Goals of a Presentation
Give the audience the intuition of your idea
Make the audience eager
To read your paper
To ask you questions
To discuss with you
Build relationship
Create a reputation
Get feedback

Goals of a Presentation
Show you can make great presentations
Big plus in a career
Conversely, a poor presentation can kill an application to a new position
5
Each talk is an interview talk
![Page 7: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/7.jpg)
Can You Trust Me?
Make your own opinion
Attend/watch presentations
Mimic presentations you understand/like
• Big plus if it is not your field
Never ever consider simplicity and clarity as a proof of weakness: this is talent
You can violate the rules if you have a very good reason to do so

Tell a Clear andConvincing Story
![Page 11: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/11.jpg)
Define First Your Message
The audience will remember at most one single message
Which message you want to audience to remember?
Can you express this message in less than a minute in an elevator?
Tailor you talk according to this message
Don’t sell more, but sell it well10
![Page 12: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/12.jpg)
Do Not Present Too Much
Common pitfall
“I did a lot and I will present every single bit of my work. They will be impressed!”
• That shows you are unable to deliver a message
Do not hesitate to cut your results
Better to present 10% the entire audience gets than 90% nobody gets
11
![Page 13: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/13.jpg)
Adapt to the Audience
The entire audience must understand your talk
Better to explain notions a part of the audience already knows than to lose another part during the talk
Do not overestimate the knowledge of the audience in your field
12
![Page 14: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/14.jpg)
Give a Structure to Your Talk
Give a background
Adapt to the audience
Adapt the technical granularity of your presentation
Make it fun and catchy
Motivate your work
Why is the subject important and interesting?
Focus of your work
What is this presentation/work about in a single sentence? What is the problem?
13
![Page 15: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/15.jpg)
Give a Structure to Your Talk
Show methodology and tools
Show results
Clearly show your contributions
Conclude with a summary of contributions
Impact of this work
Future work rarely makes sense unless you are really planning future work
14
Tell a story from the background to the conclusion
![Page 16: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/16.jpg)
Give a Structure to Your Talk
Give an outline
You can give it first before or after (better) the background
Repeat the outline before each new part
Use color to show where you are
Make clear the structure of your talk to the audience
No suspense
15
![Page 17: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/17.jpg)
Give a Structure to Your Talk
No need to go deep into related work (unless it is a survey)
Your contributions must be the core
But, be prepared to discuss related work
16
![Page 18: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/18.jpg)
Alternate Structures
You need to know what you are doing
More original means more risks
Alternate questions and answers
Appropriate for tutorials and general talks
Less appropriate for technical talks
• But, can be used to introduce the problem and each contribution
17
![Page 19: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/19.jpg)
Alternate Structures
No slides
Need to be a very strong speaker
Need a very well structured presentation
Need a very high effort from the audience
• You must transmit energy
Some (lazy) people don’t like such presentation
18
![Page 20: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/20.jpg)
Make Summaries
For each important result
At the end of each part of your talk
19
Clearly show the take home messages
![Page 21: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/21.jpg)
Anticipate Q&A
Q&A are part of the talk, don’t underestimate its importance
Prepare backup slides
Very impressive when it works
You can put technical details or results you did not have time to address in them
Be prepared to answer questions
Rehearse with colleagues
Be prepared to hard questions20
![Page 22: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/22.jpg)
Questions You Must Ask Before You Prepare Your Talk
My goal?
My single message?
Audience?
Background, knowledge, size, expectations
Duration?
For the talk, for the questions
Room characteristics?
Size, position of the screen, my position
21
Adapt your talk and material to each context
![Page 23: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/23.jpg)

23
Clarity and simplicity“You give the talk, slides
support it. Never compete with them, you will lose!”
![Page 25: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/25.jpg)
The Story Before the Slides
Define first your story before making any slide
The slides must not define or constrain the story
Make slides to illustrate and support your story
24
![Page 26: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/26.jpg)
Slide Template
Avoid overloaded templates
Frequent with some companies that like to justify a costly graphical identity
Unless you have a graphical talent, keep it simple
Make a clear distinction between the title and the rest
Do not use complex headers or footers
• No need to give the presentation title, affiliation, authors list, company logo, etc. on each slide

