There are certainly more sophisticated ways of doing UI heat mapping and click tracking, but this lo-fi version is easier to relate to, and what’s more, you can do it at home! All George Kokkinidis at Design Language News did was clean the iPad’s screen carefully, use an app for a little while, and then photograph the screen in such a way that the fingerprints caught the light. Voila, instant heat map.
It’d be interesting to try this backwards: look at a fingerprint pattern and try to reconstruct the usage scenario from there.
