The newest add-on for your smart phone, Japan’s Scentee, moves beyond the visual and taps into users’ olfactory sense. Plugging into a phone’s earphone jack, the orb-shaped device can be programmed to disperse different scents throughout the day. Replaceable cartridges allow the user to choose from a multitude of scents to suit their mood or environment: coffee as you wake, lavender in a crowded subway, or mint as a mid-day refresher. The latest scent in the pipeline? Bacon. In other fragrance news, the Ophone, a small cylindrical gadget designed by Le Laboratoire receives encoded recipes through a server that determines what custom scent it emanates. The current prototype generates up to 320 different smells.
