Instructions for poster presenters

SemDial will have three poster sessions. You can find details for your poster session on the program page.

Poster formatting guidelines are described below and we wish to call special attention to the fact that authors may present using an electronic poster.

What are electronic posters?

The ICT workshop venue has High-Definition TVs mounted on their side which can be used for poster presentations. The TVs can display image files (JPG and PNG), PDF, QuickTime movies and to a limited extent PowerPoint. The TVs do not support playing of audio or any interactivity. One of the TVs will display your file for the duration of your poster session.

Am I required to have an electronic poster?

No. Authors may choose whether to present their posters as an electronic poster (on the TVs) or as a paper poster.

Why choose an electronic poster?

An electronic poster has several advantages:

  • You save the costs associated with printing a poster
  • You save the hassle of traveling with a big poster tube
  • You can include moving images on the poster (but no audio)

The following, however, is not an option:

  • You can prepare the poster on the plane on the way to the workshop

In fact, an electronic poster may require more lead time than a paper poster, because we need to make sure that the file looks good when displayed on our TVs. We would like to receive your poster file one week before the workshop so we can test it and work with you on any necessary improvements.

The main limitation of electronic posters is the physical size and resolution of the TVs. If your poster requires a lot of fine details, then paper may be a better option. However, we have used the TVs to deliver very effective posters, so as long as you design your poster with the size and resolution requirements in mind, this should not be a limitation.

What are the allowable dimensions of paper posters?

Paper posters will be taped to the wall so the size limitations are very liberal. We recommend not going beyond 4 by 6 feet (120 by 180 cm).

What size should I use in my electronic poster?

You should format a PDF or PowerPoint file using the physical size of the TV: 74.7cm/29.4in wide and 132.8cm/52.3in tall. You should leave a small margin to make the poster look good and avoid content from being cut off.

A second option is creating an image/movie that fills up the screen (1080 pixels wide by 1920 pixels long). A third option is using a smaller size than the 1080 pixels by 1920 pixels and not filling up the entire screen.

What file formats are acceptable?

JPG or PNG images, QuickTime movies, and PDF are acceptable. The Mac minis driving the TVs must be able to display the file correctly. Giving us the file a week early will allow us to test for problems with missing fonts and other issues. We have had mixed results with PowerPoint files; authors should be aware that differences in PowerPoint versions and installed fonts may cause problems.

NOTE, multiple slides are possible with PowerPoint presentations but the slides must auto-advance and the presentation loop. We caution authors that this will probably mean that the slides will advance when you don't want them to, and/or you will be waiting for the right slide to show up.

Is there a template available?

We are providing a PowerPoint template. If you are using PowerPoint, we advise sending us both the PowerPoint file as well as a PDF generated from the PowerPoint. In any case, it is important to send your file(s) no later than September 13 to give us time for testing. If you are not using PowerPoint, you may still find the file useful as a reference on font sizes and other details.

What are some of the technical details of these TVs?

The TVs are driven by Mac minis in a machine room. The resolution being displayed is 1080 pixels wide by 1920 pixels long. Note, the physical screen is larger than your typical computer screen so small fonts and small details will not show up well.

What do I need to do next?

If you are planning to stick with paper please email the poster chair, Mark Core, to let him know.

If you want to go electronic, please email your files to Mark no later than September 13. If you are using PowerPoint, it would be great to get both PDF and the PowerPoint file.

We will post additional information as it becomes available but there’s no need to wait on starting your poster. Email Mark if you have questions.
