Referring to fig. 2, a system architecture diagram for an application of a touch positioning method according to an embodiment of the present application is provided.
As shown in fig. 2, the system architecture may include an electronic whiteboard 201, a target key 2011 disposed on the electronic whiteboard, a terminal device 202 with a target application 2021 installed, and a projector 203. The terminal device 202 is electrically connected to the electronic whiteboard 201 and the projector 203, respectively.
An electronic whiteboard 201 for detecting a key state of the target key 2011; in response to the key state of the target key 2011 being the target state, a control instruction for controlling the target application 2021 to present a positioning interface is sent to the target application 2021, so that the user performs a touch positioning operation based on the positioning interface projected onto the electronic whiteboard, so as to implement touch positioning, where the positioning interface presents information for guiding the user to perform the touch positioning operation.

Example two
Referring to fig. 3, an embodiment of the present application provides a touch positioning method, including:
step 301, detecting a key state of a target key.
The target key may be a preset key.
In practice, the target key is usually fixed on the electronic whiteboard. The target key is typically electrically connected to the controller of the electronic whiteboard through an interface, such as a General-Purpose Input/Output (GPIO) interface.
In this embodiment, the execution body of the touch positioning method may be an electronic whiteboard with a touch function. In practice, the execution subject 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 the triggered state. As another example, if it is detected that the level of the interface changes from high to low to high, the key state may also be determined as the triggered state.
Fig. 4 is a schematic circuit diagram of detecting a key state of a target key according to an embodiment of the present application. As shown in fig. 4, KEY is a target KEY, R is a resistor, and the resistance value of R may be 10 kiloohms. 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 changes from high level to low level. When KEY is stopped, the circuit is opened, and the level at the interface is changed from low level to high level. Here, if the target key is an automatic reset key, the execution body may detect a level change of the interface in a process from pressing to bouncing of the target key, so as to obtain a key state of the target key.
In practice, key states may generally include a triggered state and an unactivated state. In general, 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 unactivated state of a target key generally refers to a key state 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 a high level to a low level and then to a high level, it is determined that the key state is a triggered state.
Here, in the case where the target key is the automatic reset key, when it is detected that the level of the interface of the target key changes from the high level to the low level and then to the high level, or when it is detected that the level of the interface of the target key changes from the low level to the high level and then to the low level, it may be determined that the key shape of the target key is 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 body may determine that the key shape of the target key is the activated state when it is detected that the level of the interface of the target key changes, for example, when it changes from the high level to the low level.
And step 302, in response to the key state of the target key being the target state, a control instruction is sent to the target application.
The control instruction is used for controlling the target application to present a positioning interface, and the positioning interface presents information for guiding a user to execute touch positioning operation.
Wherein the target state is typically a triggered state.
The target application is generally an application for implementing positioning of a touch position of the 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 the user to perform touch positioning operations. As an example, information may be presented on the positioning interface for guiding the user to trace on the outline of the projection area. At this time, the touch positioning operation is an operation of tracing on the outline of the projection area.
Optionally, the positioning interface presents information for guiding the user to perform touch positioning operation, including: the positioning interface presents a plurality of contour positioning points and information for guiding a user to click 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 is typically presented with 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 locating point is typically a point for determining the position of the projection area. At this time, the touch positioning operation may be: clicking the contour locating point of the projection area.
As an example, the contour anchor points may be four vertices of the projection area.
As another example, the contour anchor point may be four vertices of the projection area plus a center point of the projection area.
Fig. 5 is a schematic distribution diagram of contour positioning points according to an embodiment of the present application. As shown in fig. 5, P0-P8 are contour anchor points. P0-P8 are distributed over a projection area 502, the projection area 502 being located on an electronic whiteboard 501. Wherein P0 is the center point of the projection area, P1-P4 are the vertices of the projection area, and P5-P8 are the midpoints of the four sides of the projection area.
