Virtual Reality Based Assessment Tool for Measuring Human Perceptual Sensitivity to Erroneous Motion

摘要

Recent advances in neuroscience have shown that the neuropathological disorders are closely related with diseases such as Alzheimer's. Those damages are particularly associated with the intermediate visual perceptual processing which can cause the motion perception defects and abnormal visuo-spatial functions in daily living of patients. In this paper, we propose a virtual reality based assessment tools for measuring human perceptual sensitivity to dynamic erroneous motions, particularly designed to assess possible early stage of brain damages and its associated visual dysfunctions. The proposed method contains multiple assessment layers to check the awareness of erroneous motion in natural scenes at various severities. Our VR based game type environment provides an effective test bed for various dynamic motion based perceptual sensitivity experiments. Our initial human subject tests show that game based test environment produces more coherent and consistent data, preferable to survey based methods.
