Samsung Electronics, which has already begun to mount a media campaign to hype its upcoming Galaxy S IV flagship phone, will reportedly include an eye-scrolling application on the device. The feature will allow text to scroll by tracking a user's eyes -- the software would automatically turn to the next paragraph when a reader's eyes hit the bottom of a page, for instance. Samsung is expected to emphasize new software -- rather than hardware -- on the Galaxy phone when the South Korean company introduces the handset on March 14.
