Effect Of Simulated Visual Impairment On Nighttime Driving Performance, Joanne Wood, Alex Chaparro, Trent Carberry, Byoung Sun Chu

Publications

Purpose. This study investigated the effects of simulated visual impairment on nighttime driving performance and pedestrian recognition under real-road conditions.

Methods. Closed road nighttime driving performance was measured for 20 young visually normal participants (M = 27.5 +- 6.1 years) under three visual conditions: normal vision, simulated cataracts, and refractive blur that were incorporated in modified goggles. The visual acuity levels for the cataract and blur conditions were matched for each participant. Driving measures included sign recognition, avoidance of low contrast road hazards, time to complete the course, and lane keeping. Pedestrian recognition was measured for pedestrians wearing either black …

Effect Of Time Pressure And Task Uncertainty On Human Operator Performance And Workload For Autonomous Aerial Vehicle Missions, Trevor Petersen

Master's Theses - Daytona Beach

Unmanned aircraft systems (UAS) are being utilized at an increasing rate for a number of military applications. The potential for their use in the national airspace is also of interest to the Federal Aviation Administration, but there are some concerns about the safety of flying unmanned aircraft. The role of a UAS operator differs from that of a pilot in a manned aircraft, and this new role creates a need for a shift in interface and task design in order to take advantage of the full potential of these systems. This study examined the effect of time pressure and task …

Integrating Situation Awareness Assessment Into Test And Evaluation, Cheryl A. Bolstad, Haydee Maria Cuevas

Publications

To guarantee the success if network- centric operations, warfighters need the ability to extract and share critical task-relevant information to develop and maintain the situation awareness that is so critical far effective team performance. As such, the design of emerging technologies and systems must adopt a "user-centric" approach, with consideration for human information processing capabilities and limitations. In turn, to ensure that these technologies and systems are meeting their design objectives, test and evaluation must similarly be expanded to include metrics that assess how well system features and functions are supporting critical human cognitive processes such as situation awareness and …
