One of the most unexpected AI applications I've seen
AttentionWizard is definitely one of the most unexpected AI applications/start-ups I've seen. They simulate of humans visually process web sites in order to optimize their layout. Usually done with eye and mouse tracking of live subjects they use a simulated persons instead. I'm doubtful how accurate it can be (they claim 75%+ correlation to the real deal), but if it's actually working it can be incredibly useful.
AttentionWizard uses advanced artificial intelligence algorithms to simulate human visual processing and attention. Our software instantly creates an “attention heatmap” of your Web page that predicts where real people would look during the first few seconds of their visit.
And this is what it looks like for a Google Result Page:
