Abstract
A system for gaze and gesture detection in unconstrained environments includes a 360-degree (omnidirectional) camera system, one or more depth sensors, and associated memory, processors and programming instructions to determine an object of a human user's attention in the unconstrained environment. The illustrative system may identify the object using eye gaze, gesture detection, and/or speech recognition. The system may generate a saliency map and identify areas of interest. A directionality vector may be projected on the saliency map to find intersecting areas of interest. The system may identify the object of attention once the object of attention is located.
