Controlled Interactivity - lean-back media experiences based on lean-forward technologies

Presentation at the IFI PhD Seminar Fall 2023, 08.11.23, IFI, UiT The Arctic University of NorwayInteractive rendering technologies like maps, timelines, and plots can be powerful tools for data visualization and exploration. In the context of media, such tools are often referred to as lean-forward, implying that the user is actively telling his own story by using control primitives such as skip, pan, tilt, adjust, scroll, rewind, reorder, zoom, play and more. We are interested in using such lean-forward technologies in the context of broadcasted lean-back experiences, for instance as a secondary for a radio program or a TV show. Importantly, the idea is not to record these experiences as video, as this removes all flexibility and interactivity. Instead, the idea is to let media providers actively remote-control client-side, interactive technologies, as part of production. To this end, we present State Trajectory, a technical concept for shared control state, with built-in support of online sharing, dynamic state changes, and timeline-consistent playback

A programmable structure for pervasive computing

This exstended abstract presents an asymmetric and programmable (extensible) approach to pervasive computing. The idea is to off-load computations from light portable clients into a back-bone of seamlessly integrated servers. This way, a user can extend and personalize his pervasive computational environment by installing computations following his trajectory throughout the day. Focus on this extended abstract is on structural issues related to the back-end servers running mobile code off-loaded from the mobile user
