Take a guess, what percentage of Americans over the age of 18 would scan a QR Code? Of course we can never know the answer to this question exactly because not only does it depend on the individual knowing what a QR Code actually is but also on a multiplicity of other factors such as motivation, presentation, time available etc. However if we know that in a given situation, when confronted with a QR Code, X% of the population would scan it, then that would be a nice statistic to have.
Siegel+Gale SimplicityLab have done just that and it appears as a single line in one table of a 35 page survey report (PDF). Siegel+Gale measured the perception and comprehension of the Environmental Protection Agency’s two proposed labels illustrating data about a gas/electric hybrid vehicle (QR Codes on All New Vehicles by 2012). The survey explored which of the two proposed labels (vertical or horizontal) would be most understandable to the average American and which data were of most interest.
The overall survey results are very interesting but deep in the report is the table reproduced below.
From this table we can calculate that 14.5% of all those surveyed would have scanned the QR Code. I have to admit that I am surprised at this figure, my guess was under 10% what was yours?
