Outline of Final Research Achievements

Various disturbances of visual space recognition include unilateral spatial neglect (USN) has been strongly associated with an increased risk for injury and with poor functional outcome. To quantitatively evaluate visual spatial impairment in cerebrovascular disease patients, we developed a new measurement system able to present a versatile visual information. The results suggested that our new head mounted display (HMD) system has a possibility that the spatial neglect disorder clarify a significant symptom of USN that has not been found out by a common examination on two-dimensional paper in a three-dimensional space. In addition, we have developed a 3D-HMD system with small position sensors which have found the possibility of supporting gait and activities of daily living (ADLs) for patients with visual spatial cognitive impairment as an assistive device.
