| 中文摘要 | 本文提出采用结构光源充分表达用户手部运动的想法,设计了结构光源和识别软件,从光点序列中提取出光点运动轨迹和用户手势的旋转信息,搜索光点位置序列的平坦区段锁定目标位置,将旋转手势解释成交互原语以扩充激光笔的交互语义.最后的性能评估结果表明,结构光源在丰富交互语义和加速目标选择方面都有着较大的改进.; In this paper,structured laser pointer(SLP)is proposed to sufficiently express the movement of user’s hand.Firstly,the SLP is designed as input device,and then the corresponding signal processing application is programmed to filtrate the sequence of laser spots,and extract the trajectory of the laser spots and user gesture from the sequence.And the laser trajectory and user gesture are translated into original interactive language to increase the semantic interaction.Using a SLP can acquire a target quickly because the dwell of laser spots are not required.Instead,we search the plain section in the sequence of laser spots to quickly and accurately select the target that people want to point to.Finally,according to Fitts’ law,a user study is designed that requires participants to achieve several tasks.It proved that SLP performs much better than traditional laser pen in speed,and using SLP can also express more semantic interaction.; 国家863高新技术研究发展计划(No.2006AA01Z198) |
