現有的懸浮手勢解鎖方式大多以光感傳感器 (light sensor) 和距離傳感器 (proximity sensor) 達到解鎖之目的，但無法真正以手勢辨識作為解鎖之判斷依 據。因此，本論文提出一種以懸浮手勢透過前景鏡頭將手機螢幕解鎖的方式， 稱之為Air Gesture Unlock。Air Gesture Unlock 利用膚色分析及手勢辨識之方 法可提供使用者一種更便利及更實用之解鎖方式。

This thesis presents a method for air gestures to unlock screen on mobile devices. In the advance technology on the mobile devices, light intensity or proximity is mainstream for unlocking sensors for the mobile screen unlock. This paper proposes a method with color detection and gesture recognition for an easy and useful way to unlock mobile device screens.
