问题
I'm using kinect V2.0. I need to perform click using grip gesture. Is there a way to handle the Grip gesture in V2.0 like AddHandPointerGripHandler in V1.8.
回答1:
In Microsoft Kinect SDK v2.0, the Body class includes two properties:
- Body.HandRightState
- Body.HandLeftState
Both these properties are instances of the HandState enumeration, which specifies if the hand is:
- Closed (and you can detect this to trigger the Grip gesture);
- Lasso (which means that the hand is closed in a fist, except for a finger pointing upward)
- Not Tracked (the hand state is not tracked)
- Open (the hand is open)
- Unknown
If you want to detect the Grip gesture, you can use a variable to save the last hand state detected, and then a "click" can be triggered every time this variable pass from an Open state to a Closed one.
Obviously, all of this can be executed every time you detect a SkeletonFrame.
