etc. At the same time, the user can also perform corresponding operations according to the number of vibrations in the case of the off-screen. For example, the user can set the off-screen operation according to personal needs, and will press and hold a certain position A (which can overlap with the unlock position or be a separate area) differently. The number of vibrations is set to correspond to the broadcast time, call the emergency contact, turn on the camera and other operations; after the setting is completed, without turning on the screen, the user can press and hold the specific position A and release the press after the preset number of vibrations You can let the mobile phone and other devices complete operations such as opening the camera.

Optionally, the step S1 of determining the area of the touch key and generating the driving signal in response to the touch signal further includes steps S11 to S13:

S11: Determine whether the touch operation on the touch screen represents an effective operation on any one of the at least one operation key in the at least one touch key area;

S12: In response to determining that the touch operation represents an effective operation on any one of the at least one operation key in the at least one touch key area, execute S13, otherwise, jump to S11;

S13: Based on the key driving information of the at least one operating key stored in the memory, control the driving circuit to send a corresponding driving signal, and add 1 to the counter.

As shown in FIG. 2 , it shows a specific flowchart of a touch recognition method for a touch device according to an embodiment of the present disclosure. Wherein S11 to S13 are the operation process of determining the area of the touch button in response to the touch signal, and generating a driving signal to make the vibrator vibrate once.

Further, according to the driving signal, the step S2 of determining the vibration information further includes steps S14 to S15:

S14: After a predetermined period of time, determine whether the touch operation on the touch screen still exists. If the touch operation still exists, then enter the loop execution S13, that is, continue to send a driving signal through the drive circuit to make the vibrator emit continuous vibration, and the vibration timer will increase by 1 each time; if the touch operation no longer exists, it means that the user is no longer Touch the corresponding touch button area, then execute the subsequent step S15 sequentially;

S15: the processor combines the current count of the counter with the previously stored record in the memory as the current record and stores it in the memory; and

S16: The processor outputs vibration information according to the current record in the memory, where the counter in the current record corresponds to the number of vibrations in the vibration information.

Thus, the processor can obtain the number of vibrations in the vibrator from the storage, and send a program trigger instruction based on the number of vibrations.

As shown in FIG. 3 , it shows the touch button area of the touch device in the embodiment of the present disclosure. The touch button area also includes a confirm button and a cancel button. Further, between step S15 and step S16, the touch recognition method may also include:

S17: judging whether the touch operation on the touch screen represents an effective operation to the determined button;

S18: In response to the touch operation on the touch screen indicating an effective operation on the determination button, the processor sends a program trigger instruction to the touch device according to the current vibration information; otherwise, determine whether the touch operation on the touch screen indicates an effective operation on the cancel button ;

S19: In response to the touch operation on the touch screen indicating an effective operation on the cancel button, clear the current record in the memory and jump to S11, otherwise, use the current record in the memory as the previous storage record and jump to S11.

Thus, the user can confirm or cancel the operation corresponding to the current number of vibrations through the confirm button and the cancel button.

Optionally, judging whether the touch operation on the touch screen represents an effective operation on the operation button/the OK button/the cancel button includes: detecting whether the touch position of the touch operation falls within the effective area of the button and/or Or detect whether the pressure value of the touch operation is greater than a preset pressure threshold. Specifically, the manner in which the user touches the operation keys of the touch screen of the device may be a light touch type or a force threshold type. For example, the light touch type means that as long as it is detected that the user touches the operation area of the operation button of the touch screen, the vibration is started, and once the user leaves the screen, the vibration stops, and the number of vibrations is recorded. The applied force threshold formula means that the vibration is only started when the user touches the screen and the applied pressure exceeds the set threshold F _th , and the vibration is stopped when the user applies a force less than the threshold F _th , and the number of vibrations is recorded. Different operation button modes can be adopted for different operation buttons, thereby enriching the user's operation options and individual requirements.

To determine whether the touch operation is an effective operation on the button, different buttons (operation button/OK button/cancel button) can use the same or different judgment methods. For example, the touch operation that detects the touch operation can be used to judge the operation button. Whether the position falls within the effective area of the button, and when judging the button/cancel button, it is used to detect whether the pressure value of the touch operation is greater than the preset pressure threshold. This judgment method can not only ensure the operation fluency of the recognition method, but also ensure the accuracy. Of course, these judgment methods can be customized according to the individual needs of users.

Optionally, at least one operation key includes a plurality of operation keys; and for at least two of the plurality of operation keys, the driving waveforms in the driving signals are different. The difference in driving waveforms can include different wavelengths and different peak values. Therefore, different vibration feedbacks can be generated when different keys are touched. For example, when the A1 key is pressed, it vibrates once every 0.5 seconds, and the vibration intensity is high. The A2 button vibrates every 1 second when it is pressed, and the vibration intensity is the lowest, which helps users experience good tactile feedback during operation.

Optionally, the touch device further includes at least one vibrator disposed outside the touch screen, and the driving signal is configured to drive the at least one vibrator to vibrate. Therefore, before step S11, the touch recognition method further includes: using the at least one vibrator to generate vibration, and through multiple trainings, obtain the result of the driving signal of the at least one vibrator when the area where the at least key is located vibrates. The corresponding button driving information is stored in the memory.

The driving information of the operating keys is obtained in advance through a time domain inversion algorithm and stored in a memory for calling by the processor. Specifically, the time-domain inversion algorithm needs to collect and calibrate the equipment in advance to obtain the driving information of vibration in each area and store it in the database. When subsequent needs are required, the database data driver can be directly called. Take the local vibration of button A1, and the number of vibrators is N as an example; first, an external vibrator is used to generate vibration at button A1, and the vibration information A1_N is collected at the center point of each vibrator, and the time domain inversion operation is performed on A1_N, and the The processed waveforms are stored in the database, and the driving waveforms of each key area are obtained by sequentially collecting and processing them and stored in the database. When the external vibrator is used to vibrate the button A1, different forces can be applied there at the same time to obtain a calibration database. In actual operation, the calibration database can be called to drive according to the force applied by the user. Thus, the accuracy of the operation method can be ensured, and defects such as lack of tactile feedback can be avoided.

Thus, the key driving information corresponding to the driving signal of the at least one vibrator when the area where the key is located vibrates can be obtained through pre-training, which is convenient for subsequent calling of the processor.

According to another aspect of the present disclosure, it provides a touch device 1, including a touch screen 11 provided with at least one touch button area, a drive circuit 13, a processor 12, and at least one vibrator 14, wherein the processor 12 determine the touch button area in response to the touch signal, and start the drive circuit 13 to generate and send a drive signal; the at least one vibrator 14 continues to vibrate according to the drive signal, and the processor 12 detects the drive signal and determine the vibration information, the processor 12 sends a program trigger instruction in response to the vibration information in at least one touch key area, wherein the vibration information includes at least the number of vibrations.

As shown in FIG. 4 , it shows a flow chart of operating a single operation button according to an exemplary embodiment of the present disclosure. The touch device 1 detects the touch information in real time. When there is data input, the system judges whether to start the operation key. If the pressure value is less than the threshold F _th or is not in the area of the operation key, no operation is performed and the detected touch data is returned. If When the pressure value reaches the threshold value F _th and the touch area is the area for operating keys, the touch information (such as including touch orientation, touch pressure value, key sequence, etc.) Call out the driving information of the corresponding operation button in the good database and drive the subsequent driving circuit according to the driving information. After the driving circuit is started, it sends out the corresponding driving waveform to drive the vibrator to make the screen vibrate.
