R. Bowen Loftin

R. Bowen Loftin (Richard Bowen Loftin) is an American physicist, computer scientist and university administrator who led early work on virtual environments for training at NASA's Johnson Space Center. In 1993 his group used a virtual environment to prepare members of NASA's ground-based flight team for the first Hubble Space Telescope servicing mission. He went on to direct the NASA/University of Houston Virtual Environments Research Institute, ran the Virginia Modeling, Analysis and Simulation Center at Old Dominion University, and later served as the 24th president of Texas A&M University and as chancellor of the University of Missouri.

Loftin received the IEEE Virtual Reality Career Award in 2008 and was named to the inaugural class of the IEEE VGTC Virtual Reality Academy in 2022.

Early life and education

Loftin was born in Hearne, Texas, and grew up in Navasota, about 20 miles from the Texas A&M campus. He attended Texas A&M University on a McFarland Physics Scholarship and finished his bachelor's degree in physics a year early, in 1970. At Rice University he earned an M.A. in physics in 1973 and a Ph.D. in physics in 1975, both under Harold E. Rorschach.

Career

Physics teaching and NASA training research

After a year as an assistant professor of physics at Texas A&M University at Galveston (1976-1977), Loftin joined the University of Houston-Downtown, where he taught physics from 1977 to 2000 and became a full professor in 1988. From May 1986 to December 2003 he was principal investigator for advanced training technologies in the Space Flight Training Division of the Mission Operations Directorate at the Johnson Space Center, directing research on intelligent computer-aided training, intelligent tutoring and virtual environment technology.

His early NASA research was in intelligent computer-aided training (ICAT). With Lui Wang, Paul Baffes and Grace Hua he built a system that trained Mission Control flight dynamics officers to deploy payload-assist module satellites from the Space Shuttle; it combined a user interface, a rule-based domain expert, a training session manager, a trainee model and a scenario generator. The four were granted U.S. Patent 5,311,422, "General purpose architecture for intelligent computer-aided training", on May 10, 1994. By 1992 Loftin and Robert Savely described ICAT systems that also used virtual environments and fuzzy logic.

Hubble Space Telescope flight team training

For the December 1993 Hubble repair and maintenance mission (STS-61), Loftin and Patrick Kenney's team built a virtual environment containing the telescope, the Space Shuttle payload bay and the fixtures that carried replacement hardware into orbit. Beginning in September 1993, about 100 members of NASA's flight team received more than 200 hours of training in it. The environment also modeled the most critical constraints of all major maintenance and repair procedures and, for the first time, was combined with a limited ICAT system that identified telescope features, monitored trainees' procedures in real time and intervened when they made errors. Loftin and Kenney described the project as the first large-scale implementation of virtual environment technology for training personnel for an actual mission.

Their paper says flight director John Muratore suggested the project. It was a joint effort of the Johnson Space Center's Software Technology Branch, the Space Flight Training Division and the Flight Director Office, and it aimed to teach flight controllers, engineers and technicians the location, appearance and operation of the telescope components. Six scenarios matched the mission's six primary spacewalks, covering tasks that included the COSTAR installation and the Wide Field/Planetary Camera changeout. Models were built with NASA's Solid Surface Modeler and Tree Display Manager tools and rendered with NASA software built on Silicon Graphics' Graphics Library; the system supported joysticks, magnetic trackers and a gesture glove. Development began in May 1993. Building the models exposed missing or inconsistent steps in some planned procedures, which were corrected before the mission.

In the post-mission survey published in IEEE Computer Graphics and Applications in 1995, flight team members judged on average that the virtual environment training had a positive effect on their job performance. Audio and visual cues helped, and the discomfort some trainees reported did not seriously hurt training transfer. The University of Houston's Virtual Environment Technology Laboratory reported that CyberEdge Journal gave the application a 1993 CJ Award and, in its March/April 1994 issue, listed it as the first virtual reality system used in training for a space mission.

