ABSTRACT:
A mean distribution of viewer looking time for a group of individuals each viewing a dynamic audio and visual video program measures the mean attention span corresponding to each distinct audio and video component of the overall program. The video program is recorded in measured sequential scenes, with each scene corresponding to a selected audio or visual signal and being comprised of distinct visual areas of interest. Eye point of gaze data is recorded for the duration of the program for each individual viewer in the group. A compiled eye point of gaze data file is compared with a scene by scene data file to produce a third data file showing a mean distribution of viewer looking time for each selected audio and visual signal.
