Hey,
I wanted to share the result of my thesis which is using the Leap Motion controller 
I experimented with Virtual Reality, Augmented Reality and the Internet of Things. To control everything I used the Leap Motion controller. I did this 2 years ago, but it may still be interesting for some of you.
Unfortunately I don't have a video showing all the functions implemented but most of them are in this one
Also this small one shows some other function:
There is also an article on the blog of the company I did the thesis (in german): https://blog.doubleslash.de/ariot-prototyp-iot-in-verbindung-mit-augmented-reality/ There are some small videos showing the other functionalities.
For development I used
- Unity Game Engine
- Vuforia AR framework
- Leap Motion
- Oculus Rift DK2
- ThingWorx IoT platform
So hopefully this is helpful for you and gives you some ideas for your projects I was really pleased using the Leap Motion controller for this.
Best
Nico
