Walking simulation in a virtual town by using a Web camera

Abstract

This paper describes a city walking simulation method for by using a Web camera. An operator, who has markers on his/her knees, makes stepping motion at the same spot in front of a Web camera. The stepping motion is input to a PC through the web camera and the markers are traced in real time, then the stepping speed is calculated. Simultaneously direction of the operator's face is recognized to change the viewing direction. Moreover, specified foot motion directs the direction change of walking. Thus, real-time walking simulation has been achieved by combining with a CG generated virtual town.
