Bring your PowerPoint file on a flash drive to avoid switching from the main presentation laptop to the individual laptop of each speaker. Prior to your session, and as early as possible — first in the morning or during lunch — have the session assistant load your presentation on the computer from your flash drive and test it to ensure that it functions properly. At the end of each session, all presentations will be deleted from the computer, ensuring that your presentation cannot be used by anyone else.

Microsoft PowerPoint is the software used for presentations. A slide ratio of 4:3 is recommended. Should your presentation be in another format, please test it out on a PC using PowerPoint to make sure that it will be compatible with the on-site PC, and bring a backup copy in PDF format. If the presentation has been prepared in PowerPoint for Mac, this is rarely a problem.
We recommend you use the PC provided in the conference room. If you do need to use your own PC, you will need to connect it to a projector in the conference room using a USB connection and the system provided. We ask you to be considerate of the presenter following you and to make sure your technical setup does not take away from any of their presentation time. So, please test that your own device works with the projector prior to your session. If you have movies with sounds in your presentation, please contact us before the conference.
Most oral presentations are scheduled for 15-minute time slots: 12 minutes for presentation plus 3 minutes for questions. Invited talks are for 20 minutes with 17 minutes for presentation and 3 minutes for questions. Time limits will be strictly enforced by the session moderator, who will warn each speaker when they are approaching their time limit. A laser pointer will be provided.

If for any reason you are unable to present, please inform the POF2023 Secretariat by email at This email address is being protected from spambots. You need JavaScript enabled to view it.. Notify the Chairperson of your session as well. If you can’t attend the meeting, your co-author may present.
