Abstract

The embodiment of the present application discloses a touch control method and device for a touch all-in-one machine. The method includes: storing the coordinates of touch points that detect consecutive touch actions in a coordinate queue; if the touch point in the coordinate queue is detected The horizontal coordinates and / or the vertical coordinates have the same continuous change trend, and the change value exceeds the threshold value, then send a key instruction to the processor CPU, and the key instruction is used to instruct the display screen display content to execute in accordance with the horizontal coordinate and / or vertical coordinate change The corresponding operation of the trend. In this embodiment of the application, when the application displayed on the display screen is in the full-screen display state, the MCU in the lower computer switches to the keyboard mode, and the MCU converts the detected touch point coordinates into key instructions, which are executed by the CPU in the upper computer. The key commands the corresponding key response. Therefore, when the application displayed on the display screen is in a full-screen display state, the application program can be directly touch-controlled by swiping the screen, and the operation is simple.

Description

technical field [0001] The present application relates to the technical field of touch all-in-one machines, and in particular to a touch control method and device for touch all-in-one machines. Background technique [0002] The touch all-in-one machine is a human-computer interactive device that integrates touch technology and computer technology. It uses a touch screen instead of a traditional mouse or keyboard for information input, making human-computer interaction easier, and is widely used in conferences and teaching. and other places. [0003] figure 1 It is a structural block diagram of a touch all-in-one machine in the prior art, such as figure 1 As shown, the touch all-in-one computer includes an upper computer and a lower computer. Wherein, the upper computer and the lower computer can be set integrally or separately, the upper computer includes a processor (Central Processing Unit, CPU), and the lower computer includes a microcontroller unit (Microcontroller Un...
