Alzheimer disease, 3D glass-free display, sensory perspective measurement

Recent investigations demonstrate that perspective sensory loss correlates with early Alzheimer Disease (AD).Our previous studymeasured this through stereopsis. Based on cross-eyed stereography, a computer generates images at a given distance from a monitor. Sensory perspective is measured as the difference between a subject’s sense and a given distance. Experiments conducted for non-AD and AD subjects showed different, statistically significant results. The measurement we propose for sensory perspective without the use of 3D glasses eliminates the need for LCD shutter glasses and provides much more natural viewing. We measured sensory perspective within modeling space and 3 virtual objects – 2 fixed at a given location horizontally and 1 centered between the other 2 objects and moved from infinity to the nearest point. The subject moves the center object to line it up with the 2 fixed objects. We report results of preliminary experiments on measuring sensory perspective. Subjects included non-AD and AD cases.
