The olfactory system (sense of smell) is the least engaged/targeted by the internet, and the computers in general. For obvious reasons there aren’t any applications/websites/devices (as far as I know) that interact with the user through his sense of smell, which is rather weird given the impact of olfactory memory on the psychological state. A certain smell can trigger a memory trip like no other sense, certain smells can even impact the behaviour. In this post I’m building an olfactory interaction system, whenever someone logs into Gtalk a certain smell is released into the room, replicating the real-life situation when someone steps into the room and everyone recognizes him from the perfume he always wears.
To do this I’m going to use:
- Arduino Uno
- A bank of Air wick’s fresh matics (at least 3 each with a different perfume)
- Netbeans and some Java code
