Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of touch technology, and more particularly to a touch data processing method and device. Background Art
[0002] Capacitive pens are currently widely used in electronic devices such as tablets and laptops. However, the first electrode of the capacitive stylus is currently a slender structure.

[0055] This description may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present disclosure.
[0056] Below, the embodiments of the present application are described in detail with reference to the accompanying drawings.
[0057] like Figure 1 As shown, an embodiment of the present application provides a touch data processing method, including:
[0058] S1: In response to a touch operation input by a touch object on a screen, determining a first touch position, and obtaining a first angle between the touch object and a horizontal plane, and a second angle between the screen and the horizontal plane;
[0059] S2: determining a tilt direction of the touch object relative to the screen based on a first electrode signal and a second electrode signal output by the touch object, wherein the first electrode signal is output by a first electrode on the touch object, and the second electrode signal is output by a second electrode on the touch object;
[0060] S3: Processing the first touch position based on the first angle, the second angle, and the tilt direction to obtain a second touch position, wherein a distance between the second touch position and the actual touch position of the touch object is smaller than a distance between the first touch position and the actual touch position of the touch object.
[0061] In this embodiment, the touch body can be, but is not limited to, a touch pen, for example, a capacitive pen, etc., and this embodiment of the application does not limit this. When the user uses the touch body to perform input operations on the screen, such as clicking, drawing, writing, etc. on the screen with the touch body, the screen system responds to the touch operation input by the user on the screen and calculates the first touch position. The first touch position does not match the actual touch position of the touch body on the screen, and there is a first distance between the two positions. At the same time, the system will obtain the first angle between the touch body and the horizontal plane, and the second angle between the screen and the horizontal plane. The first angle value can be sent to the system by the touch body, or input by the user, or collected by the device system, which may be specific. The second angle can be collected by the device and sent to the screen system, etc., which may be specific. In this embodiment, the touch object is provided with a first electrode and a second electrode. Both the first electrode and the second electrode transmit electrode signals to the screen. The screen system determines the tilt direction of the touch object relative to the screen based on the first electrode signal output by the first electrode and the second electrode signal output by the second electrode on the touch object. For example, the tilt direction of the touch object relative to the screen is determined based on the order in which the two electrode signals are received. After the screen system obtains the first angle, the second angle, and the tilt direction, it processes the first touch position based on these three parameters, such as by calibration or updating, to obtain a second touch position. The second touch position is located at a second distance from the actual touch position of the touch object. This second distance is less than the first distance, meaning that the second touch position is closer to the actual touch position than the first touch position.
[0062] Based on the above scheme, it can be seen that in this embodiment, the tilt direction of the touch object relative to the screen is determined by obtaining the first electrode signal and the second electrode signal, and then the angle between the touch object and the horizontal plane and the angle between the screen and the horizontal plane are respectively obtained. The first touch position is processed in combination with the determined tilt direction to obtain the second touch position. The second touch position can be obtained by calibrating the first touch position, or can be calculated based on the first touch position, or can be directly calculated based on the first angle, the second angle, and the tilt direction, etc., and the embodiments of the present application are not limited to this. After the screen system obtains the second touch position, it will display the second touch position as the final touch point position on the screen, so that the displayed position matches the actual touch position, improving touch and display accuracy, and thus improving the user experience.
[0063] In one embodiment, obtaining a first angle between the screen and a horizontal plane, and a second angle between the touch object and the horizontal plane, includes:
[0064] S4: Obtaining a first angle between the touch-sensitive object and a horizontal plane based on angle information collected by a gyroscope of the touch-sensitive object;
[0065] S5: Obtain a second angle between the screen and the horizontal plane based on angle information collected by a gyroscope of the device where the screen is located.
