Preparing and delivering an effective and informative presentation at the meeting is absolutely essential. The following guidelines and forms will be helpful as you prepare for your oral presentation at the conference. Please note the list of audio-visual equipment which will be available for your use at the conference. If you require any other equipment, you must advise us well in advance. Note that you may be responsible for the additional cost (e.g., in case of unavailable equipment). We will try to accommodate your needs without extra cost to you, but special orders may not be coverable and may be charged directly to you. Please check with us on availability and prices for extra equipment or support.


Good visual aids can greatly enhance the effect your presentation has on the audience. Experience at past conferences has shown that many of the oral presentations have not been adequately prepared always. Often an attempt was made to present too much material and too much detail that will go overtime. Or underprepare and have a much shorter presentation with incomplete content and insufficient details. Good presentation means using the allocated time fully, effectively and efficiently. Audio and visual aids, the primary means to hold the attention of the audience, were often poorly conceived and inadequately prepared. It is our hope that these guidelines will help you prepare a better visual presentation.

Most sessions run 100 minutes without a break and typically include four papers. Unless otherwise noted, this allows for introductions and then about 24 minutes per paper, of which about 3 minutes should be reserved for audience questions and comments.

REMEMBER, your entire paper is published in the Proceedings and on the CD-ROM. Your objective in the oral presentation should be to describe the highlights of your paper, progress since the paper was written, and future plans. DO NOT try to present the paper in its entirety, and do not read it!

There are many more detailed resources available on how to put together a well prepared technical presentation. Presenters are urged to look into them, whether at libraries or online.



The most significant constraint facing the speaker is the time limit for presentation. As described above, presentations are nominally allotted 20-25 minutes unless otherwise noted.

This time limit also restricts the number of concepts or major technical points that can be made by the speaker and absorbed by the audience. As a guideline, it is suggested that a presentation cover no more than 10 technical points. Logically linked by the theme of the paper, each of these technical points can be expressed as a declarative statement, substantiated with supporting material. Though the selection of no more than 10 significant points may seem like a great hardship, it will enhance the audience appreciation of a paper by focusing on the most significant information.


The best way to present material in a limited time period is to use well-conceived audio and visual aids that support each of the points to be made. As a first approximation, the speaker should plan for overhead slides or ”VIEWING FRAMES” for each of the 10 main technical points to be presented. All rooms will be set up for overhead computer projected presentations with adequate audio support. Any additional or specific audio-visual requirements must be arranged with HPCS organizers prior to the conference.

Good sound and visual aids significantly simplify the presentation task. They simultaneously focus the audience attention and provide cues for the speaker. The speaker should plan to speak about all of the material on a slide (or it shouldn’t be there) before amplifying a single item.

In general, include no more than six supporting concepts on each slide presenting one technical point. If there are more, simply select the most pertinent. Remember once again, visual aids are not a complete reconstruction of the manuscript. The full story appears in the Proceedings manuscript and visual aids are only attention-focusing cues for the most interesting highlights.


A speaker can expect to speak about SIX sentences per slide, which normally runs about 120 words or 1 to 1.5 spoken minutes. Since a speaker will have ten slides, the basic presentation will run about 15 minutes. This allows additional 5-10 minutes to title, identify, and summarize the basic material, recognizing that audience receptiveness peaks at the beginning and conclusion of each talk. Therefore, a total of 15-20 slides will be more than adequate normally when paced correctly.

It is essential that the presenter uses all the time allotted to them, not shorter and not longer. Have a dry run to ensure good presentation and timing.


The primary advantage for the speaker who organizes her presentation in this manner is that she can approach the audience with the assurance that she can easily and effectively present the salient points in her paper in an effective and clear way.

Since the speaker is cued by her slides, and since she certainly can speak to any of the technical points she has selected for at least one minute, the speaker no longer needs a written speech or even prepared notes. Thus, a measure of spontaneity can enter the technical presentations. Coming well prepared makes things go much easier.

Another important aspect is to make sure you present the work very clearly, accurately and succinctly. Your voice should be at the correct level so that all attendees can hear you well, loud and clear. Check with the audience if they can hear you. Eye contact with audience is important as well.


The Session Chairperson makes the final decisions regarding timing of presentations, subject to the constraint that all papers in the session must be completed within the time allotted equitably. Any deviations from these guidelines should be approved by the Session Chair(s) and Conference Program Chair(s).

SPEAKER'S Meet & Greet

On the morning of your presentation, a Speaker's Meet & Greet session will be held for you to meet with your Session Chair and Co-Presenters. This meeting is very useful and strongly encouraged. Please do your best to attend it.


It is absolutely critical that each accepted paper be presented at the conference in the best possible way as scheduled. Poor presentations will not count. The conference reserves the right to consider such poorly presented papers as 'not presented' and treat the paper as a no-show.
