Kinect2.0UnitySDK在unity中使用之手勢識別
1：新建項目，導入KinectUnitySDK， 新建空物體并掛載KinectManager腳本

2：修改腳本CubeGestureListener 中的UserDetected方法，將要識別的手勢添加進去。

3：修改腳本CubeGestureListerner中GestureCompleted方法，添加要識別的邏輯；

在此Demo中我只做了揮左手以及揮右手的邏輯，具體看自己需求來拓展以上方法；以下是該腳本的全部代碼：

SDK提供全部手勢識別的枚舉全在以下代碼中，可根據需要自定義識別邏輯；

public enum Gestures {None = 0,RaiseRightHand,//右手舉起過肩并保持至少一秒RaiseLeftHand,//左手舉起過肩并保持至少一秒Psi,//雙手舉起過肩并保持至少一秒Tpose,//觸摸Stop,//雙手下垂Wave,//左手或右手舉起來回擺動Click,//左手或右手在適當的位置停留至少2.5秒SwipeLeft,//右手向左揮SwipeRight,//左手向右揮SwipeUp,//左手或者右手向上揮SwipeDown,//左手或者右手向下揮RightHandCursor,//假手勢，用來使光標隨著手移動LeftHandCursor,//假手勢，用來使光標隨著手移動ZoomIn,//手肘向下，兩手掌相聚至少0.7米，然后慢慢合在一起ZoomOut,//手肘向下，左右手掌合在一起（求佛的手勢），然后慢慢分開Wheel,//想象一下你雙手握著方向盤，然后左右轉動Jump,//在1.5秒內髖關節中心至少上升10厘米 (跳)Squat,//在1.5秒內髖關節中心至少下降10厘米 (下蹲)Push,//在1.5秒內將左手或右手向外推Pull,//在1.5秒內將左手或右手向里拉ShoulderLeftFront,//左肩前傾ShoulderRightFront,//右肩前傾LeanLeft, //身體向左傾斜LeanRight, //身體向右傾斜LeanForward,//身體向前傾斜LeanBack,//身體向后傾斜KickLeft,//踢左腳KickRight,//踢右腳Run,//跑RaisedRightHorizontalLeftHand,//左手平舉RaisedLeftHorizontalRightHand,//右手平舉//自定義手勢UserGesture1 = 101,UserGesture2 = 102,UserGesture3 = 103,UserGesture4 = 104,UserGesture5 = 105,UserGesture6 = 106,UserGesture7 = 107,UserGesture8 = 108,UserGesture9 = 109,UserGesture10 = 110, }

到此手勢識別功能已實現，記錄下來避免后續忘記。。
