Send a scent with your message with the Scentee (ChatPerf) smartphone
This device is an attachment for smartphones which enables scent to be used in mobile communication or games."For example, suppose you want to send a message to a friend via a social network, maybe because you know your friend is tired. You can use this to send a relaxing scent along with your message. You can also use it to add scent to the notification sound whenever you get a new e-mail. We also think this device could be used with games. It could have all kinds of applications, so for example, in a shooting game, shots could be accompanied by the smell of gunpowder."
