Stereoscopic Vision's Impact On Spatial Ability Testing, George Takahashi
Stereoscopic Vision's Impact On Spatial Ability Testing, George Takahashi
Purdue Polytechnic Masters Theses
A look into spatial ability testing tools and the variations that past researchers made to focus on key factors that affect test scores, will demonstrate the need for tuning traditional testing methods to accommodate a wider demographic and provide more accurate results. Due to technological limitations of the time, a large variety of past spatial tests were developed by hand-drawings. Within this research, the addition of stereoscopic vision is analyzed to determine the value of said changes on human perception of spatial entities.
A Comparison Of The Effect Of Variations To U.S. Airport Terminal Signs On The Successful Wayfinding Of Chinese And American Cultural Groups, Steven Leib
Purdue Polytechnic Masters Theses
Processing passengers quickly and efficiently is one of the top goals for airport administrators, and major international gateways have the added challenge of processing passengers representing a variety of cultures and nations. People having diverse cultural backgrounds may interpret signage layouts differently with respect to symbols and text. Consequently, dedicated research into signage perception may provide airport administrators with a more informed sense of how to convey appropriate movement and directional information within their terminals. There are many ways to answer the broad question of what signage encourages passengers to move most efficiently through an airport terminal. This study focused …
Effects Of Lighting Phenomena On Perceived Realism Of Rendered Water-Rich Virtual Environments, Micah L. Bojrab
Effects Of Lighting Phenomena On Perceived Realism Of Rendered Water-Rich Virtual Environments, Micah L. Bojrab
Purdue Polytechnic Masters Theses
This study investigates the effects of various common lighting phenomena on human perception found in water-rich virtual environments. The investigation uses a traditional Psychophysical Analysis (PPA) to examine viewer perception of these lighting phenomena as they relate to rendering cost and reveals common trends in perceptual value among the phenomena. The work includes the use of a web-based testing system, proposed for the first time in familiar literature. The system includes five scenes with eight common lighting variables. Every scene depicts a different water scenario, but each shows every lighting phenomenon. The animated videos are rated in order of realism …
