VL/HCC 2011
IEEE Symposium on Visual Languages and Human-Centric Computing

September 18-22, 2011
Pittsburgh, PA, USA

From the beginning of the computer age, people have sought easier ways
to learn, express, and understand computational ideas. Whether this
meant moving from punch cards to textual languages, or command lines
to graphical UIs, the quest to make computation easier to express,
manipulate, and understand by a broader group of people is an ongoing
challenge. The IEEE Symposium on Visual Languages and Human-Centric
Computing (VL/HCC) is the premier international forum for research on
this topic. Established in 1984, the mission of the conference is to
support the design, theory, application and evaluation of computing
technologies and languages for programming, modeling and
communicating, which are easier to learn, use, and understand by

We solicit original, unpublished research papers that focus on efforts
to design, formalize, implement, and evaluate computing languages and
development tools that are easier to learn, easier to use, and easier
to understand. This includes languages and tools expressed not only as
text, but through any other means (visual, sketch-based,
gesture-based, or otherwise). This also includes languages and tools
intended for a wide range of audiences, including professional
software developers, novice programmers, or other any other people who
find a need to express computational ideas. We also seek papers that
address cognitive, social, cultural, and theoretical aspects of
efforts to lower barriers to computing.

Areas of interest include, but are not limited to:
* The design, evaluation, and theory of visual languages
* End-user development, end-user programming
* Novel user interfaces for expressing computation
* Human aspects of software development
* Debugging and program understanding
* Computer science education
* Software development tools
* Model-driven development
* Domain-specific languages
* Software visualization
* Query languages

Posters and demonstrations provide an interactive forum in which
authors can present work to conference attendees in the evening. This
venue provides an opportunity to describe new work or work that is
still in progress, and will be more lightly reviewed than papers.
Presentations may include any combination of a poster, video, or live
demonstration. Easels and boards will be available for posters, but
demonstrations and videos should use their personal laptops, as no
supporting equipment will be available from the conference.

Submissions must include a two-page abstract and a brief description
of the planned presentation. The abstract must be written in IEEE
Conference Proceedings format, and describe the research problem,
contribution, and value to VL/HCC attendees. NOTE: This year's
conference format is different from those of previous years, so be
sure you are using the new format. Just like full and short papers,
abstracts will be printed in the proceedings and be included in the
IEEE Xplore Digital Library.

The brief description of the presentation should be submitted as a
separate document, and its contents may vary depending on the type of
presentation. Poster submissions should include a sketch of the
planned poster. Video and demonstration submissions may include a
textual description of the presentation; however, we encourage authors
to also include a preliminary video.

Both the paper and presentation description should be submitted as PDF
files. Submitted video files for posters and demonstrations should be
at most 3 minutes long and 50 MB in size; however, the videos and
demonstrations presented at the conference may be of any length.

Posters should be printed in advance and brought to the conference. We
will provide poster stands with a solid backing and a method of
attaching the posters to the stands. We expect to be able to
accommodate posters of up to 30 inches by 40 inches (either vertical
or horizontal).

Recent advances in computing have led to continually deeper
integration between computers and human society. People now are part
of numerous socio-technical systems that synthesize large numbers of
contributing users with vast amounts of source code. Examples include
social media systems, open source repositories, online marketplaces
and massively multiplayer online games.

Yet as these socio-technical systems have grown in complexity, they
have become increasingly difficult for end users to understand and
direct toward productive ends. For example, when users put data into a
system, they may be unable to anticipate and control how their data
will be used by other people or by software in the system. When users
take actions in the system, they often cannot foresee and manage
unintended effects on other users, software, or the system as a whole,
particularly because the software part of a system often contains

The goal of the 2011 VL/HCC graduate consortium is to explore ways to
help end users visualize, analyze, and tailor large socio-technical
systems. This may include development of novel methods, models and
tools, such as programming environments for end users. At a deeper
level, it may include developing new theory for predicting the
complicated, unstable, sometimes-emergent behavior that results when
large numbers of diverse, unpredictable humans are coupled to
unreliable software.
