视线跟踪技术在人机交互中的研究

Research on Visual Trace Technology in Human-Computer Interaction

人们在观察外部世界时眼睛总是与其它人体活动自然协调地工作,并且眼动所需的认知负荷很低,人眼的注视包含着当前的任务状况以及人的内部状态等信息,因此眼注视是一种非常好的能使人机对话变得简便、自然的候选输入通道。本文介绍了视线跟踪的基本原理、方法,对视线跟踪作为人机交互通道所具有的特点进行了讨论,并指出了其在人机交互领域中的应用及前景。

When people observe the outside world,their eyes always coordinate naturally with the other physical movements with very low cognitive load.The gaze of human eyes contains much information such as the condition of the present task and the inner state of humans,so the gaze of human eyes is a superior alternative input channel which enables the dialogue between humans and computers to be simpler and more natural.The essay introduces the basic principles and methods of the visual trace,dicusses the characteristics of the visual trace as the channel of Human-Computer Interaction,and points out the application as well as the prospect of the technology in the field of Human-Computer Interaction.
