触觉二维图像识别的认知机制

Abstract

The two-dimension tactile image is the main approach of translating visual information into haptic information. It plays an important role in helping visually impaired people perceive the external world. The recognition of haptic two-dimension image is considered to be based on the "visual translation" process where the haptic input is translated into the visual image. This process is influenced by the graphic geometric feature, perspective, visual experience, capability of visual representation, the process of tactile exploration, training and age. Exploration of the cognitive neural mechanism of two-dimension images haptic recognition is significant for improving the design and usability of two-dimension tactile images.
