Dear all,

You and your students are cordially invited to our MAT seminar in the
spring quarter 2015.

The coming Monday on May 4, 2015, 12pm-1:30pm, at Engineering Science
Building, Room 2001, we have:

James Oliver. Professor at Iowa State University of Science and Technology
(ISU)

This event is open to public, coffee will be served. Please join us and
spread the word!

*Speaker*: James Oliver

*Abstract: *Monitor-based augmented reality interfaces are finding
increasing utility many manufacturing industries, due to their low cost,
relatively simple implementation, and ability to support multiple users.
However, while effective for relatively far field-of-view applications,
monitor-based AR systems cannot provide natural visual perception because
they present only a single monoscopic view of the physical and virtual
world. This talk presents new image processing and computer graphics
techniques that enable the incorporation of precise view-dependent
rendering and visual-spatial cues into monitor-based AR.

The fundamental innovation enabling this new AR interface is the
incorporation of head tracking and a video camera that captures the
workspace from its reflection from a spherical mirror. The spherical mirror
provides an omnidirectional reflection of the environment, and the video
camera captures a spherical image that encompasses the entire desktop and
its surroundings. Using the head and monitor positions, a sub-image from a
video frame can be identified that corresponds to the user’s view of the
desktop, and then processed to remove spherical distortion and correlate it
precisely to the users perspective view. In parallel, the same viewing
transformations derived for video image processing are used to render
virtual objects from the same viewpoint and these are dynamically
composited with the video to produce the desired AR effect. To simulate
monocular depth cues including, motion parallax, perspective, and shadows,
a depth map is generated from a sequence of video images. The depth map is
used to generate image warping by non-affine transformation and impostors
to realize the depth cues.

The goal is to realize the proprioceptive fidelity afforded by head-tracked
stereoscopic head-mounted display (HMD)-based AR within a monoscopic
monitor-based system. The result is a new AR interface for desktop
applications that provides natural visual perception at a higher level of
immersion (in terms of field of view and resolution) than HMD-based
systems, yet without their cumbersome usability and ergonomic implications,
and, at a much lower cost.

*Bio: *James Oliver holds the title of University Professor at Iowa State
University of Science and Technology (ISU) and serves as Larry and Pam
Pithan Professor of Mechanical Engineering. He is Director of ISU’s Virtual
Reality Applications Center (VRAC) – an interdisciplinary research center
focused on emerging interface technologies serving 40 faculty, 160 graduate
and 120 undergraduate student researchers. Professor Oliver also directs
ISU’s Interdepartmental Graduate Program in Human Computer Interaction
(HCI) that complements the VRAC’s research mission by providing PhD, MS,
and Professional Certificate degrees in HCI, with more than 200 students
currently enrolled. At the VRAC, Oliver recently led fund raising,
technical specification, and management of a $5M upgrade to the C6 – now
the world’s highest resolution (100M pixel) fully immersive VR room.

Professor Oliver’s research, teaching and economic development activities
span a wide array of emerging interface technologies, encompassing computer
graphics, geometric modeling, virtual and augmented reality, and
collaborative networks for applications in product development,
manufacturing and complex system operation. He is an internationally
recognized expert with more than 25 years of academic and industrial
experience, and over 100 papers published in peer-reviewed conferences and
journals. Through the course of his career, has secured more than $27M in
funding to support his research from federal sources including NSF, NASA,
ONR, AFRL, the US Army, as well as numerous industrial sponsors, and has
advised 15 PhD and 60 MS graduates.

>From 1997-2000 Oliver headed product development for Engineering Animation
Inc. (NASDAQ:EAII, now part of Siemens PLM), where he led the creation of a
unique Internet-based visual collaboration tool for supply chain
integration. He also served as Vice President of Product Development at
Cognicity, Inc. a Minneapolis-based startup focused on Internet-based
entertainment marketing. More recently, Professor Oliver co-founded
BodyViz, a high technology startup focused on low cost, easy to use medical
visualization with sales in the medical, education, veterinary and legal
markets.

Professor Oliver received his Ph.D. from Michigan State University in 1986.
He is a Fellow of the ASME, holds three U.S. patents, and is the recipient
of numerous professional honors and awards.
