Reach-Through-the-Screen: A New Metaphor for Remote Collaboration


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 and information
to be accessed “through the screen.” For example, SPEC enables collaborative
and automatic camera control through an active video window.
The NoteLook system allows a user to grab an image from a computer
display, annotate it with digital ink, then drag it to that or a different
display. The ePIC system facilitates natural control of multi-display and
multi-device presentation spaces, while the iLight system allows remote
users to “draw” with light on a local object. All our systems serve as
platforms for researching more sophisticated algorithms to support additional
functionality and ease of use.
