Steven M. LaValle is Professor of Computer Science and Engineering, in
Particular Robotics and Virtual Reality, at the University of Oulu,
Finland. He is a member of the Center for Ubiquitous Computing and the Faculty of Information Technology and Electrical Engineering. From 2001 to 2018, he was a professor in the Department of Computer Science at the University of Illinois. He has also held positions at Stanford University and Iowa State University. His research interests include robotics, virtual reality, sensor fusion, planning algorithms, computational geometry, and control theory. In research, he is mostly known for his introduction of the Rapidly
exploring Random Tree (RRT) algorithm, which is widely used in robotics
and other engineering fields. He also authored the books Planning
Algorithms, Sensing and Filtering, and Virtual Reality, all of which are available online for free (and published as paper books).
With regard to industry, he was an early founder and chief scientist
of Oculus VR, acquired by Facebook for $3 billion in 2014, where he
developed patented tracking technology for consumer virtual reality
and led a team of perceptual psychologists to provide principled
approaches to virtual reality system calibration, health and safety,
and the design of comfortable user experiences. From 2016 to 2017, he
was a Vice President and Chief Scientist of VR/AR/MR at Huawei
Technologies, where he was a leader in mobile product development on a
Challenges in Wireless XR
Virtual reality, and all of its cousins, works by designing perceptual illusions that trick the human senses. It can be considered as a form of perception engineering, because it is a human experience that is being engineered through artificial stimulation. In this area, there is a strong need for wireless, distributed computation because a wearable display should be as light as possible while avoiding wires that could ensnare the user. This talk will highlight some motivating use cases, which seem to require outrageously high performance from wireless networks. A key to the future may be to formulate network quality measures based on human perception in the context of virtual reality use cases. In this way, coding methods and network architectures are optimized around maintaining the desired engineered illusions, without network-induced side effects such as fatigue, nausea, and presence-destroying distractions.
