触觉二维图像识别的认知机制

The cognitive mechanism of haptic recognition of two-dimension images

触觉二维图像可以辅助视觉受损人群,将视觉信息转化为触觉信息,从而感知外部世界。触觉二维图像的识别可能是通过触觉信息在大脑中进行"视觉转化"的方式而完成,并且会受到图形的几何特征、视角与透视、视觉经验、视觉表象能力、触觉探索过程、训练以及年龄的影响。探索触觉二维图像识别的认知神经机制,对于触觉二维图像设计的改进和可用性的提高,具有重要意义。

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.
