Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
The touch recognition method is applied to the terminal equipment and comprises the following steps: detecting whether a user touches a touch screen of the terminal equipment or not; if the user performs touch operation on the touch screen of the terminal equipment, determining the current placement angle of the terminal equipment, and the touch position and the touch area of the touch operation; and determining a touch reporting position according to the placement angle, the touch area and the touch position so as to identify the touch operation.
As shown in fig. 1, fig. 1 is a flowchart of a touch recognition method according to an embodiment of the present application, where the touch recognition method is applied to a terminal device, and the specific flow may be as follows:
s101, detecting whether a user touches the touch screen of the terminal equipment, if so, executing the following step S102, and if not, re-detecting.
In this embodiment, the touch operation mainly includes clicking and pressing, when the touch screen in the terminal device opens the touch function, it detects whether there is an external force operation such as clicking or pressing on the touch screen, and if there is an external force operation, the user is considered to perform the touch operation. The touch screen mainly comprises a resistive touch screen and a capacitive touch screen, wherein the resistive touch screen is controlled by using pressure induction, and the capacitive touch screen is operated by using current induction of a human body.
S102, determining the current placement angle of the terminal equipment, and the touch position and the touch area of the touch operation.
In this embodiment, the placement angle is an angle in three-dimensional space, referring to fig. 2, a plane where the xy axis is located may be a ground plane (i.e., a horizontal plane when the display screen is placed horizontally), a direction where gravity and the earth center are located is a Z axis, a screen center of the display screen is taken as an origin O of coordinates, a three-dimensional space coordinate system xyz is established, and an angle of the terminal device in the xyz coordinate system is determined to be the placement angle.
Since the actual contact area is not a single point but an area each time a user clicks or presses with a finger on the touch screen, the touch position is typically the coordinate position of an area surrounded by a plurality of pixel points, that is, the area of the area surrounded by the pixel points.
S103, determining a touch reporting position according to the placement angle, the touch area and the touch position so as to identify the touch operation.
For example, the step S103 may specifically include:
judging whether the placement angle is a preset angle or not;
if the placement angle is a preset angle, the touch position is used as a touch reporting position;
if the placement angle is not the preset angle, determining a touch reporting position according to the placement angle and the touch area.
In this embodiment, the preset angle may be that the z-axis is 0 °, and the xy-plane is an arbitrary angle, that is, the terminal device is placed horizontally, in general, when the touch screen detects the contact position in the horizontal direction, the offset phenomenon is less, and the detected touch position can be directly reported, and when the contact position in the non-horizontal direction (such as the vertical direction) is detected, because the offset phenomenon is obvious, the touch position cannot be directly reported, and adjustment is required.
Further, the step of determining the touch report position according to the placement angle and the touch area may specifically include:
acquiring a deviation value range corresponding to the placement angle, and judging whether the touch area is not smaller than a preset area;
if the touch area is not smaller than the preset area, summing the touch position and the deviation value range to obtain a touch reporting position;
and if the touch area is smaller than the preset area, determining a touch reporting position according to the touch position and the deviation value range.
In this embodiment, the deviation value range may be stored in advance, for example, the user may set a corresponding deviation value range for each placement angle in advance, or may be calculated by a preset algorithm, for example, a calculation method of a deviation value range related to a placement angle may be stored in advance in the terminal device. The preset area is mainly used for defining whether the touch area is normal or not, when the actual touch area is smaller than the preset area, the contact area between the user finger and the touch screen is too small, abnormal contact is caused, and when the actual touch area is larger than or equal to the preset area, normal contact is caused between the user finger and the touch screen.
For example, the step of determining the touch report position according to the touch position and the deviation value range may specifically include:
determining a touch center point corresponding to the touch position;
determining a predicted touch position according to the touch center point and a preset radius;
and summing the estimated touch position and the deviation value range to obtain a touch reporting position.
In this embodiment, the preset radius is set by human default, which is generally related to the area of the human finger. When the touch area is too small, in order to improve the detection accuracy, a touch center point of the touch position can be determined first, then a circular area is drawn by taking the touch center point as a circle center and the preset radius as a radius, and the circular area is taken as a predicted touch position, so that a proper touch area can be ensured, and the recognition accuracy is improved.
Further, after the above step S103, the touch recognition method may further include:
executing corresponding operation according to the touch reporting position;
after the corresponding operation is executed, detecting whether a user triggers a return operation within a preset time length;
if the user triggers the return operation within the preset time, the current error times are obtained, and the current error times are updated;
when the updated current error times reach preset times, generating a contact correction interface;
and carrying out contact correction on the touch screen based on the contact correction interface.
In this embodiment, the corresponding operation mainly depends on the display content at the touch report position on the display interface, where the display content may be a certain application icon, a certain key, or other content. The preset duration may be 2 seconds or 3 seconds, which is typically less than the duration required for the user to read a page normally. The current error frequency refers to the accumulated frequency of triggering the return operation within the preset time in the past, the update method is to increase once based on the current error frequency, and the current error frequency is usually 0 for the first detection.
When the terminal device performs a corresponding operation according to the touch reporting position, if the user triggers a return operation in a short time, it is highly likely that the touch reporting position is not the position that the user wants to touch, and a judgment error exists, and once the number of times of the judgment error is large, for example, when the number of times reaches a preset number of times (for example, 10 times), it can be considered that the touch screen cannot normally sense, and contact correction is required. The contact correction interface may be an interface for guiding the user to perform contact position correction in the horizontal direction and the vertical direction, and some prompt information may be provided thereon.
As can be seen from the foregoing, the touch recognition method provided in this embodiment is applied to a terminal device, and is used to detect whether a user performs a touch operation on a touch screen of the terminal device, if the user performs a touch operation on the touch screen of the terminal device, determine a current placement angle of the terminal device, and a touch position and a touch area of the touch operation, and determine a touch reporting position according to the placement angle, the touch area and the touch position, so as to recognize the touch operation, thereby, when a contact offset phenomenon occurs on the touch screen, the contact position detection can still be accurately performed, and the detection accuracy is high and the detection effect is good.
The present embodiment will be further described in detail with the application of the touch recognition method to a terminal device according to the method described in the above embodiment.
Referring to fig. 3, the touch recognition method includes the following steps:
s201, detecting whether a user performs touch operation on the touch screen of the terminal equipment, if the user performs touch operation on the touch screen of the terminal equipment, executing the following step S202, and if the user does not perform touch operation on the touch screen of the terminal equipment, re-detecting.
S202, determining the current placement angle of the terminal equipment, and the touch position and the touch area of the touch operation.
S203, judging whether the placement angle is a preset angle, if the placement angle is the preset angle, taking the touch position as a touch reporting position, and if the placement angle is not the preset angle, executing the following step S204.
S204, acquiring a deviation value range corresponding to the placement angle, judging whether the touch area is not smaller than a preset area, if so, executing the following step S205, and if not, executing the following step S206.
S205, summing the touch position and the deviation value range to obtain a touch reporting position.
S206, determining a touch center point corresponding to the touch position, determining an estimated touch position according to the touch center point and a preset radius, and then summing the estimated touch position and the deviation value range to obtain a touch reporting position.
S207, executing corresponding operation according to the touch reporting position, detecting whether a user triggers a return operation within a preset time period, if so, executing the following step S208, and if not, not executing any operation.
S208, acquiring current error times, updating the current error times, generating a contact correction interface when the updated current error times reach preset times, and carrying out contact correction on the touch screen based on the contact correction interface.
For example, when the user clicks the touch screen, the terminal device may detect the current placement angle, and the touch position and the touch area of the user, and then determine, according to the placement angle, what strategy is adopted to determine the reporting position for reporting, for example, when the terminal device is detected to be placed horizontally, the reporting may be directly performed on the touch position, and when the terminal device is not placed horizontally, the reporting may be performed after the touch position needs to be adjusted, for example, when the touch area is smaller, an estimated touch position with a suitable area may be estimated first, and then the estimated touch position may be corrected and then reported, and when the touch area is suitable, the reporting may be performed directly after the touch position is corrected. After the terminal device executes the corresponding operation according to the reporting position, it can further determine whether the reporting position is the real touch position of the user, for example, by detecting whether the user triggers the return operation in a short time, and counting the accumulated times of the real touch positions of the non-user in the past, once the accumulated times are more, it indicates that the induction error of the touch screen is larger, and at this time, the touch point correction is performed on the touch screen to ensure the normal operation of the touch induction.
According to the method described in the above embodiments, the present embodiment will be further described from the perspective of a touch recognition device, which may be embodied as a separate entity.
Referring to fig. 4, fig. 4 specifically describes a touch recognition device provided by an embodiment of the present application, where the touch recognition device is applied to a terminal device, and the terminal device may include a device with a touch screen, such as a mobile phone, a tablet computer, a personal PC, and the like, and may include: a detection module 10, a determination module 20 and an identification module 30, wherein:

