Abstract

Head- and eye-tracked 3D display systems provide glass-free 3D experience while offering a free movement of the observer within the tracking range. In either autostereoscopic or holographic 3D displays, eye-tracking systems are used for following left and right eye position of the observer in real time. Knowing the exact eye positions, the 3D display system provides the proper perspective views to the display user. For autostereoscopic displays these are left and right 2D stereo sub-images, whereas for holographic displays these are left and right holographic 3D reconstruction, respectively. For angular separation of the particular views, special optical light-steering devices are employed. Thus, a fast eye tracking combined with smooth light steering ensures a complete 3D visualization for the user at any time over a wide viewing range.
