Welcome to IEEE Workshop on Perceptual and Cognitive Issues in xR (PERCxR)

Informing the design of xR systems

Welcome to the online home of the IEEE Workshop on Perceptual and Cognitive Issues in xR (PERCxR). The 8th annual PERCxR (formerly PERCAR) workshop will be held as part of the online IEEE VR 2022 conference in March 2022.



Due to the compressed timeline of IEEE VR 2022, in combination with the fact that PERCxR was held in October 2021 at the ISMAR conference, we will not be soliciting or publishing papers as part of PERCxR at IEEE VR 2022.

Instead, we will be inviting speakers based on abstracts. We are especially interested in featuring talks from students, early career researchers, and researchers from historically underrepresented backgrounds and communities. Please don't hesitate to get in touch if you are interested in participating.

Abstract submissions are due by 11:59pm on Friday 28 January 2022 AOE. Abstracts will be used both for determining whether your topic is appropriate for the audience of PERCxR and for promoting your talk on the website leading up to the workshop. Please submit your abstracts via email to


PERCxR Overview

Informing the design of xR systems

The IEEE VR 2022 Workshop on Perceptual and Cognitive Issues in xR (PERCxR) will be the eighth installment of the successful workshop series hosted by the IEEE VR conferences 2015-2020 and at the IEEE ISMAR symposium in 2021.

The goal of this workshop is a better understanding of the various perceptual and cognitive issues that inform and constrain the design of effective and usable virtual, augmented, and mixed reality systems. There is neither an in-depth overview of these factors, nor well-founded knowledge on most effects as gained through formal validation. In particular, long-term usage effects are inadequately understood. Mobile platforms and emerging head-worn display hardware (“glasses”) are dramatically increasing the number of users, as well as the system usage duration. To fulfill usability needs, a thorough understanding of perceptual and intertwined cognitive factors is needed by both research and industry: issues such as depth misinterpretation, object relationship mismatches and information overload can severely limit usability of xR applications, or even pose risks to their users. Based on the knowledge generated by this workshop, we hope to inform the design and development of new techniques and systems optimized to be congruent with human capabilities and limitations.
