Abstract

This paper presents a low-cost, wearable headset for 3D Point of Gaze (PoG) estimation in assistive applications. The device consists of an eye tracking camera and forward facing RGB-D scene camera which, together, provide an estimate of the user gaze vector and its intersection with a 3D point in space. The resulting system is able to compute the 3D PoG in real-time using inexpensive and readily available hardware components.
