Understanding Visual Confusion Using Stereoscopic Displays

Summary

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.

Conditions

• Diplopia
• Binocular Vision Suppression
• Binocular; Fusion, With Defective Stereopsis
• Monocular Diplopia

Interventions

BEHAVIORAL

Binocular visual confusion (unilateral opaque)

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).

BEHAVIORAL

Unilateral monocular visual confusion (unilateral see-through)

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).

BEHAVIORAL

Bilateral monocular visual confusion (bilateral see-through)

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).
