Incorporating scents into a virtual reality environment suitable for astronauts

Stop and smell the roses - from outer space

Astronauts are heading to the moon, and this time they’re targeted on establishing the primary long-term existence. Subsequent, NASA set its sights on a visit to Mars.

With these long-term duties forward, new challenges should be thought-about on all fronts. The Moon is about 238,855 miles from Earth, however an astronaut’s journey to Mars means touring about 140 million miles and leaving our planet for about three years. Due to this distance, astronauts may also expertise a delay of as much as 20 minutes in communication from Earth to Mars.

Whereas these missions and the potential for discovery are thrilling, astronauts will want extra assist in managing the behavioral results of isolation, confinement, and distance from house.

“For future, long-term missions, we cannot have real-time communication or the power to ship care packages like we do now, so NASA is in search of different methods to assist protect Behavioral well being mentioned Renee Abbott, a doctoral scholar within the Division of Aeronautical Engineering at Texas A&M College.

Abbott is working with college advisor, Dr. Ana Diaz Artiles, assistant professor within the division, to handle this concern utilizing Digital Actuality (VR). Particularly, they’re learning the consequences of incorporating odors right into a digital actuality atmosphere.

“Throughout long-duration spaceflight, astronauts expertise important sensory deprivation. This may have dangerous penalties on a number of ranges, from physiological responses to emphasize and isolation to deterioration in behavioral well being and wellness,” mentioned Diaz Artiles. “We’re creating ‘enhancing’ or ‘enriching’ multisensory experiences that may result in more healthy people with improved behavioral well being and functioning.”

Once we ingest a scent, info from these scents travels from our olfactory system to our limbic system, which is part of the mind related to emotional processes and reminiscence. That is why a scented candle can remind you of do-it-yourself cookies at Grandma’s home, or a perfume can evoke some emotion.

Abbott and Diaz Artiles give attention to the consequences that scents can have on individuals Psychological state By introducing scents right into a pure atmosphere for digital actuality. Smells have been added to a VR expertise earlier than, however Abbott and Diaz Artiles’ use of native scents separates their work from earlier analysis.

The consumer can stroll close to the river in a digital actuality atmosphere and never solely hear the sound of flowing water but in addition scent the moist grass. Or in the event that they wander right into a wooded space, they scent the recent scent of pine. That is completed utilizing Hitboxes, that are invisible shapes within the VR atmosphere that activate when an avatar collides with them.

“We hope that utilizing digital actuality to speak nature to astronauts will probably be useful,” Abbott mentioned. “On Earth, nature has useful results for us each psychologically and physiologically, so we try to create as shut a simulation of real-world nature as we will by including olfactory stimuli.”

When conducting their research, Abbott and Diaz Artiles measured the customers’ anxiousness ranges earlier than and after publicity to a stress-inducing occasion. The outcomes confirmed that the addition of olfactory cues not solely lowered the customers’ anxiousness ranges after experiencing elevated stress but in addition lowered their stress and anxiousness ranges from baseline.

Their research was described within the August challenge of the journal house acta.

“The outcomes recommend that the usage of multisensory digital actuality environments is a promising countermeasure to assist behavioral well being,” mentioned Abbott. “We may also take a look at including different sensory stimuli, resembling illusions of temperature, and the way we will use this know-how to create digital care packages.”

Digital care packages can be utilized to complement astronautssocial wants by serving to them really feel extra related to house. Abbott envisions, for instance, {that a} beloved one can ship a recorded message and digital flowers accompanied by the scent of lavender and rose.

The researchers additionally hope to collaborate with the Navy to run experiments on the ships over a couple of weeks to look at extra long-term results in an atmosphere much like the sensory deprivation skilled by astronauts.
