58.4: DSHARP — A Wide Screen Multi‐Projector Display
Gary K. Starkweather · SID Symposium Digest of Technical Papers · 2003
Abstract This paper describes a projection system using DLP projectors and parabolic mirrors to provide a 90 degree curved screen with a 4 to 1 aspect ratio. This display is intended to provide an “immersive” experience for the user and facilitate a very large canvas on which to utilize multiple applications or single ones requiring a large screen. The resulting display has a 3072 × 768 pixel display area. Furthermore, this display and replicas are being used to better understand how users interact with large, immersive displays. Currently, there are four units in use at Microsoft for various business and scientific purposes.
