1 Electronic Visualization Laboratory, University of Illinois at Chicago Giving Presentations the EVL way Jason Leigh and Andy Johnson Electronic Visualization Laboratory University of Illinois at Chicago (last updated 12/08) Jason, you maybe a good programmer but it dont mean beans if you cant tell a good story! - Tom Moher

2 Electronic Visualization Laboratory, University of Illinois at Chicago The Introduction TELL A GOOD STORY! Rehearse an opening Know your audience. Give them a copy of your slides What is the motivating problem? Why is it important? Sound enthusiastic Everyone wants to hear a good presentation- the only one who can screw it up is you. Have you ever gone to a movie that you wanted to suck? No outline slide please- everyone knows you are going to give an intro, a middle and a conclusion.

3 Electronic Visualization Laboratory, University of Illinois at Chicago The Content Speak slowly, boldly, loudly, and clearly Choose good visible fonts, sizes and colors Dark backgrounds, light text, consistent color scheme Use slides as notes, not a book. Dont read your slides (unless you have difficulty with English because it is your second language). If you put up a formula you better explain it so that your audience understands. Pages of formulae will lose people Interact with your audience Look at your audience, all of them. Not just one person or the floor, or the screen, or your notes Define your acronyms if audience does not know them Test your slides on the projector ahead of time - Stand where the audience will be and see what they see. Can you see?

4 Electronic Visualization Laboratory, University of Illinois at Chicago How Many Slides Stay on time! Rehearse! Figure on 2 minutes per slide Really - its true If it takes less than that to go through a slide maybe it isnt worth devoting a slide to it If it takes more than 2 minutes then the slide is probably too dense You should aim to finish 1 minute before your time runs out

5 Electronic Visualization Laboratory, University of Illinois at Chicago Versions of Presentations You will often give the same talk more than once Modify your slides for this particular audience Do not have a mass of slides and skip over several of them - that shows bad planning and a disregard for your audience

6 White background, Black Text- Agh! Tolerable if you have only Overhead Transparencies. Dark backgrounds, light text. Choose good visible fonts, sizes and colors. Youre from a graphics lab, you better have pictures! Step to the back of the room and try and read this slide This is 40pt font This is 32pt font This is 24pt font - This is the limit This is 18pt font This is 14pt font This is 12pt font This is 10pt font

7 Dark Background Example Dark backgrounds, light text. Choose good visible fonts, sizes and colors. Youre from a graphics lab, you better have pictures! This is 40pt font This is 32pt font This is 24pt font - This is the limit This is 18pt font This is 14pt font This is 12pt font This is 10pt font Step to the back of the room and try and read this slide

8 Electronic Visualization Laboratory, University of Illinois at Chicago Another Dark Background Example Dark backgrounds, light text. Choose good visible fonts, sizes and colors. Youre from a graphics lab, you better have pictures! This is 40pt font This is 32pt font This is 24pt font - This is the limit This is 18pt font This is 14pt font This is 12pt font This is 10pt font

9 Electronic Visualization Laboratory, University of Illinois at Chicago Choose a good font size This is 40pt font This is 32pt font This is 24pt font - This is the limit This is 18pt font This is 14pt font This is 12pt font This is 10pt font Step to the back of the room and try and read this slide

10 Electronic Visualization Laboratory, University of Illinois at Chicago Choose colors thats easy to read This is text - good! This is text - agh!!!!!!! This is text - no!!!! This is text - good! This is text - borderline Step to the back of the room and try and read this slide

11 Electronic Visualization Laboratory, University of Illinois at Chicago Choose a good font This is 40pt font This is 32pt font This is 24pt font - This is the limit This is 18pt font This is 14pt font This is 12pt font This is 10pt font This is 40pt font This is 32pt font This is 24pt font - This is the limit This is 18pt font This is 14pt font This is 12pt font This is 10pt font Arial / Helvetica Times Roman Sans-serif fonts like Arial are easier to read than serif fonts like Times Use only one font during your talk Step to the back of the room and try and read this slide

12 Electronic Visualization Laboratory, University of Illinois at Chicago Youre from a graphics lab, you better have lots of pictures! Use pictures to wake-up the presentation But use meaningful pictures Explain the pictures to the audience Are the labels in the picture readable? Make it match your slides. You match your tie to your shirt dont you? Show a video of your application running

13 Electronic Visualization Laboratory, University of Illinois at Chicago Graphs Remember that white background & black text is bad! Invert the chart so it has a black background Dont accept what Excel gives you Fix the colors to make everything readable Everything that applies to your slides applies to your pictures and graphs Read the text for the audience if it is unavoidably too small

