A team of University of Utah Electrical and Computer engineering Professor Carlos Mastrangelo and doctoral student Nazmul Hasan has created the “Smart Glasses”. These glasses have unveiled at Consumer Electronics Show CES last month – are made of liquid lenses that automatically focus on whatever the wearer in looking at, whether it is far away or up close.
“Most people who get reading glasses have to put them on and take them off all the time,” said Mastrangelo. “You don’t have to do that anymore, you put these on and it is always clear.”
How Smart Glasses Work?
A distance sensor in the bridge of the glasses uses infrared light to calculate the distance between the glasses and an object. The sensor then tell “actuators” to reshape how the liquid lenses are curved. The curvature of a lens can control the focal length. That’s happens naturally in the eyes as well.
Normally, when you are at young stage, the lenses of your eyes are flexible so they their curvature easily that allows you to focus on objects far away and up close. And when you get old, your eyes lens become more rigid and that’s the cause of why it becomes hard to read the book.
The Smart Glasses lenses are curved, which allows you to focus on whatever you looking at. It takes about 14 milliseconds for the glasses to change focus. These glasses have an eye tracking and a depth camera, so the lenses can more accurately figure out what you are looking at.
All those added features will consume energy, so that why the team create a more powerful battery, which also small enough to fit in a stylish pair of glasses and the rechargeable battery in the frames lasts more than 24 hours.
Mastrangelo said at Consumer Electronics Show CES, “The response was phenomenal.” The current design is bulky, but the Mastrangelo and doctoral student Nazmul Hasan are already working on it, that how it will become much lighter, slimmer and stylish and more capable version of this set.
Mastrangelo said that the Smart Glasses will become available in two or three and will cost around $500 to $1,000.
“Our smart autofocus eyeglasses can compensate for the focusing loss of the eye so most aging individuals afflicted with far or near sightedness wearing these sets can see sharp images all the time,” he says. “They are worth the price.”
