The geometrical structure of binocular visual space and its relation to physical space is characterized by psychophysical invariances, i.e. physical transformations of the stimuli that leave perception invariant. The present paper investigates the invariance properties of the so-called iseiconic transformations postulated by Luneburg (1947). For a certain class of iseiconic transformations, the phi-shifts, predictions concerning the locus of the perceived midpoint in a bisection task can be derived. Five subjects participate in the respective experiment, in which perceived midpoints are determined by applying adaptive methods. For four out of the five subjects, however, there result systematic and statistically significant deviations from the postulated invariance. A generalization of the Luneburg theory is proposed that is capable of predicting the collected data, and provides a new characterization of the psychophysical invariances.
