Abstract: A method of dynamically pacing the presentation of pre-recorded supplementary content to synchronize to live content at a live event, comprising providing the pre-recorded supplementary content associated with the event to end-user devices, with an ordered sequence of content items, each timed to be played on the end-user devices sequentially according to a predefined presentation time duration, and each associated with a scripted property, receiving real-time sensor data from sensors in a facility measuring a property of the live event, matching the measured property of the live event with a corresponding scripted property to identify a live progress of the event indicated by a progress indicator, and sending the indicator to the end-user devices to synchronize the timing of the measured properties of the live event with the timing of the content item associated with the matching scripted property.

Abstract: A multi-layer sticker is provided herein. The multi-layer sticker may include: a first attachment layer; an electronic circuitry layer comprising an electronic circuit suitable for connecting to a consumer electronics device, wherein the electronic circuitry layer is attached on one side to the first attachment layer; a second attachment layer coupled to first attachment layer; and an interface electrically coupled to the electronic circuit and configured to establish an electronic connection with the consumer electronics device.
