OpenXR Spatial Entities Extensions Drive Interoperable XR
The Khronos Group’s OpenXR framework has received a meaningful upgrade, promising to streamline the development of extended reality (XR) applications. The update introduces new Spatial Entities Extensions designed to foster standardization across XR-ready devices. This move arrives as Google’s AndroidXR operating system gains traction as a versatile framework supporting various XR applications and hardware from diverse manufacturers.
New Spatial Entities Extensions Enhance OpenXR
The Spatial Entities Extensions, now available via public review, equip the OpenXR operating system with enhanced support for interoperable XR spatial experiences. These extensions address a critical need within the developer community by offering a discoverable and extensible set of functionalities. According to Ron Bessems, Chair of the OpenXR Working Group, the extensions lay “a firm foundation for spatial applications today, and enabling continued innovation in portable spatial computing into the future.”
These new features provide consistent cross-platform support for detecting and tracking planes and markers, establishing precise spatial anchors, and ensuring cross-session persistence. all these improvements are specifically tailored for the rapidly expanding XR hardware market.
key features of the OpenXR update
The updated OpenXR API empowers developers to detect and track features within a user’s physical habitat. It also facilitates the precise positioning and anchoring of virtual content relative to these real-world features. This includes ensuring that virtual content persists across different XR device sessions, enhancing the continuity of user experiences.
By standardizing the spatial computing API, OpenXR significantly reduces both development time and associated costs. This standardization eliminates the need for developers to write device-specific code for each platform. Instead, developers can concentrate on creating innovative features rather than managing platform-specific implementations.
Praveen Babu J D, an engineering leader at ByteDance’s PICO, emphasized PICO’s contribution to the design and implementation of the OpenXR Spatial Entities Extensions. He stated that this core capability enables developers to build more persistent, shareable, and spatially aware XR experiences across various platforms.
AndroidXR: Google’s Vision for the future of XR
Google introduced AndroidXR, an operating system tailored specifically for extended reality, just late last year. At the time, the company underscored the importance of Gemini AI assistants in improving user interactions with headsets and enhancing the overall visual experience.
Built upon the familiar Android foundation, the XR operating system is designed to support both existing mobile and tablet applications, in addition to content created specifically for AndroidXR. This addresses a significant barrier to XR adoption: providing users with a diverse range of applications and engaging services to justify investments in XR devices.
AndroidXR aims to advance the future of artificial intelligence, augmented reality, and virtual reality experiences on headsets and smart glasses. Currently in a developer preview stage, a wider release is anticipated in the future.
According to Shahram izadi, the leader of Google’s AndroidXR development team, Google is collaborating with Samsung and Qualcomm to develop new Gemini AI use cases for emerging XR devices, including the upcoming Moohan headset. The Moohan headset from Samsung is expected to be available later this year.
The Convergence of OpenXR and AndroidXR
With OpenXR focusing on driving interoperable XR developments, the foundation for a true Android-powered XR ecosystem is solidifying. The collaboration promises a future where XR experiences are more accessible, standardized, and innovative.
The standardization of the spatial computing API significantly reduces development time. Also,it reduces costs,allowing developers to focus on innovation. This ultimately leads to more engaging and immersive XR experiences for end-users.

OpenXR: Powering cross-Platform XR Development
The world of Extended Reality (XR), encompassing Virtual Reality (VR) and Augmented Reality (AR), is rapidly evolving. At the heart of this evolution lies OpenXR,a royalty-free,open standard designed to unify and streamline the development of XR applications. This article delves into OpenXR’s capabilities, benefits, and its crucial role in fostering a truly cross-platform XR ecosystem. Keywords like VR development, AR applications, XR standards, cross-platform compatibility, and OpenXR API will guide our exploration.
what is OpenXR? – Core Concepts
OpenXR acts as an API (Application Programming Interface) that allows developers to wriet XR applications that can run on multiple hardware platforms without meaningful modification. Think of it as a bridge between the application and the myriad of VR and AR devices available. It simplifies the development process by abstracting away the hardware-specific complexities.
- standardization: OpenXR provides a standardized way for applications to interact with XR devices,ensuring consistency across different platforms.
- Interoperability: Applications built with OpenXR can run on a wide range of hardware, including VR headsets (like Meta Quest, HTC Vive, and Valve Index) and AR devices (like Microsoft HoloLens). XR compatibility is a key advantage.
