摘要
为帮助盲人或视觉障碍人通过触摸达到学习和感受的目的,设计了触觉图文图像显示系统。触觉图文信息主要来源于视觉图文,研究了视觉-触觉图文转换以及与人体的触觉特性相适应的触觉数据结构,介绍了面向图文图像触觉显示系统。结果表明该系统可以实现2D、3D灰度图像的再现,使用者可以真实地识别图文图像信息。此外,扩大了面向图文信息的触觉显示的应用领域。
It designs a tactile display system of graphical information, which helps a visually impaired user or blind user study and sense from the image tactile display. The most tactile image information comes from vision image. It discusses the vision - tactile convert, puts forward the tactile data structure which is adapted to the tactile sense of mankind, and introduces a new tactile system faced to text and graphical information. This system enables realize the display of 2D/3D image; it allows users to tactually recognize graphical information situated in the real world. At furthermore, it also opens the door to a wide range of applications which could be based graphical information tactile display.
