Oral presentations have a duration of 12 minutes, followed by a 3 minute question/answer period. Each room will have a Microsoft Surface computer, projector, and screen.

Format your presentation using the following settings:

  • Microsoft Office PowerPoint 2013 or later
  • Widescreen (16:9) format

Apple Users:

  • Use a common font, such as Arial, Times New Roman, Verdana, etc. (special fonts might be changed to a default font on a PowerPoint based PC).
  • Insert pictures as JPG files (and not TIF, PNG or PICT – these images will not be visible on a PowerPoint based PC).
  • Use a common movie format, such as AVI, MPG and WMV (MOV files from QuickTime will not be visible on a PowerPoint based PC).

You may use your own Macintosh laptop computer as a back-up. If so, please make sure to provide a Mini DisplayPort to HDMI. Please visit the Check In Desk to check your presentation and advise the staff of your intent to use your own laptop. Please arrive at your presentation room at least 30 minutes prior to the start of your session to plug in your laptop and check your presentation on the projection system.
