Various researches identified that the main factors causing visual discomfort from watching 3D video are Vergence-Accommodation linkage conflicts, contrast changes, and some other defects in 3D display. In this paper, we propose a new method to lessen the visual discomfort by reducing blue-light components, which are highly sensitive to human eyes in 3D video. In our experiments, 20 people (9 male, 11 female) participated in watching four 15-minute original and blue-light reduced modified 3D videos, respectively. We surveyed perceived symptom questionnaires before and after watching videos, and measured the participant s eye-blink rates, saccadic movements, and near point of convergence (NPC). Our experimental results demonstrated that the eye-blink rate of the participant was lower in watching the blue-light reduced videos, while saccadic movements of the subject was higher in blue-light reduced videos compared to the original videos. Since eye-blink rate is usually increased when subject s eyes are dried, and slower eye movements are occurred due to tiredness, the blue-light reduced video caused smaller visual discomfort than the original video. Based upon NPC and perceived symptom questionnaires, we confirmed that viewers indeed feel more comfortable watching the blue-light reduced video compared to the original video.

  • 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.
