Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0035] refer to figure 1 , touch screen erasing gesture recognition system, including a microprocessor system, and a display system and a touch screen system connected with the microprocessor system, running drawing software 1 on the microprocessor system, and displaying the operation interface of the drawing software on the display system , the touch screen system is used to input operation instructions. Paint software has an erase command. The touch screen system scans 2 the touch points, and combines at least one touch point presented on the touch screen system as an operation command of an erasing instruction.

[0036] After the effective touch point combination 3 is scanned, the types of the touch point combination are distinguished, such as t...

Abstract

The invention relates to the computer field, in particular to a touch screen system. A touch screen erasing gesture recognition system comprises a micro-processor system, a display system and a touch screen system, wherein the display system and the touch screen system are connected with the micro-processor system. Drawing software operates on the micro-processor system, and an operation interface of the drawing software is displayed on the display system. The touch screen system is used for inputting an operation instruction. The drawing software is provided with an erasing instruction. A least one type of touch point combination presented on the touch screen system is regarded as an operating command of the erasing instruction. After the touch point combination is presented on the touch screen system, the micro-processor system starts to execute the erasing instruction and conduct erasing operation. According to the technical scheme of the touch screen erasing gesture recognition system, a traditional mode that the erasing operation is started by clicking a function key is no longer utilized, instead, the erasing operation is started through a touch gesture. Compared with the traditional mode, the operation is smoother, visual, convenient and fast.

Description

technical field [0001] The invention relates to the field of computers, in particular to a touch screen system. Background technique [0002] The appearance of touch screen has brought a lot of convenience for people's computer operation. Make the human-computer interaction more smooth, intuitive and convenient. [0003] But in the existing software that matches with the touch screen, more often the touch screen is positioned at the position that replaces the mouse. The technical advantages that the touch screen should have have not been fully utilized. [0004] Traditional electronic whiteboard software or drawing software has a function "eraser" to erase written notes on the screen. Generally speaking, it has three characteristics: 1. You need to click to select to enter the eraser mode; 2. After erasing, you must click the brush button to return to the writing mode. In addition to clearing and clearing the frame selection, the user is allowed Adjust the size of the er...
