Summary: | 碩士 === 元智大學 === 資訊工程學系 === 94 === With the increasing advancing of pervasive computer and information technology, human-computer interaction has become a major research and development topic. The goal of this study is to involve human-computer interaction for ubiquitous interactions so as to provide a friendly service for users and to alleviate the burden of typing in keyboard and writing in tablet. In other words, the proposed method tries to recognize hand gesture, which in turn to provide a comfortable, attentive, and reliable system for human-computer interface.
The proposed method consists of three phases: hand detection, fingertip tracing, and hand gesture recognition. In the stage of hand detection, skin-color information is used to detect the hand silhouette. In the stage of fingertip tracing, the edge detection and fingertip mask are involved to extract the fingertip trajectory. Finally, in the stage of hand gesture recognition, the fingertip trajectory vectors are extracted and matching strategy is adopted to achieve the goal of recognition. The effectiveness and practicability of the proposed method have been demonstrated by various experiments.
