AI Technical Summary

Problems solved by technology

Therefore, although the user's eyes are focused on the surface of the display screen, they converge on a position behind the screen surface corresponding to the position of the three-dimensional virtual object.
Since the vergence distance in this example is different from the focal length, the result is a vergence-accommodation conflict, which can cause discomfort, including visual fatigue and nausea

Embodiment Construction

[0030] The detailed description set forth below, in conjunction with the accompanying drawings, is intended as a description of various embodiments and is not intended to represent the only configurations or embodiments in which the concepts described herein may be practiced. These detailed descriptions include specific details to provide a thorough understanding of various concepts. It will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring these concepts.

[0031] Figure 1A with 1BIllustrates how the human eye experiences convergence and accommodation when looking at objects in the real world. Under typical conditions, when a person looks at a real object, the eyes focus to look at an object at a certain distance. When an object moves closer (for example, Figure 1B ) or away from (for example, Fig...

Abstract

The invention discloses single-sided board head-mounted display equipment. The single-sided board head-mounted display equipment comprises a display screen and an optical block; the optical block is configured to present a first shift version of a whole of an image generated by the display screen to a left eye of a user of the head-mounted display equipment at a moment; the first shift version ofthe image has a first perception center position that is different from the center of the display screen; and the optical block is further configured to present a second shift version of the whole ofthe image generated by the display screen to the left eye of the user of the head-mounted display equipment at the moment, and the second shift version of the image has a second perception center position that is different from the center of the display screen and different from the first perception center position.

Description

technical field [0001] The present invention relates to single-panel head-mounted displays. Background technique [0002] Head-mounted displays (HMDs) allow users to view images or video signals through a pair of glasses, goggles, or wearable headphones. The HMD can be used to simulate various virtual environments. For example, an HMD may include one or more electronic displays on which stereoscopic images can be displayed to simulate the illusion of depth and which can use head or eye tracking sensors to estimate which part of the virtual environment a user is looking at. [0003] Vergence is the simultaneous movement or rotation of a person's eyes in opposite directions to maintain a single binocular vision. The human eye performs convergence naturally and automatically. Accommodation is the process by which the eye changes its optical power to focus on an object as the distance between the object and the viewer changes. When a person views a real-world object, the loc...
