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  PERCxR (formerly PERCAR) workshop will be held once again as part of IEEE ISMAR 2022 in October 2022. (ISMAR will be a hybrid symposium this year, but PERCxR will be held online.)



We are once again inviting short (2-4) papers for consideration for the PERCxR workshop to be held in October 2022 as part of IEEE ISMAR. The submission deadline is Friday 29 July at 11:59pm AoE; for full details, please see the CFP document linked below.

We expect researchers to submit early work, such as initial analyses of user studies or experimental visualization techniques, although position papers that comprise several pages and summarize a range of previous experiments or experiences (survey) also fall inside the scope of the workshop.

Papers should be between 2 and 4 pages in length (excluding references) and may cover one or more of the following topics:

Depth perception in AR

Color perception issues

Issues related to visual search / information processing

Situational awareness

Studies related to selective, focused or divided attention

Just noticeable differences, signal thresholds, and biases

Individual differences in perception & cognition

Comparisons between AR and VR perceptual issues

Cognitive load, mental workload or other cognitive issues related to perception

Multisensory issues (sensation, perception & cognition in non-visual AR)

Visualization techniques addressing perceptual or cognitive issues

View management techniques

Novel visual display devices that target specific perceptual issues

Validation methodologies, benchmarks and measurement methods, including eye tracking

Novel capturing and processing techniques (like HDR) that address perceptual issues

Techniques for conducting longitudinal studies


Submitted papers will be evaluated through a double blind reviewing process of the submissions by the PC committee members.

Blind submissions should be made through the PCS system at:


PERCxR Overview

Informing the design of xR systems

The IEEE ISMAR 2022 Workshop on Perceptual and Cognitive Issues in xR (PERCxR) is the seventh installment of the previous successful PERCAR workshops held at the IEEE VR conferences 2015-2020, and the PERCxR workshops held at IEEE ISMAR 2021 and IEEE VR 2022

The crux of this workshop is the creation of a better understanding of the various perceptual and cognitive issues that inform and constrain the design of effective augmented 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. However, mobile platforms and emerging head-worn display hardware (“glasses”) ignite 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 highly needed by both research and industry: issues such as depth misinterpretation, object relationship mismatches and information overload can severely limit usability of AR applications, or even pose risks on its usage. Based on the gained knowledge, for example new interactive visualization and view management techniques can be iteratively defined, developed and validated, optimized to be congruent with human capabilities and limitations en route to more usable AR application interfaces.
