Reach-Through-the-Screen: a new metaphor for remote collaboration

摘要: For some years, our group at FX Palo Alto Laboratory has been developing technologies to support meeting recording, collaboration, and videoconferencing. This paper presents several systems that use video as an active interface, allowing remote devices information be accessed “through the screen.” example, SPEC enables collaborative automatic camera control through window. The NoteLook system allows a user grab image from computer display, annotate it with digital ink, then drag or different display. ePIC facilitates natural of multi-display multi-device presentation spaces, while iLight users “draw” light on local object. All serve platforms for researching more sophisticated algorithms additional functionality ease use.
