  • Method to detect misalignment and distortion in near-eye displays
    Patent number: 7229174
    Abstract: A flashing dot is alternately shown in the left image and right display of a binocular device at short intervals so as to allow a user to detect the misalignment in the displays. If misalignment occurs, the user sees a dot moving between two locations. The user uses a device or a software program to move the dot for minimizing the apparent movement until a single stationary dot is observed.