Use Slide Numbers
How do you know which slide it is over 30?
“The slide whose title is ‘Use Slide Numbers’”
“The slide after ‘Presentation Guidelines’”
“I don’t remember, go back, again, again, again, again, stop… yes this one!”
Used to ask questions and to practice
Used during audio or video conferences
At least 20 pt
Even at the back someone may ask a question

Use Slide Numbers
In some cases, it is useful to also add the total number of slides
For a defense or a short talk
• Easy way for the jury or the audience to assess whether you are close to the conclusion and will not exceed your allocated time
For longer talks don’t show the total number
A large number of remaining slides might be discouraging

The Ban Comic Sans Campaign
Some people hate the comic sans font http://bancomicsans.com
Reasons Ubiquitous
Childish, immature, naïve
Inappropriately used
Designed at Microsoft

The Ban Comic Sans Campaign
Safe side to do not use it Be aware you might upset the audience
Don’t use it for a job application
I used it in my lectures starting in 2005 I believed it looks less scary than Arial for
students
Dropped it in late 2011 (I prefer Calibri now)
It is very rare today in academic presentations

Use Large Fonts
Font must be larger than 24pt (here it is 32pt) Font must be larger than 24pt (here it is 24pt) Font must be larger than 24pt (here it is 20pt)
Font must be larger than 24pt (here it is 18pt)
Font must be larger than 24pt (here it is 16pt)
Font must be larger than 24pt (here it is 14pt)
Where do you stop to read it from the back?
Consider poor projectors, poor screens, poor eyes

Do not use a same title with an increasing number
Introduction 1/5

How Many Colors?
No more than three colors on a slide
Here I have four
Use easy to distinguish colors like dark
Blue, Red, and Green
Use colors to emphasize an important word

How Many Colors?
No more than three colors on a slide
Here I have three
Use easy to distinguish colors like dark
Blue, Red, and Black
Use colors to emphasize an important word
May be used to remind you to develop keypoints

Background Colors
Never use light colors or low contrast
They may not render well

Background Colors
I like this one
Quite relaxing to look at such slides
Looks clean and simple
Seems to work well with colors too
Red, Blue, Green (favor light colors)
Be careful with contrast
• When there is light in the room, contrast is lower
• You don’t have control on it, consider the worst case

Background Colors
Don’t use thin fonts
They may not render well
I don’t have much experience with this background
Seems to become more popular
Try it and make your own opinion

Colors and Projectors
The universal rule
Projectors never render colors as you expect
Be prepared to
Red that looks pink or orange
Blue that looks purple
Yellow that is invisible (never use yellow)
Never use colors that are too close
Dark green, red, and blue is the safe side

Be Concise
Do not write complete sentences as they make your message obfuscated in long lines of text
Never forget that nobody can read your slides and listen to you at the same time unless you are reading what is in your slides. But, you must not read your slides, this is boring
Omit technical details, there is no chance to explain everything in a single presentation. Instead, you should make the audience eager to read your work
Do not believe complexity will impress your audience, it will simply make you look unable to express your idea

Be Concise
Write small sentences
Do not compete with your slides
You give the message, the slides support it
Do not dig into details
Just deliver a message
Give a preview of your work/paper
Be simple in your explanations

Should I Show One Bullet at a Time?
Perfectly fine to show the entire slide if it is concise
No need to over animate
When appropriate, I like to show the title alone to introduce the slide
But, if you feel you compete with your slides, show one (or a few bullets) at a time
Rule of thumb: do not animate bullets (or block of bullets) on which you discuss less than 20 to 30s

Should I Show One Bullet at a Time?
But, never ever
Animate
Bullets
Too Fast
Best way to compete with your slide
In case of doubt, don’t animate

Design and Presentation Zen
Should you focus on the design of the slides?
Question of time and money
Address issues by order of priority
1. A well defined and clear message
2. A well structured (and fun) story
3. Adapt to the audience
4. Tell your story with passion (you are already top 1%)
5. Make beautiful slides
75
Slides are not the talk, they just support it

Why You Have So Much Text in Your Slides?
I am giving a lecture
There is not a single or a few messages, but a lot of technical details that you have to learn
I am using my slides as the material for my lecture
• This can be disputed, the other option is to use a companion text document
• But, I am putting in slides what I would write on a board (I have horrible hand written skills, believe me!)

