An afterimage vernier method for assessing the precision of eye movement monitors: results for the scleral coil
Vision Research
|January 1, 1985
Abstract:
A method is described to assess the precision of eye movement monitors by comparing the difference in two sequentially measured eye positions with the relative positions of afterimages that were induced at the same moments. A 0.1-0.3 min of arc sensitivity could be reached, using a vernier method. The precision of the scleral coil technique was 1 min of arc.
