Power of eye contact

Have your say

So Samsung has launched the Galaxy S4 smartphone, and the big thing about it is that you can operate it with your eyes.

It automatically scrolls through pages as you read it, and it stops scrolling when you look away.

This made me think. What other tasks can you manage to complete just by using your eyes? I’ve come up with one – getting served at the bar.

If you widen your eyes when you look at a member of the bar staff it often seems to get their attention so they come and serve you.

I just wondered if there were any other ways you’ve managed to get something done simply by using your eyes. Not counting if you’re a hypnotist.
