Title
An Investigation of Visual Cues used to Create and Support Frames of Reference and Visual Search Tasks in Desktop Virtual Environments
Abstract
Visual depth cues are combined to produce the essential depth and dimensionality of Desktop Virtual Environments. This study discusses Desktop Virtual Environments in terms of the visual depth cues that create and support perception of frames of references and accomplishment of visual search tasks. This paper presents the results of an investigation that identifies the effects of the experimental stimuli positions and visual depth cues: luminance; texture; relative height; and motion parallax on precise depth judgements made within a Desktop Virtual Environment. Results indicate that the experimental stimuli positions significantly affect precise depth judgements, texture is only significantly effective for certain conditions and motion parallax, in line with previous results, is inconclusive to determine depth judgement accuracy for egocentrically viewed Desktop Virtual Environments. Results also show that exocentric views, incorporating relative height and motion parallax visual cues, are effective for precise depth judgements made in Desktop Virtual Environments. The results help us to understand the effects of certain visual depth cues to support the perception of frames of references and precise depth
