Examining the effects of ecological models of situation displays on human cognitive effort

摘要

This paper reports on an observational study of cognitive eforts associated with ecologicla-based situation displays. The major performance measure is an 8-item subjective questionnaire. participants in the study indicated on a 100-point scale, from zero (poor) to 100 (absolutely useful), their agreement with statements addressing information factors contributing to cognitive effort measurements. Two types of situation displays were compared: scenario and ecotopic displays, respectively. A scenario-based display portrays complete informaitn about a problem context. An ecotopic display presents only local information and adapts to the user's mental model in a problem context. Results revealed that an ecotopic display provides better information filtering and mental model mapping than a scenario-based display (96.53
