Description
Technical Field
The application relates to the technical field of touch control integrated machines, in particular to a touch control method and device of a touch control integrated machine.
Background
The touch control integrated machine is man-machine interactive equipment integrating a touch control technology and a computer technology, and adopts a touch screen to replace a traditional mouse or a keyboard for information input, so that man-machine interaction is simpler, and the touch control integrated machine is widely applied to places such as conferences, teaching and the like.
Fig. 1 is a structural block diagram of a touch all-in-one machine in the prior art, and as shown in fig. 1, the touch all-in-one machine includes an upper computer and a lower computer. The upper computer and the lower computer can be integrally arranged and can be separately arranged, the upper computer comprises a processor (Central Processing Unit, CPU), and the lower computer comprises a Micro Control Unit (MCU), a display screen and a touch screen. The CPU of the upper computer is in communication connection with the MCU of the lower computer, and in the lower computer, the MCU is in communication connection with the display screen and the touch screen respectively. When the display screen is used, a user can install a corresponding application program on the upper computer according to the requirements of the user, the CPU transmits the picture information of the application program to the MCU, and the MCU controls the display screen to display the corresponding picture. Meanwhile, the MCU detects the coordinates of the touch points on the touch screen according to a preset time interval, sends the detected coordinates of the touch points to the CPU, and the CPU executes corresponding touch response. For example, when the touch point coordinates are (x1, y1), the CPU performs a touch response of a click at coordinates (x1, y 1).
The screen of the application program generally has two display states on the display screen: a full screen display state and a non-full screen display state. When the screen of the application program is in a non-full screen display state, a touch control area is usually set on the display screen, and a corresponding instruction identifier (for example, a previous page or a next page, etc.) is marked in the touch control area, so that a user can realize touch operation of the application program by clicking the corresponding touch control area. Although the method can facilitate the operation of the user on the application program, the picture display effect is poor due to the low occupancy rate of the picture on the display screen and the interference of the touch control area on the display screen. Therefore, when using the touch-control all-in-one machine, the user usually switches the screen of the application program to a full-screen display state.
When the screen of the application is in a full-screen display state, the touch control area is usually hidden or deleted. Because the touch control area is not displayed on the display screen, the user can only call out the hidden touch control area or quit the full-screen display state by long pressing the touch screen, and then touch control operation is carried out on the application program, and the operation is complicated.

Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, 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.
Fig. 2 is a schematic view of a scene provided in an embodiment of the present application, and fig. 2 includes an upper computer 201 and a lower computer 202. The upper computer 201 includes a processor (CPU), and the lower computer 202 includes a Micro Controller Unit (MCU), a display screen, and a touch screen. When the PPT display screen is used, a user can install a corresponding application program, such as a PPT program, on the upper computer according to the requirement of the user, the CPU transmits PPT picture information to the MCU, and the MCU controls the display screen to display a corresponding PPT picture. Meanwhile, the MCU detects the coordinates of the touch points on the touch screen according to a preset time interval, sends the detected coordinates of the touch points to the CPU, and the CPU executes corresponding touch response. For example, when a user touches a previous touch control area, the MCU sends the detected touch point coordinates to the CPU, and the CPU executes a clicked touch response at the previous touch control area to realize page up operation of PPT.
It should be noted that fig. 2 is only a scene schematic diagram of the embodiment of the present application, and specific types and corresponding relationships of the upper computer 201 and the lower computer 202 in the diagram are not limited to the specific form disclosed in fig. 2. For example, the upper computer 201 and the lower computer 202 may be separately provided or may be integrally provided; the upper computer 201 and the lower computer 202 can be in communication connection through a signal line (for example, a USB line) and also can be in communication connection in a wireless mode; the upper computer 201 may be a PC, a notebook computer, a tablet computer, or the like, which is not specifically limited in this embodiment.
Taking the application scenario of PPT as an example. When a user uses the touch control all-in-one machine to perform PPT demonstration, the PPT screen is usually required to be switched to a full-screen display state in order to obtain a better screen display effect. However, since the touch control area is not displayed on the display screen in the full-screen display state, when a user needs to operate the PPT (for example, page up or page down), the user can only call out the hidden touch control area by pressing the touch screen for a long time or quit the full-screen display state, so as to perform a touch operation, which is cumbersome to operate.
