We aim to democratize extended reality (XR) systems research, development, and benchmarking by providing
A reference open source end-to-end XR system testbed, with state-of-the-art components connected with a modular runtime
A benchmarking methodology for XR systems, including reference system configurations, applications, data sets, and metrics
A community where the multidisciplinary XR systems research and development stakeholders come together
We are excited to announce a new release of ILLIXR (ILLinois eXtended Reality testbed) v4.1 and our ISMAR/TVCG paper with the first open low power, low latency, and high fidelity scene reconstruction and delivery system for XR. This work is our next milestone in distributed XR – harnessing remote computation via wireless networking – to provide richer XR experiences with low power, comfortable XR devices.
Researchers leveraging the ILLIXR (Illinois Extended Reality) platform continue to explore new challenges in immersive computing. Their latest work introduces a lightweight headset-side defense against subtle adversarial drift in XR systems, advancing efforts toward more secure and trustworthy immersive computing.

The slides for the talk are available.
Tutorial on ILLIXR at ASPLOS on 3/30/25 from 8 am to 11:30 pm CST.
We are very excited to announce a major new release of ILLIXR (ILLinois eXtended Reality testbed) - a significant milestone towards our grand challenge goal of comfortable, mobile, all day, rich immersive experiences. The stringent power budgets of mobile and lightweight XR devices imply that not all immersive computations can be performed locally — remote offloading or Distributed XR is essential. ILLIXR v4.0 is the first open-source end-to-end XR system that supports offloading of both head tracking and rendering (with 6DoF reprojection in the runtime), either separately or together. This release also introduces several other major upgrades, including hand tracking, plugin support for ORB_SLAM3 integration, and a new network backend that enables the offloading of multiple components under the coordination of the runtime.
Get started with ILLIXR! We released several hands-on tasks for new students and developers interested in XR research and modular runtime systems.
Sarita Adve delivered a keynote speech at the Design Automation Conference (DAC) 2024, exploring the future of immersive computing. She shared groundbreaking insights and integrative research approaches designed to bridge the gap between current and desired immersive systems, aiming to foster a better world through technology.
