B-1 Engineering Research Simulator (ERS) Data Link Study
Abstract
The primary objectives of this evaluation were to: (1) establish a B-1 defensive and offensive station base line performance using audio tasking, and (2) compare the base line performance with performance for a freetext message and an integrated mode. This study looked at interface issues, not specific hardware. Two part tasks, retargeting (OSO) and threat updating (DSO), were used. The dependent measures for both tasks were key strokes per target or threat, time per target or threat, errors per target or threat, and Subjective Workload Analysis Technique (SWAT). Repeated measures multivariate analysis of variance for the OSO task showed the integrated mode was significantly (p < 0.05) lower for number of strokes, time, errors and workload than the audio or freetext modes. Subjective rank ordering of the three modes indicated the WSO's unanimous preference for the integrated mode. Due to experimental constraints, only the audio and freetext modes were compared in the DSO task. The DSO results were mixed; audio performance was better for strokes but required more time than the freetext mode. The integrated mode is recommended for the OSO and DSO stations.
