Komine Lab
Machine-translated · View original
A lab that scientifically clarifies the effects of video on the viewer's experience.
AboutAbout the lab
Scientifically clarifying the effects of the video experience.
The Komine Lab, an NHK collaborative lab, studies what effects and influences video has on the people who watch it.
As new display devices such as smartphones, HMDs, and AR glasses become widespread, viewing styles have diversified, and the quality of the experience people get also differs from conventional TV viewing in the living room.
The lab aims to clarify what characteristics of video suit which display devices, and what conditions of a display device bring out those benefits, and to use the findings to support effective video production and the development of display devices.
The related fields are wide-ranging, including cognitive science, engineering, psychology, and physiology, and the lab pursues its research with flexible thinking that is not bound by field boundaries.
Key terms
- HMD
- Short for head-mounted display. A display device worn on the head to view video
- Semantic differential (SD) method
- One method of evaluating the impression a video makes, by having viewers answer a questionnaire
- Psychophysical experiment
- An experiment in which people who watch video perform a specific task, and their characteristics are examined from their responses
ResearchResearch themes
Video viewed on high-resolution displays or HMDs provides a strong sense of presence and immersion. This lab investigates the effects and influences of such video, aiming to apply the findings to supporting video production and developing display devices.
*Illustrative imageEvaluation techniques for measuring the quality of video viewing
The lab attempts to evaluate viewing quality by clarifying how people perceive the characteristics of video, based on their impressions and physiological indicators when watching it. In addition to impression evaluation such as the semantic differential (SD) method and psychophysical experiments, it estimates viewers' mental states through physiological measurements such as eye movements.
*Illustrative imageAutomatic generation of video expression suited to display devices
The lab is developing technology that clarifies the conditions of video expression suited to the characteristics of a display device and generates such video automatically. Based on the results of psychological experiments, it develops algorithms that derive appropriate virtual camera positions from the shapes and arrangement of objects placed in a CG virtual space.
