94碩士論文:應用於居家環境之身體活動監測與評估系統之開發

  居家環境下的日常身體活動監測資料,可作為分析活動能力受限者或慢性病患健康狀態及生活品質的量化評估指標。本研究開發一個結合三軸加速度規與單晶片控制器的攜帶式身體活動感測與辨識裝置,以及運用無線數據傳輸與分散式資料儲存架構之硬體平台,用以即時監測並紀錄身體活動資料。本系統可主動即時辨識身體姿態、姿勢變換以及行走等日常身體活動項目,亦提供可能跌落意外事件之偵測與預警功能。由實驗驗證結果顯示,本系統對於各種靜態姿勢以及姿勢變換等身體活動項目,具備良好的辨識準確度。本系統亦於實地居家環境進行長時間監測,其結果亦可顯示完整的身體活動監測資料。最後本論文並討論現階段本系統即時活動辨識的主要技術限制,及未來可能的發展。

Development of a Portable System for Physical Activity Assessment in a Home Environment

  Quantitative assessment of daily physical activity in a home environment provides significant information in evaluation of health and the quality of life of subjects with limited mobility and chronic diseases. This study developed a system for human physical activity assessment in ambulatory monitoring using only one portable sensing device combining a tri-axial accelerometer and its distributed data processing platform. This real-time system is able to identify several postures, posture transitions and movements with the embedded algorithm. In addition, this system also features fall detection capability. The results of the test for evaluating the performance of the system show high identification accuracy for both still postures and dynamic movements. A long-term ambulatory test was also conducted, and the recorded data shows sufficient information of the subject’s activities of daily living at home. Some inherent limitations concerning real-time identification were discussed. Despite those limitations, this system is technically viable for ambulatory application to provide sufficient information in evaluating a person’s activity of daily living (ADL) and his status of physical mobility. Potential wok of this system in the future is also discussed.
