In Samsung Galaxy S4, the Samsung company has implemented technologies that follow the user's gaze to scroll a page, or to stop a video clip that is playing on the terminal. Apple Lossless Audio CODEC (ALAC), try to register as an invention a similar technology, which allows iDevices to stop playing a multimedia content when the user is not looking at the screen, this being the equivalent of the function Smart Pause from Samsung Galaxy S4.
For example, the electronic device may be performing a video playback operation while in the active mode. In this example, when the electronic device detects that the user's gaze is no longer directed towards the electronic device, the electronic device may enter one of the standby modes, dim the display screen that was being used for the video playback operation, and pause the video playback operation. If desired, the electronic device may resume the video playback operation when it detects that the user has redirected their gaze towards the electronic device (eg, towards the video screen).
Apple uses the front camera to detect the user's gaze, and in addition to stopping/starting the playback of multimedia content, the system can automatically close the screen when we are not looking at it, but the Internet is also used for this function. The technology that Apple is trying to register would be joined to a similar patent registered to Apple in 2010, describing methods of tracking the gaze of users of a mobile terminal.
Apple and Samsung have registered similar technologies in this field, but the Koreans have a basic patent registered in 2000, so in case of a possible lawsuit, Apple could lose.
