3. Statement of Purpose/Value
•
A good presentation starts with a
statement of the value of the work
• Why should people care?
• Why should they hear your talk?
• What contribution have you made?
•
This information is probably in your
abstract, but should be distilled for the
slide
4. Presenting Background Work
•
Don’t try to present all the background
• Just one or two really crucial elements
• The CHI audience is broad, so briefly
describe
• Examples follow
•
Participatory Design
• The theory and practice of involving
users at some or all stages of design
•
Semiotics
• A theory of how systems of symbols (like
a language) communicate ideas
5. Citing Prior Work
•
It may be beneficial to cite prior work
• It should be important and relevant
•
Use this style (Simon, H. A., 1975)
•
Often, this is used to give your audience a perspective
• “Participatory design (Nardi, B. A., 1993)”
is not the same as
• “Participatory design (Bodker, S., 2000)”
6. Visual Design
•
The pre-packaged Powerpoint slides are ugly.
A plain background is not ugly.
If you aren’t a graphic designer, don’t try to be :-)
•
Simple, Consistent, and Legible.

8. Presenting Data
•
Use simple charts/graphs, with (ideally)
one main point per chart/graph
• Don’t try to jam too much data in
your graph
•
Labels x and y axis, and units
•
Use a title that clearly explains the idea
you are trying to get across

10. Graphs and Charts, Part 2
•
Don’t just accept defaults from Excel
• Colors (including background) may
need to be changed
• Axis dimensions and scale can be
changed
•
Make sure text is big enough
•
Move legend to where it is most useful
•
Make sure colors & background are visible
on a projection display
11. Acronyms
•
Acronyms are dangerous
• Example: ERP
• Does it mean Enterprise Resources
Planner
• Large-scale corporate planning
software
• Or does it mean Event-Related Potential
• Reactions measure via
electroencephalograph
•
Always spell out acronyms at first use
• E.g. Event-Related Potential (ERP)
• One safe exception - HCI!
12. Slang and Colloquialisms
•
Avoid slang and colloquialisms if at all
possible
• CHI is an English-language
conference
• 2 billion people speak English
• Lots of dialect and regionality
•
Make your message clear to people who
speak English as a second language
• Or third, or fourth…
13. Future Work
•
You may want to talk about future work
• Work you intend to do
• Work you may have already done
•
It’s been up to six months since you
submitted your paper
• What direction is the work taking
• What do you see as the major next hurdle
or accomplishment
14. Summary and Acknowledgements
•
Summarize your major contributions
• Good slides are the basis of a good
talk
• Assume a broad audience at CHI
• Make sure your content is readable
• Stop on your summary slide - this
is useful for your audience
•
Acknowledgements
• Funding
• People
•
Include your contact information
15. Answering Questions
•
An advanced tip is to have a few slides ready
for questions you anticipate
• You won’t always have one for each
question asked, and you may not use
them, but they can be handy
•
This is a useful place to put
additional/supporting data, references, etc.
