Paper Abstract

The tracking of observer's eyes positions in front of a 3D display is necessary to ensure a correct autostereoscopic view of position-dependent 3D images. We present a new real- time eye tracking system using two commercially available web cams detecting the observer's eyes in x, y and z direction. The entire system can be installed on a standard PC together with an autostereoscopic display. In a first process eye-candidates are detected by implementation of a fast pattern recognition. The additional use of the color information of the web cams provides more useful information on finding eye-candidates. In a second step from eye-pairs that are nearest to a monitor world-coordinates are calculated. Signal transmission and processing delays are compensated by an adaptive predictor. Thus the entire system is cheaper, smaller in size and it can be installed on a standard PC. In addition the tracking software can also support other applications, e.g. to set up a teleconference system in conjunction with an autostereoscopic monitor.
