  • Patent number: 10019057
    Abstract: Methods, systems, and computer programs are presented for managing the display of images on a head mounted device (HMD). One method includes an operation for tracking the gaze of a user wearing the HMD, where the HMD is displaying a scene of a virtual world. In addition, the method includes an operation for detecting that the gaze of the user is fixed on a predetermined area for a predetermined amount of time. In response to the detecting, the method fades out a region of the display in the HMD, while maintaining the scene of the virtual world in an area of the display outside the region. Additionally, the method includes an operation for fading in a view of the real world in the region as if the HMD were transparent to the user while the user is looking through the region. The fading in of the view of the real world includes maintaining the scene of the virtual world outside the region.
