three-dimensional recovery of gaze for the modeling of attention in natural environments

Lucas Paletta, Joanneum Research, Austria

The talk will describe the localisation of human gaze with respect to indoor environments, without the need of artificial landmarks in the field of view, and the accumulation of dwell times on the modeled environment for the definition of 3D heat mapping. In contrast to previous work, the presented methodology enables mapping of fixations directly onto an automatically computed 3D model of the environment. The user’s view is gathered with wearable eye tracking glasses and localized through the matching of descriptor features in the field of view. In the same line of technical development, recent work on the recovery of 3D gaze on mobile displays will be presented. The capability to automatically recover3D gaze in large studies is a starting point for research questions to investigate spatiotemporal attention in interaction with the environment.
