摘要

本論文提出一應用於居家環境下的高齡者身體活動與行動力監測系統。本研究以分散式遠距居家照護系統為架構，開發身體活動監測，以及居家日常生活活動監測兩大項目。本研究中開發可穿戴式活動偵測器，運用加速度量測法與即時訊號運算技術以精確量測身體活動，可達成即時身體活動辨識、跌倒偵測、身體熱量消耗預測、以及步態分析與辨識等功能。除身體活動監測外，本研究亦開發居家日常生活活動監測技術，可針對居家環境下的獨居高齡者進行長期的居家日常生活活動監測。長期的居家日常生活活動資料可反映出高齡者的生活作息模式，本論文亦提出日常生活活動監測數據之特徵分析，可提供量化的指標，作為充分且客觀了解高齡者的整體功能狀態並評估其健康狀態與生活品質之方法。本活動監測系統適合於居家環境下使用，監測資料與分析結果並能夠做為評估高齡者行動力與功能狀態之依據。未來本研究開發系統與監測技術亦可延伸至其他應用領域，如可用於輔助復健、個人遠距看護、或智慧住宅等相關應用。

This thesis presents the development of a home telehealth system for physical activity and mobility telemonitoring for the elderly based on the decentralized home telehealth system. This system incorporates the use of an accelerometry-based wearable motion detector and the home activity sensors to monitor physical activity and activities of daily living (ADLs), respectively. The wearable motion detectors achieved the capabilities of real-time activity identification and fall detection, estimation of energy expenditure (EE), and real-time recognition of gait cycle parameters. The home ADL monitoring can provide the rhythms of daily activities on a long-term basis. The ADLs can be further characterized by means of the ADL features that indicate the activity performances in terms of intensity, frequency and regularity. The monitoring system is demonstrated to be technically-feasible and suitable for home use and can provide sufficient and detailed information to facilitate the assessment of mobility and functional ability of the elderly people. In addition to the home use, this monitoring system is expected to benefit and assist rehabilitation, personal tele-care and smart home applications in the future.
