Virtual Reality Headset

From DailyMail.co.uk (March 5):

A virtual reality helmet that recreates the sights, smells, sounds and even tastes of far-flung destinations has been devised by British scientists.

The device will allow users a life-like experience of places such as Kenya's Masai Mara while sitting on their sofa.

They can also enjoy the smell of flowers in an Alpine meadow or feel the heat of the Caribbean sun on their face. [more]

Cool! This is the first time, according to the article, the manufacturer was able to simulate smells in a VR device. I just hope the manufacturer doesn't simulate toxic smells like smoke. Firemen who using the helmet don't need to smell smoke. They might need to know if it is in a building but not need to smell it. Also you don't want the other inputs of the helmet to harm the user either. This is just common sense.

It would be a good idea if the user was allowed to control the input of the helmet. That is to allow the user to turn off the sense of smell or hearing or whatever.

If it comes to a point that VR is indistinguishable between real life and virtual life there should be a "VR" symbol in the simulation so the user can know what is real and what is not.
