Redirected walking (RDW) gives users the ability to explore a virtual world by walking in a confined physical space. It inconspicuously guides them on a physical path that might differ from the path they perceive in the virtual world. Exploiting three motion illusions-the change-blindness illusion, the four-stroke motion illusion, and the motion-without-movement illusion-can increase RDW's effectiveness.
