Overview Slide• I will start with a statement that is too general• Mention terms I haven’t explained yet• I will talk about related work about topic you don’t know yet• Tell you more about things you have no idea• I will show you results after you have already lost me• I will conclude with conclusion
Getting Started• Don’t start with an OVERVIEW slide• Start with a question or motivating example• Give the zeroth order idea in one sentence• Show the ‘magic’ – Conclusion goes first ! – Make the audience wonder how you will get there – then on the next 2 slides show a teaser but give away the key idea!• Gauge your audience and adapt. If youre not good at gauging, just stick with your original presentation plan.
Curve of Excitement But there is more. Wait and see how next year I will Audience show you more Interest Teaser cool stuff. Go see results, people are my website. wondering how you got there ‘Whats in it for You have shown me’ You give the ‘magic’ with a audiencePeople are excited question oreven before you Cool results something they motivating can use withstart because you examplehave a great ‘Future Directions’title/abstract Nitty gritty of the math/algo/implem entation. You are losing some people but its ok. Time (or Slide #)
Curve of Boredom Audience Interest Discuss future directions Your Intended Curve Share results which you were trying to keep We don’t secret till the end People are Real Curve know the excited context of Describe second order anyway the theory details Related work Too late to share those Describe theory Audience is cool resultsNo clue what the Start with meaningless lost becausetitle/abstract, ‘Overview’ slide they don’tjargon words know ‘why’Time (or Slide #)
The S curve of excitement• The flipped S-curve of audience excitement vs. time line of your presentation. –• First 1/3: content that causes maximum excitement.• Middle 1/3: Excitement stay a constant low. But that is ok.• Last 1/3: Get everyone with you agaian. The ending should pick up(results/future directions).• In essence, the audience is really listening to you only at the beginning (and bit at the end) unless you engage them in an interactive way.
Getting StartedMotivate the context or application Why is what you are doing important? Why should people care? This could be audience background basedLogical BreaksOverview diagram of the project should be at the beginning and not at the end.Ok to have an overview slide after setting up the key concepts
READ your Slides !• Yes, read your slides .. – Do opposite of what people have been telling you• We live in a globalized world – Not all are native English speakers• Try to use same words while talking – Spoken words, pictures, and text on the slide should all be in sync (and in same order) and say the same thing. They should all also stand independently of the rest of the slides. – Important when you are publishing your ppt online with ‘Notes’
Staying on the message• Conveying key ideas with figures/diagrams/images is essential.• Repeat the key point again and again. – Roughly follow the title->question->explanation- >conclusion flow in each subsection.• Talk != paper – Give only limited information about the work. Motivate listener to go read your paper for the details. Only present what most people would understand.• You can ignore 2nd and 3rd order details – Just give a flavor of the complexity and your conclusions
The rule of 1/3rds• 1/3 of your talk should be understood by everyone (intro, motivation, results, future work)• 1/3 of your ppt should be understood by people in your field• 1/3 of your ppt should maybe understood by just a few people in the room. For this part you can include figures, equations. Just having them is enough, dont try to explain.
• Watching talk videos online – previous Siggraph presentations – VideoLectures.net – Avoid TED style for your technical presentation • Unless you want to rewind the story all the way to your childhood and how what you are doing is directly shaped by your childhood experiences• Use white board – Great if you are giving tutorial style presentation – Saves time on making nice looking slides
• During Practice Talks – Add Slide number to each slide • People can give you comment for each slide • Don’t include slide num on your final version – Ask a friend to take notes • Timing and suggestions/questions on each slide• Get a wireless remote + laser pointer• Avoid ‘rehearse’ time mode – Clicking a button during presentation is ok – Wireless remote makes it even easier
Blank slides force people to focus on thespeaker. You can hit B in Microsoft powerpoint to make the screen go blank. ‘B’ again toshow your presentation.If you are digressing from the slide, audiencemay get confused by what is on your slide.Hit ‘B’.
• Have a photo/figure/sketch on every slide• The image can be unrelated• If you run out of ideas for a photo on each slide, just search for the keyword online (here I searched ‘unrelated;)
Last Slide• Never end with a ‘Thank you’ slide ! – This is the slide that will be up for a long time during Q&A – Last slide should be • Summary of your talk • Website for further info • State problem. State conclusion. Contact info. Nice pictures – Don’t end with Acknowledgement slide • Appreciated but not useful to most of your audience • Ack slide can be one before ‘Summary’ – Don’t show a video during Q&A • You cannt squeeze out the time – How to encourage questions in Q&A • This slides should have take home points and conclusions • State some open questions at the end of the last slide.
Thank you Slide• Never end with a ‘Thank you’ slide !• Last slide should be – Summary of your talk – website for further info
‘After’ the last slide• Appendix slides – Keep them ready in same ppt after your presentation. – Explanation for possible questions in Q&A – Videos etc. – If you are posting slides online, Appendix slides can have more details
Tips from Ted Adelson• Have a good last sentence; say "thank you" and not "I will take questions". This gives the audience a chance to clap without feeling awkward. And the host a chance to take charge.• Most of the audience is interested in question, "what is in it for me?". Know your audience and try to answer their question. Also, if the audience is diverse, talk about a variety of things.• Dont assume that the audience is alert and listening to everything you say. It is okay to repeat important stuff.• Look at "bad talks" to learn how not to give one. A good talk is nothing but a not-bad talk. You do not have to do anything spectacular.
