As display technologies prepare to welcome 3-D, the 21st-century classroom will soon bear little resemblance to anything students and teachers have ever seen. In this article, the author presents the latest innovations in the world of digital display technology. These include: (1) Touchlight, an interactive touch screen program that takes a normal…

This study suggests and identifies computer image generation (CIG) algorithms for visual simulation that improve the training effectiveness of CIG simulators and identifies areas of basic research in visual perception that are significant for improving CIG technology. The first phase of the project entailed observing three existing CIG simulators.…

The CHARGE computer terminal can provide graphics display for many applications in color, gray-level, 3-D, perspectives, and rapid updating. Perspective views can be generated from a three-dimensional coordinate system which changes to match actual physical descriptions. Image encoding and hardware design are described from a theoretical and…
