Xbox One gamepad almost had smell-o-vision and a built-in projector.

This Friday when the Xbox One releases to the public and sits alongside the PS4 on store shelves, the eighth generation of video games will be in full swing. The boxes are quite different this time around, adopting x86 architecture and massive hardware upgrades from the previous generation. What may not seem very different this time around, though, are the controllers. However, before Microsoft went with the old faithful design, the team dabbled in some experimental tech, such as built-in smell-o-vision and a projector.
