Perceptual Gaze Extent & Level Of Detail in VR: Looking Outside the Box

studies is that eye movements made while immersed in VR generally do not deviate more than 30 (visual angle) from the head-centric view direction (e.g., see Barnes [1979]). In this sketch we report eye tracking evidence which generally supports this observation in the context of peripheral Level Of Detail management during a visual search task in VR. We present results from experiments based on the work of Watson et al. [1997] and discuss an extension to the peripheral degradation paradigm to include a dynamic eye-slaved high-resolution inset. EXPERIMENTAL TECHNIQUES To investigate perceptual gaze extent in VR, we began by replicat-ing the experiments of Watson et al., where the objective of the study was the evaluation of peripheral degradation for bandwidth reduction during a visual search task. Watson et al. found that a static high-resolution window of 30 in a low-resolution 75:
