Tierra Inhospita: exploring a virtual world with your face

Published: 15 June 2005 Publication History

Abstract

In this poster, we describe the application of advanced computer vision techniques to create a perceptual interface based on face detection, tracking and pose estimation."Tierra Inhospita" is a virtual 3D world, similar to a first-person game, controlled by means of the user's head. Using integral projections, faces are tracked in a fast and reliable way. Then, additional information is extracted from the projections to estimate 3D position and orientation of the face. Although not accurate in terms of 3D locations, these estimations accomplish their purposes of stability and responsiveness to user's gestures. Finally, these parameters are converted into movement in the virtual world.The proposed technique has been implemented and tested in a prototype, which is publicly available [1]. Our experiments have proved the viability of the method.
