stereogramsgained

Stereogramsgained is a term used in visual perception research to denote a quantified improvement in stereoscopic depth judgments when disparity gain is applied to stereograms. It describes how increasing disparity gain—the factor by which binocular disparities are scaled—can enhance the salience of depth cues in a random-dot or texture-defined stereogram. In practice, stereogramsgained is measured by comparing task performance with a baseline display and with a gain-adjusted display. Common metrics include depth-accuracy, discrimination thresholds (JNDs) for depth, response times, and error rates. The gain parameter is typically denoted by g, where 1.0 represents no change, 1.5 and higher amplify disparities, and excessively large values can introduce binocular discomfort or unnatural depth.

The concept is relevant to calibration of stereoscopic displays, virtual reality, and assistive devices intended to aid depth perception. It is especially studied in contexts where users differ in sensitivity to disparity or where display technology introduces nonuniform disparities. Researchers may report stereogramsgained as a percentage improvement or as a gain factor at which performance plateaus or deteriorates.

Limitations include individual variability, risk of visual discomfort, and the possibility that gains reflect perceptual strategies rather than veridical depth. Stereogramsgained is thus a descriptive, application-oriented metric rather than a universal standard.
