I presented our Smartphone Brain Scanner at the first Quantified Self Conference in Europe. Since I believe in the eating your own dog food mantra I was wearing the neuroheadset and using the smartphone brain scanner while giving my short Ignite Talk.
If you thought giving an Ignite Talk was stressful (a 5 minute presentation accompanied by 20 slides each displayed for 15 seconds, and the slides automatically advance) then try giving a live demonstration of your research prototype meanwhile :-)
Feeling like a rock star was during the break after the presentation where I got to talk to so many interesting people from the quantified self community that were interested in our research.
