Extended-reality rendering using hardware pixels-per-degree estimations, and systems and methods of use thereof

A method of improving rendering of an XR device, the method comprising:

• determining an HPPD metric for the XR device based on a characteristic of a display device of the XR device and a characteristic of a lens of the XR device;
• receiving data regarding visual XR content from an XR application running on the XR device, the data comprising a size of the visual XR content and a location of the visual XR content;
• determining an RPPD metric for the visual XR content based on the data;
• determining a scaling factor for rendering the visual XR content based on the HPPD metric and the RPPD metric;
• determining a recommended resolution for the XR application based on the scaling factor;
• and
• transmitting the recommended resolution to the XR application, wherein the XR application is configured to render the visual XR content using the recommended resolution.

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of an XR device that includes a display device and a lens, cause the XR device to:

• determine a hardware pixels-per-degree HPPD metric for the XR device based on a characteristic of the display device and a characteristic of the lens;
• receive data regarding visual XR content from an XR application running on the XR device, the data comprising a size of the visual XR content and a location of the visual XR content;
• determine a render pixels-per-degree RPPD metric for the visual XR content based on the data;
• determine a scaling factor for rendering the visual XR content based on the HPPD metric and the RPPD metric;
• determine a recommended resolution for the XR application based on the scaling factor;
• and
• transmit the recommended resolution to the XR application, wherein the XR application is configured to render the visual XR content using the recommended resolution.
