Abstract
A tactile human-user interface system provides a refreshable tactile display that communicates text and images. The system includes a processor and a set of transducers. The processor receives text and/or image input and defeatures any images in the input to produce a simplified image. The processor translates the input into tactile form, which it converts into a set of electrical signals associated with a set of pixels of a display. Each transducer of the set of transducers corresponds to a respective pixel of the set of pixels. The set of transducers receive, from the processor, the set of electrical signals. The set of transducers generates, in response to the set of electrical signals, tactile outputs, detectable by a finger of a human user, at locations corresponding to the set of pixels.
