Tim: OK, now we get to the ultimate in remote control.
Al: And what would that be?
Tim: It's called virtual reality. You become the remote control. You become part of the action.
Al: What kind of action?
Tim: You name it. Car racing, football... How about basketball? How would you like to go one-on-one with Grant Hill?
Al: Oh, that would be great!
Tim: Slip these on. These are virtual-reality optical sensing devices.
Al: Oh, the circuitry must be incredibly small. They look like regular sunglasses.
Tim: Now, slip your hand into this. This is a tactile sensory device.
Al: Well, this looks just like the work glove that disappeared out of my locker.
