Embodiment Construction

[0042] The technical solution in this application will be described below with reference to the accompanying drawings.

[0043] The following key terms are involved in the embodiments of this application.

[0044] Retinal resolution: Retinal resolution is also known as human eye pixels. Pixel per degree (PPD) is the number of pixels that can be arranged per inch of length. The higher the number of pixels, the display screen can display images at a higher density. For headsets, achieving "retina resolution" is the ultimate goal. At a certain pixel density, even a person with perfect eyesight cannot make out any additional details. For visual quality, any screen higher than 60 pixels / degree is actually a waste, because the human eye can no longer discern any additional details, which is called the limit of the resolution of the human retina.

[0045] Head-mounted display screen pixels: Refers to the pixels contained in each degree of the screen of the head-mounted display de...

Abstract

The invention provides a virtual reality character display method and device and virtual reality equipment. The method comprises the following steps: receiving text information; determining the font size of the text information according to the degree pixel PPDVR equipment of the virtual reality VR equipment, the degree pixel PPD human eyes of the user eyes, the distance information between the text information in the VR and the user eyes and the correction value; rendering the text information according to the font size of the text information; and displaying the rendered text information. According to the pseudo-reality character display method provided by the invention, the problem of unclear character display in the current virtual reality environment can be solved, and the method canbe directly applied to various virtual reality platforms. Meanwhile, the problem that developers cannot quickly obtain various comfortable and readable font heights under different virtual environmentdistances in different VR devices in the virtual environment is solved. The user experience is improved and the development cost is reduced.

Description

technical field [0001] The present application relates to the field of virtual reality display, and more specifically, to a method, device and virtual reality device for displaying virtual reality text. Background technique [0002] Virtual reality (virtual reality, VR) is to use computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, so that users can experience real-time, unlimited Observe things in three-dimensional space. Display devices in VR hardware include VR head-mounted display (head-mounted display) devices. Binocular omni-directional displays, etc., users can obtain virtual reality effects about vision by wearing VR display devices. For example, a VR display device may include VR glasses, a VR helmet, and the like. [0003] At present, limited by the performance of VR hardware, users' eyes are tired and they cannot see the text or images in the VR scene clearly, which is th...
