Smartphone-based virtual reality is a lot of fun, but it’s still missing the natural gesture controls capable with a high-end headset like the Oculus Rift or HTC Vive. Now a new development from Israeli firm EyeSight may help bridge the gap with a clever solution.

EyeSight’s new Gesture Control technology uses your smartphone’s built-in camera to track gestures, so you don’t need any extra hardware. However, there are some limits on what it’s capable of. In the demo above you’re limited to a simple tap gesture similar to what Microsoft’s HoloLens can do. The company doesn’t say if it’s capable of tracking more complex gestures.

Once EyeSight’s new software launches it should work on any phone-based VR rig. That includes Samsung’s Gear VR, LG’s 360 VR or any Google Cardboard headset. However, you’ll probably want something with a strap so you don’t have to hold the headset in place with one hand while making gestures with the other.
