Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
A touch identification method is applied to terminal equipment and comprises the following steps: detecting whether a user touches a touch screen of the terminal equipment or not; if the user touches 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 placing direction, the touch area and the touch position so as to identify the touch operation.
As shown in fig. 1, fig. 1 is a schematic flow chart of a touch recognition method provided in an embodiment of the present application, where the touch recognition method is applied to a terminal device, and a specific flow may be as follows:
s101, detecting whether a user touches the touch screen of the terminal device, if so, executing the following step S102, and if not, re-detecting.
In this embodiment, the touch operation mainly includes clicking and pressing, and when the touch screen in the terminal device starts the touch function, the touch screen detects whether there is an external force operation such as clicking or pressing on the touch screen, and if so, the user is considered to have performed the touch operation. The touch screen mainly comprises two types, namely a resistance type touch screen and a capacitance type touch screen, wherein the resistance type touch screen is controlled by pressure induction, and the capacitance type touch screen works by current induction of a human body.
And 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 a three-dimensional space, and referring to fig. 2, a three-dimensional space coordinate system xyz may be established with a ground plane (i.e., a horizontal plane when the display screen is placed horizontally) as a plane where an xy axis is located, a direction where gravity and a center of the ground are located as a Z axis, and a screen center of the display screen as a coordinate origin O, and the angle of the terminal device in the xyz coordinate system is determined, that is, the placement angle.
Since the actual contact area is not a single point but an area every time the user clicks or presses on the touch screen with a finger, the touch position is usually the coordinate position of an area surrounded by a plurality of pixel points, i.e., the area of the area surrounded by the pixel points.
And S103, determining a touch reporting position according to the placing direction, 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 placing angle is a preset angle or not;
if the placing angle is a preset angle, taking the touch position as a touch reporting position;
and if the placing angle is not the preset angle, determining the touch reporting position according to the placing angle and the touch area.
In this embodiment, the preset angle may be that the z-axis is 0 °, the xy plane is an arbitrary angle, that is, the terminal device is placed horizontally, in a normal case, when the touch screen detects the contact position in the horizontal direction, the deviation phenomenon is less, and the detected touch position can be directly reported, and when the contact position in the non-horizontal direction (for example, in the vertical direction) is detected, the deviation phenomenon is more obvious, so that the touch position cannot be directly reported, and needs to be adjusted.
Further, the step of determining the touch reporting position according to the placement angle and the touch area may specifically include:
obtaining a deviation value range corresponding to the placing 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 the touch reporting position according to the touch position and the deviation value range.
In this embodiment, the offset value range may be stored in advance, for example, a user may set a corresponding offset value range for each placement angle in advance, or the offset value range may be calculated by a preset algorithm, for example, a calculation method for storing an offset value range related to a placement angle in the terminal device in advance. 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 fact that the contact area between the finger of the user and the touch screen is too small is indicated, the finger belongs to abnormal contact, and when the actual touch area is larger than or equal to the preset area, the fact that the finger of the user and the touch screen belongs to normal contact is indicated.
For example, the step of "determining the touch reporting position according to the touch position and the deviation value range" may specifically include:
determining a touch central point corresponding to the touch position;
determining an estimated touch position according to the touch central 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 predetermined radius is set by default, and is generally related to the area of the human finger. When the touch area is too small, in order to improve the detection accuracy, the touch center point of the touch position can be determined firstly, then the touch center point is used as the center of a circle, the preset radius is used as the radius to draw a circular area, and the circular area is used as the estimated touch position, so that a proper touch area can be ensured, and the identification 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 a return operation within a preset time length, acquiring the current error times, and updating the current error times;
when the updated current error frequency reaches a preset frequency, generating a contact correction interface;
touch point correction is performed on the touch screen based on the touch point correction interface.
