碩士 === 長庚大學 === 資訊工程學研究所 === 97 === The purpose of this study is to establish a spatial cognition and memory ability assessable system for the elderly with dementia. The research purpose of this study is: (1) Developing elder-orient entertainment games to assessment elder spatial cognitive ability. (2) Establishing searching strategy assessable algorithm to analyze the learning effect. (3) Collecting clinical data and the key indicators that are different between normal elder and dementia patient. We collected four groups’ data that includes normal young people, normal middle-aged person, normal elderly and dementia patient amount to 52. The results are showed as following: (1) The result of virtual Morris water maze showed that the latency time and the time percentage in the critical zone will grow as the age increases. (2) The result of card matching game showed that the identification error rate rises with the increase of age. (3) The correct rate of animal manager game (visual edition) reduced and the response time extended with increase of age. (4) The error rate of 12 card matching game obtained significantly high negative correlation with MMSE (-.753), and the other variables including: the latency time, the ratio of time in the critical zone, the reaction time and correct rate of animal manager game had medium correlation with MMSE. (5) The 8 card and 12 card error rate of card matching game were significantly difference in normal elderly and dementia patient. (6) The test-retest reliability analysis of water maze task showed had significantly correlation. (7)In the experiment environment of platform diameter is 16 pixels, the growth rate of hit rate of normal elderly is 13%, but there is no learning effect in dementia patient. (8) The results of spatial strategy analysis showed that the young people and the normal middle-aged person had learning effect visibly. But the normal elderly and the dementia patient will have no change in their search strategy. The learning effect is not apparent.
