Olfactory Assist Mask



We have developed an olfactor assist mask that presents the amplified olfactory stimuli to the subjects. The system consists of a gas sensor and an odor generator. The sensor measures the concentration variations of a gaseous chemical compound wafting in the air. The odor generator presents the user with an odor with amplified concentration variations. Thus, the user of the olfactory assist system can virtually have an enhanced sense of smell. These systems can be viewed as olfactory versions of augmented reality systems. The user's perception of the world is altered by modifying the olfactory stimuli perceived by the user's nose.
