The Accuracy Of Observers' Estimates Of The Effect Of Glare On Nighttime Vision: Do We Exaggerate The Disabling Effects Of Glare?, Stacy Balk
All Dissertations
Designing headlights involves balancing two conflicting goals: maximizing visibility for the driver and minimizing the disabling effects of glare for other drivers. Complaints of headlight glare have increased recently. This project explored the relationship between subjective (discomfort and expected visual problems) and objective (actual visual problems) consequences of glare. Two experiments - a lab-based psychophysical study and a field study - quantified the accuracy of observers' estimates of the effects of glare on their acuity. In both experiments, participants over-estimated the extent to which glare degraded their ability to see a small high contrast target. Observers' estimates of the disabling …
Spatial Perception And Robot Operation: The Relationship Between Visual Spatial Ability And Performance Under Direct Line Of Sight And Teleoperation, Joshua Gomer
All Dissertations
This dissertation investigated the relationship between the spatial perception abilities of operators and robot operation under direct-line-of-sight and teleoperation viewing conditions. This study was an effort to determine if spatial ability testing may be a useful tool in the selection of human-robot interaction (HRI) operators. Participants completed eight cognitive ability measures and operated one of four types of robots under tasks of low and high difficulty. Performance for each participant was tested during both direct-line-of-sight and teleoperation. These results provide additional evidence that spatial perception abilities are reliable predictors of direct-line-of-sight and teleoperation performance. Participants in this study with higher …
