Scope

The Ubiquitous Computing paradigm has the potential of drastically changing the way in which users interact with computers by providing (virtually) ubiquitous access to services and applications through a large number of cooperating devices. However, in order to make this vision come true and to realize a consistent and easy-to-use interface a number of (new) challenges have to be met, e.g.

shared use of multiple services by multiple users using multiple devices
spatial, temporal and conceptual consistency of user interfaces
new 'devices' such as tags or everywhere displays
new UI paradigms such as tangible, physical and hybrid UIs
new UI metaphors for bridging the physical and virtual world
larger and 3-dimensional space of interaction
spatial and temporal mappings between real and virtual world
dynamic set of devices (i.e. people moving in and out)
dynamic adaptation among several dimensions: devices, users, services
restrictions of technical resources in the environment
restrictions of cognitive resources of users
presentation planning for single users vs. groups
virtual characters as moderators, mediators and/or contact personas
tracking and modeling social behavior and protocols

While there are already a number of ubiquitous user interfaces out there, last year's MU3I workshop helped us to identify several central problems that need further investigation. One major issue is the consistency of an interface across multiple devices: How can we build interfaces, which span multiple devices so that the user knows that they can be used to control a specific application? How do we avoid information overload, interference and ambiguity? How do we best guide attention from one device to another when they are used in the context of the same application?

Format

The workshop will be held as as a half day event, and we plan to bring together 15-20 people with a strong interest in one or more of the above named areas. Unlike last year's workshop, MU3I 2005 will be mainly focussed on discussion rather than on technical presentations. All accepted papers will be published on the workshop web site in order to enable participants to read all submissions prior to the workshop. The workshop itself will combine discussion in small break-out groups and plenary discussions. The expected outcome is an initial research agenda to address the question of consistency in ubiquitous user interfaces.

Prospective participants are invited to submit position papers of up to two pages length, which outline one or more potential topics/solutions to discuss during the workshop. Papers should be formatted according to CHI format (there are also latex style files). Submissions should be sent to andreas.butz@ifi.lmu.de or kray [at] comp.lancs.ac.uk no later than November 8, 2004. They should include the name and address of the primary contact and the paper as a PDF file. Notification of acceptance will be mailed to the contact author by November 29, 2004.

All workshop participants will have to register for the main conference (IUI'05) in order to attend MU3I.
