Due to concern that current U.S. Air Force depth perception standards and test procedures may not be adequate for accurately identifying aircrew medically fit to perform critical depth perception tasks during flight, the U.S. Air Force School of Aerospace Medicine developed a stereoscopic simulation environment to investigate depth perception vision standards. The initial results of this research showed that while the use of stereoscopic displays clearly improved performance for a helicopter landing task involving depth judgments, an individual's stereo acuity was not predictive of performance. However, landing task performance could be predicted when stereo acuity was used together with binocular fusion range. However, motion perception was a better predictor of performance than stereo acuity. Potential implications for medical vision standards and the potential complexities involved in predicting real-world performance based on performance in a stereoscopic flight simulation are discussed.

  • 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.
