VR System to Turn Smells into Temperatures

Here is quite an interesting play,  hacking your nose to get a temperature experience?  Skiing VR  experiences?  Thinking about the reality of this.    Temperature sensations .... how about others?

VR System Hacks Your Nose to Turn Smells Into Temperatures

University of Chicago (UChicago) researchers have developed a power-efficient technique for generating different temperature sensations in virtual reality (VR) by essentially hacking the user's nose. The system disperses atomized chemicals to access the trigeminal nerve in the nose in order to replicate hot and cold sensations through odors. The device can produce discrete levels of hot and cold, and vary their intensity by tuning the frequency of the chemical dispersal. UChicago's Jas Brooks said, "Ultimately, any kind of new modalities for VR/AR (augmented reality) will only succeed if they are feasible in a mobile/untethered context. If we want to have thermal experiences that are portable, the device needs to be power-efficient."
