  2. Vernier acuity - Wikipedia

    en.wikipedia.org/wiki/Vernier_acuity

    A subject's vernier (IPA: / ˈ v ɜːr n ɪər /) acuity is the smallest visible offset between the stimuli that can be detected. Because the disalignments are often much smaller than the diameter and spacing of retinal receptors, vernier acuity requires neural processing and "pooling" to detect it. Because vernier acuity exceeds acuity by far ...

  3. Vernier scale - Wikipedia

    en.wikipedia.org/wiki/Vernier_scale

    The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale. So for a vernier with a constant of 0.1, each mark on the vernier is spaced 9/10 of those on the main scale.

  4. Hyperacuity - Wikipedia

    en.wikipedia.org/wiki/Hyperacuity

    Ewald Hering's model, published 1899, of how a Vernier acuity stimulus is coded by a receptor array. Receptors marked c signal a different position code along the horizontal direction from either the position a code or the position b code. [1] The sharpness of our senses is defined by the finest detail we can discriminate.

  5. Perceptual learning - Wikipedia

    en.wikipedia.org/wiki/Perceptual_learning

    Laboratory studies reported many examples of dramatic improvements in sensitivities from appropriately structured perceptual learning tasks. In visual Vernier acuity tasks, observers judge whether one line is displaced above or below a second line.

  7. Optimum HDTV viewing distance - Wikipedia

    en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance

    Also, there is the issue of vernier acuity, which is the eye's ability to detect an offset between 2 lines and stereoacuity, which is the ability to discriminate depth by the use of both eyes. Vernier acuity and stereoacuity are cited as being detected with only a 2–4 arc second degree of separation. [ 52 ]
