Abstract:

Gestures are a natural and intuitive interpersonal communication model,and vision-based gesture recognition is an indispensable and key technology which can achieve a new generation of human-computer interaction.This article combines gesture recognition and the control of slideshow system with four dynamic gestures defined.Arresting gesture moving centroid overcomes the shortcoming of complicated gestures.A convenient classroom interaction gesture recognition system is achieved with FPGA as the main operating platform combined with MATLAB simulation.

Key words: human-computer interaction;gesture recognition;FPGA;timeliness;classroom interaction
