Orion basic gestures

[arda.aytac]

Hello! This is my first time with orion and I'm a bit confused. I just tried my old code to work with basic gestures (key tap,swipe,circle) and its not worked with orion core assets. For example mycontroller.enablegesture function does not working. Thanks.
Edit: Working on unity. Also I havent got any head mount vr device like oculus. Just leap motion. Is this a problem for usin orion?

We removed the four built-in gestures in Orion. This was for a variety of reasons, but mostly because they never really worked well enough and worked even less well in VR.

So How can I do gestures in code? Or how can I get hands x,y,z position?

Gesture recognition is a complex task. For some alternatives to the formerly built-in recognizers, see https://community.leapmotion.com/t/gesture-recognizer/3174/2

Also, an ad hoc approach can work for simple recognition tasks, like a thumb's up, for example. If you can define the thing you are trying to recognize mathematically, then you can write an function that checks the math. For example, in the thumb's up case, you could check that the thumb is extended and its direction vector is more or less aligned with the coordinate system Up vector.

To get the hand position, and any other tracking data, you get a Frame object from the CurrentFrame property of the Unity asset LeapServiceProvider object. This Frame object contains a list of the Hand objects. You can get the position of the hand from the HandObject as PalmPosition.

I understood the software to be one of Leap Motion's biggest discriminators, so if Leap can't get gestures to work well, then how will developers? The alternative link below seems like a lot of work for each developer to do in order to get basic functionality working. Is there a tutorial or example that shows how basic interactions can be coded? I'm specifically looking for Unity/C#.

There is a Pinch tool package that demonstrated how to detect pinches (and it fully prefabbed and ready to use) for grabbing, scaling, rotating. It's on their download page for Unity tools.

I don't lament the loss of gesture/pose support, because it was a very high level way to interact with the hands. Interacting with poses takes you away from the raw data. The important thing to know is that their hand tracking is drastically improved and you can deal with each bones of each finger of each hand directly - it's dead simple to formulate your own interactions.

For example, I wanted to make a finger gun. I dropped a rigidbody collider on thumb-bone3 segment, and a collider trigger anchored to the palm. When the thumb moved down into the trigger zone (like the hammer of a gun) the gun fires. I'm not sure how I would have implemented that with high-level gesture/pose support, but the tools they have provided are very practical.

Thanks, conjoinedcats. Will try that.

Thank you guys for your helps.

So, for desktop apps, we should stick with version 2 ?

Keytap gestures are working very well, but new functionality is missing the V2 API, like pausing the controller.

It seems you are focusing on VR and not giving more support for Desktop apps.

I have discovered by accident that gestures work with version 3.1.2+40841_win.

This is because you added it in a later version, or they are not still removed from version 2 ?

[Joe_Ward]

They may still work with the old assets because they uses the older .dlls. The gestures in the service are deprecated. New code won't use them, but the service will still recognize them for now.
