Virtual Retinal Display
Virtual Retinal Display
Seminar Report 2004
Abstract
The Virtual Retinal Display (VRD) is a personal display device under development at the University of Washington 's Human Interface Technology Laboratory in Seattle, Washington USA. The VRD scans light directly onto the viewer 's retina. The viewer perceives a wide field of view image. Because the VRD scans light directly on the retina, the VRD is not a screen based technology. The VRD was invented at the University of Washington in the Human Interface Technology Lab (HIT) in 1991. The development began in November 1993. The aim was to produce a full color, wide field-of-view, high resolution, high brightness, low cost virtual display. Microvision Inc. has the exclusive license to commercialize the VRD technology. This technology has many potential applications, from head-mounted displays (HMDs) for military/aerospace applications to medical society. The VRD projects a modulated beam of light (from an electronic source) directly onto the retina of the eye producing a rasterized image. The viewer has the illusion of seeing the source image as if he/she stands two feet away in front of a 14-inch monitor. In reality, the image is on the retina of its eye and not on a screen. The quality of the image he/she sees is excellent with stereo view, full color, wide field of view, no flickering characteristics.

Seminar Report 2004
Introduction
Our window into the digital universe has long been a glowing screen perched on a desk. It 's called a computer monitor, and as you stare at it, light is focused into a dimesized image on the retina at the back of your eyeball. The retina converts the light into signals that percolate into your brain via the optic nerve. Here 's a better way to connect with that universe: eliminate that bulky, powerhungry monitor altogether by painting the images themselves directly onto your retina. To do so,
