UWF Human Factors Laboratory
The Human Factors Laboratory is under the direction of Dr. Steven Kass. In general, human factors research provides the knowledge to design systems that optimize human performance by compensating for human limitations and capitalizing on human strengths. Studies conducted in the laboratory have focused on attentional issues such as situation awareness, distraction, and tactile feedback and how they impact performance in driving and other psychomotor tasks.
Situation Awareness (slide presentation)
Situation awareness involves the ability to recognize, interpret, and integrate key patterns in the environment to accurately assess one’s current status and projection of future status. Good situation awareness allows one to react quickly in making crucial decisions. While situation awareness has been studied extensively in the military, this concept applies equally well to other environments such as driving and sports.
Haptic Responses to Visual-Spatial Stimuli (w/ NAWCTSD)
Due to verbal mediation, it is believed that perceptions that are often reported inaccurately, though the perception itself may be accurate. A more directly mapped response (psychomotor) may alleviate this problem. The idea is being tested for the task of submarine periscope operator.
Vibrotactile Displays for Spatial Awareness (w/ IHMC)
In situations where visual attention is diverted and/or under high cognitive workload, pilots may get spatially disoriented. A vibrotactile display is being tested to provide pilots spatial information through the relatively underutilized medium of tactile information.
Virtual environments (VE) and virtual reality are relatively new technological advances in training. Because of this, we currently know very little about their effectiveness or best use for training. One area of interest is to investigate mental maps of spaces visited only in VE transfer to the real spaces.
Sopite Syndrome Scale (w/ NAMRL)
Individuals experience different reactions to motion. Many people feel sick or nauseated while riding on a boat or amusement rides. However, motion may also lead to feelings of sleepiness (e.g., a baby rocking in a swing). This is called Sopite Syndrome and is a particularly dangerous reaction to motion for pilots. A scale is being developed to identify when someone may be experiencing the symptoms of Sopite Syndrome.
Human Factors and Aging
Attributing the Cause of Mishaps Involving the Elderly (UWF Small Grant)
According to Fundamental Attribution Error, when attributing the cause of an accident, observers are likely to overemphasize the impact of the characteristics of the person involved, rather than the circumstances surrounding the event. Though this is a common error, this may be particularly dangerous for some members of the population. For instance, if an elderly person is involved in a serious mishap with a piece of equipment, we are likely to overemphasize stereotypical aspects of the elderly, and dismiss the fact that the equipment may be inadequately designed for this portion of the user population.
The Relationship between Boredom Proneness, Vigilance, and Attention Deficit Disorder
The ability to maintain attention for long periods of time (i.e., vigilance) is importance for performing many tasks, such as truck driver, assembly line worker, air traffic control, etc. Some individuals may be at a disadvantage for performing these types of task. For instance, vigilance tasks may be expected to be particularly difficult for individuals who are prone to boredom or have been diagnosed with attention deficit disorder (ADD). This study is examining whether vigilance performance can be predicted by scores on paper and pencil measures of boredom proneness and ADD.
