A METHOD AND AN APPARATUS FOR CHECKING THE THRESHOLDS OF A SUBJECT'S PERCEPTION OF VISUAL STIMULI

摘要

In a method of checking the threshold values of a subject's perception of visual stimuli, for each one of a selection of test series, the estimated error of a threshold value estimate of the test series is used to judge whether the test series is to be continued or not. This means that a test series may be discontinued as soon as the threshold value thereof can be determined with acceptable accuracy. Preferably, a posterior probability function is used for estimating the error. An apparatus for carrying out the method includes a control unit operating according to the method.
