Super-Feet: A Wireless Hand-free Navigation System for Virtual Environments

Navigation is a fundamental task in virtual environments. Some of the metaphors that are used to determine where users want to be placed at each moment are based on physical locomotion. Usually, these techniques require the use of several sensors and complex algorithms. In this paper, we present Super-Feet, a wireless navigation system controlled by natural movements without requiring invasive methods or devices. It uses a low-cost infra-red system to detect the instantaneous position of both feet and this information is translated into a walking and rotation velocity in the environment. Preliminary results show that Super-Feet navigation is more accurate but slower than joypad based navigation systems. © Springer-Verlag Berlin Heidelberg 2007.
