以肢體動作為基礎的人機介面一直被認為是未來家庭人機介面的表徵，然而，由於缺乏適合的應用環境和辨識技術，相關的應用尚未成熟。本研究嘗試提出一個互動式仿鏡顯示裝置作為肢體指令的平台，並提出相關的辨識技術，以設計一個可應用在智慧家庭環境中，符合人因工程的互動顯示裝置。 / Gesture-based user interfaces have long been associated with the image of future technology. However, due to the lack of proper environments and recognition technologies, practical applications of intelligent user interfaces are still rare in modern life. In this research, we propose an interactive mirror which can be controlled by gesture commands. We also provide several recognition techniques for this interactive display device. Practical applications are developed on this smart mirror, and user test is conducted to evaluate this novel user interface.
