The UMTRI driving simulator family consists of six simulators used for research on in-vehicle devices (e.g., cellular phones, collision warnings displays), medical considerations (e.g., impairments due to alcohol and Alzheimer's disease, along with individual differences due to age and sex), steering system dynamics, and simulator design characteristics. The report describes the Driver Interface Research Simulator, a network of Macintosh computers that generate the road scene, instrument panel graphics, sound, and traffic. Decisions were made with an eye towards performance, flexibility, and ease of implementation. The solutions chosen were: 10Base-T Ethernet using Apple Talk protocol; distributed coordination; dead reckoning. Future directions of network development are also described. |
