Workshops are a chance for members of a community with common interests to meet in the context of a focused and interactive discussion. If you are working in an emerging area in HCI, consider organizing a workshop. They are an opportunity to move the field forward and build community. CHI workshops might address basic research, applied research, HCI practice, new methodologies, emerging application areas, design innovations, management and organizational issues, or HCI education. Each workshop should generate ideas that give the HCI community a new, organized way of thinking about the topic, or ideas that suggest promising directions for future research. Some workshops result in edited books or special issues of journals; you may consider including this goal in the design of your workshop.

Workshops will be held on Saturday 5th and Sunday 6th April 2008. A workshop may be one or two days in length. Workshops should be scheduled to use 6 working hours per day, with a mid-morning break, a lunch break, and a mid-afternoon break. Workshops typically have 15 to 20 participants. Focused interaction among participants is important, so participants must have informed positions based on prior experience.

There are two types of people involved in workshops: workshop organizers and workshop participants. Workshop organizers submit a workshop proposal to CHI. The proposals are reviewed using CHI processes and procedures and are either accepted or rejected. If a workshop is accepted, the workshop is publicized by both CHI and the workshop organizers.

Workshop participants attend the workshop. If a person is interested in being a workshop participant, they must submit a position paper to the workshop organizers. Position papers are reviewed by the workshop organizers using their own criteria, and workshop organizers decide on the final list of workshop participants. Workshops are only open to people who have had their position paper accepted by the workshop organizers, and who have registered for both the workshop and the CHI conference.

The Workshop proposal must be submitted as a single PDF file via the PCS submission system by 15 June 2007 (5:00PM PDT). Final submission PDFs must be no larger than 4 megabytes large.

The proposal must have the following, four distinct sections, all written with the Extended Abstract format:

1. A proposal
2. An extended abstract
3. A call for participation
4. A cover sheet

These documents should all be in Extended Abstract format and submitted in one file. The combined file must be in PDF format. See below for Submitting a Workshop Proposal.

Part 1. Cover Sheet
Each submission should have a cover sheet giving contact information for the primary workshop organizer. This person will serve as the main point of contact with the Workshop Co-Chairs.

Part 2. Proposal
Prepare a proposal for the Workshops review committee. The proposal should not exceed 3 pages. The proposal must describe the topic, a detailed plan for conducting the workshop (before, during, and after), and the organizers' backgrounds.

Part 3. Extended Abstract
Prepare a description of the workshop using a maximum of four pages, suitable for publication in the CHI 2008 Extended Abstracts. It should contain a summary of the workshop's goals and issues. It must be prepared in the Conference Extended Abstracts Format. Note that this document is the only document from the workshop that will be published at CHI.

Part 4. Call for Participation
Prepare a 250-word Call for Participation suitable for publication on the CHI 2008 web site. It should describe the format and goals of the workshop, the participant selection criteria, requirements for position papers (e.g. page length, topics to address, etc), where these papers should be submitted, and the fact that at least one author of accepted papers needs to register for the workshop and for one day of the conference itself. Workshop fees for participants in 2008 are estimated to be $150 for a one-day workshop and $225 for a two-day workshop.

Organizers are encouraged to develop an external web page with additional information about the workshop for potential participants. For an example, see this CHI 2007 workshop page: orchid.cs.uiuc.edu/HCIandNewMedia.

Review criteria include the workshop's potential for generating stimulating discussions and useful results; the expected community interest level in the topic; the organizers' ability to demonstrate in the proposal a well-organized process and plan for the workshop; and the overall balance of topics in the Workshops program. If multiple submissions are received on the same or similar topics, the organizers may be encouraged to merge them.

Organizers will be notified of acceptance or rejection by 18 July 2007. Organizers of accepted workshops will receive detailed instructions on how to submit the final, publication ready Extended Abstract, which is due on 10 Dec 2007.

Workshop Registration Fees
The workshop registration fee will be waived for two workshop organizers. All other participants will need to pay the workshop participation fee. Workshop fees for participants in 2008 are estimated to be $150 for a one-day workshop and $225 for a two-day workshop. In addition to the workshop fees, workshop attendees are required to register for at least one day of the CHI conference.

Organizer Responsibilities: Before the Conference
Organizers are expected to:

At the workshop, the organizer is responsible for facilitating discussion, maintaining productive interaction, and encouraging participation. The emphasis should be on group discussion, rather than on presentation of individual position papers. Diversity of perspectives should be encouraged.

Organizers will be expected to produce a poster summarizing the results of the workshop for the conference reception/poster session.

Poster board panels are 250 cm tall by 100 cm wide (98" high by 39" wide). Posters will *have* to be printed portrait style and will be hung with molding clay.

We will provide the following A/V equipment: projector, screen, and 1 flip chart. Workshop organizers must bring all of their own office supplies (such as markers, tape, crayons, etc.). Organizers have the latitude to purchase any supplies they need up to $50 (USD) and can seek reimbursement from ACM after the conference. Amounts over the fixed budget require prior written approval from one of the conference chairs.

It is expected that workshop results will be communicated to a larger audience. In addition to the poster the organizers will produce during the conference, each workshop may be asked to produce a report for publication in the SIGCHI Bulletin or a similar venue. We encourage additional avenues of communication, such as organizing an informal Special Interest Group (SIG) at the conference, preparing an edited book or special issues of journals following the conference, or maintaining a web site to network with others who might be interested.
