But can it play with your cat?

Laser designated step’n’fetch wrinkle-robutler shown | The Register

The idea is that the wrinkly owner/user of future El-Es has dropped something on the floor, and finds him or herself unable to pick it up; or perhaps the thing is across the room, and going to fetch it would be a pain. Trying to tell a normal robot what you wanted would be an onerous business involving tiresome voice commands or some kind of remote TV gadget.

With El-E, one simply lights up the necessary item with a laser pointer, and the servile droid scurries to collect it. Provided, of course, that one hasn’t dropped the damn laser pointer.

I think this is actually pretty neat. It’s a nice example of a user interface that might quietly just work. Of course, it would be much neater if you could point at what you wanted with a finger. But that would require a robot capable of recognizing fingers.
