ILLIXR: An Open Testbed to Enable Extended Reality Systems Research

April 1, 2022 1:00 PM – 2:00 PM via Zoom

Speaker: Muhammad Huzaifa, University of Illinois at Urbana-Champaign, USA


Extended reality (XR), including augmented, virtual, and mixed reality (AR/VR/MR), has the potential to transform our lives, but there is an orders of magnitude performance-power-quality gap between what is achievable today and our ideal XR systems. To enable research and development in this area, we have built ILLIXR – Illinois Extended Reality tested – the first open source XR system and testbed for XR systems research and development. Using ILLIXR, we have provided the first published results on performance/power/quality of an end-to-end XR system. These results show that systems of the next decade require, and ILLIXR enables, application-driven, end-to-end quality-of-experience driven, and hardware-software-application co-designed systems research. We have also launched the ILLIXR consortium, an industry backed consortium to democratize XR systems research, development, and benchmarking by creating a reference XR testbed based on ILLIXR, a benchmarking methodology, and a multidisciplinary XR systems research community. In this talk, we will describe ILLIXR, results from ILLIXR, the many research projects that ILLIXR is enabling, and the ILLIXR consortium.


Muhammad Huzaifa is a PhD candidate in Computer Science at The University of Illinois at Urbana-Champaign where he works with Professor Sarita Adve on systems and architectures for Extended Reality. Together with his advisor, he leads the ILLIXR project and co-chairs the ILLIXR consortium. He is a recipient of an IEEE Micro Top Picks, an IISWC Best Paper Award, the Sohaib and Sara Abbasi Computer Science Fellowship, a Feng Chen Memorial Award, and an Outstanding Teaching Assistant award. He has a Bachelor of Engineering in Computer Engineering from McGill University.
