3D interactive display with embedded optical sensor was one of the interactive systems. Based on optical sensor based system, traditional algorithm which used LED light source as a 3D interactive device can only obtain three dimensional information(x, y and z) of LED. Furthermore, the traditional algorithm is difficult to calculate correct three dimensional information of LED when LED has inclined direction or has a rotation angle. Therefore, T mark algorithm was proposed to 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. Finally, the proposed algorithm was demonstrated to interact with auto‐stereoscopic images on 4‐inch panel in real time process.
