Keynote Speaker
How the Social Network of Knowledge Leads to Scientific Truth
Science, as practiced since the Renaissance, can lead to true outcomes, as measured by the astounding growth in technology and prosperity since that time. How can this be, and why did it start at that time? For many centuries, this question has been explored by philosophers and historians. This talk will cover some of this history, and address puzzles such as:
-
No one person knows the truth, yet truth nevertheless emerges from scientific inquiry.
-
Philosophers cannot even cleanly define the concept of “truth”, yet truth nevertheless emerges from scientific inquiry.
-
In every field and sub-field of scientific knowledge and technology, complexity is ever growing, far beyond what any one person can comprehend, yet truth nevertheless emerges from scientific inquiry.
As one who uses empirical methods to pursue scientific inquiry, the speaker has found understanding some of this history to be helpful, especially when pondering the worth or meaning of conducting specific experiments.
Biography
Dr. J. Edward Swan II is a Professor of Computer Science and Engineering at Mississippi State University. He holds a B.S. (1989) degree in computer science from Auburn University and M.S. (1992) and Ph.D. (1997) degrees in computer science from Ohio State University, where he studied computer graphics and human-computer interaction. Before joining Mississippi State University in 2004, he spent seven years as a scientist at the Naval Research Laboratory in Washington, D.C. Dr. Swan’s research has centered on the topics of augmented and virtual reality, perception, data science, empirical methods, human-computer interaction, human factors, and visualization. Currently, he is studying the perception and technology required to give virtual objects definite spatial locations, including depth and layout perception and depth presentation methods. He is also studying efficient data science tools, and collaborating with social scientists to analyze social media data. His research has been funded by the National Science Foundation, the Department of Defense, the National Aeronautics and Space Administration, the Naval Research Laboratory, and the Office of Naval Research. Dr. Swan is a member of ACM, IEEE, and the IEEE Computer Society. He has served many roles in the technical communities of IEEE Virtual Reality (VR), IEEE International Symposium on Mixed and Augmented Reality (ISMAR), and IEEE Visualization. He is currently the chair of the IEEE VR steering committee. Previously, he served as one of the general chairs of VR 2021 and VR 2020, as well as a program chair for ISMAR 2017, ISMAR 2016, VR 2015, and VR 2014. He is also a member of the ISMAR steering committee. In 2017 and 2018, he served as Interim Department Head of Computer Science and Engineering at Mississippi State University.
Why PERCxR?
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 extended 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. Meanwhile, mobile platforms and emerging display hardware (“glasses”) promise to 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 applications, or even pose risks in their 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 in route to more usable application interfaces.
Themes and Topics
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 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

Instructions for Submission
1.
Submissions must be in PDF format, using the submission guidelines specified for ISMAR conferences. A committee of expert reviewers will review all submissions.
2.
Papers should be between 2 and 4 pages in length (excluding references).
4.
Papers must be submitted electronically through PCS. If you already have an account with PCS, please use that account to submit your paper. Otherwise, create a new account. Once therein, select the track titled "ISMAR 2021 PERCxR 2021" and click Go button.
3.
Papers must be submitted in English.
ISMAR uses a DOUBLE-BLIND review process. This means that both the authors and the reviewers must remain anonymous to each other. Submissions (including citations) must not contain information that identifies the authors, their institutions, funding sources, or their places of work. Relevant previous work by the authors must be cited in the third person to preserve anonymity. Authors should work diligently to ensure that their submissions do not expose their identities either through carelessness or intentionally. Authors that have questions/issues around the double-blind submission policy should contact the workshop chairs.
