> Another potential use is immersive online shopping in virtual grocery stores. Users could touch a specific virtual food and be able to taste that item. Are they imagining a world where everyone and their dog gets about 9000 hydrogel packs in the mail on a regular basis so you can virtually taste test everything in the store? Even in a situation where a company sends me a single taste ad in the mail I'm not putting that in my mouth. Scratch and sniff by mail is already dubious. Also the standardized taste test? What would be the difference between this and simply giving the flavor compounds in a disposable packet. What's the need for the device or the vr headset? I guess I'm getting old grumpy but when I see these "neat projects" try to turn around and say how it could be applicable in the real world my eyes roll so far in my head I nearly go blind.
