Swierenga, Sarah J., Boff, Kenneth R. and Donovan, Rebecca S. (1991): Effectiveness of Coding Schemes in Rapid Communication Displays. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 1522-1526.

“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.”

Osgood, Sarah Swierenga, Boff, Kenneth R. and Donovan, Rebecca S. (1988): Rapid Communication Display Technology Efficiency in a Multi-Task Environment. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1395-1399.

“The present study examined the advantage of Rapid Communication (RAP-COM) Display Technology over conventional spatially arrayed displays in the context of secondary task demands. This research represents an early step in assessing the use of RAP-COM display techniques in multi-task environments. Eight subjects were instructed to respond to briefly presented visual stimuli, while concurrently performing an unstable tracking task at two levels of difficulty. Duration thresholds, obtained using a moment-to-moment adaptive tracking performance procedure, were collected for RAP-COM and spatially arrayed displays while RMS error scores were collected from the unstable tracking task performance. Information transfer rates for the RAP-COM technique were faster than for the spatially distributed array under both the single and dual task conditions. Regardless of secondary tracking task difficulty, subjects were able to maintain primary task performance levels on RAP-COM and spatial display tasks, although a decrement in tracking performance was seen.”
