Eyewear to Stimulate Olfactory & Audio Experiences

Source: New Scientist, Dec 2011

A team at Keio University in Tokyo have built a system that allows people to identify themselves with unique smells and sounds.

Sound Perfume consists of a pair of glasses fitted with speakers and odour emitters located behind the ears, along with an app running on a smartphone that connects to the glasses via Bluetooth. The idea is that you use the app to choose a personal sound and smell for others to experience when you meet them.

Infrared sensors in the glasses detect when you meet someone else using Sound Perfume and your cellphone sends your name, contact number and sound/smell preferences to their handset, which then triggers the appropriate response in their glasses. The current set-up makes use of eight different perfumes in the form of hard blocks that melt and release an aroma when gently heated by a wire to 46°C.
