Abstract: A basic objective of Weiser's Ubiquitous Computing
vision is ubiquitous information access: being able to utilize
any content (e.g., all the rich media content and services on
the WWW), using devices that are always "at hand" (embedded
in environments or portable), over a network with universal coverage
and adequate bandwidth. Although much progress has been made,
the ideal remains elusive. This talk examines some of the inter-relations
among three dimensions of ubiquitous information systems: (1)
ubiquitous content; (2) ubiquitous devices; and (3) ubiquitous
networking. We use the space defined by these dimensions to reflect
on some of the tradeoffs designers make, and to frame our discussion
of M-Links (mobile links), a new system that takes aim at the
elusive ideal of ubiquitous information. Based on our earlier
experiences building and using a Web browser for small devices
(Digestor) M-Links proposes a new UI that splits apart the integrated
activities of link following and reading into separate modes:
navigating to; and acting on web content. This interaction technique
for very small
devices is both simpler for navigating and allows users to
do more than just read. The M-Links system incorporates modal
browsing interaction and addresses a number of associated problems.

Jonathan Trevor is a Research Scientist at FX Palo Alto Laboratory
(FXPAL) working in the area of computer-based cooperative work.
For his Ph.D. at the CSCW Research Center, Lancaster University,
he developed an infrastructures for developing cooperative systems.
While at GMD, Germany, he co-developed "BSCW" - a web-based
shared workspace system that gained the European Software Innovation
Award in 1996. He returned to Lancaster to work on a number of
Europe-wide projects, including "eSCAPE" an electronic
landscape providing interconnections to other virtual environments.
His current research at FXPAL continues within an interdisciplinary
team and focuses on the development of readily accessible groupware
and HCI applications across a wide-range of technologies and
platforms.
David Hilbert is a Research Scientist at FX Palo Alto Laboratory
(FXPAL) working in the area of personal and mobile computing.
His research interests lie in the overlap between software engineering
and human-computer interaction. His Ph.D. work at U.C. Irvine
explored techniques for capturing application usage data on a
large scale to help improve the fit between application design
and use. Before joining FXPAL, he also worked as a software engineer
at NASA's Jet Propulsion Laboratory and (for a short time) as
a program manager at Microsoft.
