Call for Participation
Workshop on
Visual Interfaces to Geometry
in conjunction with CHI'90
Seattle, Washington, April 1-2, 1990
A two-day workshop on Visual Interfaces to Geometry will be held as part
of the CHI'90 Conference. The objective is to explore and integrate
advanced approaches to the visual representation and interactive
manipulation of geometric information. The primary goals are to
(1) define desirable properties of interfaces to geometric data in
different areas, (2) identify problems in achieving these properties, and
(3) discuss generally applicable approaches to these problems from an
interdisciplinary perspective.
Geometric data are an important resource in many areas: Computer Aided
Engineering (CAE), Geographic Information Systems (GIS), Computer
Graphics, Graphic Arts, Electronic Publishing, etc. Data structures for
their representation, and algorithms for their manipulation, have
received ample attention in the domain of computational geometry, with
the object being an optimal use of computer memory and processing time.
This focus on internal representations and manipulations contrasts with a
lack of emphasis on corresponding external concerns: how can geometric
information be presented and manipulated at the user interface,
optimizing "memory load" and "execution speed" (among other criteria)
for users?
Considerable expertise on various aspects of this question has been
developed in a number of fields; however, little effort has been made to
combine this expertise. The workshop will take a multidisciplinary
approach to the problem of improving the visual presentation and
interactive manipulation of geometric information. It should bring
together approximately fifteen people from Computer Science, Engineering,
Cognitive Science and Linguistics, Geography and Cartography, and other
related areas.
Attendance at the workshop will be by invitation. Individuals wishing to
attend are requested to submit four copies of a short position paper
(500 - 1500 words) to the organizers of the workshop. They should present
their view of issues and approaches to be discussed as well as a brief
summary of their background and interest in the subject. The position
papers of the participants will be distributed with the invitation to the
workshop. The participants will also receive a catalogue of related
researchable questions which has been compiled at a workshop on
"Languages of Spatial Relations", organized by the National Center for
Geographic Information and Analysis, as well as an extended bibliography
on the same topic.
A $50 fee will be collected from each participant to help defray the
costs of coffee breaks and audio-visual equipment.
Important Dates: 4 copies of position paper due by February 1, 1990
