Effectiveness of Coding Schemes in Rapid Communication Displays

An important issue in implementing Rapid Communication (RAPCOM) display technology is the manner in which information is coded within a given display sequence. This study compared performance on a search task for four single coding strategies as well as four redundant code combinations at five presentation rates. Results indicated significant differences in accuracy and reaction time for task performance using single and redundant codes at various frame durations. These findings helped to identify several potential coding formats that can be utilized in real-world settings.
