一种红外多点触摸式双手交互技术

Infrared Multi-touch Two-handed Interaction Technology

随着人机交互技术由以往的以计算机为中心向以用户为中心发展,新型交互方式成为近年来研究的热点.双手交互作为一种自然的人机交互形式,不但符合人的认知习惯和行为特征,而且能提高计算机输入的带宽.本文研究了一种红外多点触摸的定位技术,识别并描述了双手触摸式交互动作,并建立了双手触摸式交互模型,实验证明了这种交互技术比传统的鼠标操作更加自然直观,大大提高了人机交互的效率.

With the development of HCI from ＂computer-centered＂ to ＂user-centered＂, many new-style interaction measures become the focus of recent researches. As a natural measure of HCI, two-handed interaction not only matches the habit of human cognition and behavior, but also improves the bandwidth of computer input. This paper does research on an infrared multitouch technology, gives the recognition and description of touch-based bimanual action, and sets up the touch-based two-handed interaction model. The result of the experiment shows that this kind of interaction is more natural and direct than traditional mouse-based interaction and the efficiency of HCI can be greatly improved.
