Ken Nakayama · American journal of optometry and physiological optic · 1978
ABSTRACT A new method of determining the primary direction of regard, using Listing's law as a basis, is described. Previous techniques have required a trial‐and‐error experimental procedure. The present technique requires only a single measurement set of eye torsions in selected gaze directions. Experimental data to illustrate the technique are presented.
