A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens , but some newer types of projectors can project the image directly, by using lasers .
A sensor or camera in the projector picks up finger movements. Software converts the coordinates to identify actions or characters. [1] Some devices project a second (invisible infrared) beam above the virtual keyboard. The user's finger makes a keystroke on the virtual keyboard. This breaks the infrared beam and reflects light back to the ...
Handheld projectors, in particular projector phones, could offer new possibilities for mobile gaming, as demonstrated by the adaptation of the PlayStation 3 game LittleBigPlanet. Players can sketch a world on a sheet of paper or use an existing physical configuration of objects and let the physics engine simulate physical procedures in this ...
In contrast, a modern LCD or DLP projector often uses an Ultra-high-performance lamp which has a higher luminous efficacy and lasts for thousands of hours. [5] A drawback of that technology is the warm up time required for such lamps. Older overhead projectors used a tubular quartz bulb which was mounted above a bowl-shaped polished reflector.

By contrast, a digital cinema playback system—including server, media block, and projector—can cost two to three times as much, [70] and would have a greater risk of component failure and obsolescence. (In Britain the cost of an entry-level projector including server, installation, etc., would be £31,000 [$50,000].)
Quite often these spools will be located some way from the projector and the film path may be over rollers along the ceiling of the projection room and surrounds. The lenses of the projector can be automatically rotated in front of the projector light aperture to accommodate the correct lens for a given format. The picture to the right shows a ...