[0066] In this embodiment, a first gyroscope is provided within the touch sensor, and a second gyroscope is provided within the device housing the screen. The first angle is determined by the screen system based on angle information collected by the first gyroscope, while the second angle is determined by the screen system based on angle information collected by the second gyroscope. This approach utilizes existing components within the device and touch sensor to collect angle information and determine the first and second angles, eliminating the need for additional components and reducing costs. Furthermore, using the gyroscope to collect angle information ensures accuracy, laying the foundation for subsequently determining the second touch position and ensuring accuracy in subsequent calculations.
[0067] In another embodiment, the method further comprises:
[0068] S6: Determine a third angle between the touch object and the screen based on the first angle and the second angle;
[0069] The processing of the first touch position based on the first angle, the second angle, and the tilt direction includes:
[0070] S7: Processing the first touch position based on the third angle and the tilt direction.
[0071] The determining of the third angle between the touch object and the screen based on the first angle and the second angle includes:
[0072] S8: Calculating the difference between the first angle and the second angle;
[0073] S9: Determine a third angle between the touch object and the screen based on the difference.
[0074] For example, in this embodiment, the first and second angles are both measured relative to a horizontal plane. Therefore, the difference between the first and second angles can be calculated to obtain a third angle between the touchscreens. When the screen system processes a first touch position based on the first and second angles and the tilt direction to obtain a second touch position, the screen system processes the first touch position based on the third angle and the tilt direction to obtain the second touch position.
[0075] Specific, combined Figure 3 As shown, the angle between the screen and the horizontal plane is determined to be DEG A using the angle information collected by gyroscope 1, and the angle between the touch screen and the horizontal plane is determined to be DEG B using the angle information collected by gyroscope 2. Then, the third angle (Tilt) = DEG B - DEG A can be calculated through trigonometric functions.
[0076] Further, such as Figure 2 As shown, the determining the tilt direction of the touch body relative to the screen based on the first electrode signal and the second electrode signal output by the touch body includes:
[0077] S10: Determine a first receiving position of the first electrode signal on the screen;
[0078] S11: Determine a second receiving position of the second electrode signal on the screen;
[0079] S12: Determine the signal receiving time of the first electrode signal and the second electrode signal;
[0080] S13: Determine the tilt direction of the touch object relative to the screen based on the signal receiving time, the first receiving position, and the second receiving position of the first electrode signal and the second electrode signal.
[0081] For example, in this embodiment, the touch-sensitive body is elongated, i.e., pen-shaped, and has a first electrode and a second electrode spaced apart along its length. When a user uses the touch-sensitive body to input a touch operation on the screen, both the first electrode and the second electrode transmit electrode signals to the screen. Upon receiving the first electrode signal transmitted by the first electrode, the screen system determines the receiving position of the signal on the screen, i.e., the first receiving position. Simultaneously, upon receiving the second electrode signal transmitted by the second electrode, the screen system determines the receiving position of the signal on the screen, i.e., the second receiving position. The screen system also determines the reception time of the first and second electrode signals. Based on the reception times and reception positions of the two electrode signals, a line vector can be determined. For example, if the first electrode signal is obtained first and then the second electrode signal, the line vector can be determined based on this sequential relationship and the reception positions of the two electrode signals. Based on this line vector, the screen system can accurately determine the tilt direction of the touch-sensitive body relative to the screen.
[0082] For example, Figure 4 As shown, the first receiving position of the first electrode signal on the screen is A(X, Y), and the second receiving position of the second electrode signal on the screen is C(X, Y). The line vector is the line between the second receiving position and the first receiving position, and the direction is from the second receiving position to the first receiving position.
[0083] Furthermore, in one embodiment, the method further includes:
[0084] S14: Obtaining a first mapping relationship table constructed by actual touch point positions corresponding to different touch operations applied by the touch-sensitive object on the screen during a historical period, touch point positions determined by the device in response to the touch operations, angles between the touch-sensitive object and the screen, and tilt directions of the touch-sensitive object relative to the screen;
[0085] S15: Determine the second touch position in combination with the first mapping relationship table.
