Abstract
A system to determine viewer attention to presented content. Markers are applied to a presentation. Head orientation information is received from a body mounted camera worn by a viewer and is used to determine a sequence of head orientations of the viewer. The sequence of head orientations is associated with an identifier of the viewer and a corresponding sequence of first time stamps. A sequence of images is captured by the body mounted camera worn by the viewer. The sequence of images is associated with an identifier of the viewer and the body mounted camera and a corresponding sequence of second time stamps. Respective members of the sequences of images and head orientations are associated, and the presentation content is identified by evaluating information from visible markers in the captured sequence of images. Viewer attention to different elements can then be determined.
