Despite working in interface design , I'm not the greatest artist in the world , so you'll have to forgive me.   You'd have something like this with an on-off switch fairly big , sort of in the corner and by itself , so you don't accidentally turn your T_V_ off while you're trying to manoeuvre other buttons. And then you have sort of one of those toggle displays for , oops , channels and volume , sort of for surfing channels and then volume , so the volume would be the up and down , 'cause volume goes up and down and then channels left to right. And then here you'd have your sort of standard , telephonish number pad.  And then on one side you would have an access to the menu on your T_V_
and on the other side a way to turn off the voice control. So that if the user doesn't want to use their voice , they can just turn it off and you don't have the remote control accidentally changing things on you.
Mm. Mm-hmm.
Um , so again you can have a little L_C_D_ light somewhere , the flip  thing and  Have I forgotten anything ? I don't think so. So , as you can see , it's a very very simple design ,
