Abstract
A method for measuring perception of an observer comprises a) selecting a first, second, and third stimulus and presenting the stimuli to the observer; b) determining observer-defined fourth stimulus such that the observer perceives the fourth stimulus to be related to the third stimulus in the same way as the observer perceives the second stimulus to be related to the first stimulus; c) selecting a new first, second, and third stimulus, at least one of the new stimuli corresponding to a stimulus point that is different from the stimulus points corresponding to the previously selected stimulus; d) determining a new observer-defined fourth stimulus such that the observer perceives the new fourth stimulus to be related to the new third stimulus in the same way as the observer perceives the new second stimulus to be related to the new first stimulus; and e) performing steps (c) through (d) until a predetermined number of sets of four stimuli are determined.