In order to solve the above problem, an embodiment of the present application provides a touch control method for a touch all-in-one machine in a full-screen display state. Fig. 3 is a schematic flow chart of a touch control method in a full-screen display state of a touch all-in-one machine according to an embodiment of the present disclosure, where the method is applicable to the touch all-in-one machine shown in fig. 1 and 2, and as shown in fig. 3, the method mainly includes the following steps.
Step S301: touch point coordinates at which a coherent touch action is detected are stored in a coordinate queue.
When the touch screen works, the MCU in the lower computer detects the coordinates of the touch points on the touch screen according to a preset detection period. For example, when there is a touch operation of a user on the touch screen, the MCU may detect a touch position of the user on the touch screen, i.e., a touch point coordinate.
In the embodiment of the application, the MCU stores the touch point coordinates of the detected coherent touch action in a coordinate queue. The method specifically comprises the following steps: if the MCU detects a press operation action, storing coordinates corresponding to the press operation action in a coordinate queue, and sequentially storing the coordinates of touch points detected subsequently in the coordinate queue until a lift action is detected, and finishing the storage of the coordinates of the touch points. In other words, the touch point coordinates stored in the coordinate queue are the touch point coordinates detected between the press-down action and the lift-up action, and the coordinate queue is determined as the touch coordinates of the consecutive touch actions.
For example, when the user performs a screen sliding operation on the touch screen using a finger, the entire screen sliding operation may be composed of a start point, a sliding trajectory, and an end point. The starting point is the position where the user starts to contact the touch screen and is reflected in the lower computer as the position where the MCU detects the pressing operation action; the end point is the position where the user leaves the touch screen and reflects the position where the MCU detects the lifting operation action in the lower computer; the touch coordinates in the coordinate queue can reflect a sliding track of the sliding screen operation on the touch screen.
In this embodiment, the touch screen of the lower computer may be an infrared touch screen, a capacitive touch screen, a resistive touch screen, or an electromagnetic touch screen, which is not specifically limited in this application.
Step S302: and if the continuous variation trends of the transverse coordinates and/or the longitudinal coordinates of the touch points in the coordinate queue are consistent and the variation value exceeds a threshold value, sending a key instruction to a CPU (central processing unit).
In the embodiment of the application, when the MCU detects the lifting action, it indicates that the user has finished the screen sliding operation, and at this time, the button command received by the touch screen may be calculated according to the coordinates of the touch point in the coordinate queue. Specifically, if the continuous variation trends of the horizontal coordinates and/or the vertical coordinates of the touch points in the coordinate queue are consistent and the variation value exceeds a threshold value, a key instruction is sent to a processor CPU.
In order to realize the input of various key commands, different key commands can be configured for different sliding paths. Since the variation tendency of the coordinates of the touch point is different in different sliding paths, the key instruction intended to be input by the user can be determined based on the variation tendency of the lateral coordinates and/or the longitudinal coordinates of the touch point.
Based on the principle, in the embodiment of the application, the corresponding relation between the change trend of the horizontal coordinate and/or the vertical coordinate of the touch point and the key instruction is configured, and the key instruction received by the touch screen is determined according to the change trend of the horizontal coordinate and/or the vertical coordinate of the touch point in the coordinate queue. In addition, in order to avoid the touch screen from being triggered too sensitively, a certain threshold value can be set for the change value of the horizontal coordinate and/or the vertical coordinate of the touch point, and the key instruction received by the touch screen is determined only when the change value exceeds the threshold value. The trigger threshold value cannot be too large or too small, if the trigger threshold value is too large, the touch screen may be difficult to trigger, and if the trigger threshold value is too small, the touch screen may be sensitive to trigger, and misoperation is easily caused.
It can be understood that after the touch screen is determined to receive the key instruction, in order to facilitate the determination of the next key instruction, the touch point coordinates in the current coordinate queue need to be cleared, that is, the touch point coordinates stored in the coordinate queue are emptied.
