A Psychophysical Approach To Standardizing Texture Compression For Virtual Environments, Jeremy Flynn
A Psychophysical Approach To Standardizing Texture Compression For Virtual Environments, Jeremy Flynn
Electronic Theses and Dissertations
Image compression is a technique to reduce overall data size, but its effects on human perception have not been clearly established. The purpose of this effort was to determine the most effective psychophysical method for subjective image quality assessment, and to apply those findings to an objective algorithm. This algorithm was used to identify the minimum level of texture compression noticeable to the human, in order to determine whether compression-induced texture distortion impacted game-play outcomes. Four experiments tested several hypotheses. The first hypothesis evaluated which of three magnitude estimation (ME) methods (absolute ME, absolute ME plus, or ME with a …
Human Factor Effects Of Simulating Battlefield Malodors In Field Training, William Pike
Human Factor Effects Of Simulating Battlefield Malodors In Field Training, William Pike
Electronic Theses and Dissertations
In order to explore how to better utilize simulated odors for live training, a study of 180 United States Military Academy at West Point cadets was undertaken to determine whether pre-exposure to a simulated malodor may result in an amelioration of performance issues, as well as improving performance of a complex task. Exposure to malodors has long been shown to increase stress and escape behavior, and reduce performance of complex tasks, in addition to degrading other human factor areas. However, desensitization to a particular odor through a process known as olfactory adaptation, could ameliorate these performance issues. In this study, …
Eye Movements And Spatial Ability: Influences On Thinking During Analogical Problem Solving, Bradford Schroeder
Eye Movements And Spatial Ability: Influences On Thinking During Analogical Problem Solving, Bradford Schroeder
Electronic Theses and Dissertations
Classic studies have examined the factors that influence the way in which people can solve difficult "insight" problems, which require creative solutions. Recent research has shown that guiding one's eye movements in a pattern spatially congruent with the solution improves the likelihood of formulating a spatial solution. The authors in this line of research argued that guiding eye movements in a pattern spatially equivalent to the solution of the problem yields an embodied cognitive benefit that aids problem solving. Specifically, guiding eye movements leads to the generation of a mental representation containing perceptual information that helps a problem solver mentally …
The Effect Of Religious Dress On Perceived Attractiveness And Trustworthiness, Courtney Swank
The Effect Of Religious Dress On Perceived Attractiveness And Trustworthiness, Courtney Swank
Electronic Theses and Dissertations
The hijab, a symbol of modesty and privacy in the Islamic faith, negatively affects ratings of perceived attractiveness. Although postcolonial feminism strives to portray women as not one universal group, but as an incorporation of different races, ethnicities, social classes, and other cultures, the Western world may not be where it endeavors to be. In this study the impact of the hijab on people’s perceptions of attractiveness was examined. Participants rated four target photos of the same woman with and without a hijab, and with or without cosmetics. Attractiveness and trustworthiness was then assessed in each condition, between genders, in …
