摘要: | 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. |
