Virtual Retina Display

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.

Digital Scent Technology

  Technology has till date be able to use our sense of site and sound quite successfully in bringing virtual reality and nearer to reality. Consequently you have realistic-looking games, and graphic cards that are capable of rendering them; mice that let you experience the terrain you are traversing, whether in an application, on the internet, or on a CD-ROM; and sound and music, thanks to MP3 and the like, which bring alive your experience in the virtual world. Virtual reality has, since the onset several decades ago, been dominated by visual stimuli, with tactile and auditory information research and added to the sense in the latter years.

Space Mouse

Every day of your computing life, you reach out for the mouse whenever you want to move the cursor or activate something. The mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately. An ordinary mouse detects motion in the X and Y plane and acts as a two dimensional controller. It is not well suited for people to use in a 3D graphics environment.
