Eurographics Workshop on Sketch-Based Interfaces and Modeling

Grenoble, France, August 30-31, 2004


4-Sep-04
To continue this year's success the Eurographics Working group on Sketch-based Interfaces and Modeling was created.
We look forward to SBM'05 workshop, to take place before Eurographics'2005 in Dublin next year.
1-Sep-04
The workshop is over. We had 48 participants, twice as many as expected! Thanks to all that participated. The proceedings are now available through the Eurographics Digital Library or in paper form, through the Eurographics bookshop. Photos from the workshop to be available next week. Watch this space.

Modeling systems possessing great functionality now enable us to create very complicated models. However, computers have yet to become usable at the very early stages of design, where pencil and paper still reign. This is because present-day interfaces require designers to leap large conceptual gaps from their mental models of desired objects to the geometric models that formally express their shape. As computer systems become more sophisticated, alternative input modalities and interface technologies are emerging which may form the basis for a new generation of sketching applications supporting what we may call Calligraphic Interfaces. The purpose of this workshop is to explore novel user interfaces sketching models. The workshop will build on work done in recent years on modeling, 2D user interfaces and 3D user interfaces. Work in this area, promising as it is, is still far from complete. The workshop will look at means to improve usability of object design systems (including product-design, character-design, or other application areas) through user-centered design approaches, ranging from personal design assistants to media-rich virtual and augmented environments. One direction will focus on handheld and tablet computers for mobile input, combining pen and speech with retrieval of remote product and geometric data using sketches. Another direction will look at creating technical designs from sketches using novel input techniques in 2D and 3D, exploring multiple sensorial modalities and Intelligent User Interfaces. A third direction will explore the relationship between geometry representation and interaction techniques, especially as a catalyst for new interaction techniques.

Authors are invited to submit technical papers in these or related areas. Topics of interest include, but are not limited to:



Workshop proceedings will be available on-line through the Eurographics Digital Library and will be published in paper book form in the Eurographics Book Series. Authors of accepted papers are requested to send their revised contributions, no longer than 10 pages, in Eurographics Conference Paper Format. You can download the set of LaTEX style files customized for this workshop here. This is the preferred and encouraged format for all contributions, as it ensures the closest thing to correct formatting for publication. If for some reason you cannot use LaTeX, as a last resort you can also use an approximate MS-Word template for the submissions, which you can download in ZIP format. If you used MS-Word for submission, please download the template again, since this has been corrected and changed as of June 25, 2004. Please check the final formatting against the guidelines and example provided in the PDF file here.
Please revise your papers according to reviewers' comments following Eurographics guidelines for formatting and send your revised papers to on or before July 12, 2004. Please be sure to include all source files used to prepare the final submission toghether with the final contribution.
You need also to fill in a copyright assignment form using the PDF model available here, fax it to +49 531 3912103 and send it via surface mail to the EG Publications Board chair (see address on page 2 of the form). Please confirm to us by the July 12 deadline that you have done this.



The workshop will take place just before the Eurographics'04 Conference ( September 1-3, 2004 , Grenoble ) . As such, it will provide a very interesting opportunity for researchers that want to attend / present communications at both events. The workshop will be held in two days, including paper presentation and invited sessions. Participation is open to everyone, not requiring submission of a paper.





The conference will take place in the World Trade Center Congress Area, in the Europole business district, just next to the bus and the TGV train station, and surrounded by many hotels and restaurants. It will be co-located with Eurographics 2004 (please see http://www.eg.org/eg2004 for details).
