Samsung launches Galaxy S4 eye-tracking smartphone

  • Samsung have launched a smartphone that enables users to control its 5-inch screen using just their eyes.

    The Galaxy S4 follows on from last year's S3, of which 40 million units were sold worldwide.

    Using "Smart pause", users can pause a video by looking away from the screen.

    The "Smart Scroll" software also analyzes the user's eyes and wrist movements to scroll through emails and other content.

    At a Broadway-themed event in New York on Thursday night, the company also showcased the phone's ability to take two different pictures at once using its dual camera.

    The rear-camera has a 13-megapixel camera while the user-facing camera captures pictures at 2 megapixels.

    The Galaxy S4 will hit shelves across the world at the end of April.

    The device weighs 130 grams and is 7.9mm thick, making it slightly lighter and thinner than the S3. It will available in white and black.

    Along with the "touchless" technology, the South Korean firm also introduced the Samsung Hub, a multimedia storage facility that can be shared across various Samsung devices.
