Paper Abstract

This paper describes recent advances in the field of autostereoscopic display development and introduces an appropriate integration of a novel user interaction technology. Beside technical aspects of the developed autostereoscopic display technology, the paper includes topics of our video-based interaction technique and introduces promising applications of autostereoscopic single user displays. Based on results of the European ATTEST project, the Fraunhofer Institute for Telecommunications (HHI) has developed the Free2C 3D display technology, which provides free positioning of a single viewer. The optics of the Free2C displays is designed such that extremely low crosstalk, excellent color reproduction and high brightness are achieved. Simple and intuitive interaction is a requirement for multi-modal 3D displays. For this reason, a novel technology has been integrated into the control console that can recognize a persons' hand and its gestures. Displayed 3D objects floating in front of the screen can be rotated by simple gestures and virtual buttons can be pressed by pointing at them (virtual 3D touch screen). Several applications are currently used by customers and have been presented at trade shows, exhibitions and showrooms. Feasible applications are based on computer generated content, live video created by stereoscopic cameras and films stored on hard disk. Immersive media presentations are one promising application for attractive stereoscopic representations. The Free2C Kiosk and the 3D Media Center combine a high-resolution autostereoscopic 3D display with a video-based hand-gesture recognition device for direct manipulation of virtual 3D objects floating in front of the screen.
