Gaze Tracing in a Bounded Log-Spherical Space for Artificial Attention Systems

Abstract: Abstract. Human gaze is one of the most important cue for social robotics due to its embedded intention information. Discovering the location or the object that an interlocutor is staring at, gives the machine some insight to perform the correct attentional behaviour. This work presents a fast voxel traversal algorithm for estimating the potential locations that a human is gazing. Given a 3D occupancy map in logspherical coordinates and the gaze vector, we evaluate the regions that are relevant for attention b… Show more