Step S303: and the processor CPU executes corresponding operation according with the change trend of the horizontal coordinate and/or the vertical coordinate in the display content of the display screen.
And after receiving the key instruction, the CPU in the upper computer executes corresponding operation according with the change trend of the transverse coordinates and/or the longitudinal coordinates in the display content of the display screen. The display content of the display screen can be understood as an application displayed by the display screen, such as PPT, flash, and the like.
Taking an application scene of the PPT as an example, if the operation corresponding to the change trend of the transverse coordinate and/or the longitudinal coordinate is page-down, performing page-down operation on the PPT; if the operation corresponding to the change trend of the transverse coordinates and/or the longitudinal coordinates is page turning, performing page turning on the PPT; and if the operation corresponding to the change trend of the transverse coordinates and/or the longitudinal coordinates is the operation of withdrawing the pin at the previous step, the operation of withdrawing the previous step is executed on the PPT.
According to the technical scheme, in the embodiment of the application, when the application displayed by the display screen is in a full-screen display state, the MCU in the lower computer is switched to a keyboard mode, the touch screen is equivalent to a keyboard externally connected to the upper computer, the MCU is provided with a corresponding relation between the change trend of the coordinates of the touch points and the key instructions, the MCU converts the detected coordinates of the touch points into the key instructions according to the corresponding relation, and the CPU in the upper computer executes key responses corresponding to the key instructions. Therefore, when the application displayed on the display screen is in a full-screen display state, the touch control can be directly performed on the application program in a screen-sliding mode, and the operation is simple.
In addition, the key instruction determining process is realized in the lower computer in the technical scheme, and the upper computer only needs to receive the corresponding key instruction, so that the application program installed in the upper computer does not need to be adjusted, and the use is convenient.
In order to facilitate better understanding of the technical solution by those skilled in the art, the following description is provided with an exemplary correspondence relationship between a variation trend of coordinates of a touch point and a keystroke instruction in combination with an application scenario of a PPT. In fig. 4A-4C, the lower left corner of the touch screen (the orientation shown in the figure) is the origin of coordinates O.
In one possible implementation manner, the correspondence relationship between the variation trend of the horizontal coordinate and/or the vertical coordinate of the touch point and the key instruction is configured to: and if the horizontal coordinate of the touch point in the coordinate queue is continuously increased and/or the vertical coordinate is continuously decreased, and the change value exceeds a threshold value, determining that the key instruction received by the touch screen is page turning.
Two types of sliding screen operations are shown in FIG. 4A, respectively: a first slide operation 401 and a second slide operation 402. The first screen sliding operation 401 slides from the left side to the right side of the touch screen along the direction shown in the figure, and the horizontal coordinates of the touch points continuously increase progressively, so that when the first screen sliding operation 401 exists on the touch screen, the MCU of the lower computer generates a key instruction for turning down the page. The second sliding screen operation 402 slides from the upper side to the lower side of the touch screen along the direction shown in the figure, and the longitudinal coordinates of the touch points continuously decrease, so that when the second sliding screen operation 402 exists on the touch screen, the MCU of the lower computer generates a key instruction for turning down the page.
In another possible implementation manner, the correspondence relationship between the variation trend of the horizontal coordinate and/or the vertical coordinate of the touch point and the key instruction is configured to: and if the horizontal coordinate of the touch point in the coordinate queue is continuously decreased and/or the vertical coordinate is continuously increased, and the change value exceeds a threshold value, determining that the key instruction received by the touch screen is page turning.
Two types of sliding screen operations are shown in FIG. 4B, respectively: a third screen sliding operation 403 and a fourth screen sliding operation 404. The third sliding screen operation 403 slides from the right side to the left side of the touch screen along the direction shown in the figure, and the horizontal coordinate of the touch point continuously decreases, so that when the third sliding screen operation 403 exists on the touch screen, the MCU of the lower computer generates a key instruction for turning up the page.