[0086] In this embodiment, the screen system obtains actual touch point locations corresponding to different touch operations performed on the screen by a touch-sensitive object during a historical period. The actual touch point locations can be user-entered data, such as touch position data collected by the user during a touch experiment test for different touch operations performed on the screen by the touch-sensitive object. The screen system also obtains the touch point location, the angle between the touch-sensitive object and the screen, and the tilt direction of the touch-sensitive object relative to the screen, determined by the device in response to the touch operation. The system associates and stores the obtained data, such as the actual touch point location, the touch point location, the angle between the touch-sensitive object and the screen, and the tilt direction of the touch-sensitive object relative to the screen corresponding to the same touch operation, to generate a first mapping table. After obtaining the first mapping table, the screen system processes the first touch position based on a third angle and tilt direction to obtain a second touch position. The system then processes the first touch position based on the third angle, tilt direction, and the first mapping table to determine the second touch position.
[0087] Specifically, the processing the first touch position based on the first angle and the tilt direction to obtain the second touch position includes:
[0088] S16: Determine a third angle between the screen and the touch object based on the difference between the first angle and the second angle;
[0089] S17: performing matching in the first mapping relationship table based on the third angle, the tilt direction, and the first touch position to determine a corresponding actual touch point position;
[0090] S18: updating the first touch position based on the actual touch point position to obtain a second touch position.
[0091] For example, if both the first and second angles are determined based on a horizontal plane, the screen system will calculate the angle between the screen and the touch-sensitive object, i.e., the third angle, based on the difference between the first and second angles. The system then matches the third angle, the tilt direction, and the first touch position in the first mapping table to determine the corresponding actual touch point position. The first touch position is then updated based on the determined actual touch point position to obtain the second touch position.
[0092] In another embodiment, the method further comprises:
[0093] S19: Obtaining a second mapping relationship table based on different touch point position compensation values, angles between the touch object and the screen, and tilt directions;
[0094] S20: Determine the second touch position in combination with the second mapping relationship table.
[0095] In this embodiment, the screen system obtains the touch point position compensation value for the touch position determined for different touch operations input by the touch body, as well as the angle between the touch body and the screen. The touch point position compensation value has a one-to-one correspondence with the touch position calculated by the screen system in response to the touch operation, such as the first touch position, that is, each touch position has a corresponding touch point position compensation value. The touch point position compensation value also has a one-to-one correspondence with the angle between the touch body and the screen when the touch operation is output, that is,
[0096] The touch point position compensation value corresponding to the same touch point, the angle between the touch object and the screen, and the tilt direction of the touch object relative to the screen are then associated and stored to generate a second mapping relationship table. After obtaining the second mapping relationship table, when the screen system processes the first touch position based on the third angle and tilt direction to obtain the second touch position, it processes the first touch position based on the third angle, tilt direction, and the second mapping relationship table to determine the second touch position.
[0097] Specifically, the processing of the first touch position based on the first angle, the second angle, and the tilt direction to obtain the second touch position includes:
[0098] S21: determining a third angle between the screen and the touch object based on a difference between the first angle and the second angle;
[0099] S22: performing matching in the second mapping relationship table based on the third angle to determine a corresponding touch point position compensation value;
[0100] S23: Calibrate the first touch position based on the tilt direction and the touch point position compensation value to obtain the second touch position.
[0101] For example, as mentioned above, the first angle and the second angle are both angles determined based on the horizontal plane, so the screen system will calculate the angle between the screen and the touch body based on the difference between the first angle and the second angle, that is, the third angle. Then, based on the third angle, a match is performed in the second mapping relationship table to determine the corresponding touch point position compensation value. After that, the screen system performs corresponding position compensation on the first touch position vector based on the tilt direction and the touch point position compensation value, and finally obtains the second touch position. At this point, the screen system can use the second touch position as the touch reporting point position to perform a matching response, such as displaying a trajectory, triggering a corresponding application, and so on.
