Soon you'll be able to control your computer or mobile device just by moving your eyes.
A British research team did just that with a new system that costs less than $100 - all with parts they could simply pull off a shelf.
In a moment, I'll give you all the details. But first, let's put this breakthrough in context.
You see, for most of us surfing the Web, writing emails or sending texts is so routine we don't even give it a second thought.
In fact, it sometimes seems that mobile phones, in particular, have become part of our bodies. (Just try telling my teenagers to stop texting at the dinner table.)
And yet, millions around the world simply cannot join the digital age for a simple reason.
Their bodies won't let them, either because of disease or severe injuries.
That covers a wide range of problems from adults with lost limbs or broken spinal cords to kids who have muscular dystrophy, an illness that causes the muscles to wither away.
But all that is about to change...
The Promise of Eye-Control TechFact is, cutting-edge eye-control tech promises to have a profound impact on the way humans use a wide range of machines. We're taking about everything from controlling robots and wheelchairs to setting the timer on your coffee maker.
It's thanks to the research team at Imperial College London that this tech is finally within reach.
