APA Dictionary of Psychology

in computing, several experimental types of user interface that enable on-screen data to be manipulated by direct physical means. Rather than appearing in graphical form, devices such as windows, icons, and handles are embodied as graspable, physical objects that can be used to access and manipulate data. The general goal of TUI development is to find solutions that bridge the gap between the digital world and the physical environment. Areas currently under investigation include (a) the transformation of architectural surfaces such as walls, doors, and tables into active interfaces with the digital world; (b) the creation of direct links between tangible objects, such as books, pictures, or models, and related digital information; and (c) the use of ambient media, such as light and sound, to convey background information to an operator. Compare graphical user interface; perceptual user interface.
