碩士 / 國立雲林科技大學 / 工業工程與管理系 / 102 / Because of the emergence of an ageing society, problems concerning dementia patients have become increasingly prominent. Although no medication that can improve or at least maintain the cognition of Alzheimer's disease (AD) patients has been developed, maintaining the life quality of patients is a primary concern. Becoming lost is a major symptom that presents at the early stage of AD. In a previous study, we observed that a navigation system can improve and almost normalize the way-finding ability of early AD patients. In this study, we explored problems regarding various navigation systems and the way-finding performance of users in various environments.
In Experiment 1, we developed a navigation system application for smart phones to evaluate the way-finding performance of three groups (healthy elderly people vs. AD vs. mild cognitive impairment) at two forking angles (90° vs. 135°) and in using different modes to change floors (elevator vs. stairs). In Experiment 2, we examined how a cue of illumination (cue of illumination vs. no cue of illumination), the navigation viewpoint (first-person viewpoint vs. third-person viewpoint), and light indication (light indication vs. no light indication) affected the performance of the three groups (healthy elderly person vs. AD vs. mild cognitive impairment (MCI)). The results of Experiment 1 revealed that AD patients who used the navigation system application for smart phones exhibited an accuracy rate equal to that of MCI patients and healthy elderly people. Furthermore, the performance of healthy elderly people in using different navigation displays was favorable. MCI patients could perform as well as healthy elderly people could except when using the first-person viewpoint and no cue of illumination or light indication. AD patients performed the most favorably when using the first-person viewpoint, the cue of illumination, and light indication.
