[Paper] Eye-Position Distribution Depending on Head Orientation when Observing Movies on Ultrahigh-Definition Television

抄録

We investigated the relationship between eye-position distribution and head-orientation while viewing dynamic images in an 85 inch 8K ultrahigh-definition television (UHDTV). Participants watched video clips of several types of scenes made for UHDTV without any restriction of head movements. The result showed a correlation between eye and head orientation, which is similar to the coordinative movements of the eye and head for static-image viewing in previous studies. The distribution of eye positions was biased in the direction of head orientation both in horizontal and vertical directions. When the head orientated to the left/right (or up/down), the eyes also tended to direct in the left/right (or up/down) relative to the head. These findings suggest that eye-head coordination is similar between static and dynamic images and that head orientation could be used to evaluate the viewing condition and image contents of wide field of view display such as that of an UHDTV.
