Abstract

A dynamic projected user interface includes a light source for generating a light beam and a spatial light modulator for receiving and dynamically modulating the light beam to create a plurality of display images that are respectively projected onto a plurality of keys in a keyboard. An optical arrangement is disposed in an optical path between the light source and the spatial light modulator for conveying the light beam from the light source to the spatial light modulator.

Description

Background technique [0001] The functional usefulness of a computing system is largely determined by the manner in which the computing system outputs information to a user and allows user input to the computing system. A user interface generally becomes more useful and powerful when it is specifically tailored for a particular task, application, program, or other context of the operating system. Probably the most widespread computing system input device is the keyboard, which provides alphabetic, numeric, and other orthographic keys as well as a set of function keys that generally have wide utility in various computing system contexts. However, the functions assigned to these function keys typically depend on the computing context and are often assigned very different functions with different contexts. Furthermore, orthographic keys are often assigned non-orthographic functions, or are required to be used often only by pressing combinations of keys simultaneously, such as by ...
