As soon as “serious” conclusions (with respect to reality) have to be drawn from virtual reality experiences (training, virtual prototyping…), it is now more and more acknowledged that, besides display calibration and computer graphics issues, some attention has
to be given to perceptual calibration, on the human side. This paper presents results from recent experiments that extend previous data on speed perception during driving simulation. They show 1) that the manipulation of the position of the rendering (virtual) camera strongly influences the
drivers' speed perception, by transforming the optical flow pattern and 2) that this manipulation remains unnoticed by the driver and does not impact his/her attitude toward the simulation. They suggest that the position of the driver's viewpoint, with respect to the simulation screen,
is of critical importance for the calibration of ecologically valid simulation systems. More generally they emphasize the fact that perceptual calibration is fundamental in “serious” virtual reality applications.

For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.
Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
