"Recent investigations have demonstrated that the loss of perspective sensory correlates with an early stage of Alzheimer diseases (AD). Our previous study measured this sense by stereopsis viewing. By cross-eye stereogram, a computer generated object images at given distance from monitor. The perspective sensory is measured as a difference of subject’s sense and given distance. The experiment was conducted for two groups: ordinary person and AD patient. The experiment resulted in statistical significance. Our object is to establish a novel measurement method for perspective sensory based on 3D glass-free display. This display has no needs for LCD shutter glass and has an advantage to have more natural viewing. However, using 3D glass-free display has some of the difference against the previous effort. We tried to measure the perspective sensory within modeling space and three virtual objects. Two objects are fixed on given position in horizontally. The third object is centered between two objects and moved from infinity to the nearest. The subject moves the center object to make line with two fixed objects. This paper reports a preliminary experiment for perspective sensory measurement. We have an examination for ordinary people and verify a tendency for a comparative experiment with AD patient."
