Texas Instruments DLP exhibited a variety of 3D-ready projectors using the company’s single-projector technology. 3D-ready DLP projectors from BenQ, InFocus, Mitsubishi, Optoma, ViewSonic, and Vivitek are currently available, and Acer, Dell, NEC, and Sharp will be shipping 3D-ready projectors for the education market soon. TI DLP also is working with content providers to deliver interactive 3D content for teaching various topics ranging from science to art. JTM Concepts recently conducted independent studies in the state of Illinois to compare the results of grade school classes taught with a 3D curriculum versus standard teaching methods. The research, supported by state funding, showed that students taught using one of JTM’s Classroom3 3D simulations had an average test-score increase of up to 35 percent, compared with a 9.8-percent average increase from traditional teaching methods.
