Human Performance Studies for Control of Multiple Remote Systems
Abstract
Many systems involving multiple remote sensors or machines require a single operator to control more than one device simultaneously. Interface design issues for operator support in such systems can be formidable, as the inherent task complexity creates significant opportunities for operator confusion and overload. A study was conducted to examine some of these issues, using a simulated industrial security environment as the applied setting. The operator task was to designate the number and location of intruders in a simulated building, using video information from remote sensor platforms. The experiment manipulated the number of displays which had to be monitored, event rate, image redundancy and sensor platform mobility. Response time increased significantly for increasing numbers of displays, as expected, but also increased independently for event rate image redundancy and for mobile sensors. Results showed that significant performance penalties may be encountered in multiple platform control, and that these penalties accumulate at seemingly low levels of complexity.
