Spatial setting of visual attention and its appearance in head-movement

摘要

One's "attention" is said to appear in the visual behavior, i.e. eye and head movements and human brain is thought to set visual attention area in the sight to get visual information efficiently. In head-eye coordination head movements are thought to be controlled to fit the sight to visual attention area. Hence, setting of the attention area can appear in head movements. In this study head and eye movements were measured using a wearable head and eye tracker system newly developed in this study, and were studied whether the visual attention could be known from head movements or not. Results show that, head-movements toward new attended area occur when human wants to switch the visual attention.
