A Distance Interaction Method Based on Pen

Abstract

This paper presents a new interactive way to solve the problem of human-computer interaction, with a pen as the media to achieve some operations. Firstly, this paper proposes a particle filter algorithm based on immune mechanism, and extracts the user pen operations by camera video. Then extract the line of pen's motor trend pen movement trend with the least square method and judge the legality of the pen operation and calculate the operation direction of the pen. Finally, we will gain mapping relation in the change in of machine interface.
