<p>Take a look at what leap frog has done with the oculus rift. I'm not sure what they're using internally to segment hand poses, but there is another paper that produces hand poses effectively. If you have a stereo camera setup, you can use this paper's methods: <a href="https://arxiv.org/pdf/1610.07214.pdf" rel="nofollow noreferrer">https://arxiv.org/pdf/1610.07214.pdf</a>.</p>

How to detect hand palm and its orientation (like facing outwards)?
<p>I am working on a hand detection project. There are many good project on web to do this, but what I need is a specific hand pose detection. It needs a totally open palm and the whole palm face to outwards, like the image below:<br>
<a href="https://i.stack.imgur.com/tS61S.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tS61S.jpg" alt="left hand will not be detected"></a></p>

<p>The first hand faces to inwards, so it will not be detected, and the right one faces to outwards, it will be detected. Now I can detect hand with OpenCV. but how to tell the hand orientation?</p>
