Innovation through Microsoft.
-Kinect. This is the Playstation Eye with voice recognition and can work in the dark.
-Achievements.
-Online infrastructure with friends list, messages, voice chat.
Innovation through Nintendo.
-Wii. The Power Glove was an add on for the NES. The Wii is the Power Glove idea being sold with a console. Both use infrared to detect range and tilt. Not really innovative when you just rehash one of your old ideas.
-DS. Top screen image and bottom screen with touch controls.
-Wii U. This is just a consolized version of the DS. The TV is the top screen while the gamepad is the bottom screen. Where's the innovation? They do offer off tv play, which is like the PSP/Vita's remote play.
-3DS. The DS with glasses free 3D.
