Were you ever reading a book and suddenly thought that there was one vital thing missing - a smell to accompany the words on the page?
The answer is 'probably not' but that doesn't mean someone isn't going to create a device which does it anyway. That someone is Professor David Edwards and he wants to bring out 'oBooks.' Presumably the o stands for olfactory.
The Harvard professor previously experimented an oPhone which let you send a message including a codes smell. When someone recieved the message they paired an app to their oPhone and a sophisticated series of chips created the smell for you to enjoy. And you can actually buy an oPhone right now on their site.
It's all pretty strange, but Edwards isn't done yet. The oBook tech would have you reading along to an eBook which was synced to their official app. When you reach a certain point, a smell would be released. The same principal would power their oMusic concept, letting you experience some odours as the tune continues. And there are examples already in the wild, with the firstoBook,Goldilocks & The Three Bears (the Smelly Version) on display right now intheSensorial Storytelling exhibition at the Museum of the Moving Image in Queens, NY and the firstoMusic - a scent composition bycomposer Daniel Peter Biro is showing in theMemory: Witness of the Unimaginableexhibition at Le Laboratoire Cambridge.
So if you ever wanted to send someone a smell, now you pretty much can!
