Abstract
In this work the change of the contrast detection threshold with eccentricity were measured for a range of eccentricities from 0 to \(27^\circ \). A common approach used for such measurements is to display a flashing stimulus presented by a fraction of a second in the observer’s peripheral viewing area. This condition prevents the registration of the results after unintended moving the eyes towards the stimulus and lowering the recorded thresholds. In contrast to this methodology, our stimuli are not modulated over time. We display stimuli continuously and use eye tracker to control the observers’ gaze direction. We prove that results of the psychophysical experiments based on this approach are consistent with the previous work.
