Instructions for Oral Presenters


ACS Audiovisual Solutions will manage all speaker presentation recordings. The recording dates for the virtual IASSIDD Europe 2021 Congress are: 31st May till 15th June 2021. Please be informed that the deadline for recording your presentation is June 15th!

You will receive (via ACS Audiovisual Solutions) a personalized email inviting you to book your recording appointment. After scheduling your recording, you will receive a confirmation and further information about your virtual recording appointment.

If you did not receive this email by May 27th, or if you have questions regarding this procedure, please contact ACS: This email address is being protected from spambots. You need JavaScript enabled to view it.. Make sure that when you have your recording appointment, you have already rehearsed your presentation a couple of times. There are only 30 minutes reserved for each recording session (there are over 300 oral presentations, so there is limited time available).


  • The maximum length for your oral presentation is 10-12 minutes.
  • Any presentation slides must be prepared in PowerPoint 2010, 2013 or 2016 (MS Windows with .pptx extension). If you use a programme other than MS PowerPoint, e.g. OpenOffice or GoogleSlides, your presentation must be saved to this format.
  • Macintosh presentations (i.e. KeyNote) cannot be accommodated.
  • Set the PPT slide format in landscape orientation mode (widescreen 16:9).
  • If you use slides as part of your presentation:
    • Use a bold, sans serif font and large enough type for the poster or slides to be easily read on a typical laptop screen or tablet
    • Keep your slides simple: just a few points per slide
    • Include alt-text, audio or subtitle descriptions of all graphs, charts and images on your slides
    • Make sure that you use high-contrast colors for the best definition of your text. Please be aware that red letters or lines are usually not visible.
  • As a general rule, you should not present more than 1 slide per minute. Visual material supports your lecture and should not be the transcription of it.
  • You may include graphics and/or slide-show animation. If the presentation contains movies, they have to be coded using standard Windows codes and must be embedded in the presentation.
  • To avoid any compatibility problems, please do not use special characters (i.e. ", Ö, Ø, ñ, ®, ý, }, { etc.) and please do not use spaces in the name of your presentation or movie files. If your name includes special characters, you may want to create a graphic image of your name and place it on your first slide. Be sure to include alt-text (without the special characters: e.g. if your name is Ølaf, the alt-text would be Olaf).
  • Due to current scrutiny regarding financial transparency, IT IS STRICTLY MANDATORY that you include a disclosure slide at the start of the presentation, even if only to confirm that you have no conflicts of interest to declare. You can find the disclosure sheet by clicking here.
  • If you wish to allow attendees to contact you after the congress, make sure to include your name and email address on the last slide of your presentation.

The disclosure sheet


  • Make sure you have access to the programme “Zoom” or equivalent.
  • Your laptop or computer is connected to stable internet connection (preferably wired/Ethernet).
  • Your camera and microphone are in good working order: please test well before the call, not during.
  • You are presenting from a quiet space/office, with no background noise.
  • The space behind you is as neutral as possible, ideally with a white wall.
  • Focus the camera on your face and make sure your mouth is visible to enable lip-reading.
  • Speak as clearly as possible, and try to keep an even and adequate volume and speed. This ensures that CART and ESL interpreters can communicate your message with attendees who use these services.
  • Please speak in English.
  • Avoid jargon whenever possible: try to make your message accessible to as many people as possible, including non-experts.
  • Try to look at the camera whilst speaking.
  • Avoid low angles, i.e. keep camera at eye level – elevate your computer if necessary.
  • Avoid direct sunlight coming into the camera: front facing natural light is best.
  • You may add extra lighting above or near your laptop or computer if necessary.
  • Make sure you will not be disturbed during the recording of your presentation (please turn off your cellphone/mobile).
  • Please do a few practice rounds before the call to refine the presentation (and check your timing!)


  • To enter the virtual IASSIDD 2021 congress platform, you have to make sure you are registered to receive a personalized login.
  • Your oral presentation will be visible during all three Congress days, in the on demand section of the platform.
  • All participants have access to the on demand content during the Congress, and also afterwards until September 1, 2021
  • All interested participants can ask questions about your presentation via the CHAT in your profile on the platform, during the Congress days. They can also start a VIDEOCALL (if you are both online at the same time) or send you an email. 
  • You will receive the login details for the platform by June 30th. After you login, you can complete your profile, make plans and interact with other participants.
  • When completing your personal platform profile, you can also insert your contact details (email address, phone number etc.) and photo, so that those interested in your research can reach out to you or start following you.