Step 303, based on the control instruction, receiving a touch positioning operation performed by the user based on the positioning interface, so as to implement touch positioning.
Here, after the electronic whiteboard issues a control instruction to the target application, the electronic whiteboard may be projected with a positioning interface. Thus, the user can execute touch positioning operation on the electronic whiteboard based on the guiding information presented by the positioning interface so as to realize touch positioning.
Optionally, based on the control instruction, receiving a touch positioning operation performed by the user based on the positioning interface to implement touch positioning, including: and selecting a contour locating point from a plurality of contour locating points presented by a locating interface, and executing information prompt operation on the selected contour locating point. And responding to the detection that the user clicks the contour locating point, acquiring coordinate values of the contour locating point, selecting an unselected contour locating point from a plurality of contour locating points, and continuing to execute information prompt operation until each contour locating point is clicked. And determining coordinate values of each touch point on the electronic whiteboard according to the coordinate values of the plurality of contour locating points, so as to realize touch location.
The information prompting operation generally refers to an operation of displaying information for prompting a user to click on a contour locating point beside the contour locating point.
Here, each contour locating point can be displayed on the locating interface, and a prompt message for prompting the user to click on the contour locating point is displayed by flashing beside one contour locating point. After the user clicks the contour locating point, the locating interface flashes beside other contour locating points to display the prompt information for prompting the user to click the contour locating point until all the contour locating points are clicked. Thus, the electronic whiteboard can acquire the position of each contour locating point on the electronic whiteboard and the coordinate value under the target coordinate system. 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 position of the same contour locating point in the electronic whiteboard and the coordinate value under the target coordinate system. Therefore, the coordinate value of each touch point on the electronic whiteboard under the target coordinate system can be calculated based on the mapping relation. Thereby realizing the positioning of the touch position on the electronic whiteboard.
It should be noted that, the electronic whiteboard may also only acquire the position of the contour locating point clicked by the user on the electronic whiteboard, and then send the acquired position of the contour locating point on the electronic whiteboard to the target application. So that the target application obtains the mapping relation between the coordinate system of the electronic whiteboard and the target coordinate system based on the position of the same contour locating point in the electronic whiteboard and the coordinate value under the target coordinate system. Therefore, the coordinate value of each touch point on the electronic whiteboard under the target coordinate system can be calculated based on the mapping relation. Thereby realizing the positioning of the touch position on the electronic whiteboard.
According to the method provided by the embodiment, the state of the target key is detected, so that when the key state is the target state, the target application is controlled to present a positioning interface. The user can conveniently and rapidly open the positioning interface by pressing the target key, so that touch positioning operation is performed based on the guiding information of the positioning interface to realize touch positioning. The method is beneficial to improving the efficiency of positioning the touch position on the electronic whiteboard.
In an optional implementation manner of each embodiment of the present application, the sending a control instruction to the target application includes:
And sending a control instruction to the target application through a preset universal serial bus (Universal Serial Bus, USB) interface.
In the implementation manner, the terminal equipment where the target application is located is generally provided with the USB interface, so that the control instruction is sent to the target application through the USB interface, the implementation is easy, and the cost can be saved.

Here, the execution body may update the value of the parameter to the second preset value in time after sending the control instruction to the target application. Updating the value of the parameter for indicating the opening and closing state of the positioning interface in time is beneficial to realizing accurate control of the positioning interface of the target application.

The second preset value is used for indicating that the opening and closing state of the positioning interface is an opening state.
Here, when the key state of the target key is the target state and the positioning interface is currently in the on state, a control instruction for controlling the target application to close the positioning interface is sent to the target application, so that the positioning interface can be closed when the user presses the key again. The opening and closing of the positioning interface can be controlled through the hardware keys, the operation is convenient, the user can quickly open the positioning interface, and the efficiency of positioning the touch position on the electronic whiteboard is further improved. And helps to improve the user experience.
