Oral Presentation


Here are some general guidelines for presenters at Oral 2019:

Oral Presentation Guidelines

Each timeslot for talks is 15 minutes, so plan on delivering an 10-12 minute talk, leaving 3-5 minutes for questions and switching over between speakers.

All talks should be saved on a USB key and loaded on the laptop present in your lecture room at least 20 minutes prior to the start of your session (loading the day before is encouraged, to give you time to check your slides).

We strongly recommend using Microsoft Office PowerPoint for your presentation. Please note that the congress computers are being supplied with PowerPoint 2013. All presentations will be in a WIDESCREEN format. To take full advantage of the widescreen format, we recommend that you build or convert your presentation to 16:9.

If you intend to use another type of presentation software, or intend to use multiple videos or large media as part of your presentation, please e-mail the secretray (chc2020@conferium.com) at least one week prior to the conference so arrangements can be made.

Please arrive at your presentation at least 20 minutes prior to the start of the session to introduce yourself and work out any technical issues that may exist (including microphones, laser pointers, etc.).

Please respect the chairs if they indicate you are out of time - it is important to keep within defined oral presentation time in order to avoid delays in the sessions.



The lecture room is equipped with microphones, a computer, projectors and screens. Using your own computer will be only allowed in exceptional circumstances: your request must be made the day before at the registration desk and authorized by the organizers. Compatibility test of your equipment will be required. Please note that the time used to switch computer will be deducted from the allotted time.


Important Note for Macintosh Users

In order to use MAC presentations on a PC compatible computer, please note that you need to prepare it according to the instructions below, before bringing it to the lecture Room:

  • Use a common font, such as Arial, Times New Roman, Verdana, etc. (special fonts might be changed to a default font on a PowerPoint based PC).
  • Insert pictures as JPG files (and not TIF, PNG or PICT - these images will not be visible on a PowerPoint based PC).
  • Use a common movie format, such as AVI, MPG and WMV (MOV files from QuickTime will not be visible on a PowerPoint based PC).

You may use your own Macintosh laptop computer as a back-up. In such a case, please make sure to provide a Mini DisplayPort to HDMI or VGA Adapter (Dongle). Please visit the resgirtation desk to check your presentation and advise the staff of your intent to use your own laptop. Please arrive at the lecture room at least 30 minutes prior to the start of your session to plug in your laptop and check your presentation on the projection system.
