A vision substitution system for communicating audio and tactile representations of features of visual representations 10 includes processing lineal features into the form of apparently-moving audiotactile effects 6 of particular timbre (for example buzzing effects), and outputting said effects to audio and/or tactile displays 24 and 28; with additional effects 16 clarifying shape, slope, and location; and further distinct effects highlighting point-like features 8 and separate effects providing vision data 32 and 34; optionally providing facilities for blind people to create and access audiotactile images, data, graphs and waveforms; and to perceive features produced via computer vision processing, for example the shapes of areas of common properties, the nature of areas of movement, paths followed by moving entities, and symbolic paths representing identified entities such as people's faces. |
