Speaker Instructions

Author notification letters will be sent by e-mail to the individual who submitted the abstract. For a quick way to find out the method of presentation and time assigned to a specific abstract, use the author index provided.

Important Note about Social Media: LPSC microbloggers will be tweeting during the oral sessions. If an individual speaker does not want his/her talk to be tweeted or otherwise reported on, it is the responsibility of the speaker to make that request at the beginning of the talk. We will not close an entire session to microbloggers.

Speaker Guidelines —

Oral presentations are scheduled for 15 minutes per talk: 11 minutes for speaking and 4 minutes for discussion and speaker transition. A two-minute warning will be issued at the 9-minute mark.

Audio-visual equipment provided will include laptop PCs and Macs and an LCD projector. There is no option for dual-screen presentations.

Speaker-Ready Room —

Presentation validation will be in the speaker-ready room (Alden Bridge). Checking in oral presentations is the most important step presenters can take to ensure their presentations are successful. Those presenting on Monday morning should check in their presentations on Sunday between 4:00 p.m. and 8:00 p.m.

The speaker-ready room will be open during the following hours:
Sunday, 4:00 p.m. to 8:00 p.m.
Monday through Thursday, 7:00 a.m. to 5:30 p.m.
Friday, 7:00 a.m. to noon.

Two options for electronic presentations are being offered at the 50th LPSC. Please read the following detailed instructions for each option. The deadlines for submitting electronic presentations, regardless of the option chosen are:

** Presenters for Monday morning sessions must turn in their presentations on Sunday night, March 17, between the hours of 4:00 p.m. and 8:00 p.m.

Presenters will be required to verify their presentations on LPI-provided equipment at the time presentations are turned in. After readability is confirmed, presentations will be loaded in speaker order on session laptops. Revisions to presentations will not be accepted after the submission deadlines mentioned above.

Note: Conference-room LCD projectors will be configured for 16:9 aspect ratio display. Presenters must have their slides formatted for 16:9 aspect ratio for best compatibility.

Electronic presentations in PowerPoint, PDF, or Keynote format (see Software Specifications below) must be turned in on a USB flash drive to the speaker-ready room no later than the times listed above.
Note: Participants who are unable to meet the deadlines listed above must contact the USRA/LPI Computer Center for assistance (e-mail: lpsc-it-help@lpi.usra.edu) no later than Thursday, March 14 for instructions.

TECHNICAL SUGGESTIONS FOR ELECTRONIC PRESENTATIONS —

These suggestions are not meant to deter creativity or use of the best data available, but to provide suggestions for optimum results.

Readability — Keep in mind that those sitting at the back of the room will have difficulty reading information that is not well presented. For the benefit of your entire audience, please keep the following tips in mind:

  • Graphics should be simple, well-designed, and legible to everyone in the audience.
  • Presentations are most readable on a dark background with bright lettering. To make certain your slides are legible, view your slides at a distance of 8-10 feet from your computer screen.
  • Avoid using small fonts, which will be illegible from the back of the room. Break up a complex slide into a series of slides. Avoid including critical information at the bottom of the slide, which is not always easily seen from the back of the room.
  • Devote each graphic to a single fact or idea. Illustrate major points, not detailed data.
  • Avoid long or complicated formulas or equations.
  • Use the minimum number of words possible in titles, subtitles, and captions.
  • Use bold characters instead of fancy type.
  • When preparing graphs, avoid more than two curves on one diagram whenever possible. If three or four curves must be used, make certain they are well separated. Label each curve; avoid symbols and legends. Avoid data points unless scatter is important.
  • Colored graphs are very effective as color adds interest, attractiveness, and clarity to illustrations. Contrasting color schemes are easier to see.
  • An introductory and a concluding graphic can improve the focus of your talk.
  • It is strongly encouraged that presentation files (PowerPoint, PDF, etc.) be much smaller than 150 MB.


PowerPoint — can display pictures and text generated with the program or inserted from other sources. If the outside source is a video file, the original file is not saved within the presentation. Source files meeting these criteria must be available on the computer on which the presentation is going to run. Presenters should copy any source video and sound files to the USB flash drive containing their presentation. When in doubt, include the file. Macintosh LZW compressed TIFF files may not display correctly with PowerPoint on a PC.

Fonts — should be standard fonts such as Times New Roman, Arial, or Courier. If nonstandard fonts must be used, they should be embedded in the PowerPoint file. We recommend a minimum font size of 24 points.

Embedded charts, graphs, and object-oriented graphic files — can be difficult to work with. These file types usually are influenced by the version of the program used to create them, often making them translate strangely on a different system. We recommend that charts or graphics be inserted into presentations in a standard graphics format such as .gif, .jpg, or .bmp.

Movies — saved as MP4s have the best chance of success in PowerPoint. QuickTime’s best compression algorithm, the Sorenson CODEC, does not play within PowerPoint. To avoid problems, convert video files to MP4 format encoded with H.264 (aka, MPEG-4 AVC).

Internet Hyperlinks — will not work on the presentation computers. These computers will be isolated from the Internet for security purposes.
