Demonstrations

Demonstrations offer an opportunity to show the CHI audience an innovative:

• interface concept
• HCI system
• technique or methodology

Sample Demonstration Proposals are available as examples.

Types of Demonstrations
A demonstration may either be a live demo or a video demo. A live demo is a live presentation of a running system, a technique or a methodology to an audience with an accompanying talk. A video demo interweaves explanation of technical approaches with a video tape showing a system, technique or methodology.

We would like to encourage demonstrations which go beyond the desktop, e.g. new interactive devices, and demonstrations which facilitate group interaction, in order to let participants to the conference experience what the future of HCI will bring.

Demonstrations Format
CHI 2000 will include both walk-in demonstrations and refereed demonstrations. Apart from the following paragraph, all text in this section refers to refereed demonstrations only.

Walk-In Demonstrations
Walk-in demonstrations (live or video) 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 scheduled for 45 minute time slots. The CHI 2000 Advance Program will provide details for Walk-In Demonstrations available here after November 1999.

Refereed Demonstrations
Refereed demonstrations (live or video) require technical submissions, appear in conference publications, and are presented in formal sessions at the conference. A refereed demonstration interweaves explanation of technical approaches with either a live demo or a video demo.

Review Criteria
Refereed demonstration submissions will be reviewed for both technical content and presentation. Demonstrations that are judged to have little or no technical merit, or that appear to be advertisements, will not be accepted. Review criteria include:

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

Submission Format
A refereed demonstration submission consists of three or four parts, depending on the type:

• an extended abstract (paper version and electronic version)
• a proposal
• a script outline
• for a video demo, a high-quality videotape

Extended Abstract
The extended abstract consists of a two-page paper in the Conference Publications Format suitable for publication in the CHI 2000 Extended Abstracts, including title, author information, abstract, keywords, body, and references. Since it may be read by people who have no opportunity to view the demo, it must be understandable on its own. We strongly prefer an additional electronic submission as a PDF file by email to the Send To address shown. This is optional, but will greatly assist the reviewing process. Prepare the electronic version of the extended abstract following the instructions in Electronic submissions.

Proposal
A demonstration proposal contains:

• a statement of why a demonstration is an appropriate format in which to present the work
• 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.

Script Outline
Video demos take 30-minutes time slots, live demos have 45-minute time slots. In both cases, prepare a script outline of the demonstration describing the flow of presentation. Give the reviewers an impression of how the sequence of narrative, demonstration, video presentations, and interaction with the audience will be structured. Begin with a statement of the problem being addressed. Then outline the scenario that will be used to demo the interaction technique, system, or technique, either live or on video. Also, provide the narrative that will accompany the presentations. Include screen shots, snapshots, sketches, or video images as appropriate to the content of the demo. Both types of demos can make use of supporting, additional videotape, but this will not be published. Please note that the emphasis for demos must be on the demonstration part, not on a talk about the system or technique; so plan to use substantially more than half of the time for demonstration rather than giving a talk.

Videotape (for video demos)
For a video demo, prepare a videotape, 2 to 8 minutes in length, suitable for publication in the CHI 2000 Video Program. Be sure to read our Guide to Successful Video Submissions and consult Video Submissions for details about how to submit a video. Please note that while the submitted tape is published, you should show much more than this during the presentation.

Upon Acceptance
Authors will be notified of acceptance or rejection by 7 November 1999. Extended abstracts of accepted demonstrations (both live and video) will be published in the CHI 2000 Extended Abstracts. Videos of accepted video demos will be published in the CHI 2000 Video Program. The primary author of each accepted demonstration will receive an Author Kit with detailed instructions on how to submit camera-ready materials for publication. These materials are due by 13 December 1999.

At the Conference
Authors of accepted refereed demonstrations will present their work lecture style, within 45 minutes for live demos and 30 minutes for video demos, including time for questions. Refereed demonstrations are provided with computer support and/or video projection support. Audio-visual support and large-screen projection are also provided. For live demos that use computers, authors must provide their own technical support and are required to perform a technical rehearsal in the demo prep room in advance of their presentations. Some demonstrations will be allotted additional time for conference attendees to interact with the demo in a small-room setting. Presenters have the option of requesting student volunteers to monitor the demo.
