高齡年長者或是大部分的肢體障礙患者會有行動困難而必須藉由移動式輔具，也就是輪椅或電動代步車做為出入移動的需求，而對於重度失能患者，因為長期臥病在床，若疏於照護沒能適時翻身，很容易就會有壓褥瘡。而如何透過智慧科技的運用，提供高齡年長者或身心障礙者更優質、便利的服務，也是目前相關研究的重點，因此本論文研究主要針對高齡年長者或身心障礙者服務，應用穿戴式裝置與物聯網技術，透過設計思考之方法提出情境設計與解決方案，及設計應用的評估。在本論文中，主要探討以物聯網相關技術應用在建立醫療設備介面的開發，因此無線控制是本文開發的重點。為了達成上述目的，我們使用了訊息佇列遙測傳輸協定（Message Queuing Telemetry Transport，MQTT）、藍牙等技術，硬體部分使用慣性測量單元（Inertial measurement unit，IMU）、HM-10藍牙模組；軟體介面的部分，手機平板應用APP使用App Inventor來撰寫程式，底層控制端使用ATmega2560晶片進行整體的運行與控制。最後，本論文以自行研發改裝之電動輪椅、電動娃娃車與聲控翻身氣墊床為測試平台進行實驗與驗證。

The elders and patients with physical disabilities have difficulty in mobility, and electric wheelchairs and scooters would be possible mobility aids in their daily life. Severe disability patient with long-term illness in bed situation may use active pressure bedsore to change the body posture to prevent pressure ulcer. To provide the abovementioned patients having better quality of life through the uses of up-to-date technologies is the aim of this research. Therefore, this thesis mainly aims at developing the wearable devices with Internet of Things (IoT) techniques to provide a feasible human-machine-interface for disabled patient in terms of scenario design, solution implementation and validation. This thesis mainly discusses the applications of IoT in the development of wireless medical device control interface. In order to achieve the above goals, the technologies of MQTT (Message Queuing Telemetry Transport) and Bluetooth were employed. For the hardware aspects, the inertial measurement unit (IMU) and HM-10 Bluetooth modules were used. For the software aspects, the mobile tablet APP was realized with APP inventor. An ATmega2560 microcontroller was used to connect the APP and wearable sensors modules and the physical medical devices. Finally, the proposed interfaces were validated in terms of modifying the commercial available facilities of an electric wheelchair, an electric baby car and an active pressure bedsore.
