Your VR Doesn't Stink (Yet)

What does it smell like when the wheels heat up on that Formula 1 car you drive at night and on the weekends? You have no idea because the Virtual Reality experience that lets you do so doesn’t come with a nasal component. Yet.

 

Shown here is an olfactory device that works with Oculus Rift and other head-mounted displays. The proof of concept is hte work of [Kazuki Hashimoto], [Yosuke Maruno], and [Takamichi Nakamoto] and was shown of at last year’s IEEE VR conference. It lets the wearer smell the oranges when approaching a tree in a virtual environment. In other words, it makes your immersive experience smelly.

 

As it stands this a pretty cool little device which atomizes odor droplets while a tiny fan wafts them to the wearer’s nose. There is a paper which presumably has more detail but it’s behind a pay wall so for now check out the brief demo video below. Traditionally an issue with scent systems is the substance stuck in the lines, which this prototype overcomes with direct application from the reservoir. Yet to be solved is the availability for numerous different scents.

 

This build came to our attention via an UploadVR article that does a good job of covering some of the scent-based experiments over the years. They see some of the same hurdles we do: odors linger and there is a limited palette that can be produced. We assume the massive revenue of the gaming industry is going to drive research in this field, but we won’t be lining up to smell gunpowder and dead bodies (or rotting zombies) anytime soon.

 

The more noble effort is in VR applications like taking the elderly and immobile back for another tour of places they’ll never again be able to visit in their lives. Adding the sense of smell, which has the power to unlock so many memories, makes that use case so much more powerful. We think that’s something everyone can be hopeful about!
