I've been thinking a lot lately about the different sensory triggers we experience at any given time during the day. It's pretty incredible if you think about it. I was riding my bike from work to the train station this evening — it was windy, rainy, and cold. A pretty miserable ride actually. However while the rain was pelting my face, my sense of smell was on over-drive from a tantalizing aroma wafting from a nearby cafe.
This made me wonder if it's possible to incorporate such a wide variety of triggers (good, bad, or both) into a design. The goal isn't to create a physical reaction, because sensory triggers don't always cause a physical reaction. In fact, we don't even notice most of them.
Such an interesting subject. I've got a feeling I may be exploring more of this in the near future.
