UNCLASSIFIED /qhe@-RaQ@ihbG iil tS Ea ile Cognitive Limits on Simultaneous Control of Multiple Unmanned Spacecraft Summary Space exploration 40 years into the future may include manned missions to parts of the outer solar system. A possible scenario may include sending a small fleet of craft with different primary missions. For example, a trailing spacecraft of nuclear powered electromagnets designed to shield the manned part of the fleet from solar radiation; halo spacecraft with powerful radars to scout for incoming objects; exploration and mining craft, etc. The fleet could regularly travel…

UNCLASSIFIED / / F@R-@5F26hH=US One Chapter 1: Introduction Due to the complexity, duration and numerous support requirements of future manned deep-space missions involving exploration, mineral exploitation, and possible colonization, a likely scenario will be the inclusion of unmanned fleets of support craft. Coupled with other requirements, an intensive research program is needed to investigate the cognitive limits on pilots and other operators responsible for the simultaneous control of multiple unmanned spacecraft making up the support fleet; a “fleet’ approach is proposed in an effort to …

UNCLASSIFIED / /802-@5F1Gh=-U6E-ONe=== audio processing, and this is where multiple resource theory enters: different resources can be considered independent if demands on one resource do not tax the availability of capacity of the other. Performance of a task can be high or low: in general if spare capacity is available, performance is high, and if capacity is limited or exceeded, performance is low. Moreover, task demand enforces a fixed theoretical relationship between mental workload and task performance: this is shown in Figure 1. Relationship between Workload and Task Performance High Pe…

UNCLASSIFIED / /@0-R-@FFLGHM = USPreorne: Chapter 2: Measurement of Mental Workload There are three approaches to measuring mental workload in a subject performing a primary task. The first is subjective evaluation, either post-hoc self-report questionnaires concentrating on how “busy” one may have felt, or an experimental observation of activity. The second is performance measures, an objective evaluation of how well the subject completes the primary task, a secondary task, or an experimentally inserted reference task. The final approach is to record real-time physiological measures, with the…

PERFORMANCE MEASURES Laboratory, reaction time to an event stimulus is a typical real-time measure of speed. Outside the laboratory, in a more natural environment, speed is an indirect measure of a subject’s ability to keep up with a given rate of events.? Accuracy is measured in both the laboratory and naturalistic environments: for example, in an air-traffic control task, properly handing off a plane to the next controll…
