Multifactor Determinants of Visual Accommodation as a Critical Intervening Variable in the Perception of Size and Distance: Phase I Report
Abstract
The accuracy of visual perception, specifically, the accuracy of size and distance judgment, affects human performance at the boundary of today's display technology envelope. A variety of long standing and state of the art contact and contact analog display and media technologies (including virtual reality and environmental displays) are being specified and engineered without the benefit of critical and fundamental information that is now accessible. This technical report takes a conceptual, meta-analytical approach to evaluating a multidisciplinary literature regarding this domain. The findings converge, across a wide variety of clinical, experimental, and psychophysiological research, on an integrative conceptual framework. They support the value of researching a hypothesized set of relationships between the human visual syntactic triad and the perception of size and distance. Specifically, measurable visual accommodative subsystem states and specifiable processes are implicated as critical intervening mechanisms. These mechanisms have the potential to provide avenues for prediction and practical intervention. This technical report is a stand alone tutorial and is the final product of the background research phase for WU 1123-C3-94. At submission, instrumentation for the experimental phase of this work unit is nearing completion.
