Non Intrusive Measures for Determining the Minimum Field of View for User Search Task in 3D Virtual Environments

Abstract—In this paper, we report on an experiment to determine the minimum field of view that permits the user to perform an effective search task in a 3D virtual environment, by analyzing how the user controls the virtual camera. Our study exploits a model based on the use of several novel non-intrusive temporal and quantitative measures of visual attention, such as: fixation, gaze, and movement. Seven out of ten measures gave significant results with the same findings. Keywords-Field of view; virtual environment; video games; visual attention. I
