Embodiment Construction

[0067] In summary, the non-limiting exemplary embodiments of the present disclosure provide a head-mounted display (HMD) that improves user experience in the context of both virtual reality (VR) and mixed reality (MR). HMD is relatively light, ergonomically comfortable, and provides high-resolution content with low latency. HMD supports graphics content from an external computer equipped with a high-performance graphics processing unit (GPU) or graphics content from an embedded GPU, and by making the HMD perform some processing such as embedding in the case of correction of lens distortion and chromatic aberration Video pass-through and graphics / pass-through synthesis to ensure low latency to achieve low-latency MR. Position tracking, user body tracking, and environmental tracking are achieved through a unique inside-out method. For this unique inside-out method, all required tracking components are integrated in the HMD, thereby avoiding the need to set up and use external inp...

Abstract

A Head-Mounted Display system together with associated techniques for performing accurate and automatic inside-out positional, user body and environment tracking for virtual or mixed reality are disclosed. The system uses computer vision methods and data fusion from multiple sensors to achieve real-time tracking. High frame rate and low latency is achieved by performing part of the processing on the HMD itself.

Description

[0001] Cross reference to related patent applications [0002] This patent application claims the benefits of U.S. Provisional Patent Application No. 62 / 296,829 filed on February 18, 2016, which is incorporated herein by reference. Technical field [0003] The present invention relates to the field of head-mounted displays (HMD) for applications that immerse users in virtual reality (VR) or augmented / mixed reality (MR) environments. Background technique [0004] The goal of immersing in the virtual world is to persuade the user's mind to perceive the non-physical world as if the non-physical world is real. The concept of reality here refers more to the concept of perceptual plausibility, rather than the real world. In virtual reality (VR), immersion is achieved by displaying computer-generated graphics that simulate the visual experience of the real or imaginary world. The quality of immersion is limited by several important factors. For example, the characteristics of the displa...
