A camera free 3D interactive system for multi-user/multi-touch was proposed. By embedding the optical sensors in display pixels, the flat panel can sense images projected by infrared(IR) light. A light pen which can project T-mark IR image was utilized to determine the 5-axis (x, y, theta, phi) information of the user. Additionally, multiple T-marks with sequentially illuminating method can further identify multiusers even the marks are overlapped. Therefore, a 3-dimensional virtual touch display for 5-axis information with multi-user system can be achieved.

The traidational 3D interactive sysetm which uses CCD camera to capture image is difficult to operate on near range for mobile applications. Therefore, 3D interactive display with embedded optical sensor was proposed. Based on optical sensor based system, we proposed four different methods to support differenct functions. T mark algorithm can obtain 5-axis information (x, y, z,theta, and phi) of LED no matter where LED was vertical or inclined to panel and whatever it rotated. Sequential mark algorithm and color filter based algorithm can support mulit-user. Finally, bare finger touch system with sequential illuminator can achieve to interact with auto-stereoscopic images by bare finger. Furthermore, the proposed methods were verified on a 4-inch panel with embedded optical sensors.
