Combining a pico projector with a webcam, a laser pointer, and image processing software enables full control of any computing system via the laser pointer. Pointer on/off actions, motion patterns (e.g., dwell, repetitive visit, circles, etc.) and more can all be mapped to events which generate standard mouse or keyboard events, or user ...
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 .
User's guide for a Dulcitone keyboard. A user guide, also commonly known as a user manual, is intended to assist users in using a particular product, service or application. It is usually written by a technician, product developer, or a company's customer service staff. Most user guides contain both a written guide and associated images.
Video projectors can have a mechanism similar to local backlight dimming to achieve higher contrast ratios by using 6 DLP chips: 3 for display, and 3 for local dimming. [11] [12] A few camcorders have a built-in projector suitable to make a small projection; a few more powerful "pico projectors" are pocket-sized, and many projectors are portable.
Pico projectors, near-eye and head-mounted displays [ edit ] Whilst initially developed for large-screen projectors, LCoS displays have found a consumer niche in the area of pico-projectors , where their small size and low power consumption are well-matched to the constraints of such devices.
The technology goes back to 1973 with Harvey C. Nathanson's (inventor of MEMS c. 1965) use of millions of microscopically small moving mirrors to create a video display of the type now found in digital projectors. [1] The project at Texas Instrument's began as the deformable mirror device in 1977 using micromechanical analog light modulators.
Laser color television (laser TV), or laser color video display, is a type of television that utilizes two or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display.
