Scientists at Sweden's Stockholm and Malmö universities have created a three-dimensionally (3D)-printable "olfactometer" that can generate odors in virtual reality via a gaming controller. The researchers deployed the scent machine in a game where players guess types of wines in a virtual cellar by their aromas. When the players lift virtual glasses, the olfactometer attached to the controller discharges an odor. The olfactometer has four valves that are each connected to a channel, which under the player's control open to a different extent and release unique fragrance mixtures.
