A unique method and a device to generate free space “pop-out” & “sink-in” holograms is disclosed herein. The hologram disclosed herein does not use any special medium, mirrors, reflective screens or wearables such as headgear & special glasses. The hologram disclosed herein can be created in free space, outer space or in air, without any other optical components except for the special display screen of the hologram device. This device demonstrates a free space hologram and the hologram Augmented Reality & hologram Virtual Reality. A camera capable of hologram quality images equipped with a smart lens which mimics the human eye by changing it's lens aperture according to the light intensity as the pupil of the human eye and focus & capture “pop-out” & “sink-in” hologram images is disclosed herein. The audio which is incorporated with the device provide multi dimensional multi directional audio effects.

Provided is a display device comprising a display panel having an array of display pixel elements for producing a display output; a viewer detecting system rendering data representing 1) the illumination intensity of a body part of the viewer and 2) another property of the body part; at least one illumination source for providing illumination of a body part of the viewer; and a processor configured to 1) process the data representing the illumination intensity of a body part of the viewer and 2) drive the at least one illumination source dependent on said illumination data to adapt the illumination intensity of a body part of the viewer.

A method for interacting with an autostereoscopic display is disclosed. The method includes initiating displaying by the autostereoscopic display a left eye view and a right eye view that contain a virtual manipulated object, determining a real-world coordinate of the virtual manipulated object perceived by a user located at a predetermined viewing position of the auto stereoscopic display, receiving an interactive action of the user's manipulating body acquired by a motion tracker, where the interaction action includes a real-world coordinate of the manipulating body, determining whether an interaction condition is triggered based at least in part on the real-world coordinate of the virtual manipulated object and the real-world coordinate of the manipulating body, and refreshing the left eye view and the right eye view based on the interactive action of the manipulating body acquired by the motion tracker, in response to determining that the interaction condition is triggered.
