Presenting at EVA London 2021

If you are presenting a paper or demonstration at EVA London 2021, please carefully read the information below. Not that presentations are online using Zoom.

Please note that your presentation or demonstration must take no longer than 20 minutes for papers or 10 minutes for demos. This includes setup and questions, so aim for 15 minutes of main presentation. Please do liaise with your session chair and check that all is working in the break before your session, not during the session itself!

Time limits are strictly adhered to. Please watch the “Chat” section of Zoom and your session chair for any signals to stop speaking during your talk. If you want to invite questions you must allow time within the 20 minutes of time allowed. You would not want to find you have only 5 minutes because others have overrun, so please be considerate of others and make absolutely sure your presentation fits in the allocated time. Session chairs will be sticking strictly to time – please help them achieve this.

If you have questions about Zoom and the available facilities, please contact us.


Demonstrations are a distinctive feature of EVA London. Instead of a conventional talk with slides you would offer an interactive demonstration of a technology or a project: a ‘show and tell’ session where delegates might be able to interact and ask questions.

Demonstrations have the same importance as more conventional papers and are allotted 10 minutes. Each demonstrator has a specific time slot for the demo portion of their paper. Please get in touch if you have any special requirements for your demo, well in advance of the conference.

Research Workshop

The Research Workshop presentations are intended to be relaxed and informal. However, it is still very important that you keep to your allotted time slot, as there is a very full programme. Slots will also be 20 minutes, with 15 minutes to speak, followed by 5 minutes Q&A and discussion. Again, please be sure you keep to time; it’s not fair on those that follow if you overrun.

General guidance

The recommended formats for slides are PowerPoint or PDF. If you wish to use video, YouTube or Vimeo may be best as online platforms. We recommend a mostly live presentation in general. It is also best not to read a script to maintain the interest of the audience. Please check that your presentation works correctly on Zoom before the conference. This is particularly important if you are using any non-standard technology or have not presented using Zoom before. Try setting up a test Zoom session with a colleague beforehand if needed. The Chair of your session will help as much as is possible online of course. Finally, good luck!
