Augmented reality head-mounted display device

Abstract

The invention discloses an augmented reality head-mounted display device which comprises a head band, glasses legs and an optical host, and the head band and the glasses legs are detachably connectedwith the optical host through plugging mechanisms; the optical host further comprises an optical path structure capable of inhibiting myopia deepening, optical defocusing is formed through a fixed-focus optical path and a zoom optical path, and myopia defocusing is enhanced to counteract myopia development; for a user suffering from hyperopia, the position of a negative lens group in the zoom light path can also be changed such that a background image is imaged behind the retina to control hyperopia deepening; the whole display device can be fixed through the glasses legs and the nose pads when used for a short time, the whole display device can be fixed through the head band when used for a long time, and the wearing structure not only guarantees the firmness of the device, but also givesconsideration to portability and comfort.

Description

technical field [0001] The invention belongs to the field of augmented reality equipment, and in particular relates to an augmented reality head-mounted display device. Background technique [0002] Augmented reality head-mounted display devices (referred to as "AR devices") can use computers to construct virtual objects and information in real scenes, allowing users to observe and explore impossible scenes, focusing on the interaction between virtual objects and the real world. Many companies have participated in the research and development of AR devices, such as Facebook's Oculus, Sony's Project Morpheus, Samsung's Gear, Microsoft's HoloLens, etc., but existing AR devices have security concerns. In order to improve the firmness of wearing, the existing AR equipment will have a support part on the forehead or the top of the head, and most of the support part is integrated with other structures of the device. If such an integrated support structure is to be able to respond ...

AI Technical Summary

Problems solved by technology

In order to improve the firmness of wearing, the existing AR equipment will have a support part on the forehead or the top of the head, and most of the support part is integrated with other structures of the device. If such an integrated support structure is to be able to respond to different users Personalized adjustment requires a complex adjustment structure, which increases the cost, increases the weight and wearing burden of the entire device, and reduces the user's comfort. At the same time, the threat of AR devices to eye health is also increasing. Long-term immersion Regular use, excessively bright screen, out-of-focus virtual objects and real scenes, etc. will all have a serious negative impact on the eyes, leading to myopia or myopia deepening
