I have been using kinect, and I know how hard it is to control it with gestures.
So, I don't believe that it will help average user a lot with controls.
Also, voice control is just a nice thing to be demonstrated. I cannot see myself speak to the TV or Phone.
Instead, Panasonic introduced a mouse-like remote control so you can browse web pages easily on a big screen, or chose content to be viewed in an easy way.
When you are "wowed" by something, don't you know that most of ordinary people(like I think I am) want to watch TV lying in a couch and possibly as many remotes around. That's TV for me.
Please don't change it!
Just give me the best picture and content you get!
