I don't think so. You'll notice that at the 1:30 mark he's switched from using the remote to the mouse. The pointer/cursor interface, even 20 years later, just doesn't work well when you're aiming at a screen occupying a (relatively) smallish span of your field of vision from 8-20 feet away, potentially at an angle.

My guess is that speech removes the need for typing, and everything else is via a one button remote with a whole host of gesture "smarts". Imagine flicking your wrist up to scroll and you'll have the idea.
