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. Scientists say that the device will enable users to greet friends and family on the other side of the world as though they were present in the same room. Previously, scientists have only been able to use virtual reality technology to recreate sound and vision. But now the scientists have created a helmet that is named as the Virtual Cocoon.

The prototype helmet connects wirelessly to a computer which feeds information about a virtual world or another part of the real world. It features a high definition high dynamic screen – which produces pictures ten times darker, or 30 times brighter than the conventional television. A tube is connected to a box of chemicals releases smells under the wearer’s nose, while a similar device can spray flavors directly into the mouth and provide a texture of sensation. The heat and humidity can be changed using a fan and heater, while surround sound speakers recreate ambient noise. The helmet can be used to train soldiers, police officers, fire force etc. It is expected to be complete in five years and you can expect the price to be around GBP 1500 ($ 2100)