Why You Have So Much Text in Your Slides?
For any other public talk from 5 to 30 minutes (that is, 99% of the talks you will have to give)
Very few text
A lot of illustrations
See annex 1 (at the end of the slide set) for one of my 20 minutes talk
For longer talks (tutorial, lectures…)
You might need text
But, focus on clarity, simplicity, and illustrations81

How to Show Something on a Slide?
You can touch the screen
Really touch the screen
• Don’t shake the hand 5 meters in front of the screen
Not always possible
• Screen might be too high or too far
Not the most professional solution

How to Show Something on a Slide?
You can use neat animations
Works in any case
Safe side
Many excellent options

Explain All Slides
Never present a slide you do not explain in details
Always drop a slide if you present it for less than 30 seconds
Spend time on complex figures or drop them
Spend time on equations or drop them
Talk on transition slides (e.g., outline reminders) or drop them
• Use transition to summarize the previous part and introduce the next one

Minimum Explanation
For each figure you must
Give for each of the x-axis, y-axis, and z-axis
• Label, unit, scale (if log scale)
Give the legend
Explain all symbols
Take an example to illustrate a specific point in the figure
• Very useful if the figure is complex

Introduce and Summarize Slides
For each important slide
Say a one sentence introduction
• What you are going to discuss now
Say a one sentence summary
• If the audience has to remember a single sentence it is this one
97
For very important results, show the take home message
![Page 99: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/99.jpg)
Be Redundant
Repeat several times
I’m going to explain…
My explanation is…
I just explained…
Never too much redundancy

Never Go Back
It is bad habit to go back to a previous slide
If you forgot something, just tell it
If you need a previously shown image, add it again
Navigating within slides will lose your audience

Never Exceed Your Allocated Time
This is a lack of respect for the audience and the next speakers
Not admissible, not professional
Should never happen if you are well prepared

Never Exceed Your Allocated Time
In case you feel you will exceed the allocated time
Drop slides
No problem to drop a full part
Never drop summary of contributions
Never stop in the middle of somewhere

One Slide Every Two Minutes
Usually everybody agrees
Now, count!
10 minutes means 5 slides
20 minutes means 10 slides
How many slides do you have for a 20 minutes talk?
• I have seen for 20 minutes people with more than 50 slides full of text!

One Slide Every Two Minutes
You can violate this rule if
You have time to explain in details all slides
You will not exceed your allocated time
You will not speak much faster
Hard to spend on average per slide
less than 1 minute (really short)
more than 3 minutes (start to be boring)

Use a Watch
On a room wall, in front of you
So that you can see it, but not the audience
On your desk
Digital one with large enough numbers
On PowerPoint
Presenter mode
• Very convenient, you can get comments and a few slides before and after the current one
104

For Long Talks
Several hours to several days
Make often summaries
• At the end of each part
• After each break
• At the beginning of each new day
Involve the audience
• “Jon, what do you remember from the last hour?”
• “Jim, can you in few words explain me this part?”
• But, don’t be too pushy: it is not an exam!
• And, always make again the summary yourself

Q&A
Reformulate questions
Make sure you understood them
Make sure everybody hear them
Be concise in your answer
Do not start a discussion
“I propose to continue this interesting discussion during the break. Another question?”
106

Q&A
Never bluff or lie
Acknowledge when you don’t have the answer
“Thank you for that point, I don’t have an answer now. We will definitely look at it.”
“I don’t know this article, but it looks similar to what we did. Can you send me the pointer?”
Never forget to send back your answer by email

Q&A
Questions might be
Aggressive
Stupid (most of the time, such questions show you made a poor presentation)
Hard to answer
Showing you are wrong
In any case never
Lie, aggress, or complain
108

Q&A
During a conference, if you don’t understand the question
Try to reformulate based on what you got
If after one try you still don’t understand it
• Ask the session chair
If after two tries nobody got it
• Don’t start a discussion at that point
• Propose to take it off-line after the talk

Use Your Body
Use eye contact
Do not stare (no more than 10 seconds)
Do not avert or switch fast
Use your hands
To support visually what you say
You can walk, but
Do not stand in front of your slides
Do not continuously walk along a line
Walk on a triangle and stop at each vertex110

