In this research study we want to test how people understand a visual scene when the same image is presented to both the eyes, but portions of these images are altered in terms of contrast, depth or in some cases motion.

The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation. For the binocular visual confusion condition, the non-transparent (opaque) peripheral target will be displayed on only one eye (unilateral opaque display).
The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation. For the unilateral monocular visual confusion condition, the half-transparent peripheral target will be displayed on only one eye (unilateral see-through display).

Percentage of Total Viewing Time That Peripheral Target is Perceived
(Total time the peripheral target in the visual confusion condition was visible) / (total viewing time (=1 min))
Time frame: Approximately 1-2 sessions to finish total 6 trials, up to 2 hours for each session, any time within the 4month study period

The peripheral target was a horizontally drifting grating measuring 10° by 10°, with a spatial frequency of 1 cycle per degree and a temporal frequency of 3 Hz, and located at 10° above the fixation. For bilateral monocular visual confusion condition, the half-transparent peripheral target will be displayed on both eyes (bilateral see-through display).
