Microsoft Almost Put Smell-O-Vision In The Xbox One Controller
It was first deployed for a 1960 movie called Scent of Mystery, but it turns out that Microsoft was considering implementing a comparable technology in its Xbox One controller, reports Engadget.
Presumably you'd be smelling Call of Duty's gunpower, Madden's football player sweat, and the like. Maybe video game smells are an omission for the better.
Microsoft spent a total of $100 million researching and developing for the controller.
