Classroom Demonstration Application Based On Leap Motion

Classroom demonstration is the main part of the teaching process. To a large extent, the classroom demonstration technology defines classroom teaching form. At present, the means of human-computer interaction Shanghai schools classroom demonstration is the mouse control, laser pen and touch screen. In the conditions of use, the price, the required training time, maintenance and so can not meet the demand of interactive classroom environment in primary and middle schools. School informatization development needs of a convenient maintenance, easy classroom interactive system of promotion, to enrich the classroom demonstration program.Aiming at the application scene of man-machine interactive classroom presentations of gesture recognition technology, this paper discusses the realization of classroom demo system based on LeapMotion. Main research work includes the following. (1) for classroom demonstration status and needs of primary and secondary schools were investigated and analyzed. (2) research and introduces the principle of non-contact gesture recognition technology, using Leap Motion to obtain the hands, fingers information. (3) the classroom presentation of non touch features, the function of LeapMotion, defines a set of easy to use, easy to understand hand gestures, so that users can easily interact with gestures and software. (4) research and design a classroom demonstration man-machine interaction system of the gesture recognition. (5) using Eclipse as the development tool, design and develop a set of corresponding gesture recognizer based on LeapMotion, the system has a good stability, real-time and high accuracy. For classroom demonstration school patterns of abundance and improvement, this paper has certain reference value.
