基于手势的人机交互的研究

人机交互的本质是人的多维信息认知空间和计算机的信息表示空间之间的相互映射 。传统的用户界面范型遵循着一种基于命令的交互，交互的输入，输出是离散的事件流，交互中人的意图能自然、高效地表达，需要交互者较多的认知努力。基于手势的人机交互以手势表达交互意图，手势中含有大量的交互信息，同时又符合的人认知习惯。基于手势的交互具有非精确、多通道、连续等特点，能够实现人的认知空间和计算空间对间的平滑过渡，从而有效

Research on Gesture-based Human-Computer Interaction

The essence of human computer interaction (HCI) is the mutual mapping between the cognitive space of human and the computation space of computer. Traditional user interface paradigms conform to command based interaction, which the input and output is based on the stream of discrete events. The user can not naturally and efficiently express interactive intention and the interactive interface consumes much cognitive efforts. Gesture based interaction employs gestures to express interactive intention, which contains plenty of interactive information. It accords with the mental model of human and it is characterized by multi modal, continuous and inaccurate attributes, which can fulfill the smooth transformation from cognitive space to computation space. Consequently, it improves the bottleneck of the HCI. Pen based gesture interaction has the great significance of reality. The research for it will accelerate the development of the portable computers.
