Unity 5.3.3p1 - Leap Motion V2 & Orion - Touch & Pinch Basic Help - C#

Hello,

I'm looking for a tutorial on how to do the most basic interactions of Touch and Pinch. I want to touch buttons (or Press) and Pinch (for example) GameObject's in Unity. Say to press a button on a UI and pinch a slider thumb to adjust the volume on an audio device.

Very basic interaction. I'll worry about complexity, as needed, later.

Anyone have an example in C# for Unity 5?

Thank you.

Pinch Utilities v1.0

Thanks. I used this as a place to start from and it's working now.

I noticed a second pair of pink colored forearms and hands. They move (but don't pinch) in concert with the default hands (blue and green). I'm wondering what I need to do to remove such? I'm going through now to see. It must be something simple I did wrong, or added when I should not have.

As far as I know, I just duplicated the example in the PinchUtility > Examples folder in my project.

Ideas on the pink duplicate set?

Thanks for your help.

--- UPDATE ---

I just disabled (shift-selected all objects below the CapsuleHand_L (and will do for R), and that removed the pink duplicates, while maintaining the pinch function. Wonder why it was like that by default. Maybe your thought on that?

--- UPDATE 2 ---

I ended up removing the components described in the first update. So far all has been working good.

Thanks again.

I don't get it.. This demo is great but it's not open source so how can it help ?

Pinch Draw and Pinch Move are both open source. Their Unity package can be found at https://developer.leapmotion.com/unity?#modules

I downloaded the executable, I can play with the demo but I don't find the code ...

That's because you need to download the Unity package. It's located here: https://developer.leapmotion.com/unity#modules

Click the "Pinch Utilities v1.0" link and it will download.

aaaaaaaaah didnt see I could click on that !! Sorry and thank you I thought I was becoming crazy

Its cool actually but their pinch recognition is probably hardcoded as it was before.. I'd like to find some gesture recognition learned with machine learning algorithm, do you know if/where I can find that ?

No worries, I agree that it could be clearer. We're going to see about changing the link color.

There are many gesture recognition and machine learning projects, but I'm not sure that there are any available for C#/Unity. LeapTrainer is a few years old at this point, but it's fully open source, and might be a good starting point: http://blog.leapmotion.com/building-a-web-based-motion-interface-with-leaptrainer/

Heh, you weren't the only one mate

I cant find this anymore, can you please tell me where to find it now? It would love to play around with the pinch move scene!
Thanks in advance.

It's in the now-deprecated Detectors Module: https://developer.leapmotion.com/releases/detection-examples-104
