John O. Merritt
Senior Consulting Scientist
John Merritt is an internationally recognized expert in the operational use of
stereoscopic 3D displays and the application of research and development in sensory
and perceptual science to remote-presence systems. He brings his extensive practical
and theoretical knowledge of spatial perception and stereoscopic video applications
to every project.
John's early work in overhead reconnaissance as an Naval Air Intelligence Officer, combined with his years of experience as a 3D-display design consultant, make him uniquely qualified to assess the strengths and weaknesses of advanced 3D imaging systems.
John has extensive experience
comparing task performance in 3D vs. 2D evaluation studies. Since completing
his graduate work in sensory and perceptual psychology at Harvard University, he has
provided vision research and human factors engineering consulting services to a broad
range of industrial and government clients. As a senior research scientist at Perceptronics
in Woodland Hills, CA, he headed a number of R&D projects related to vision and visual-simulator
is the author of numerous technical reports and papers in the areas of vision research,
night vision devices (NVDs), evaluation of 3D systems for remote manipulation, image-quality
standards, visibility and illumination, 3D aerial photointerpretation, simulator displays,
highway safety, and visual fatigue. He has also served as a technical consultant and expert witness in patent litigation involving stereoscopic 3D systems.
John has been an active member of the Society of Photo-optical
Instrumentation Engineers (SPIE) since 1985. In 2012 he was elected a Fellow of the Society for his specific contributions to the field of stereoscopic displays and applications, and a Senior Member of the Society for his contributions to the SPIE organization. He is the founding chair of the SPIE/IS&T Conference on Stereoscopic Displays and Applications, which has run annually since 1990.
|John Merritt and Andrew Woods of Curtin University of Technology
co-teach a popular short course on stereoscopic displays and applications
at each annual SPIE conference. The course covers key principles and practices
essential for the design of successful stereoscopic display and imaging systems,
and includes demonstrations of leading-edge stereoscopic hardware. For the
full course description, see: www.stereoscopic.org/sc/index.html

John is a member of the Human Factors & Ergonomics
Society (HFES) and the HFES Forensics Technical Group, the Society for Information Display (SID), and the Association for
Unmanned Vehicle Systems International (AUVSI). He also sits on the Board of Directors of the Immersive Technology Alliance.