Shared virtual environments and the University of Houston

From 1994 to 2000 Loftin was a professor of computer science at the University of Houston and director of the NASA/University of Houston Virtual Environments Research Institute. He also chaired the computer science department from 1999 to 2000. At NASA, his team was building the ability for several users to share one virtual environment, with changes to object positions and states sent to every site. The aim was to train international astronaut crews more cheaply and effectively in the early stages of mission preparation.

NASA, the University of Houston and the Fraunhofer Institute for Computer Graphics then tested a shared collaborative virtual environment across the Atlantic. On September 20, 1995, astronaut Bernard Harris at the Johnson Space Center and astronaut Ulf Merbold in Darmstadt, Germany, met in a virtual model of the Shuttle payload bay and the Hubble telescope. Over more than thirty minutes they reenacted the changeout of the telescope's Solar Array Drive Electronics, handing the replacement unit across in real time. Later work built a testbed of International Space Station module interiors with tracked, high-fidelity avatars whose arms were driven by fast inverse kinematics. With Office of Naval Research funding, a group that included the University of Houston, the University of Pennsylvania, George Mason University, LinCom Corporation and Lockheed Martin also developed a shared environment for training small military units at a peacekeeping checkpoint in a Bosnian setting.

Loftin also applied virtual reality to education. With Mark Engelberg and Robert Benedetti he presented a prototype virtual physics laboratory at the 1993 IEEE Symposium on Research Frontiers in Virtual Reality. In Project ScienceSpace, Loftin worked with Chris Dede and Marilyn Salzman of George Mason University on three immersive worlds covering Newtonian mechanics, electrostatics, and molecular structure and dynamics. The 1996 paper reported that its usability and learning results were not uniformly conclusive but suggested that students could improve their mastery of abstract concepts in virtual environments designed for learning. He also co-authored a 1995 paper on virtual reality in surgical education.

Old Dominion University

From August 2000 to May 2005 Loftin was a professor of electrical and computer engineering and of computer science at Old Dominion University in Norfolk, Virginia. He was also executive director of the Virginia Modeling, Analysis and Simulation Center and led the university's graduate programs in modeling and simulation. The peacekeeping research continued: a 2004 article by Loftin, Mark Scerbo, Frederic McKenzie and Jean Catanzaro applied virtual environments to training for military checkpoints and discussed differences between an immersive training system and a desktop version.

Texas A&M and University of Missouri

In May 2005 Loftin became a vice president of Texas A&M University and chief executive officer of its Galveston campus, where he was also a professor of maritime systems engineering. He became interim president of Texas A&M in June 2009 and president in February 2010. He stepped down on January 13, 2014, and became the 22nd chancellor of the University of Missouri's Columbia campus on February 1, 2014. While at Texas A&M he co-authored research with NASA Johnson Space Center scientists on cybersickness: a study presented in 2011 had 61 subjects complete sessions on three consecutive days in dome or head-mounted display virtual environments, found no significant main effect of device on sickness, and found that sickness severity decreased over the days. On November 9, 2015, amid campus protests and the resignation of University of Missouri System President Tim Wolfe, Loftin announced that he would step down at the end of the year and move to research work. Two days later the Board of Curators removed him from the chancellor's role immediately, and he became the university's director for research facility development. A 2024 Texas A&M Foundation profile described Loftin and his wife, Karin, as retired and active in philanthropy at Texas A&M.

Professional service

Loftin was general co-chair of the 1999 and 2000 IEEE Virtual Reality conferences and program co-chair of the 2002 and 2003 conferences. He served on the IEEE Virtual Reality steering committee from 1996, chairing it from 2009, and chaired the IEEE Computer Society Technical Committee on Visualization and Graphics in 2002 and 2003. With Lawrence J. Rosenblum he guest-edited a special issue of Presence: Teleoperators and Virtual Environments on the IEEE Virtual Reality 2002 conference. He also served on the editorial board of Presence, as senior editor from 2004 to 2006 and associate editor afterward.
