Virtual touch 3D interactive system for autostereoscopic display with embedded optical sensor
2011
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,θ, and φ)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.
