Abstract: In some aspects, a method of authoring an interactive presentation includes defining a sequence of two or more primary content items within a presentation, and associating a link to additional content with a primary content item of the sequence in a non-transitory computer-readable medium. In additional aspects, a method of delivering an interactive presentation includes accessing the sequence of two or more primary content items, delivering the primary content items to a presentation device, and delivering, to applications operating on mobile devices of audience members, the primary content items with the additional content and/or one or more links thereto. In further aspects, a method of interacting with an interactive presentation includes receiving, by a mobile device of an audience member, a sequence of primary content items with additional content and/or one or more links thereto, and displaying the received primary content items and the additional content.

Abstract: Method and system for reporting events stored in an event log of an electronic device to requesting remote computers. An event reporting mechanism within the electronic device inserts special watermark events into the event log in order to keep track of particular reporting threads. The reporting thread may be associated with a particular type of logged event and a particular requesting remote computer. Watermark events allow logged events to be reported without duplication and with minimal chance of omission. Implementation of the watermark-based event reporting technique does not require extensive changes to, or reformatting of, non-volatile memory-based events logs, and only minimal changes to the hardware circuitry or firmware that implements the event reporting mechanism within an electronic device.
