Touch User Interface

A touch user interface (TUI) is a computer-pointing technology based upon the sense of touch (Haptic-s). Whereas a graphical user interface (GUI) relies upon the sense of sight, the TUI enables not only the sense of touch to innervate and activate computer-based functions, it also allows the user, particularly those with visual impairments, an added level of interaction based upon tactile or Braille input.
