Expressive 2014 - Call for Papers and Posters
* Computational Aesthetics 2014
* Non-photorealistic Animation and Rendering 2014
* Sketch-based Interfaces and Modeling 2014

Date: August 8 - August 10, 2014
Location: Vancouver, British Columbia

Paper submission deadline: April 21, 2014
Poster submission deadline: June 6, 2014

Expressive 2014 is a joint symposium that includes Computational Aesthetics
(CAe), Non-Photorealistic Animation and Rendering (NPAR), and Sketch-Based
Interfaces and Modelling (SBIM). It will be co-located with SIGGRAPH and
will take place in Vancouver, BC, August 8-10, 2014. A single registration
for Expressive 2014 will include all three symposia.
Invited talks and artists talks will be shared among the conferences, and
sessions will be mixed. Participants will be able to freely switch between
the sessions, so as to see the talks of their own field of work and also be
inspired by talks from related domains. The submission, review, and
publication process for the event will be handled jointly across the three
conferences. Each paper submission should be designated as belonging to one
of the three tracks.

***Computational Aesthetics

Computational Aesthetics (CAe) bridges the analytic and synthetic by
integrating aspects of computer science, philosophy, psychology, and the
fine, applied & performing arts. It seeks to facilitate both the analysis
and the augmentation of creative behaviors. CAe also investigates the
creation of tools that can enhance the expressive power of the fine and
applied arts and furthers our understanding of aesthetic evaluation,
perception, and meaning. The Computational Aesthetics conference brings
together individuals with technical experience of developing computer-based
tools to solve aesthetic problems and people with artistic/design
backgrounds who use these new tools. Refereed CAe papers and artworks aim
to facilitate a dialog between scientists and engineers who are creating
new tools, and also artists and designers who use them. Presentations will
provide a snapshot of the latest technical breakthroughs and the most
recent artistic or design achievements in applying computer-based
techniques to solve aesthetic problems.

Technical submissions are invited across the broad range of areas covered
by Computational Aesthetics. Specific technical areas include, but are not
limited to:
* computational analysis and modeling of creative behavior (AI, A-life)
* artistic image transformation techniques (colors, edges, patterns,
* image style and salience analysis (paintings, photographs, others)
* visualization (perceptual or aesthetics based)
* sketching, simplification techniques (artistic, cognitive)
* composition, visual balance, layout
* non-photorealistic and illustrative rendering addressing computational
* empirically based metrics of aesthetical attributes
* applied visual perception (color appearance, spatial vision, and other
* measuring and describing aesthetics
* computational tools for artists

Successful submissions can, for example, describe novel technical
approaches that address one or more of the areas mentioned above (or
beyond). However, we are equally interested in papers that discuss the use
of existing techniques but combine them in an interesting new way or apply
them in a new context that addresses problems in computational aesthetics.

***Non-Photorealistic Animation and Rendering

Non-Photorealistic Animation and Rendering (NPAR) refers to computational
techniques for visual communication. Such techniques usually generate
imagery and motion which is expressive, rather than photorealistic,
although they may incorporate realistic elements.

We invite researchers, artists, and practitioners of all areas connected to
non-photorealistic animation and rendering to submit papers and posters on
their work. Submitted papers should be self-classified into one of the
following three categories:
* Research: new algorithms, scientific studies, analysis, or data (i.e.,
traditional NPAR papers). These must contain novel results that make a
substantive contribution to the field.
* Production: candid discussion of the process of creating a work (e.g.,
film, image, game) or art tool (e.g., paint or CAD program, software
* Meta: statements about research that do not contain new results, e.g.:
grand challenges, position papers, evaluation standards, surveys, and
primers on art / aesthetics / psychophysics for a computer science audience.

All work must be previously unpublished and contain a novel contribution.
Production and Meta papers need not contain original research or results.

