23rd or 24th of March in Arles, Camargue, Provence, France
In conjunction with IEEE Virtual Reality 2015

The IEEE VR 2015 Workshop on Perceptual and Cognitive Issues in AR 
(PERCAR) is intended to advance the state-of-the-art in human factors 
driven research in Augmented Reality.
The goal of this workshop is to come to a better understanding of the 
various perceptual and cognitive issues that affect 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 
display hardware (e.g., Google glass and competing displays with similar 
form factors) are leading an explosion in the number of users, as well 
as duration of system usage. To fulfill usability needs, a thorough 
understanding of perceptual and intertwined cognitive factors is highly 
needed by both the research community and industry: issues such as depth 
misinterpretation, object relationship mismatches, and information 
overload can severely limit usability of applications, or even pose 
usage risks. Based on the gained knowledge, new interactive 
visualization and view management techniques can be iteratively defined, 
developed and validated, and optimized for the identified effects to 
create more usable applications. 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.

Topics and submission
Papers should be between 4 and 6 pages in length and may cover one or 
more of the following topics:

· Depth perception in AR
· Color perception issues
· Issues related to visual search / information processing
· Novel capturing and processing techniques (like HDR) that address 
perceptual issues
· Comparisons between AR and VR perceptual issues
· Cognitive load or other cognitive issues related to perception
· Multisensory issues (perception 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
· Techniques for conducting longitudinal studies

Submitted papers will be evaluated through a double blind reviewing 
process of the submissions by the PC committee members. We will target 
the inclusion of papers into the IEEE Digital Library.

Blind submissions should be made through the Easychair system: a link 
will be made available at the workshop website at
