Postural Perceptions and Compensatory Displacements of the Eye in Respect to a Presented Force Field: Synchronous Three-Orthogonal Registration

Abstract

The method described allows qualitative and quantitative registration along three axes (X, Y and Z) of the apparent change in space of an observed object, watched by an individual, deprived of visual references while he is subjected to force fields of varying direction and of varying magnitude. By means of a synchronous infrared filming technique, it is also possible at each moment of the procedure to determine with good approximation the directional changes of the eye in the same three axes, and thus to correlate them with the recorded perceptions. The validity of the various parts of the produce is subjected to critical appraisal.