Topic areas of NPAR 2014 include, but are not limited to:
* Expressive character animation and physics
* Abstraction and stylization of images/video
* Interaction techniques
* Accounts of real productions (e.g., animated films)
* NPAR in real software products (e.g., modeling, visualization,
presentation software)
* Visual composition
* Hardware acceleration
* Evaluation methods for NPAR algorithms
* Psychophysics of NPAR
* Rendering and layout for text and presentation graphics
* Quantitative analysis of human artists
* Generative or evolutionary approaches
* Style transfer
* Temporal and spatial coherence
* Adapting classic CG effects like motion blur, depth of field, and
lighting for NPAR
* Simulation of natural media and traditional styles
* Non-traditional camera models
* Position papers on grand challenges

***Sketch-Based Interfaces and Modeling

Advances in pen-based computer hardware have enabled digital sketch-based
interfaces to emerge as a powerful way to combine the quick and intuitive
feel of paper with the power of computation. However, fully realizing the
potential of these sketch-based systems requires effective input devices,
user interface design and underlying algorithms to analyze the input. The
goal of this symposium is to explore models, algorithms and technologies
needed to enable effective sketch-based interfaces. It investigates novel
methods for classification and recognition of hand-drawn shapes, and ways
of using these techniques for creating or editing digital models, text,
mathematics, and 3D shapes. Likewise, the symposium explores the
application of sketch-based interfaces to 3D computer graphics, animation,
CAD, and computer games, as well as other specific applications such as
diagram editing, note taking and novel input devices. Finally, the
symposium welcomes empirical user studies aimed at clarifying the nature of
sketch-based interfaces and comparing them to other interaction techniques.

Created in 2004, SBIM provides a unique venue for researchers, students and
practitioners interested in sketch-based techniques to interact with one
another, share lessons learned, show new results and discuss open issues.

Topic areas for SBIM 2014 include but are not limited to:
* Multimodal interfaces for sketching
* Novel sketch input and editing devices
* Novel pen-based interaction techniques
* Low level ink processing and pen stroke segmentation
* Sketch parsing, classification and recognition
* Sketch-based interfaces for CAD systems
* Sketch-based modeling and editing of 3D shapes
* Sketch-based control of animations
* Sketch-based interfaces for other applications (surface editing, diagram
creation, mathematical annotations, games, etc.)
* Rendering techniques for sketch-based systems (NPR)
* Sketches for Medical and Volume data editing
* Sketch-based retrieval of multimedia information
* Usability studies of sketch-based systems
* Studies of the impact of sketching on creativity and design
* Multi-touch interfaces and applications

***Technical Paper Submissions

Technical papers should present original, unpublished work. There is no
absolute maximum length for paper submissions; please use the SIGGRAPH
length guidelines, found here:
In particular, note that papers longer than 8-10 pages must make a very
significant contribution to be accepted. Manuscripts must be written in
English, and should follow the ACM SIGGRAPH-sponsored conference formatting
instructions (, including
a title page with an abstract and keywords, and a bibliography. The
submission is electronic in PDF format; supplemental video and images may
also be submitted. Research papers are reviewed double-blind and so must be
anonymous when submitted. Information on the submission process will be
available on our website.

Please also note that only PDF files will be accepted for your submission.
Make sure that all fonts are embedded in your PDF file. Additional material
such as additional images or videos may be submitted as PDF or as a zipped
archive (ZIP files) with a maximum size of 30 MB. For videos please ensure
that a commonly available format and codec is used. For example, make sure
that the video plays with VLC, which is available on most platforms.

Accepted papers will be published as a single conference proceedings by ACM
and will be available online via both the ACM Digital Library and the
Eurographics Digital Library. Posters will not be archived. Posters may be
submitted in PDF format as either an extended abstract (1-2 pages) or as a
draft of the poster itself. Rejected papers may be considered for the
poster track.

***Other submission categories

* Presentation of work previously published in a journal: The intent of
this category is to allow authors who prefer (or need) to publish their
work in journal form the opportunity to present that work at Expressive.
These papers will not appear in the Expressive proceedings. Requirements:
The work should be published in the July 2013-Aug 2014 time frame, and not
have been previously presented at a conference or symposium. What to
submit: A copy of the paper abstract and a link to the published paper or a
pre-print of it. Submissions will be reviewed by the program committee for
suitability of content. Note that accepted presentations are subject to the
same rules as regular papers, namely that at least one author must register
for the conference. Deadline: May 7, 2014.

* Technical artwork submissions: All attendees are invited to bring
artworks made using their techniques to show at Expressive (this will be
different from the art show itself). These artworks will be displayed at
the Expressive venue. Requirements: The artwork should be related to recent
technical work that falls under the Expressive umbrella. What to submit: A
one-page abstract describing how the artwork was created, along with an
image or video. Deadline: June 6, 2014.

* Posters, demos, and artwork: You are invited to submit to these programs
any time before June 6; every effort will be made to return a response
within two weeks.