In this embodiment, the corresponding operation mainly depends on the display content at the touch reporting position on the display interface, and the display content may be a certain application icon, a certain key, or other content. The preset time period may be 2 seconds or 3 seconds, which is generally less than the time period required for a user to normally read a page. The current error frequency refers to the accumulated frequency of triggering the return operation within the preset time length in the past, and the updating method is to increase the current error frequency once, generally, for the first detection, the current error frequency is 0.
After the terminal device executes a certain corresponding operation according to the touch reporting position, if the user triggers a return operation in a short time, it is very likely that the touch reporting position is not the position that the user wants to touch, and there is a judgment error, and once the judgment error occurs for a large number of times, for example, a preset number of times (for example, 10 times), it can be considered that the touch screen cannot normally sense and a touch point needs to be corrected. The contact point correction interface may be an interface for guiding a user to perform contact point position correction in the horizontal direction and the vertical direction, and some prompt information may be provided thereon.
Therefore, the touch identification method provided by the embodiment is applied to a terminal device, and is used for detecting whether a user touches a touch screen of the terminal device, determining the current placement angle of the terminal device, the touch position and the touch area of the touch operation if the user touches the touch screen of the terminal device, and determining the touch reporting position according to the placement direction, the touch area and the touch position to identify the touch operation, so that when a contact offset phenomenon occurs on the touch screen, the contact position detection can still be accurately performed, the detection accuracy is high, and the detection effect is good.
According to the method described in the above embodiments, the present embodiment will be further described in detail by applying the touch recognition method to a terminal device.
Referring to fig. 3, the flow of the touch recognition method includes:
s201, detecting whether a user touches the touch screen of the terminal device, if so, executing the following step S202, and if not, 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 placing angle is a preset angle, if so, taking the touch position as a touch reporting position, and if not, executing the following step S204.
And S204, acquiring a deviation value range corresponding to the placing angle, and 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.
And S205, summing the touch position and the deviation value range to obtain a touch reporting position.
S206, determining a touch central point corresponding to the touch position, determining an estimated touch position according to the touch central point and a preset radius, and then summing the estimated touch position and the deviation value range to obtain a touch reporting position.
S207, corresponding operation is executed according to the touch reporting position, then whether a user triggers a return operation within a preset time length is detected, if yes, the following step S208 is executed, and if not, no operation is executed.
S208, obtaining the current error times, updating the current error times, generating a touch point correction interface when the updated current error times reach the preset times, and performing touch point correction on the touch screen based on the touch point correction interface.
For example, when a user clicks a touch screen, the terminal device may detect a current placement angle of the terminal device, a touch position and a touch area of the user, and then determine which strategy is adopted to determine a reporting position for reporting according to the placement angle, for example, when the terminal device is detected to be horizontally placed, the touch position may be directly reported, when the terminal device is not horizontally placed, the touch position needs to be adjusted and then reported, for example, when the touch area is smaller, an estimated touch position with a proper area may be estimated first, and then the estimated touch position is reported after being corrected, and when the touch area is proper, the touch position may be directly corrected and then reported. After the terminal device executes the corresponding operation according to the reported position, it may further determine whether the reported position is the true touch position of the user, for example, by detecting whether the user triggers a return operation in a short time, and count the number of times of accumulation of the previous true touch position of the non-user, and once the number of times of accumulation is large, it indicates that the sensing error of the touch screen is large, at this time, the touch point of the touch screen is corrected, so as to ensure the normal operation of the touch sensing.
According to the methods described in the above embodiments, the present embodiment will be further described from the perspective of a touch recognition device, which may be specifically implemented as a stand-alone entity.

The touch screen mainly comprises two types, namely a resistance type touch screen and a capacitance type touch screen, wherein the resistance type touch screen is controlled by pressure induction, and the capacitance type touch screen works by current induction of a human body.

Since the actual contact area is not a single point but an area every time the user clicks or presses on the touch screen with a finger, the touch position is usually the coordinate position of an area surrounded by a plurality of pixel points, i.e., the area of the area surrounded by the pixel points.
