Most technological advances can make existing activities easier, faster, more accurate and more economical. Some lead to the creation of completely new activities. These technologies benefit people by helping them work more effectively and work more comfortably by creating new leisure activities and by opening new ways for communicating with friends, family, and colleagues.

The demonstrations track of CHI 2003 is looking for examples of technologies with such potential. We encourage demonstrations of new and emerging technologies as well as innovations of current technologies.

We are interested in demonstrations of all technologies on the full range of HCI related topics especially as they relate to the conference theme and special areas (E-learning, Emotion and Mass Communication).

Examples of areas of interest include:

• ubiquitous computing
• wearable and implantable computers
• universal usability/accessibility
• augmented reality
• multimodality
• groupware
• non-traditional input and output techniques
• information access and visualization

There are two types of demonstrations: formal and walk-in.

Formal Demonstration Presentations

A Formal Demonstration Presentation is a 30-minute live presentation or video presentation of a running system, a technique, or a methodology to an audience. Demonstrations offer an opportunity to show the CHI audience an innovative:

• interface concept
• HCI system
• technique or methodology

The first two categories typically demonstrate running systems or prototypes. The third category includes, but is not limited to, techniques for designing, prototyping, developing and testing the usability of computer interfaces. In all cases, the demonstration should present the technology's potential for discovering and crossing new horizons in HCI. We also remind you that audience participation enhances almost any demonstration.

Walk-In Demonstrations

Walk-In Demonstrations do not require technical submissions, do not appear in conference publications, and do not receive specialized audio-visual or computing support. Walk-in demonstrations typically are used for sharing work with other members of the HCI community on an informal basis. During the conference, standard facilities for walk-in demonstrations may be reserved for 45-minute time slots.

An international panel will review the Formal Demonstration Presentations submissions for quality and interest to the CHI audience. Both thetechnicalcontent and presentation potential will be reviewed. Demonstrations thatarejudged to have little or no technical merit or that appear to beadvertisementswill not be accepted.

Review criteria include:

• contribution to the field of HCI
• originality of the work
• proper referencing of research or practical claims, and of closely related work
• maturity of the concept, system, tool or technique
• quality of presentation

CHI 2003 provides mentors for proposers who would like assistance in preparing their submissions. Please see the mentoring program for more information. The deadline to request a mentor is 7 June 2002.

Walk-In Demonstrations require no formal submission. The following only applies to Formal Demonstration Presentations.

Formal Demonstration Presentations are refereed and therefore require technical submissions, appear in conference publications, and are presented in scheduled sessions at the conference. A refereed demonstration interweaves an explanation of technical approaches with a live demo. Sample demonstration proposals will be available.

Submission Format

A Formal Demonstration Presentation submission consists of three parts:

• an extended abstract
• a proposal
• a script outline

Extended Abstract
Prepare a two-page paper in the Conference Publications Format suitable for publication in the CHI 2003 Extended Abstracts, including title, author information, abstract, keywords, body, and references. Since it will bereadby people who may not view the demonstration, it must be understandable on its own.

Proposal
A demonstration proposal contains:

• a statement of why this is an appropriate format in which to present the work
• a description of the system and problem(s) it addresses (if appropriate)
• a description of the relevance of the work to the HCI community, emphasizing its novelty, uniqueness, and rationale
• a statement about the commercial status of the technology
• a description of who the presenter is (developer, designer, marketer, etc.)
• a detailed description of the necessary audio-visual and computing support
• a URL to any video material associated with the demonstration

Script Outline
A script outline of the demonstration describes the flow of presentation. Begin with a statement of the problem being addressed. Then outline the sequence of the demonstration or video, narrative, and audience participation. Include screen shots, snapshots, or sketches (as appropriate) and the narrative used to weave the demonstration together. Plan to use at least two-thirds of your time for the demonstration or video rather than giving a talk.

Confidentiality of submissions is maintained during the review process.All submitted materials will be kept confidential until the date of theconference.

Requirements for Formal Demonstration Submissions

• Your submission must be in English.
• Your submission must be a single PDF file containing the Extended Abstract (2 pages), proposal and script outline.
• Submissions will not be accepted by fax.
• Submissions arriving after the deadline will not be considered.
• Your submission should contain no proprietary or confidential material and should cite no proprietary or confidentialpublications.
• Responsibility for permissions to use video, audio, or pictures of identifiable people rests with you, not CHI 2003.
• You will receive email notification upon receipt of your submission.

Submissions must be in English and must be received before the deadline of 23 September 2002 at 5PM (17:00) your local time. Submissions arriving after the deadline will not be considered. Send your PDF file to chi2003-demos@acm.org. If you anticipate difficulties with emailing a single PDF file, please contact us well before the submission deadline.

Extended abstracts of accepted demonstrations will be published in the CHI2003 Extended Abstracts.

Authors will receive an email notification of acceptance or rejectionby November 11th, 2002. Upon acceptance you must complete and return acopyright release form in order to be published. This form will be sent with the acceptance notice.

The primary author of each paper will receive instructions on how to submit publication-ready copy. Only minor corrections to the original submission will be possible at this stage. Therefore, ensure that your original submission is clearly written, carefully proofread, and correctly formatted. The publication-ready copy and the copyright release are due by January 17, 2003.

Conference attendees who wish to make a Walk-In Demonstration may sign during the conference to reserve standard facilities for 45-minute time slots.

Authors of accepted Formal Demonstration Presentations will presenttheir work in a scheduled session. Presentations are generally 30 minutes, with a 20-minute demonstration and 10 minutes for questions. Demonstrations are provided with computer support and/or video projection support. Audio-visual support and large-screen projection are also provided. Presenters of Formal Demonstration Presentations that use computers must provide their own technical support and are required to perform a technical rehearsal in the demonstration preparation room well in advance of their presentations. We encourage presenters to present videos of their system instead of performing a live demonstration that may be prone to unpredictable system problems.
