Abstract: Heartrate tracking is performed entirely optically without the subject being required to wear any monitoring equipment by processing a combination of signals representing frames of video of the sinusoidal motion of a subject's facial skin color changes captured by both IR and visible light (e.g., RGB—red/green/blue) cameras. The IR and RGB graphs that result from the processing are perfectly phase-shifted so that when the IR signal is going down in amplitude, the RGB signal is going up. Such phase-shifting enables the optical heartrate tracking to utilize diverse input feeds so that a tracked signal is accepted as the user's true heartrate when both IR and RGB signals are well correlated.

Abstract: Embodiments of the present invention provide an audience-aware advertising that are advertisements coordinated with both a present media presentation and the media presentation's current audience. An audience-aware advertising pod is a container for advertising content that is shown in association with a media presentation. The audience-aware advertising pod may include multiple advertisements shown during a commercial break in the primary content. The advertisements may be selected for display within a media presentation in real time based on audience members' attention level and response. Audience profiles may be generated and stored locally. The audience profile may be used to determine when an ad is displayed and what advertisement is displayed.
