Binocular fusion

Question 1

Solving correspondence problem

Answer 1

Binocular fusion, results in 3D image.

If this fails, you have double vision, one of the eyes is supressed or binocular rivalry

Question 2

Diplopia

Answer 2

Double vision, when fusion doesn’t occur. Can be because images are too different or too far away. Disparity is not small enough to create fusion

Question 3

Panum’s area

Answer 3

The region where disparity is small enough to result in fusion. I don’t have this. Objects outside this area result in double vision or suppression in one of the eyes.

Question 4

Floating finger sausage

Answer 4

illusion due to failed correspondence/fusion. Two images can’t be fused, causing the brain to interpret the fingers as a sausage

Question 5

Strabismus

Answer 5

Misalignment of the eyes. Due to:
- Congenital eye-muscle disorder
- Cranial oculomotor nerve disorder (neurological)

No part of the two images corresponds, resulting in double vision. If one eye is permanently suppressed: Amblyopia

Question 6

Binocular rivalry

Answer 6

Occurs when two images are completely different, only achieved experimentally using device to present different images to the two eyes. Perception switches between the two images, different duration of dominance for each stimulus.
