I came across this very interesting services provided by 3M when I was searching for various Eye Tracking technology. Recently, I got to try Tobii's (http://www.tobii.com/en/analysis-and-research/global/?gclid=CKnmjuelhKoCFacaQgodLmHGzA) Eye Tracking technology which was super cool! It's cost factor led me to research other inexpensive methods that captures a user's attention.
3M which is usually famous for all their typical products has now come out with a service called Visual Attention Service. They claim that they can "accurately indicate what design elements people are most likely to notice in the first 3-5 seconds". Now that is quite fascinating that they can accurately determine what catches the users attention. The way it works is that you can upload an image and instantly the 3M's VAS will generate heat maps and hot spots (based on scientific methods) that provides other information such which elements will be noticed by the user in the first 3-5 seconds.
Following is excerpts from their website:
