可穿戴人机交互技术是普适计算的组成部分,提供了一种无处不在的计算和人机交互体验,当前可分为基于视觉的人机交互技术和无视觉人机交互技术.本文结合无视觉交互技术的概念与发展,从交互技术和交互模型等几个方面系统阐述了当前无视觉交互技术的核心理论和技术,分析了触控技术、触听觉交互技术、基于手势的交互技术几种交互技术的特点并指出其所存在的缺陷,为解决在无视觉情况下的移动与可穿戴设备的交互界面问题的研究提供了理论依据和导向. Wearable human-computer interaction technology is an integral part of pervasive computing, providing a ubiquitous computing and human-computer interaction experience, and can be divided into visual-based human-computer interaction technology and non-visual human-computer interaction technology currently. The concept and development of non-visual interaction technology, the core theory and technology of non-visual interaction technology are expatiated systematically from the aspects of interaction technology and interaction model. The key technologies of touch technology, touch-auditory interaction technology, gesture-based interaction technology This paper provides the theoretical basis and guidance for the research on the interaction between mobile and wearable devices in the absence of vision.
