Smartphone-based VR headsets like Google Cardboard and Samsung Gear VR are some of the most affordable ways to experience virtual reality, but they lack the advanced motion-tracking controls of high-end headsets like the Oculus Rift and the HTC Vive. However, if a YouTube video from Israeli gesture control company EyeSight Mobile Technologies is to be believed, that might not always be the case.
The video offers a demo of EyeSight-developed gesture controls for phone-based VR headsets. In it, a subject plays a game that's floating in front of him in augmented reality. The rear-facing camera in the phone that's strapped to his face tracks his finger as he points and "clicks" to control the game.
It'd be a similar trick to EyeSight's existing tech, which brings camera-based gesture controls to TV sets, smart glasses and computers. There's no word from EyeSight on when you should start expecting those sorts of gesture controls to arrive for your VR-ready phone, but with the right development, it could be here sooner than you might think.
