Display control method and device, head-mounted display device and medium

By using the degrees of freedom information of the head-mounted display device to determine user needs, the terminal device is controlled to stop or reduce image data transmission, and the canvas display strategy is optimized. This solves the problems of resource waste and display chaos when multiple AR products are running simultaneously, and achieves resource conservation and latency reduction.

AI Technical Summary

⚠Technical Problem

When AR products run multiple applications simultaneously, the increased image data transmission leads to resource waste and high latency, and overlapping semi-transparent canvases cause display clutter.

⚗Method used

By using the degrees of freedom information from the head-mounted display device to determine user needs, the terminal device can be controlled to stop or reduce image data transmission, and the canvas display strategy can be optimized to solve the problems of resource waste and display clutter.

🎯Benefits of technology

It saves network resources, reduces latency, and solves the display chaos problem caused by overlapping different canvases in a semi-transparent state.

Abstract

The display control method and device, the head-mounted display device and the medium are provided. The method comprises the following steps: rendering image data of a first application on a first canvas in a desktop environment of a head-mounted display device; in the case that the first canvas is not displayed in a field of view range of the head-mounted display device, controlling a terminal device to stop transmitting to-be-transmitted image data of the first application; in the case that the first canvas is partially displayed in the field of view range of the head-mounted display device or the first canvas is blocked by a second canvas in the desktop environment, controlling the terminal device to reduce a data amount of the to-be-transmitted image data.
