I was playing around with Augmented Reality using Qualcomm Vuforia and Unity, and decided to integrate it with a Philips Hue Lamp.

You can get started with Augmented Reality by following this nice and short tutorial (I do not own this video):
Instead of importing a vehicle (as the guy in the tutorial), you can import the functioning Light Switch Asset:
https://www.assetstore.unity3d.com/en/#!/content/23468
The switch is meant for mouse click, but you can modify it with the code above in order to have it work with touch input.
