摘　　要：震动技术信息表达是一种有效的人机交互模式和信息传递方式,并作为信息传递的重要通道用于盲人导航/路径诱导辅具领域,弥补了在特定条件下声音的缺点与不足。针对盲人具有敏锐于常人的触觉资源和对路径诱导环境特定的感知,综合应用GPS、GIS和Haptic(震动)等技术,开发研制一种盲人路径诱导新模式。在此基础上,进一步探讨该模式向盲人提供路口等关键节点和偏离规划路径多种情况下的差异性震动。具有抗噪声干扰、反馈及时和接收效率高等优势,具有很高的应用前景。Haptic （vibration） technical information expression is an effective human-computer interaction mode and information transfer mode. It makes up the shortcomings of sound under certain conditions and is an important channel for information transfer in the field of blind navigation^route guidance. The blind have sharper-than-average tactile resources and specific perception on route guidance environment, in light of this, in our study we develop a new mode of route guidance for the blind based on the integrated application of GPS, GIS and haptic （vibration） technology. On that basis, we further discuss that this mode provides the vibrations with difference to the blind under a variety of circumstances： the key nodes at intersections, and the deviation from the planned path, etc. It has the predominance in noise interference resistance, in-time feedback and high reception efficiency, etc. , and has very good application prospects.
