摘要:
An interactive braille display system includes a processor and a display unit in electronic communication with the processor. The display unit includes a braille cell unit and an interactive unit in physical contact with the braille cell unit. The interactive unit includes a surface layer for displaying braille information and sensing tactile contact by a user. The interactive unit also includes a subsurface layer in physical communication with the surface layer, the subsurface layer including electrodes for detecting a capacitance change caused by the tactile contact by the user. The capacitance change corresponds to a position of the tactile contact by the user.
