Design of a Serial Communication Protocol and Bus Interface Chip for tactile Communications

摘要

Tactile communication requires rapid data transfer along a common bus. The developed communication protocol and application-specific interface chip enable precise control of multiple tactile transmitters (tactors) to convey information to military users. This extrapolation of the Tactile Situation Awareness System developed by the Naval Aerospace Medical Research Laboratory uses a serial data bus and individual interface chips to communicate commands with a minimum number of conductors. This thesis develops the communication protocol and the design of the Tactor Interface Chip (TIC). This work also includes a computer-driven tactile array controller and Parallel Port Data Modulator for TIC testing and demonstration.
