However, little research has been done on the 3D interactive systems applied on portable devices. For satisfying the requests of portable devices, 3D interactive systems combined embedded optical sensor and additional light sources will be a better solution. In this structure, we propose three kinds of 3D interactive systems for different requirements. T Mark System uses light source pasted with T mark to detect the 3D positions (X, Y, and Z)、rotation angle (θ) and tilt angle (φ) of single user. For detecting more complex actions, two multi-interactive systems will be proposed. Color Filter Based uses visible light sources and color filters to distinguish different light sources and calculating the 3D positions of each light source. This system is still workable when the projections of light sources are seriously overlapping. However, the visible light sources will reduce the image quality of display. For solving this issue, Multi-Mark Based replaces the visible light sources by IR light sources pasted with different marks. After analyzing the projections of these light sources, the 3D positions of each light source can be obtained. However, Multi-Mark Based cannot detect certain overlapping conditions perfectly. This system is suitable for multi-user. Shieh, Han-Ping D. Huang, Yi-Pai 謝漢萍 黃乙白 2011 學位論文 ; thesis 69 zh-TW |
