Presentation Guidelines

Your paper has been assigned as either a lecture or a poster presentation. At OPTIM-ACEMP 2025, papers are scheduled into lecture and poster sessions based on thematic coherence rather than by paper quality. In either case, the full, 6-8 page paper appears in IEEE Xplore, and there is no indication in Xplore as to whether the paper was presented orally or as a poster.

Lecture Presentations

Presentation Time

Presentation time is critical; each paper is allocated 20 minutes for lecture sessions, including time for questions, session-chair introductions, and any setup that is not completed in advance. We recommend that the presentation of your slides take about 15 minutes, leaving 5 minutes for introduction by the session chair and questions from the audience; in any event, your presentation must not exceed 17 minutes.

To achieve appropriate timing, organize your slides around the points you intend to make, using no more than one slide per minute. A reasonable strategy is to allocate about 2 minutes per slide when there are equations or important key points to make, and one minute per slide when the content is less complex. Plan on covering at most 6 points per slide, using 6 to 12 spoken sentences and no more than about two spoken minutes. Be prepared to begin your presentation as soon as the prior presenter has finished; it is important to keep on schedule.

Organization of Ideas

Slides attract and hold attention as well as reinforce what you say — provided you keep them simple and easy to read. Make sure that each of your key points is easy to explain with the aid of the material on your slides. Do not read directly from the slide during your presentation. You should not need to prepare a written speech, although it is often a good idea to prepare the opening and closing sentences in advance. It is very important that you rehearse your presentation in front of an audience before you give your presentation at OPTIM-ACEMP 2025. Presenters must be sufficiently familiar with the material being presented to answer detailed questions from the audience.

Prior to Your Presentation

Come to the room during the break immediately prior to your session and upload your presentation to the computer in the room.

PLEASE bring a short CV with you to help the chair present you to the audience

Equipment Provided

All lecture rooms will be equipped with a computer, a video projector, and a microphone. Each computer will have a USB port; there will be no other equipment available.

Each computer will have a recent version of the Windows OS installed as well as Acrobat Reader software. While PowerPoint will also be provided, presenters may use PDF for their presentations to avoid issues with fonts and other problems. Remember to embed all your fonts into your PDF presentation.

Critical Points

• Make sure your presentation does not run into a problem on the Windows 10 platform if you are a Mac or Linux user.
• If you will be playing video or animated media, make sure it runs on Windows Media Player.
• Embed all the fonts in your presentation. Keep in mind that some of the oral presentations will be given in lecture halls that are quite large. When preparing your slides, make sure that they will be legible for the entire audience (i.e., use fonts of sufficient size).

Dialogue Session Presentation

This type of presentation has two parts: An oral presentation of 3 minutes (pitch or teaser to attract the audience to visit the poster) and a separate poster stand for interaction in the dialogue session space. This presentation mode is recommended for authors that want to showcase and challenge their work to a bigger audience.

Oral Part

• File Format: All oral presenters could provide their presentation in a PowerPoint Format or in PDF format (maximum 3 slides). The presentation should be provided on a (virus-free) USB stick to the chair-assistant who will put the presentation on a laptop that is present at the room. The presentation could be done also without supporting PowerPoint.
• File Name: Your presentation should have as filename, the OPTIM-ACEMP number of your paper followed by the Author Name. (Example: OPTIM25_0139_Anna)
• Timing Arrival: All speakers should come to the presentation room 15 minutes before the session starts. Provide your USB stick with your presentation to the chair-assistant who will help you to upload your presentation.
• Timing Presentation: The Chairman of the session will strictly enforce the time limit. The CV of the presenter is not going to be read in this session.
• Location: The oral part is done at the presentation room mentioned on the program. Make use of the oral presentation to invite the public to visit your poster in the dialogue session space.

Poster Presentations

Dimensions

For your poster, a board will be provided; the board is oriented in a “portrait” format and has dimensions of 90cm wide and 120cm tall (approximately 35in wide and 47in tall. Posters should not be larger than A0 paper size). Push tacks or velcro adhesive will be provided at the conference to mount your poster to the board.

Organizing Your Poster

Poster sessions are a good medium for authors to present papers and meet with interested attendees for in-depth technical discussions.

In addition, attendees find the poster sessions a good way to sample many papers in parallel sessions. Thus it is important that you display your message clearly and noticeably to attract people who might have an interest in your paper.

Your poster should cover the key points of your work. It need not, and should not, attempt to include all the details; you can describe them in person to people who are interested. The ideal poster is designed to attract attention, provide a brief overview of your work, and initiate discussion. Carefully and completely prepare your poster well in advance of the conference. Try tacking up the poster before you leave for the conference to see what it will look like and to make sure that you have all of the necessary pieces.

The title of your poster should appear at the top in CAPITAL letters about 25 mm high. Below the title, place the author(s)’ name(s) and affiliation(s). The flow of your poster should be from the top left to the bottom right. Use arrows to lead your viewer through the poster. Use color for highlighting and to make your poster more attractive. Use pictures, diagrams, cartoons, figures, etc., rather than text wherever possible. Try to state your main result in 6 lines or less, in lettering about 15mm high so that people can read the poster from a distance. The smallest text on your poster should be at least 9 mm high, and the important points should be in a larger size. Use a sans-serif font (such as “cmss” in the Computer Modern family or the “Helvetica” PostScript font) to make the print easier to read from a distance. Make your poster as self-explanatory as possible. This will save your efforts for technical discussions.

Presenting Your Poster

Prepare a short presentation of your paper which you can use to emphasize the highlights of your work in a few minutes. Please put up your poster during the break before your session starts, and take it down immediately after your session ends. Each poster session is 2 hours long; a presenter must be present at your poster during the entirety of the session. If possible, more than one author should attend the session to aid in presentations and discussions, and to provide the presenters with the chance to rest or briefly view other posters.
