"Tiny Wearable Brings Smell-O-Vision to Virtual Reality"

Researchers from Beihang University and the City University of Hong Kong have developed two types of wearable odor generators that can create up to nine scents, including rosemary, mojito, pancake, pineapple, and ginger. The generators contain scented wax that can be heated in about 1.44 seconds to release the desired scent in a localized area. The researchers hope their version of this tech could be used to create a more immersive user experience in video games or 4D films as well as virtual teaching environments.
