DISPLAY DEVICE, HEAD DISPLAY, DISPLAY SYSTEM AND CONTROL METHOD FOR DISPLAY DEVICE Russian patent published in 2017 - IPC G06F3/01 

FIELD: physics.

SUBSTANCE: transmissive type display device is provided that allows a user to visually recognize a display screen as a virtual image and visually recognize a focal distance display screen that is consistent with the user convergence angle. The device comprises an object recognition section, a distance detection section, a display control section. The display control section controls the screen for displaying the image surrounding the actual object to direct the user's visual line to the convergence angle, which is consistent with the detected distance, on the display screen.

EFFECT: ensuring that the virtual object is perceived in the correct location relative to the real object due to the ability to adjust the user's convergence angle so that it corresponds to the detected distance between the user and the real object.
