Abstract: An attention manager presents information to a person in the vicinity of a display device in a manner that engages at least the peripheral attention of the person. The information is embodied by one or more sets of content data (e.g., video or audio data). Each set of content data is formulated by a content provider and made available for use by content display systems. Upon appropriate activation, each content display system displays images corresponding to the sets of content data in accordance with predetermined scheduling information. The attention manager makes use of “unused capacity” of the display device and the person's attention, providing information to the person that the person might not otherwise expend adequate energy to obtain.
