“…In this study, we investigated the perceived size and the perceived distance of virtual images in convex and plane mirrors. The perception of virtual images in mirrors is a sort of transformed vision that is comparable to vision under water (e.g., Adolfson & Berghage, 1974;Ono, O'Reiley, & Herman, 1970;Ross, 1968;Ross & Rejman, 1972;Vernoy, 1989;Vernoy & Luria, 1977) or to a specific optical device (e.g., Harris, 1965;Held & Gottlieb, 1958;Rock, 1966). However, interestingly enough, not much attention has been paid to mirror vision (Higashiyama, Yokoyama, & Shimono, 2001).…”

We investigated spatial perception of virtual images that were produced by convex and plane mirrors. In Experiment 1, 36 subjects reproduced both the perceived size and the perceived distance of virtual images for five targets that had been placed at a real distance of 10 or 20 m. In Experiment 2, 30 subjects verbally judged both the perceived size and the perceived distance of virtual images for five targets that were placed at each of five real distances of 2.5 -45 m. In both experiments, the subjects received objective-size and objective-distance instructions. The results were that (1) size constancy was attained for a distance of up to 45 m, (2) distance was readily discriminated within this distance range, although virtual images produced by the mirror of strong curvature were judged to be farther away than those produced by the mirrors of less curvature, and (3) the ratio of perceived size to perceived distance was described as a power function of visual angle, and the ratio for the convex mirror was larger than that for the plane mirror. We compared the taking-into-account model and the direct perception model on the basis of a correlation analysis for proximal, virtual, and real levels of the stimuli. The taking-into-account model, which assumes that visual angle is transformed into perceived size by taking perceived distance into account, was supported by an analysis for the proximal level of stimuli. The direct perception model, which assumes that there is no inferential process between perceived size and perceived distance, was partially supported by an analysis for the distal level of the stimuli.

“…The linear transducers of the inner ear require the central nervous system (CNS) to discriminate tilt and translation, and to delineate the appropriate compensatory reflexes. In general, the CNS correctly interprets natural movements during everyday life; however, this ability is compromised in patients with a dysfunctioning vestibular system 4 and in individuals working in complex 3-dimensional environments, such as the neutrally buoyant surroundings experienced by deep sea divers 5 , 6 and the altered acceleration fields faced by aviators 7 , 8 and astronauts 9 – 13 .…”

The effect of varying sinusoidal linear acceleration on perception of human motion was examined using 4 motion paradigms: off-vertical axis rotation, variable radius centrifugation, linear lateral translation, and rotation about an earth-horizontal axis. The motion profiles for each paradigm included 6 frequencies (0.01–0.6 Hz) and 5 tilt amplitudes (5°–20°). Subjects verbally reported the perceived angle of their whole-body tilt and the peak-to-peak translation of their head in space and used a joystick capable of recording 2-axis motion in the sagittal and transversal planes to indicate the phase between the perceived and actual motions. The amplitudes of perceived tilt and translation were expressed in terms of gain, i.e., the ratio of perceived tilt to equivalent tilt angle, and the ratio of perceived translation to equivalent linear displacement. Tilt perception gain decreased, whereas translation perception gain increased, with increasing frequency. During off-vertical axis rotation, the phase of tilt perception and of translation perception did not vary across stimulus frequencies. These motion paradigms elicited similar responses in roll tilt and interaural perception of translation, with differences likely due to the influence of naso-occipital linear accelerations and input to the semicircular canals that varied across motion paradigms.
