How does this color smell?
For you, the expression 2x2 = green is likelyit seems absurd, but if you had a synaesthesia - it would be in the order of things to feel the colors of numbers, smells of flowers, the sounds of smells and a lot of other mixed feelings. Synaesthesia is a rare neurological phenomenon in which the reaction of one of the sense organs or the cognitive system of a person causes an involuntary response of another organ or other cognitive system.
American Zachary Howard created a mask thatmake you a synaesthetic and will feel the smells of different colors. Howard connected a face mask, three test tubes with essential oils, an RGB sensor and an Intel Edison microcomputer to control the system. Each essential oil has an excellent smell and corresponds to a certain color - red, green or blue.
How this madness works
A color sensor located on the ring sendssignal into the microcomputer hanging on the shoulder, and the computer responds to it by signaling the tube with the corresponding essential oil sensed by the sensor. Depending on the percentage of content in the read object of each of the colors, the tubes open to different degrees; Also, depending on the saturation of colors with different power, the air blowers installed in the tubes in the mask work.
