A Feast for the Senses or Just a Whiff of the Future?

Smell has been the underdog of VR for years. Sure, you can ‘see’ a virtual garden or ‘hear’ a sizzling steak, but without the floral wafts or smoky aromas, something’s missing. Enter scientists like Xinge Yu and Yuhang Li, who’ve cooked up wireless wearables that bring scents to life in VR. The devices use chic and wireless miniaturised odor generators that release smells within 1.44s. 

The applications are endless - sniffing virtual flowers, testing perfumes without leaving your sofa, or even therapeutic uses for memory recall and mood enhancement e.g. the smell of sawdust will ever fondly remind me of my grandfather who worked in a sawmill. And if you’ve ever been to Thailand - yes, they’ve even perfected the durian's infamous stench!

Adding scents will significantly boost the sense of presence in VR environments. Whether it’s the aroma of a virtual buffet or the stench of rotten food in a horror game, smells will definitely make virtual experiences more real. 

For my world of learning and development, my crystal ball tells me that smell enhanced VR isn’t just for fun - it’s potentially functional for learning and the future of education. Experiments show it can improve recall and creativity in educational settings. I also wonder how this tech could revolutionise healthcare?

While smell is stealing the show, taste is also waiting in the wings. How do you feel about tasting virtual chocolate or sipping your favourite beverage digitally? I still remember the excitement I felt the first time I tried NASA space food. The paper texture tasted just like real ice-cream! 

Studies have already explored how combining visuals, smells, and gustatory cues can trick our brains into tasting things that aren’t there, perfect for calorie-free indulgence!?

Not everything smells like roses though (pun intended). Current devices are limited and syncing smells with visuals remains tricky. I mean if they get it wrong, who knows what your immersive experience turns into? I still remember my first VR experience and getting badddddd cyber sickness. Urghhhh!🤢

I’m really hoping the future is fragrant with smell and taste finally stepping into AR and VR’s sensory symphony. Can you imagine all the things you’ll be able to taste, smell, see and experience!!

The places we can go!! I’m already over-excited about the sensory revolution and it’s barely just getting started!
