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.
Claims20
A user interface device, comprising:
- a keypad having a plurality of actuable keys;
- at least one light source for generating a light beam;
- a spatial light modulator for receiving and dynamically modulating the light beam to create a plurality of display images that are respectively projected onto the plurality of keys;
- and
- an optical arrangement 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.
A medium comprising instructions executable by a computing system, wherein the instructions configure the computing system to:
- project a light beam;
- collimate the light beam;
- and
- spatially modulate the light beam to create a plurality of display images that are respectively projected onto a user-input receiving surface such that the plurality of display image represent a first set of input controls when a computing device is in a first operating context and second set of input controls when the computing device is in a second operating context.
