The scent of smell is tough to work into any media – attempts at getting it into movies date back to the 1930s, and Disneyland and Walt Disney World include scents in some of their attractions. It was only a matter of time before someone tried to add it to a smartphone.
A Japanese firm among others is working on a device about the size of a USB device which can be attached to any smartphone. The device is actually a small tank which contains a specific scent. After the device is installed a screen comes up with “puff” button which when pushed releases the scent.
The whole idea of the unit is besides a picture or a sound clip one can send a scent. Travel agencies could use the device to add smells to their add, One could smell the ocean breeze at a Malibu retreat or maybe the local restaurant could send the smell of their steak and fries dinner or a perfume company could send the scent of a new perfume smell, all while holding their smartphone.
The question is where the technology will even catch because in the past Smell-O-Vision devices were not received well by movies. There is one drawback to the device, one has to get their nose close to the device to actually get a whiff and people may not take to sniffing their phones in public.
