Discovering that intensity of perceptual bias in specific views varies depending on posture

A research team led by Fumiaki Sato, a doctoral student at the Department of Computer Science and Engineering, Toyohashi University of Technology with the Japan Society for the Promotion of Science (JSPS) Research Fellowship for Young Scientists, and professors Shigeki Nakauchi and Tetsuto Minami discovered that the intensity of perceptual bias in specific views varies depending on the posture of the neck. This research investigated how changes in posture have a contextual effect on visual perception. Specifically, the experiment used the Necker cube as a visual stimulus that would potentially generate two different visual perceptions. In a virtual reality (VR) space, it placed the stimulus above and below each subject and asked them to report how it appeared in a posture that involved looking up at the stimulus and in another posture that involved looking down at it. The experiment revealed that the visual perception of the stimulus varied depending on the viewing posture.