Use Your Body
Stay in front of the audience
Aside the slides, but not in front of them
Do not show your back or your side
Do not persistently move while speaking
111
![Page 113: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/113.jpg)
Use Your Voice
Make a short pause before each important message
In the order of a few seconds
Pauses are even more effective than raising voice
The rhythm of the speech is what makes a big difference to catch the attention
112
![Page 114: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/114.jpg)
Use Your Voice
Vary your voice level
Speaking softly catch better the attention than speaking even louder
• Alternating loud and soft speech catch the best the attention
• You need to practice a lot to find the right balance
My rule of thumb
• Make a pause and speak softly before a very important result
Never read your slides or notes113
![Page 115: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/115.jpg)
Show Enthusiasm
If you don’t show enthusiasm presenting your own work, do you really believe that the audience will be enthusiastic
Listening to you
Reading your work
Inviting you
Discussing with you
114
![Page 116: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/116.jpg)
Use a Second Screen
Do not look at your slides on the primary screen
You must not show your back to the audience
Hard to keep the eye contact this way
Use instead a second screen (in clone or extended view)
Place it appropriately
• Stay in front of the audience when you look at the slides
Hard to see you are looking at the slides
115
![Page 117: Arnaud Legout To cite this version - CEL · 2020-06-20 · Anticipate Q&A Q&A are part of the talk, dont underestimate its importance Prepare backup slides Very impressive when it](https://reader034.vdocument.in/reader034/viewer/2022050514/5f9e63c5b03fe326231d4d54/html5/thumbnails/117.jpg)
Use a Remote Controller
Seamlessly synchronize your talk with your slides
Freedom to move
Most professional
Use a simple remote controller
Forward, backward, hide slides (black screen)
Small enough to fit well in the hand
• Never use a wireless mouse
Do not shake or point-toward-the-slides the hand when you switch slides
116

Practice
Best speakers practice the most
No improvisation or spontaneity
To look spontaneous you even need to practice more
Stand up and speak with loud voice to practice
Practice at least once using a projector
Practice with colleagues (once well trained)
The shorter the talk the more you have to practice
Be prepared to answer hard/aggressive questions117

Practice
To prepare a 20 minutes talk
Three days for a first version of the slides
Around 10 rehearsal in front of my desk
Around 5 “in situation” rehearsal
• Final version of the slides
• Stand up
• Speak loud
• May use a real projector
• Stringent time constraint
• In front of colleagues118

Practice vs. Energy
How to project energy if you lost it during rehearsals?
Don’t repeat the day of your presentation and only once the day before
Sleep well the night before
Convert your stress into energy
119

Practice vs. Energy
Practice permits to control the energy
Theatre actors performing on stage every day have to project a lot of energy
• The more they perform, the more the energy they project is appropriate
The less you practice the more you will use your energy to
• Keep the focus
• Find what to say
• Fight against your stress

Practice and Experienced Speakers
Experienced means +50 presentations or +100 hours of presentations
If it is not your case, you will never practice too much
If you are that experienced, you will probably not have time to practice that much
• Your experience will somewhat compensate a lack of practice
• But, if you have a tight schedule and want to impress, you will have to practice
121

Dress Well
Always dress better than the audience
Show that you respect the audience
If you don’t care for your presentation or of the audience, how will you dress?
• As every day!
But, do not be overdressed
Ask the dressing convention of your community/audience

Avoid Bad Surprises
Ask weeks before your talk to your session chair or organizer
Talk duration, questions duration
Presence of a projector
If you have a laptop
• Can you use it or do you have to use the computer of the conference?
If you don’t have a laptop
• Is there a computer that you can use?
• Which OS, which version of PowerPoint, PDF only?123

Avoid Bad Surprises
Ask weeks before your talk to your session chair or organizer
Audience
• If it is a well known conference, better ask your colleagues/advisor
• If it is not a regular talk at a conference (tutorial, interview, visit, etc.) you must ask
124

Avoid Bad Surprises
Make backup copies of your slides on two different supports
Don’t put everything in a same luggage
Make your slides available on-line
Make copies in several versions

How to react to…?
People you lost
You lost them, so work for the ones you haven’t lost yet
Don’t repeat what you feel the lost audience didn’t get
• You will lose the last ones that follow you
Nasty people (aggressive, commenting…)
Focus on other people
Don’t give them the opportunity to disrupt you even more
