Head-mounted display device and method for controlling the same

Abstract

The invention provides a head-mounted display device and a control method thereof. The user experience can be improved. A first light ray propagation unit is arranged in the first supporting structure, and a second light ray propagation unit is arranged in the second supporting structure; the light reflected by the left eye is imaged on the image plane of the first detection unit through the first light propagation unit, and the light reflected by the right eye is imaged on the second detection unit through the second light propagation unit; when an image formed by the image surface of the first detection unit is different from a first preset position and an image formed by the image surface of the second detection unit is different from a second preset position, the adjusting unit adjusts the positions of the first and second supporting structures on the bearing structure; the measuring unit records the displacement of the first and second supporting structures; the control module determines an actual human eye interpupillary distance according to the displacement; based on the actual human eye interpupillary distance, the light emitted by the first display is collected by the left eye through the first light propagation unit; the light emitted by the second display is collected by the right eye through the second light propagation unit.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a head-mounted display device and a control method thereof. Background technique [0002] Electronic devices present image information such as text and images to users through displays, and can display pictures, play videos, and interact with users in games, etc. for users. For example, an augmented reality (Augmented Reality, AR) head-mounted display device can present images to a user through a display, giving the user an immersive experience. Specifically, since there is a certain distance between human eyes, the visual scenes seen by the left and right eyes are different. Based on this, in the stereoscopic projection imaging system, by displaying images having parallax for the observer's right and left eyes, it is possible to provide the observer with a 3D (three-dimensional) image that can be viewed three-dimensionally. [0003] However, when the interpupillary ...

Problems solved by technology

[0003] However, when the interpupillary distance of the left and right displays of the AR head-mounted display device does not match the interpupillary distance of the observer's right and left eyes, the observer may observe image distortion, which not only destroys the observer's experience, and can also cause problems such as eye fatigue or headaches for the observer
