Your cell phone wakes you up in the morning. No big deal. You reach over to turn off the alarm, touch another button, and suddenly the smell of freshly brewed coffee wafts into your nose. But no point reaching for the cup, there isn’t one. The scent is drifting out from the phone! If you would rather wake up to the odour frying bacon and toast, that’s possible too. Welcome to the wonderful world of the “oPhone.” And we are not talking science fiction here; the oPhone already exists and will be hitting the market soon. Not only will you be able to entertain your nasal passages with a multitude of fragrances, you will also be able to send scent messages. Imagine irritating your friends back home with the scent of tropical fruit along with a picture of yourself swinging in a hammock and sipping a pina colada somewhere in the tropics. Of course your friends will have to be equipped with an oPhone.
So what makes this magic happen? A set of eight replaceable chips, each containing four “building-block scents” that can be dispensed in response to an electronic signal. The 32 basic smells can be combined to dispense a fantastic array of aromas. Select “meaty,” “cheesy” and “grilled toast,” and you’ll conjure up the odour of a cheeseburger. And of course you can experiment. Who knows what sort of a whiff you’ll get by pushing the “cocoa beans” and “meaty” buttons?
It sounds like the oPhone could be a lot of fun, but can this technology be put to some useful purpose? Maybe. You just finished dinner and there is that delectable dessert staring you in the face. You know you shouldn’t indulge, but it looks so good. Perhaps you’ll whip out your oPhone, push a button and the unpleasant smell of rotting meat will kill your appetite. There is even the possibility of diagnosing early Alzheimer’s disease. The inability to recognize certain scents has been linked with the early stage of this disease. And maybe the oPhone can even deal with the situation by helping with memory. Studies have shown that reading something while being exposed to a scent can lead to improved recall in the presence of the same scent. Trigger a smell from your phone as you put down your keys. When you want to find them again, push the button for the same scent and you’ll remember where you put them. Maybe. Of course this method won’t work to find a lost oPhone.
