The system is able to capture the driver’s eye gaze and eye vergence to trigger information on a transparent display or HUD. By using eye contact, eye gestures, and simply focusing on the area of interest, the driver is able to interact intuitively with the car without using his hands or voice.
I designed and built this system including the projection based transparent display, interface, interaction method and vergence detection using a standard Tobii Eye Gaze tracking device
I also created a video showing the UX of this system.
