Touch user interface
open-in-new
<p>A touch user interface (TUI) is a computer-pointing technology based upon the sense of touch (<a href="/facts/Haptic_perception/HjD4T34m">haptics</a>). Whereas a <a href="/facts/Graphical_user_interface/wBlQFWDP">graphical user interface</a> (GUI) relies upon the sense of <a href="/facts/Visual_perception/g7Tfaq2l">sight</a>, a TUI enables not only the sense of touch to innervate and activate computer-based functions, it also allows the user, particularly those with <a href="/facts/Visual_impairment/sFuqKj3n">visual impairments</a>, an added level of interaction based upon tactile or <a href="/facts/Braille/SKtJVCmc">Braille</a> input. </p>
