Researchers have created a new device that uses ultrasound to trigger smells directly in the brain for VR The small device rests on the forehead with a soft gel pad. It sends gentle sound waves through the skull to the area of the brain that processes smell. Current VR smell systems use cartridges that need constant refills and can make a mess. This new method is cleaner and could one day let people smell virtual worlds like forests or oceans naturally. The project is still in early prototype stage from a small research team. Safety levels were kept low, but more testing is needed.
