Good article on 3M's work in visual impact scanning. We had talked to them years ago about their research to understand its possible use in store and marketing interactions. Note the potential competition between this and similar goal methods used in neuromarketing such as EEG brain scans. Brain based methods can in theory be seen to probe deeper and go beyond just attention, but 3M has done much more research to drive this to a quantitative level. Store display and interactive displays in particular should benefit from these methods. They offer a free trial of the method.
