Developers may already be familiar with Clay, it’s an SDK that allows smartphone apps to track the user’s hand in 3D with just the phone’s camera. It can recognize more than 30 gestures users make with their hands, allowing for controller-free navigation of experiences.
After Apple introduced ARKit to the world last month the Clay team set about integrating functionality into the SDK, and the company tells us that it will be ready within the next week or two.
