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.)

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.
