Guidelines for speakers OB Congress


All oral presentations should be given in English, Dutch or French language. The language of the presentation should in all cases be the same as the language of the title and the abstract as shown in the programme.
The Organizing Committee of OB strongly recommends English for oral presentations, in order to maximize the international appeal of the meeting.

In all cases, the audiovisual material should be presented in English (slides, movies, ...). No other languages are acceptable.

Technical instructions

Speakers are kindly requested to strictly respect the allocated time to guarantee smooth running of the sessions.

  • A single computerized network running the Windows operating system will be used to manage all slide projections. All presentations will be sent to the assigned meeting room from the central server at the Speakers room, by the technical staff. This procedure ensures efficient management and higher quality of projection. The use of personal laptops for presentations is actively discouraged.
  • Speakers are invited to prepare their presentations in Microsoft PowerPoint either for Windows or Macintosh/Apple.
  • PowerPoint presentations on USB memory stick must be delivered at the Speakers room at least one hour before the start of the session. Preview facilities will be available at the Speakers room.
  • Presentations loaded on a personal laptop must be downloaded and copied at the Speakers room at least two hours before the beginning of the session.
  • Should this be the case, please inform the meeting coordinator in the Speakers room about any particular requests well in advance.

Recommendations for your PowerPoint presentation - format 16:9

Master slide ppt

  • Write the title of the presentation and the speaker's name on the first slide indicating any possible conflict of interest (please specify any consultancy relation to pharmaceutical companies, industries, etc..).
  • Save the presentation with the speaker's name embedded in the file name + the date in order to avoid that all presentations are called OB or Brussels.
  • Any video/film/image file must be in the same folder of the PowerPoint presentation and must be copied in the folder before being included in the presentation. Alternatively, use the option "Pack and go" or "Package to CD/DVD/USB" in the PowerPoint software.
  • It is recommended that embedded movies start automatically after slide transmission rather than by mouse click.
  • We suggest putting a maximum of one movie per slide.
  • Reduce the size of your presentation by choosing the option "reduce File Size..." and then "Best for viewing on screen" under the "File" dropdown menu in PowerPoint. Images with either ".png" or ".jpg" extensions are recommended in order to obtain a smaller size presentation (other kinds of cross-platform extensions - recognizable by PowerPoint, such as tiff – are also acceptable).

Procedure :  All presenters must read the following instructions

Upload your presentation prior the congress

  • A upload service prior the congress is proposed. Link to the upload server will be available closer to the congress. This is a easy way to avoid waiting time in speakers room.
Speakers Room opening hours
  • The Speakers room is open during the congress days between 7:30 - 17:30.

The OB Organising Committee ensures that all presentations are erased from computers used by the audiovisual team. In addition, no one other than the presenter will be allowed to copy PowerPoint files from the AV system.
