Oral Presentation

Presentation Rules

First authors are required to register and present their talk in their assigned session. If the first author is unable to attend the meeting, the abstract must be withdrawn. See Abstract Withdrawals for more information.

Talk Specifications

Each talk is twelve minutes followed by a three-minute discussion period. A timer is provided to help you keep time. There is no transition time allotted between talks, so it’s important that your talk start and end on time.

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. At the time of your presentation, press the numbered button on the switch box that corresponds to your presentation to project your presentation onto the screen.

Please arrive at the talk room no less than 30 minutes before the start of your session to check in, receive final instructions, and test your presentation on the projector.

An audio cable is provided to connect to the PA system in the room. If you are playing audio, inform the technician in the room so the audio level can be adjusted beforehand.

If you will be playing video during your presentation, we recommend testing the video clips on the projector to ensure that they play correctly.

Reminders and Recommendations

As a precaution, always bring two copies of your presentation with you to the meeting. Bring a copy of your presentation with you to the talk room on a USB flash drive. Should you encounter a problem using your own computer, this facilitates presenting on another computer.

If you have embedded content in your presentation (such as video clips), make sure you bring all externally referenced files with you to the meeting.

The projector screens are 4:3 aspect ratio, so using 4:3 slides is recommended. Widescreen slides (16:9) can also be used, but there will be black bars at the top and bottom of the screen.

Your laptop must have a 15-pin female VGA output. Many small PC laptops, and all Macintosh laptops, require an adapter cable for video output. If your computer requires a VGA adapter, be sure to bring it and know how to use it – otherwise, connection to the projector will be impossible. VSS does not own or supply VGA adapters.

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 before the projector is reattached, the external port will stay active.

It is recommended, but not required, that you set your output resolution to XGA (1024×768). This is the native resolution of the video projectors in the auditoriums. Use of higher resolution for your presentation risks the loss of information when the image is compressed to XGA.
