Abstract

Abstract: Considering properties of touch interaction of intelligent terminals, a fast generating algorithm of interest roaming path based on freehand sketch was proposed and applied in the 3D mobile interactive system of virtual display. The self-adapting reduce method was adopted to optimize the feature points of sketch curve for addressing too much feature points in local. The piecewise curve fitting method was used to quickly generate smooth obstacle avoidance path for handling the case of sketch line over the obstacle, and the final roaming path was adjusted to approximate the freehand sketch as much as possible by error control. Experimental results show that the orientation, velocity and visual angle have changed naturally in whole process of virtual roaming along the generated interest roaming path with better performance in stability and real time.
