XRERROR

XRERROR is a term used in XR development to describe a class of runtime errors encountered in extended reality applications, including augmented reality (AR), virtual reality (VR), and mixed reality (MR). It denotes issues that affect user experience or system stability and can arise during rendering, input processing, spatial tracking, scene management, or device communication. XRERRORs are commonly emitted by runtime engines, middleware, and debugging tools to categorize and diagnose issues.

Common causes include misconfiguration of the XR runtime, outdated SDKs or drivers, resource loading failures (such as textures or meshes), shader compilation errors, tracking loss or stale pose data, camera permission issues on mobile devices, entitlements, and networked synchronization problems in multi-user experiences or incorrect world-space scaling. Error codes often follow a taxonomy such as XRERROR_GENERAL, XRERROR_RENDER, XRERROR_TRACKING, XRERROR_INPUT, XRERROR_RESOURCES, XRERROR_NETWORK, with accompanying messages and stack traces to aid debugging.

Handling and recovery involve recovering with fallbacks, degrading gracefully, pausing simulation when necessary, and presenting user-friendly error messages. Developers should collect telemetry with contextual information, reproduce steps, and verify compatibility with logs. It is important to keep runtimes and drivers up to date, confirm device permissions, calibrate sensors, and reinitialize subsystems as needed. Best practices include using consistent error codes, centralized logging, and thorough documentation to support debugging across XR platforms. This taxonomy helps developers diagnose cross-reality issues across environments.
