Before the presentation Talk guidelines Sample talk Ivan Viola

3 Presentation Preparation

4 Starting-up Target audience often differs in Duration of the talk
Interests Level of understanding Duration of the talk Available A/V equipment Collect all information you want to tell Classify information according to High-level / detail Importance Relevance to audience Build up the red thread of your story Ivan Viola

5 Structure First slide: talk title + speaker
Start with motivation and teasing results (Table of contents) Main part Description of the technique Examples Applications Conclude with taking-home information Ivan Viola

6 Difference to written publication
High-level explanation only Content reduced Attract to read the underlying written work Interactive demonstration and videos Questions and answers at the end Ivan Viola

7 Preparation Prepare well in advance! Perform test talk
Loud to yourself in front of the mirror To your friends / colleagues Make sure your test audience Understood the content Found it interesting Ask for improvements Hard training, easy job at the battlefield Eliminate stage fright by enough of training Ivan Viola

8 Support Material

9 Font size (44) Use font size ³ 24 for example 32
Turn-off auto-shape, auto-font resize If you now 32 feel like being at 24 optician’s office, this is 18 no coincidence. Also there they 14 will check, which font size you 12 still are able to read, or 10 which font size you definitively cannot read anymore. 9 Everybody fails at some point 8 we managed to see point size seven 7 or even six!!! 6 Ivan Viola

10 Nmir Nmir Font type Arial (sans serif) Helvetica (sans serif)
Times (serif) New Century Schoolbook (serif) Don’t use more than three 3 sans serif fonts Nmir Nmir Ivan Viola

12 Information amount Too much information per slide
Keep text to minimum - No sentences! 6-10 Lines / Slide 2-3 min / slide with content, 1 min / Image, Example Check typos The café wall illusion differs from the Münsterberg illusion in an important way. In the Münsterberg figure the black horizontal borders are isoluminant with the black regions. In the café wall illusion, the rows of tiles are separated by a thin line of mortar (or grout), which, for greatest effect, should be midway in luminance between the luminances of the black and white (or blue and yellow) tiles. The illusory effect obtained is that of a tilt to the mortar lines, with alternate mortar lines being tilted in opposite directions. The width of the mortar lines also affects the strength of the illusion. The strongest effect occurs when the mortar is narrow. In contrast with many other types of distortion illusions, the café wall illusion occurs very early on in the visual system, when the position of edges and brightness differences are encoded. This type of processing occurs prior to the cognitive processes of object recognition. Illusions that involve higher cognitive processes are not likely to be affected by stimulus changes that do not alter the informational content of the picture or object. Ivan Viola

13 Readability and usually there is a text next to the image with small fonts trying to explain what is on the left, maybe accompanied with arrows. This really helps to make sure that nobody will get the point :-) as here there is still some space so we can place again some small font text. Of course also with arrows through the figure Ivan Viola

14 Showing line after line
First slide: talk title + speaker Start with motivation and teasing results (Table of contents) Main part Description of the technique Examples Applications Conclude with taking-home information Ivan Viola

15 Animations Text Number 1 Text Number 2 Text Number 3 Text Number 4
and so on :-) Ivan Viola

16 Colors without meaning
First slide: talk title + speaker Start with motivation and teasing results (Table of contents) Main part Description of the technique Examples Applications Conclude with taking-home information Don’t use more than three colors on one slide! Ivan Viola

17 Bad Contrast Text in different colors on fancy rainbow background
Ivan Viola

18 Images and Videos Many images, videos, online demonstrations
Always reference the image Videos in loop (no stop) Don’t copy&paste graphics from paper Avoid scanning images Check environment if information is visible Rule of thumb (+2 levels of brightness and contrast) Ivan Viola

19 Images from Paper Ivan Viola

20 Example: Visual Quality Comparison

22 Close-ups Without antialiasing With antialiasing Ivan Viola

23 Equations Ivan Viola
