A group of UK scientists from the Universities of York and Warwick are attempting to bring us one step closer to a true Star Trek holodeck experience with the invention of the Virtual Cocoon. The helmet features a high-definition screen, surround sound, tubes connected to a mixture of chemicals that emit certain scents depending upon the program, as well as a tube designed to spray flavor chemicals into the wearer's mouth depending upon the visual experience.
Temperature is also controlled, mimicking heat and humidity, using a small fan and heating unit situated at the back of the helmet. The creators expect the device to sell for around 1,500 pounds ($2,675) when it's ready for public consumption in about five years.
