Scientists are developing a virtual reality technology that allows not only to see but to smell augmented 3D environments.
Engineers from Beihang University in China and Citi University in Hong Kong have created a futuristic headset that can emit 30 different scents to the wearer, including coffee, waffles and ethanol.
The project, stranger than fiction, aims to launch a unique experience for virtual reality users, by expanding the range of “physical experiences” that they can live while playing.
She added: “Smell plays an important role in human perceptual experiences, and it is just as important as vision and hearing.”
The team’s pioneering technique uses small paraffin wax-filled pads, infused with scent, that are heated by an attached electrode, to release the scent.
Wireless scent generators, referred to as OGs, can be placed directly under a user’s nose.
Another design proposed by the team is for the user to wear a face mask.
The study suggests that odor generators could be used outside of augmented virtual reality games, including to enhance the experience of distance learning classrooms.
The engineers also suggested using the device to help amnesia patients recover lost memories.
