In this embodiment, the executing body of the touch positioning method may be an electronic whiteboard with a touch function. In practice, the execution main body may detect the key state of the target key by detecting a level change of the interface of the target key. As an example, if it is detected that the level of the interface changes from a low level to a high level, the key state may be determined as a triggered state. As another example, if it is detected that the level of the interface changes from a high level to a low level and then to a high level, the key state may also be determined as a triggered state.
Fig. 4 is a schematic circuit diagram for detecting a key state of a target key according to an embodiment of the present disclosure. As shown in FIG. 4, KEY is the target KEY, R is a resistor, and R may have a resistance of 10 kilo-ohms. And 3.3V is the power supply voltage of the target key. The KEY may be an automatic reset KEY, and when the KEY is pressed, the circuit is turned on, and the level at the interface is changed from a high level to a low level. When the KEY is stopped, the circuit is opened and the level at the interface changes from low to high. Here, if the target key is an auto-reset key, the execution body may detect a level change of the interface during a process from pressing to popping up of the target key, thereby obtaining a key state of the target key.
In practice, the key states may generally include a triggered state and an unactuated state. Generally, the triggered state of the target key generally refers to a state in which the level of the interface of the target key changes. The inactive state of the target key generally refers to the state of the key other than the activated state.
Optionally, detecting a key state of the target key includes: first, a level change of an interface of a target key is detected. Then, in response to detecting that the level of the interface changes from high level to low level and then to high level, the key state is determined to be the triggered state.
Here, in the case where the target key is an automatic reset key, when it is detected that the level of the interface of the target key changes from high level to low level and then to high level, or when it is detected that the level of the interface of the target key changes from low level to high level and then to low level, it may be determined that the key shape of the target key is in the triggered state.
Optionally, detecting a key state of the target key includes: first, a level change of an interface of a target key is detected. Then, in response to detecting that the level of the interface changes from a high level to a low level, the key state is determined to be a triggered state.
Here, the execution main body may determine that the key shape of the target key is in the triggered state when detecting that the level of the interface of the target key changes, for example, changes from a high level to a low level.
The control instruction is used for controlling the target application to present a positioning interface, and the positioning interface presents information used for guiding a user to execute touch positioning operation.
The target state is usually a triggered state.
The target application is generally an application for positioning a touch position of an electronic whiteboard.
Here, after receiving the control instruction, the target application may open the positioning interface and project the positioning interface onto the electronic whiteboard through the projector based on the control instruction.
The positioning interface may be presented with information for guiding a user in performing a touch positioning operation. As an example, the positioning interface may be presented with information for guiding a user to trace on the outline of the projection area. At this time, the touch positioning operation is an operation of tracing a line on the outline of the projection area.
Optionally, the positioning interface presents information for guiding a user to perform a touch positioning operation, including: the positioning interface presents a plurality of contour positioning points and information for guiding a user to click on the plurality of contour positioning points, wherein the plurality of contour positioning points are used for determining the position of the projection area. In practice, the positioning interface usually presents contour positioning points of the projection area and information for guiding the user to click on the contour positioning points of the projection area. The contour localization points described above are typically points used to determine the location of the projection region. At this time, the touch positioning operation may be: and clicking the contour positioning point of the projection area.
As an example, the contour positioning points may be four vertices of the projection area.
As another example, the contour positioning point may also be four vertices of the projection area plus a center point of the projection area.

The P0-P8 are distributed on the projection area 502, and the projection area 502 is located on the electronic whiteboard 501. Wherein, P0 is the center point of the projection area, P1-P4 are the vertexes of the projection area, and P5-P8 are the midpoints of four sides of the projection area.
Here, after the electronic whiteboard issues the control instruction to the target application, a positioning interface may be projected on the electronic whiteboard. In this way, the user can perform touch positioning operation on the electronic whiteboard based on the guidance information presented by the positioning interface to realize touch positioning.
Optionally, based on the control instruction, receiving a touch positioning operation performed by a user based on a positioning interface to implement touch positioning, including: and selecting contour positioning points from a plurality of contour positioning points presented by the positioning interface, and executing information prompt operation on the selected contour positioning points. And responding to the detected click of the user on the contour positioning point, acquiring the coordinate value of the contour positioning point, selecting the contour positioning point which is not selected from the plurality of contour positioning points, and continuing to execute the information prompt operation until all the contour positioning points are clicked. And determining the coordinate value of each touch point on the electronic whiteboard according to the coordinate values of the plurality of contour positioning points, so as to realize touch positioning.
The information prompting operation generally refers to an operation of displaying, near the contour positioning point, information for prompting a user to click the contour positioning point.
Here, each contour positioning point may be displayed on the positioning interface, and a prompt message for prompting the user to click the contour positioning point is displayed by flashing beside one contour positioning point. After the user clicks the contour positioning point, the positioning interface displays prompt information for prompting the user to click the contour positioning point in a flashing mode beside the other contour positioning points until all the contour positioning points are clicked. In this way, the electronic whiteboard can acquire the position of each contour positioning point on the electronic whiteboard and the coordinate value under the target coordinate system. And the target coordinate system is a display coordinate system of the terminal equipment where the target application is located. And the electronic whiteboard can obtain the mapping relation between the coordinate system of the electronic whiteboard and the target coordinate system based on the positions of the same contour positioning points in the electronic whiteboard and the coordinate values under the target coordinate system. Therefore, the coordinate values of all the touch points on the electronic whiteboard under the target coordinate system can be calculated and obtained based on the mapping relation. Therefore, the touch position on the electronic whiteboard can be positioned.
It should be noted that, the electronic whiteboard may also only obtain the position of the contour positioning point clicked by the user on the electronic whiteboard, and then send the obtained position of the contour positioning point on the electronic whiteboard to the target application. And enabling the target application to obtain a mapping relation between the coordinate system of the electronic whiteboard and the target coordinate system based on the positions of the same contour positioning points in the electronic whiteboard and the coordinate values under the target coordinate system. Therefore, the coordinate values of all the touch points on the electronic whiteboard under the target coordinate system can be calculated and obtained based on the mapping relation. Therefore, the touch position on the electronic whiteboard can be positioned.
According to the method provided by the embodiment, the target application is controlled to present the positioning interface when the key state is the target state by detecting the state of the target key. The user can conveniently and quickly open the positioning interface by pressing the target key, so that touch positioning operation is executed based on the guiding information of the positioning interface to realize touch positioning. The efficiency of positioning the touch position on the electronic whiteboard is improved.
