Abstract: An optical module includes a lens barrel main housing, at least one dimming lens installed in the lens barrel main housing, a first cover assembly and a second cover assembly. Opposite ends of the lens barrel main housing are provided with a first opening and a second opening. The inner circumferential wall of the lens barrel main housing is provided with at least one limiting portion. Each dimming lens abuts against a limiting portion in the preset direction. The first cover assembly is arranged on the first opening and includes a light source configured to emit image beams to the at least one dimming lens. The second cover assembly is arranged on the second opening and includes a transparent component being capable of transmitting the image beams passing through the at least one dimming lens to an outside of the lens barrel main housing.

Abstract: 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.
