Laser pointer based constrained input scheme for educational game software framework

Abstract

In this paper, we present a new educational game interface using laser pointer based interaction with screen. Previous researches have focused on the display issue including stereoscopic and multimedia research, however they still use uneasy and un-natural interface based on keyboard/mouse or joystick along with PC for educational interaction. We implemented a laser based input device which composed of laser pointer and large active screen which tracks laser pointer. Laser based input device can give lots of flexibility on teaching staffs, and we propose an efficient character input configuration for the laser based large screen model for effective educational software framework. Experimental results show that we can easily input characters and numbers with more than 99 % of recognition rate. © 2011 Springer-Verlag.
