Is smellovision the future of VR gaming?: 'Projectile vomiting as your headset psychically projects the scent of yeast-infected rotting fish from the pregnant fox OC on the other side of the room'

Researchers are exploring the use of ultrasound to stimulate the brain's scent-processing regions, potentially enabling VR experiences with accurate odors. This technology could also serve as a method for inputting data directly into the brain, though its practical and ethical implications remain speculative and raise concerns about potential negative sensory experiences.