In this embodiment, the touch operation mainly includes clicking and pressing, when the touch screen in the terminal device opens the touch function, it detects whether there is an external force operation such as clicking or pressing on the touch screen, and if there is an external force operation, the user is considered to perform the touch operation. The touch screen mainly comprises a resistive touch screen and a capacitive touch screen, wherein the resistive touch screen is controlled by using pressure induction, and the capacitive touch screen is operated by using current induction of a human body.
(2) Determination module 20

Since the actual contact area is not a single point but an area each time a user clicks or presses with a finger on the touch screen, the touch position is typically the coordinate position of an area surrounded by a plurality of pixel points, that is, the area of the area surrounded by the pixel points.
(3) Identification module 30
And the recognition module 30 is configured to determine a touch reporting position according to the placement angle, the touch area and the touch position, so as to recognize the touch operation.

and a second determining unit 33, configured to determine a touch reporting position according to the placement angle and the touch area if the placement angle is not a preset angle.
In this embodiment, the preset angle may be that the z-axis is 0 °, and the xy-plane is an arbitrary angle, that is, the terminal device is placed horizontally, in general, when the touch screen detects the contact position in the horizontal direction, the offset phenomenon is less, and the detected touch position can be directly reported, and when the contact position in the non-horizontal direction (such as the vertical direction) is detected, because the offset phenomenon is obvious, the touch position cannot be directly reported, and adjustment is required.

The preset area is mainly used for defining whether the touch area is normal or not, when the actual touch area is smaller than the preset area, the contact area between the user finger and the touch screen is too small, abnormal contact is caused, and when the actual touch area is larger than or equal to the preset area, normal contact is caused between the user finger and the touch screen.
