Document preparation: oral presentations

The allotted time for oral presentations is:
- Plenary invited oral: 40 minutes (including 5 minutes for discussion)
- Parallel session invited oral: 30 minutes (including 5 minutes for discussion)
- Contributed oral: 20 minutes (including 3 minutes for discussion)
(Other times apply to parallel and contributed orals in the Fast Ignition Workshop; please refer to the programme for more information.)
Speakers must keep strictly to time due to the large number of presentations.
Also, to avoid unnecessary delays between talks, all speakers are kindly requested to take a seat in the front row of the auditorium five minutes before the start of the session.

Presentation media: For the first time this conference, only electronic files will be accepted for oral presentations. Overhead projectors for transparencies will not be provided.

File formats: files may be prepared in Microsoft Powerpoint format or Adobe Portable Document Format (PDF). Please be aware of minor cross-platform and cross-operating system incompatibilities of these formats. Please test your presentation by trying it on a (different) Windows computer before traveling to Tarragona. Pay special attention to embedded movies, which have a tendency to fail due to incorrect file references (embedded movie files must always be in the same directory as the presentation itself).

Local copy of the presentation: Copy your presentation to the conference computer network at least one day before your oral presentation and test your presentation again. For this purpose, you will receive assistance from the conference organisation. Running presentations from personal laptops connected to the conference projector will not be allowed, as this may cause delays between presentations.
Speakers with an oral presentation on Monday are requested to come to the conference centre on Sunday afternoon to copy their presentations. Should this not be possible, they should send us their presentation.
We suggest the following methods of transferring your presentation to the conference server:

  • (Preferred) Bring your presentation on CD-ROM or USB memory stick (please test the legibility of the media on another computer than the one on which it was written).
  • (Only as last resort) Send your presentation by e-mail, two days before the conference at the latest.
Make sure you always have an alternative option (CD-ROM, USB memory stick, FTP or HTTP to your home site) in case the chosen method fails.

Style suggestions: The following style suggestions will improve the quality and impact of your presentation, helping you to get your message across.

  • The size of the auditorium is quite considerable, therefore we strongly recommend the use of large lettering for good readability at a large distance (at least font size 18, preferably font size 24 or more).
  • Try to reduce the amount of text as much as possible, only list keywords that aid the public in following the line of argument. Use enumerations.
  • Discuss only one item on each slide, do not lump several distinct issues together.
  • Highlight the main message of each slide clearly, e.g. by using bold font or a different colour for the main keywords.
  • Do not use an excessive amount of colour (so that attention is not distracted from the main message), and choose colours for maximum contrast (e.g. do not use yellow or light green letters on a white background, or brown letters on a black background).
  • Limit the use of transitional effects (whose behaviour on different computers is not always predictable) to a minimum.
  • Use large graphics with thick lines and large markers (dots). Always check that the axis labels are clearly visible, legible and intelligible.
  • Provide units of measurement for all quantitative items (including axis labels), and indicate error bars where possible.
  • Time your presentation so that you can finish within the time limit while talking at a moderate pace. Typically, prepare one slide per minute.
