無線射頻技術結合三軸加速度計監測人體活動量
RFID Combined with Accelerometer to Monitor Human Activity
摘要
RFID無線射頻辨識技術已在台灣發展多時，並活用於學生証、悠遊卡等個人專屬服務，以實現智慧生活化的理想目標。而本團隊因於教育部RFID應用於校園安全監控計劃中擔任監控在校學童之活動量。 由於現代社會發展快速，人類的科技文明造就了現今的社會，快速、便利是科技成長的主因，卻因如此人類由於過於的方便開始懶惰而造成文明病。反觀當今社會的學子學童們是否過度缺乏活動而使身體漸微虛弱導致容易身體不適或過於肥胖等問題，雖目前無任何科學可明確指出活動量與健康關係或是肥胖程度有一定指標，然而以往作調查活動量的方式大部分皆以問卷調查為主，但問卷受限於受訪者與出卷者的認知上差異、有限的記憶、社會期待等而造成問卷不確實。屆時本團隊開始研發三軸加速度感測器與RFID技術作為結合，並配置於人體上開始量測一天所累積的活動指數，再建置資料庫已利於多筆資料分析。並成功的量化出活動量數據，並得到活動量與呈現出活動、肥胖關係，雖目前無法正確地指出相關係數，但後繼實驗上已建立更完善資料庫並加以分析。希望此技術與資訊能供給後人參考。

RFID technology has long been developed in Taiwan and applied to personal services, such as student ID cards and EasyCard cards to make the “smart” lifestyle a reality. The mission of this team is to monitor the activity levels of students through the Application of RFID as part of the Campus Safety Monitoring Project of the Ministry of Education. Although speed and convenience are the causes of technological advancement driving rapid social changes, diseases of civilization arise from the inertia that results from over-dependency on the convenience brought by modern technologies. There is no direct scientific evidence indicating the correlation between the lack of activity and physical weakness, discomfort and even obesity in students; furthermore, most past studies on activity levels were questionnaire-focused, which are controversial as a result of the cognitive difference between the surveyor and respondent, memory limits and social expectations. This team has developed a device integrating the tri-axis accelerometer and RFID technology to measure the accumulative daily activity index of subjects who carry the device with them. A database was established to collect these daily activity results to facilitate further analysis in order to investigate the correlations between activity, health and obesity. On the other hand, the online search system allows teachers and parents to search the related data in order to understand the present condition of students.
