Example Good Slides for a CHI Paper Presentation Joshua B. Gross, Penn State | [email protected] Straightforward Overview Purpose/value statement Principles of a good slide presentation Example good slides Conclusion - good slides are a good start to a good presentation Acknowledgements

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 Presenting Background Work

Dont 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 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) Visual Design

The pre-packaged Powerpoint slides are ugly. A plain background is not ugly. If you arent a graphic designer, dont try to be :-) Simple, Consistent, and Legible. Good Chart Example Frequency Follows an Inverse Log Relationship to Word Length 1 0.9 0.8 0.7 0.6 0.5 0.4 Word 0.3 Frequency

0.2 0.1 0 1 2 3 4 5 Word Length 6 7 8

9 Presenting Data Use simple charts/graphs, with (ideally) one main point per chart/ graph Dont 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

Alpha and Beta Teams Perform Better in the Evening, Delta and Gamma in the Morning 12 11 10 9 8 7 6 5 Mean Tasks Completed Per Minute 4 0600 0800 1000 1200

1400 1600 1800 2000 2200 Time of Day Alpha Team Beta Team Gamma Team Delta Team Graphs and Charts, Part 2

Dont 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 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! 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 Future Work

You may want to talk about future work Work you intend to do Work you may have already done Its 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 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 Answering Questions

An advanced tip is to have a few slides ready for questions you anticipate You wont 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.