14 Electronic Visualization Laboratory, University of Illinois at Chicago More on Graphs Avoid 3D charts & graphs – they often make it harder to understand Avoid fully saturated primary colors Try to keep the entries in the legend in the same order as the data in the graph If you show numbers in your graph, make sure you dont have extra significant digits

15 Electronic Visualization Laboratory, University of Illinois at Chicago Tables Seconds ABCDEFGH 2 YNNNNYN 3 YNNNNYN 4 NNNYNNN 5 YYYNNNN ABCDEFGH 2 Y NNNN Y N 3 Y NNNN Y N 4 NNN Y NNN 5 YYY NNNN ABCDEFGH 2 Y----Y- 3 Y----Y Y--- 5 YYY---- Highlight important info in tables. The table on the right is very hard to read. The ones below are easier to read

16 Electronic Visualization Laboratory, University of Illinois at Chicago More on Tables Keep track of your significant digits –the results should not show greater accuracy than the original measurements. Dont let excel etc add on extra digits –in a presentation the numbers should only show enough precision for the audience to see the trend – more digits can obscure that trend – all related data in a table should have the same number of significant digits –Choose a text alignment (left, center, right) that makes it easy for the audience to see the trends in the data

17 Electronic Visualization Laboratory, University of Illinois at Chicago Animations Animation can be used to clarify diagrams, showing flows or transitions between states More often its over-used Be very careful using cutesy animation sequences in a serious presentations Do not use excessive bling like multiple types of slide transitions. Stick with one simple transition for all of the slides

18 Electronic Visualization Laboratory, University of Illinois at Chicago Movies Movies can be very nice for illustrating visualization applications and user interfaces. Make sure the movie plays smoothly on the hardware you will be using Trim the movie to show what is important rather than skipping through a larger movie

19 Electronic Visualization Laboratory, University of Illinois at Chicago The Conclusions Dont end with: well uh thats it. End with: And that concludes my talk, If there are questions Id be happy to answer them. Rehearse the close of your talk Show a fast 1 slide overview of your work Show a web site where they can get more information and your contact info - leave it on the screen so people can write it down

20 Electronic Visualization Laboratory, University of Illinois at Chicago Answering Questions Repeat the question so that everyone in the room can hear If you dont know the answer, just say so If a question will take a lot of time to answer, tell them that youd be happy to discuss this further after the talk If a member of your thesis insists you are wrong, dont spar with him/her. You will always lose. Say something like: Maybe youre right, Ill look more deeply into it…

21 Electronic Visualization Laboratory, University of Illinois at Chicago Backups Have a backup of your slides on the same machine Have a backup of your slides on a usb keychain drive or a DVD Make sure you have a backup dongle / adapter to connect your laptop to the projector

22 Electronic Visualization Laboratory, University of Illinois at Chicago Giving Demos The demo is like a play that must WORK! Rehearse your demo. Sound enthusiastic Test your demo and all its components the day before Book the equipment in advance. out a message to tell everyone not to screw up your settings & equipment Arrive 1 hour early & check all the equipment AGAIN because people will have screwed up your equipment- welcome to EVL Do you know who all the tech experts are and how to contact them? Alan, Pat, Lance? You should What is your backup plan if some component fails? What is the backup for your backup plan? What if ALL the tech fails?

23 Electronic Visualization Laboratory, University of Illinois at Chicago Giving Demos (cont) Speak slowly, boldly, clearly, competently. Give the audience a context. They are not psychic! Encourage your audience to play with the application Give them the tracked glasses. Keep the wand initially & then gradually relinquish control to audience Dont hack in a fix in the last minute, or the last day Dont develop new code right up to the moment you have to demo it. Make a firm decision of what you can show and make sure it works flawlessly Dont say anything in your slides and then later in the demo say you had a problem and you disabled it

24 Electronic Visualization Laboratory, University of Illinois at Chicago Tools for creating presentations Powerpoint / Keynote Photoshop - picture touch up XV / imageMagic / Graphic Converter - file format conversion IrfanView

25 Electronic Visualization Laboratory, University of Illinois at Chicago Just Do It- but do it GREAT! Tell a Great story ALWAYS Make the demo work flawlessly and brilliantly Speak clearly, boldly, slowly and enthusiastically Youre not doing this for course credit. This is a personal reflection of YOU and your competence Imagine everyone in EVL has died, WORK THE PROBLEM, MAKE IT WORK Do or do not, dont waste your audiences time Stay on time! Rehearse!
