Some excellent points, some are fun too! I can see the potential in you.I've never been a great fan of the ideal of motion control in terms inducing a massive change in the way the mainstream games. Full body motion control games will always be niche in my opinion.
But I love Kinect and mostly for its passive functionality, which I hoped will be focused on and expanded.
I wished the XB1 could be programmed so that at the times when my favorite show (this season it was HBO's True Detective) is about to air and it sees me sit down alone with remote in hand it automatically tunes in.
I would like it to register that I am picking up the controller so the last game I played is readied in the background before I say a word or push a button. Making time to play that much faster.
I wouldn't mind if it noticed I have accidentally fallen asleep on the couch and makes attempts to wake me, so I won't have a sore neck in the morning.
Automatically mute sound when it hears ringing or sees I am answering the telephone.
Automatically increases the volume when it hears my mother in law call out my name. LOL.
Automatically pause video or game when it notices someone about to cross my line of sight.
There are a ton of things Kinect can do to add value to a console.
Kinect used for rehabilitation of people with multiple sclerosis and other illnesses.
