Called the "smelling screen," this technology created by a team led by Haruka Matsukara from the Tokyo University of Agriculture and Technology in Japan can produce odors that appear to emanate from specific areas of the screen, Gizmag reported.
The smelling screen uses four fans positioned at its corners to create a virtual odor source that appears to come from a specific area of the display. Instead of simply blowing the odors toward the viewer (or smeller), according to Gizmag, the airflows generated by the fans collide together before being directed out at the viewer, so the smell appears to be coming from the screen rather than the fans.
