Oral Presentation

Presentation Rules

First authors are expected to register and present their abstract in their assigned session.  Each registered attendee may present only once at the meeting. If the first author is unable to attend the meeting, the abstract must be withdrawn. Substitutions for talks are not allowed. See Abstract Withdrawals for more information.

Talk Specifications

Each talk is 12 minutes followed by a three minute discussion period.

Each of the two ballrooms will be staffed with a projectionist and equipped with a data/video projector and a projection screen. Presentations can be made from your Mac or PC laptop. Each video projector will be attached to a switch box so that up to seven computers can be left attached to the projector. A cable connected to the PA system will also be provided for audio playback.

Be sure to test the presentation before your session. We recommend that you arrive at the Ballroom no less than 30 minutes before the start of your session.


  • As a precaution, always bring two copies of your presentation with you to the meeting.
  • Your laptop must have a 15-pin female VGA output. Many small laptops require an adapter cable for video output. If your computer requires such an adapter, be sure to bring it and know how to use it – otherwise, connection to the projector will be impossible.
  • Set the output resolution to XGA (1024×768). This is the native resolution of the video projectors in the auditoriums. Many laptops have higher resolution, but use of higher resolutions for the presentation risks the loss of information when the image is compressed to XGA.
  • Insure that you know how to activate the external video port of the laptop. Instructions should be in your operator’s manual. Generally on PCs, a Function Key (or Shift plus a Function Key) activates the external port.
  • If you use a Macintosh laptop, be sure you know how to keep the external port active. Macintosh computers automatically detect the presence of a video projector when the computer boots and the external port is activated. Unfortunately, if the projector is disconnected while the computer is awake, the port is deactivated and a time-consuming reboot is necessary. To avoid this problem, test your presentation before your session and, before disconnecting the projector from the computer, put the computer into Sleep mode. If you do not wake the computer until the projector is reattached, the external port will stay active.
  • If your Mac requires an adapter cable for video output, please bring one with you.
