Visual Monitoring with Spatially versus Temporally Distributed Displays
通过三个实验比较了空间分布与时间分布（RAP COM）显示器在视觉监控任务中的表现，发现RAP COM显示器响应更快但错误率更高，可能不适合实际系统应用。
Recent research has examined performance levels using rapid communication (RAP COM) visual displays. We extended this research in three experiments using a task in which subjects monitored visual displays representing dynamically varying system parameters and responded whenever an indicator value went beyond a specified range. In the spatial condition the indicator values were simultaneously presented in different locations on the CRT; in the RAP COM condition each indicator was presented in successive frames in a central location on the CRT. Results indicated that RAP COM displays yielded shorter response latencies than did spatial displays and that RAP COM displays produced significantly higher error rates. The same pattern was obtained with different stimulus-response mappings and across a range of practice levels. These findings indicate that RAP COM displays may not increase overall system performance, given the elevated error rates obtained with these displays. These error rate data indicate that it may not be possible to implement RAP COM displays in real-world systems. Possible reasons for the high error rate obtained with the RAP COM displays are discussed.
