Method for recognizing gesture on infrared induction type electronic whiteboard

Abstract

The invention provides a method for recognizing the gesture on an infrared induction type electronic whiteboard. The method comprises the following steps: classifying the first gesture recognition according to the number of touching objects; classifying the second gesture recognition according to the area of the touching objects, and further distinguishing the specific types of the gesture; and distinguishing the exact gesture according to the determined physical coordinates, and then, performing the functions of the gesture on the infrared induction type electronic whiteboard by whiteboard software. The gesture recognition mode of the invention is capable of recognizing most of the gestures on the infrared whiteboard so far, and the invention is characterized by the gesture recognition of the right key of a mouse; and the invention has the advantages of high recognition rate, accurate recognition and little error recognition.

Description

【Technical field】 [0001] The invention belongs to the field of information technology, and specifically refers to a method for recognizing gestures by an infrared induction electronic whiteboard. 【Background technique】 [0002] Interactive electronic whiteboard is also called "digital touch screen". Its function is that it can control the connected computer host through the touch panel. The projector projects the screen image of the computer onto the electronic whiteboard, and the user can control the computer by touching the surface of the electronic whiteboard. Running various application operating programs on the computer connected to the electronic whiteboard can directly realize various demonstration functions such as handwriting, graphics drawing, text input, file calling, deletion and copying, image saving, masking, video playback, and direct printing. Run specific applications, configure interactive electronic whiteboards and high-definition cameras, and realize re...

Problems solved by technology

[0005] With the continuous development of science and technology, shortcut operations can be completed through gesture recognition in the market, but the technology for realizing gesture recognition in the existing market is limited. The size of the capacitive sensing of the control panel is used to determine whether the touch object touches or leaves the touch panel to generate a timing combination to achieve different gesture operations. Another method is to confirm the touch and gesture according to the system sensing area. methods, these are difficult to meet the higher requirements of effectiveness and accuracy, leaving people with the disadvantage of not being able to enjoy more convenience
