The device is run by a smart phone application that connects to the glasses via Bluetooth. Infrared sensors in the glasses can detect when a person encounters other users equipped with Sound Perfume.
The smart phone sends the name, contact number and sound/smell selections to the other user's phone, which triggers soundtrack and scent in their glasses.
Yongsoon Choi and his team from NUS tested Sound Perfume on 52 people and found that it helped people form a positive first impression, Discovery News reported.
According to New Scientist, Choi said participants 'seemed to enjoy the new stimuli and diverse information during face-to-face interaction.'
