Samsung is releasing a new smartphone that people can control with their eyes and by waving at the device.
The Galaxy S4 phone has software that analyzes peoples' eyes so users can put a video on pause just by looking away from the screen.
People can also use their eyes and wrists to browse through emails and other information.
"We have a new king of the smartphones," USA Today quoted lead analyst Roger Entner of Recon Analytics. "The Galaxy S4 is topping every other phone with its impressive hardware and new customized software features."
Samsung reportedly expects to sell up to 10 million of the new phones a month.