The fourth sliding operation 404 slides from the lower side to the upper side of the touch screen along the direction shown in the figure, and the longitudinal coordinates of the touch points continuously increase in an increasing manner, so that when the fourth sliding operation 404 exists on the touch screen, the MCU of the lower computer generates a key instruction for turning up the page.
In another possible implementation manner, the correspondence relationship between the variation trend of the horizontal coordinate and/or the vertical coordinate of the touch point coordinate and the key instruction is configured to: and if the horizontal coordinate value of the touch point in the coordinate queue is detected to increase first and then decrease or decrease first and then increase, and/or the vertical coordinate value is detected to increase first and then decrease or decrease first and then increase, determining that the key instruction received by the touch screen is the operation of canceling the previous step.
Four types of sliding screen operations are shown in FIG. 4C, respectively: a fifth screen slide operation 405, a sixth screen slide operation 406, a seventh screen slide operation 407, and an eighth screen slide operation 408. The fifth screen sliding operation 405 slides from the left side to the right side of the touch screen along the direction shown in the figure, and then slides from the right side to the left side of the touch screen, and the horizontal coordinate value of the touch point increases gradually and then decreases gradually, so that when the fifth screen sliding operation 405 exists on the touch screen, the MCU of the lower computer generates a key instruction for canceling the previous operation.
The sixth screen sliding operation 406 slides from the right side to the left side of the touch screen along the direction shown in the figure, and then slides from the left side to the right side of the touch screen, and the horizontal coordinate value of the touch point is decreased gradually and then increased gradually, so that when the sixth screen sliding operation 406 exists on the touch screen, the MCU of the lower computer generates a key instruction for canceling the previous operation.
The seventh sliding operation 407 slides from the lower side to the upper side of the touch screen along the direction shown in the figure, and then slides from the upper side to the lower side of the touch screen, and the longitudinal coordinate value of the touch point increases gradually and then decreases gradually, so that when the seventh sliding operation 407 exists on the touch screen, the MCU of the lower computer generates a key instruction to cancel the previous operation.
The eighth screen sliding operation 408 slides from the upper side to the lower side of the touch screen along the direction shown in the figure, and then slides from the lower side to the upper side of the touch screen, and the longitudinal coordinate value of the touch point is decreased gradually and then increased gradually, so that when the eighth screen sliding operation 408 exists on the touch screen, the MCU of the lower computer generates a key instruction for canceling the previous operation.
By adopting the technical scheme, when the application displayed by the display screen is in a full-screen display state, the MCU in the lower computer is switched into a keyboard mode. However, when the application displayed on the display screen is in a non-full screen display state, the multi-touch mode of the MCU needs to be restored. Which mainly comprises the following steps.
Step S501: and judging whether the application currently displayed on the display screen is in a full-screen display state.
In the embodiment of the application, the display state of the application can be detected by the upper computer, and the display state of the application can be detected by the lower computer.
When the display state of the Application is detected by the upper computer, a specific Application needs to be installed in a system (e.g., a windows system) of the upper computer, and an Application Programming Interface (API) of the detection system is implemented by the Application, so as to determine the display state of the Application. When the display state of the application is detected by the lower computer, the MCU of the lower computer detects the application in the API of the upper computer in real time, judges whether a full-screen playing event exists or not and further determines the display state of the application.
Step S502: and if the application currently displayed on the display screen is in a full-screen display state, switching the MCU into a keyboard mode.
The keyboard mode referred to in this application is the control mode in the embodiment shown in fig. 3.
Step S503: and if the application currently displayed on the display screen is in a non-full screen display state, switching the MCU into a multi-point touch mode.
The multi-touch mode includes: and after detecting the touch point coordinate, sending the touch point coordinate to a CPU (Central processing Unit), wherein the touch point coordinate is used for indicating the display content of the display screen to execute corresponding operation conforming to the touch point coordinate.
For example, after receiving the touch point coordinates, the processor CPU executes a touch response of a click at a position corresponding to the touch point coordinates in the display content of the display screen.
By adopting the technical scheme, the MCU can be switched among different working modes according to the applied display state.
