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We solicit original, unpublished research papers that focus on efforts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:
* -NEW- Crowdsourcing
* 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


We invite two kinds of papers (preliminary abstracts due 8 March 2013):
* full-length research papers, up to 8 pages
* short research papers, up to 4 pages

All accepted papers, whether full or short, should be complete
archival contributions. Contributions from full papers are more
extensive than those from short papers. Preliminary research should be
submitted to the Showpieces category (below). All submissions will be
reviewed by members of the Program Committee. Submission and reviews
for the technical program are managed with EasyChair at:

Accepted papers will be distributed at the conference and will appear
in the IEEE Xplore Digital Library. In 2011 the conference paper
format was changed by IEEE, so be sure you are using the new format,
which is available at:

NOTE: The abstracts due on 8 March do not need to be the final abstract
of the paper. It simply needs to give an informal idea of the paper

=== A Note on Evaluation of Papers ===
Research papers are expected to support their claims with appropriate
evidence. For example, a paper that claims to improve programmer
productivity is expected to demonstrate improved productivity; a paper
that claims to be easier to use should demonstrate increased ease of
use. However, not all claims necessarily need to be supported with
empirical evidence or studies with people. A paper that claims to make
something feasible that was clearly infeasible might substantiate its
claim through the existence of a prototype. Moreover, there are many
alternatives to empirical evidence, including analytical methods or
formal arguments. We encourage authors to think carefully about what
claims their submission makes and what evidence would support them.



Workshops are small meetings intended to foster discussion in an area
related to that of the conference. We strongly recommend that
organizers plan their workshop to encourage interaction among the
attendees and avoid structuring the workshop as a long series of
individual paper presentations. Note also that workshops are not
courses where an instructor teaches the attendees (see Tutorials below
for this).

Prospective workshop organizers must submit a workshop proposal
package, which will be reviewed by the workshop chair and other
conference organizers, and may either be accepted or rejected. If the
workshop is accepted, then both the conference organizers and the
workshop organizers will publicize the workshop to encourage attendees
to submit position papers to the workshop.
The workshop proposal
package must contain:

1. A summary sheet for the proposal that lists
   a) the title of the workshop
   b) the names, contact information for all organizers (one organizer
      should be highlighted as the contact for the workshop chairs)
   c) the organizers' backgrounds
   d) the URL to a preliminary workshop web page (this page need not
      be final at submission time but should provide current status
      information if accepted).
2. A description of the topic and rationale for the workshop,
   including a brief description of why the workshop will be relevant
   to VL/HCC 2013 attendees

3. A detailed plan for carrying out the workshop, including
   a) the method for soliciting position papers from potential attendees
   b) the method for selecting attendees from submitted position papers
   c) an approximate schedule for the workshop
   d) a brief description of any post-workshop activities (e.g.
      curating a journal special issue).

4. A Call for Participation document (500 words or less) that can
   be used to advertise the workshop on mailing lists, the VL/HCC
   web site, etc.

The proposal package must be submitted as 4 PDF files by e-mail to the
workshop chair, Mary Beth Rosson <> by Friday, March 1,



Tutorials allow conference attendees to expand their knowledge.
Tutorials might introduce researchers to emerging areas or new
technologies, or provide an overview of the state of the art in an
existing research area. Prospective tutorial instructors must submit
a tutorial proposal package, which will be reviewed by the tutorial
chair and other conference organizers, and may either be accepted or
rejected. If the tutorial is accepted, then both the conference
organizers and the tutorial instructors will publicize the tutorial to
encourage attendees to register for the tutorial. The tutorial
package must contain:

1. A course abstract of at most 500 words that lists
   a) title
   b) instructor(s) name and affiliation
   c) course duration
   d) a description of the benefits that attendees will receive from
      this course, the features of the course, and background on the
   Feel free to use bulleted lists in the abstract as needed.
   abstract will be used to advertise the tutorial if it is accepted.
2. A course description of 1–4 pages. This should contain
         a) proposed duration of the tutorial (half day or full day,
      though shorter tutorials could also be proposed)
   b) learning objectives
   c) justification: Why will this tutorial be of interest to the
      VL/HCC 2013 community?
   d) content: Describe in detail the material that will be covered.
   e) presentation format and schedule: Describe in detail the
      format of the presentation and how it will be organized.
   f) tutorial history: Describe the history of the tutorial, if any.
   g) audio/visual needs: Describe any technology that you will need
   in order to present your tutorial. We should be able to provide a
   projector, screen, and some form of computer audio system. Be sure
   to mention any needs beyond that set of equipment.

The proposal package should be submitted as two PDF files via e-mail
to the tutorial chair, Mary Beth Rosson <>, by Friday,
March 1, 2013.


Showpieces offer an interactive opportunity to show off your ideas
and/or accomplishments to the VL/HCC community. Formerly called
"posters and demonstrations," the category has expanded in 2013 to
also include videos, downloadable apps, handouts, electronic devices,
physical prototypes, or any other artifacts that facilitate meaningful
interactions with with other conference attendees. The deadline for
submissions is June 7. More information is on the VL/HCC 2013 web site


The conference will also hold a single-day graduate consortium for
graduate students about their research, and it will have conference
and travel funding for accepted students. Students are encouraged to
submit papers to the main conference as well as to apply to the
consortium. The deadline for submissions is June 7. You can read more
