Psychophysical technique to measure the Just Noticeable Difference (JND) or the Point of Subjective Equality (PSE)

From EuroVR Knowledge Base

Description

Equality (PSE) The Just Noticeable Difference (JND) and the Point of Subjective Equality (PSE) are two parameters related to human perception. Classic psychophysical methods can evaluate: (1) the JND, i.e. the discrimination threshold which is an indicator of the user's perceptual performance and (2) the PSE which provides an indication of the possible perceptual bias introduced in the system. Interested people will easily find extended description of these techniques in many books and papers (see part bellow), and on the internet
