How to prepare your presentation

Length of presentation

1) PARALLEL ORAL PRESENTATION     12 minutes + 3 for discussion
2) KEYNOTE LECTURE                             40 minutes + 5 for discussion

There will be a timer for keeping your time. This equipment will be well seen at the preview display and the time will be also controlled by the chair of the session.

We strongly ask all the speakers to keep the time of their presentations.


Please use the Microsoft PowerPoint 97–2007, 2010 or higher versions* (*.ppt) or (*pptx), or Adobe Acrobat Reader (.pdf) to guarantee they will open successfully on an on-site PC.

We recommend you to save your PowerPoint presentation using PPT(X) format instead of PPS.

At the WOS 2017 Conference all the screens will have the format ratio 16:9. We suggest all authors to prepare their presentation in the same format – 16:9. Please take this as a strong suggestion. The presentations in the 4:3 ratio can be also used, however the ratio 16:9 will better fit to the screens.

Please note that if you use MacIntosh-based (APPLE software) presentations or your own laptop, please check in advance (preferably 2 hours before your session starts) their Windows compatibility.

Recommended font sizes 40, basic text app. 30, min. 20. Presentations should be clear, legible, so that texts, pictures, graphs, tables and equations were clearly visible from a distance.


JPG images are the preferred file format for inserted images. GIF, TIF or BMP formats will be accepted as well.

Images inserted into PowerPoint are embedded into the presentations. Images that are created at a dpi setting higher than 200 dpi are not necessary and will only increase the file size of your presentation. Try to avoid overloading your presentation with unnecessary images.

In case you have any videos in your presentation – please test your presentation with the on-site PC several hours before your presentation. Generally, the MPEG-1 and AVI format should work with no difficulties.

How to save your presentation

Please save your presentation on one of the following disc or medium:
• USB flash disc

Save all files associated with your presentation (PowerPoint file, movie/video files, etc.) to one folder/location.

In case you are presenting more than one presentation during the WOS 2017 Conference, save different presentations to different folders and name them clearly to avoid on-site misunderstandings and problems.

Always make a backup copy of your presentation and save it on a different portable disc or medium than the original presentation.

DVD-RAM – will not be available.

How to submit your presentation at the Conference

Please come to the Meeting Room where you have your presentation at least 1 ½ hour before the beginning of your session (during the break). In case your speech has been scheduled for morning session please come one day before the day of your presentation.

Other information

• During your lecture you will be using Remote Control for controlling your presentation.
