Electronic Devices: How Elumens Vision Station Works

Software integrates images of objects and events from 5 cameras with special lenses at various angles, for projection with field similar to human eyes.

Visual display has traditionally limited computer use. The shape and size of a computer screen is inappropriate for what the eye can see in real life. The field of view is a particularly limiting factor. The computer screen does not allow a viewer to see peripheral movement, though this is a normal human ability. The Elumens Vision Station is a significant advance in improving visual aspects of digital data. This device increases the field of vision on all four sides, left and right as well as above and below. Such a facility matters when a computer simulates a real-life event.

The Elumens Vision Station is a blend of advanced optics and sophisticated software. The system uses a special lens that has pixels distributed evenly all over its surface. It is able to capture images that have even brightness and clarity. This reduces if not eliminates distortion. The lens remains in focus at all depths. Four cameras at right angles on either side, and one each above and below a central camera, take photographs of objects and events from a series of angles. Proprietary software combines images from all the cameras to produce a 3-D effect that a person can enjoy without any special headgear. The 3-D images may be real or may be generated by special software. Other 3-D systems can also feed inputs for projection through the Elumens Vision Station.

The lens, camera positions and integration software form the proprietary part of the Elumens Vision Station technology. The system uses a standard LCD projector, though one of high brightness and resolution. Images are projected on to a curved surface. The latter resembles a satellite dish. The curved surface can be large enough to serve between 1 and 45 people at a time. The image has a 180 by 135 degree field. The software can run on conventional computers and the equipment is portable and easy to set up and to operate. The system gives a feeling of reality as though one were in the midst of a simulated event. People can move their heads in a natural manner and see images on all sides almost as though in real life. You get a sense of motion and depth that no computer screen can provide. Normal peripheral vision picks up projected images rather than those of the real surroundings, so that viewers feel as though they are inside the projected environment. However, one does not lose all touch with reality, as it is also possible to see beyond the field of projection.



The Elumens Vision Station creates a visual experience based on computer data that closely matches the real experience of being in a particular environment. Its main application is training pilots, combatants and other professionals to face situations that they might encounter. Architects and automobile manufacturers can use it to visualize their designs and plans before construction or production starts. There are important potential applications in the field of medicine. It can also be used for entertainment and for any presentation, but remains expensive compared to conventional computer screens.
