應用於高齡照護之可攜式影像擷取裝置之設計與實作

台灣社會隨著高齡化的進展與少子化的影響，人口老化現象愈來愈明顯，其失智症老人大幅增加，而照護模式亦備受關注。一般高齡者及輕度失智症的四肢行動並未退化，因此日常生活作息上盡量讓高齡者可獨立自主生活，因此能隨即隨地記錄高齡者的行蹤將是一項非常重要的課題，如可以將高齡者的行蹤以影像每十秒或五秒記錄下來，必要時便能分析高齡者的行蹤；而目前市面上比較缺乏此類產品，例如使用消費型的數位相機或是數位攝影機，但是此類產品不是記錄影像空間不夠就是較為耗電無法長時間使用；本研究旨在應用嵌入式系統，發展一套可應用於高齡者或輕度失智症患者，自動記錄日常生活作息之影像擷取裝置。本研究發展之嵌入式系統，採用一般之通用型微控制器以及配合加速度計可偵測高齡者之行為模式，例如靜止或移動進而將重要的影像記錄間隔從十秒或五秒記錄一次影像，改變成二秒記錄一次或一秒記錄一次，使系統具有省電且價格低廉之優點，其所記錄下來的影像可提供醫師作為高齡者的行為判斷以及醫療照護之目的，¬而且將影像儲存在個人電腦上或儲存在個人雲端儲存裝置裏，可做為高齡者的記憶提取與回想之用，以達到輔助高齡者及輕度失智症患者獨立自主生活之目的。

With the progress of aging population and serious low birthrate in Taiwan, the phenomenon of aging society is getting more apparent and the amount of elderly people with dementia increases substantially. Therefore, the care model of elderly people with dementia has become an important topic. Due to the limbs action of elderly people with mild dementia is not fully degraded, their daily routines should be kept as free as possible. Therefore, the ability of recording the actions of elderly people at anytime and anywhere is a very important issue. If their actions can be recorded every 5 or 10 seconds as a series of images, it will be helpful for us to analyze their track, if necessary. However, the market is lack of such products. Although the consumer digital camera or digital video recorder can record the images, but the battery capacity and memory size cannot afford to record the actions for the whole day. In this study, we apply an embedded system to develop an image capture device, which is suitable for automatically recording the daily action of elderly people and mild dementia patients. The developed embedded system of this study applies general purpose microprocessor and accelerometer to detect the behavior of elderly people. By changing the recording interval of critical images to 1 or 2 seconds from 10 or 5 seconds, it will greatly reduce the power consumption to prolong the available system runtime, and reduce the overall system cost as low as possible. The recorded images could be stored at PC or the storage space provided by the cloud. With the recorded images, it can help the aging people and mild dementia patients to recall the track of actions and achieve the independence of their daily life. In addition to that, these recorded images will greatly assist the doctor to diagnose the behavior of aging people and dementia patients, and achieve the health care purpose.
