Stereoscopic acuity

Show Summary Details


The threshold of detection of a difference in depth on the basis of binocular disparity is known as stereoacuity. Under the best conditions, a depth interval of 4 mm can be detected at a distance of 5 m. This chapter starts with review of tests of stereoacuity. It goes on to discuss factors, such as contrast, color, spatial frequency, and eye movement that influence stereoacuity. Stereoacuity is compared with monocular acuities, such as vernier acuity, and the effects of stimulus duration and interocular delays are discussed. The chapter ends with a discussion of the effects of attention and learning on stereoacuity.

Keywords: stereoacuity; tests of stereoacuity; stereoacuity and eye movements; learning and stereoacuity
