Vision-based markerless gaming interface

vision-based markerless human machine interface for gam- ing applications is presented. The use of a single consumer grade camera results in a practical, reliable and cheap interaction method. The use of natural features in place of visual markers permits to avoid instrumenting the scene with optical markers while preserving real-time computation and accuracy. Two full-fledged videogames, built on top of this interface, are proposed in order to assess the intuitiveness, speed and user-perceived fun-factor of the proposed approach.
