Here you can see a wonderful usability example of a Remote Control. It's tivo HD remote control.
* For TV viewing, you need channel and volume buttons and channel selection, placed with a nice way, and especially the MUTE button is in center of Channel change and volume buttons, because that button you most of the time press in emergency, SO EASY TO FIND.
* The record button is also there between channel and volume buttons so again an emergency important button at a nice location.
* If you are watching DVD/CD, the traditional navigation controls.
* For channel selection, don't have to worry about 1 digit channel or 2 digit channel. Just press the channel numbers and then press ENTER. GREATTTTTT.
* OK and Cancel buttons (though I think , OK and Cancel should be written on Green and Red buttons) for Menu navigation but small MENU button should be there in center of the big round navigation panel.
* If add four more buttons for INPUT selection, it's a mid-level universal remote.
What a wonderful example of Usability.
