This is Eye Tracking
Eye tracking is sensory technology that enables a device to know exactly where your eyes are focused. It determines your presence, attention, focus, drowsiness, consciousness and other mental states. This information can be used to gain deep insights into consumer behavior, or to design revolutionary new user interfaces across various devices.
We are very excited to be collaborating with Tobii to offer an entirely new gaming experience. “Overnight” will be fully compatible with the Tobii Eye Tracker and will make for a highly interactive gaming experience.
