Why Are We Here?
• Engineers are not known for their ability to communicate ideas • Communication skills are essential for getting a research position in academics and industry
Why Are We Here?
“…You also have taught me how to create and give a bad ass presentation.
Last semester I took a Philosophy class where we gave presentations and summaries on articles we read. After one of my presentations the professor told me that it was close to the worst presentation that he had ever heard while teaching that class. (I had honestly spent almost 15-20 hours on that presentation/summary/delivery) So coming into this class I was pretty bad at all of that. Because of you, I have been able to earn a job by giving them an awesome presentation when I went onsite for an interview…” - A prior ECE 400 student
Overview
Suggestions for a Successful Oral Presentation (Public speaking skills) Building Your Technical Presentation (Presentation mechanics)
Suggestions for a Successful Oral Presentation
• • • • Define goals What is the purpose of the presentation?
Planning ahead Make the presentation count Useful presentation skills for getting your point across “Dress for the job you want, not the job you have”
Goals of a Presentation What are
you
trying to accomplish?
Update coworkers on the status of your project?
Communicate technical material?
Convey a new idea to a group of your peers?
Get people to read your paper?
Get a job?
Plan Ahead
• • • • Know your information Know your audience What do they expect?
What is their background?
If someone has presented before you: Use their work to provide context for your work Rehearse, rehearse, rehearse!
Rehearsal
THE most critical, and often ignored, part of preparing for a presentation • • Create the presentation in advance Don’t wait until the day before Don’t worry if things change Practice your presentation To yourself and to a live audience » Clarity of material » Timing
Making the Presentation Count
• • • • • Maintain control of the presentation Put yourself in the audience’s position Relate your work to others’ Allocate your time appropriately Use the high-interest times wisely Audience interest is highest at the beginning and end of your presentation
Delivery
Focus on how you present your material…is it interesting?
• • • • Attitude/Style Voice Body language Eliminate verbal filler (‘uh’, ‘um’, ‘like’)
Attitude/Style
• • • • Dress appropriately Be enthusiastic!
Relax Avoid nervous habits Give an excuse free presentation Pixelization Text too small to read Videos/link broken Eliminate technical errors BEFOREHAND!
Voice
• • • • Speak loudly enough If using a microphone, adjust voice accordingly Don’t mumble, enunciate Avoid monotony Vary pitch, tone, rhythm Repeat or pause for emphasis Don’t read slides or notes word for word Ask questions of the audience to maintain connectivity (Dr. Qi does this very well)
Body Language
• • • Maintain eye contact Don’t turn your back to the audience Look at more than one person Use appropriate hand gestures Move around?
If you are nervous, find a friend in the audience and focus on them!
Deferring Questions
“What if someone asks a question during the presentation?” • • If there is time, answer them directly and move on Deferring questions Are you going to address the issue later?
Is answering going to cause your presentation to go over time limits?
Do you have the information available?
If you defer a question, be sure to follow through
Answering Questions
• • • Don’t let the audience down Keep the intensity up This is where you can go into details Repeat the question “What if I don’t know the answer?” Address the issue directly
Don’t bluff
Answer in part, if possible Use lack of available data as networking opportunity
Presentation Skills Summary
• • • • • • • • Define your goals for this presentation Prepare your presentation in advance Rehearse your presentation Be enthusiastic Use slides as reminders, not scripts Maintain eye contact Stay on schedule Answer questions to the best of your ability
Overview
Suggestions for a Successful Oral Presentation (Public speaking skills) Building Your Technical Presentation (Presentation mechanics)
Building Your Technical Presentation
• General suggestions for constructing a technical presentation • Defining the structure of your presentation • Specifics on slide construction
General Suggestions
• • • • • • • Your presentation is a summary of what you have done
KISS
Use high-interest times to communicate important points Use repetition to enforce key points Use visual aids to support what you are saying Allocate time intelligently Reporter concept A non-technical reporter with no knowledge of your subject should come away from your presentation and be able to correctly report your key concepts
Presentation Structure
• Informative, descriptive title •

The Outline
• Multiple Options No Outline (Not recommended) Loose outline (Like this presentation) Outline page with completion markers (i.e. ‘slide 4 of 14’)
Outline callbacks - Example
Outline tracker built-in to presentation (preferred) • Purpose Prevents audience from forgetting what you’re talking about Regains attention of bored audience members Gives a rough answer to ‘how much longer is this thing?’

D. Results
• Using the equations derived from the graphs in the previous slides, predictions were made regarding the position of the victim in the frame • It should be noted that the victims that overlapped the frame and the closest victim that suffered from a shadow were not expected to be correctly identified, yet they were.

Tell ‘em
Further explanation on the significance of your work Overview of your methodology High-level, using images and diagrams where possible Gloss over the technical details here Specific problems encountered Here you can go into more detail Talk about how you solved the problems Show examples This is the portion of your presentation that grows/shrinks due to time considerations
The Conclusion
• • • • • • •
Tell ‘em what you told ‘em
Provide a synopsis Re-emphasize key points Lessons learned Discuss open problems and future work Thank your audience Open the floor for questions More technical details can be discussed here Have extra slides?
Some Comments on Presentation Structure
• • • • • Emphasize concepts, approaches, methods, and conclusions Save nitty-gritty technical details for questions or offline discussion Present material in a logical sequence Follow one central theme Limit sidetracks Use repetition to emphasize key points Provide appropriate applications for your audience Tailor your presented results to reflect audience interest
More Comments on Presentation Structure
• Reveal startling or surprising moments in your research to draw your audience into your presentation • Don’t startle yourself with unexpected content!
• During explanation of techniques, use a single data set for demonstration purposes Once the explanation is complete, show robustness through application to a variety of datasets
Slide Design Criteria
• • • Parsimony Conciseness, simplicity Say only what is important Legibility No excuse for unreadable slides!
Proper color selection Use charts, diagrams, and images in place of data tables, or large amounts of text
UNITS UNITS UNITS!
Consistency Use common format for all text, graphics, labels, etc.
More on Parsimony
• Make sure there is a good reason for every slide • Keep the number of items on a slide small • Don’t waste visual bandwidth Keep equations and text to a minimum Avoid intricate and large tables
Some Slide Do’s
• Use images and diagrams whenever possible • Avoid sequences of equations • Avoid tabulated data • Use repetition
Some Slide Do’s
• Duplicate slides when necessary • Keep a good balance of slides with text and slides with images • Spell check and proofread • Use formatting and/or color to emphasize key points • Know your audience

Spell Check vs. Proofread
Eye halve a spelling chequer It came with my pea sea It plainly marques four my revue Miss steaks eye kin knot sea. Eye strike a key and type a word And weight four it two say Weather eye am wrong oar write It shows me strait a weigh. As soon as a mist ache is maid It nose bee fore two long And eye can put the error rite Its rare lea ever wrong. Eye have run this poem threw it I am shore your pleased two no Its letter perfect awl the weigh My chequer tolled me sew.
Some Slide Don’ts
• Overload slides • Intend to use too many slides • Put information on slides that you do not intend to discuss • Show complex equations
Some Slide Don’ts
• Show code • Forget to attribute items borrowed from others (Courtesy: Brad Grinstead) • Use unnecessary animations or backgrounds – Examples
