Question

Monocular rivalry occurs due to the brain trying to concentrate on _________

(a) two equal displays on both the eyes

(b) two different displays on both the eyes

(c) one eye with display and the other eye without display

(d) both the outside world image and the displayed image in one eye

The question was asked in an interview for job.

The query is from Helmet Mounted Displays topic in section Displays and Man-Machine Interaction of Avionics

Answer 1

The correct answer is (c) one eye with display and the other eye without display

To explain: Monocular rivalry occurs because the brain is trying to process different images from each eye and rivalry can occur between the eye with a display and the eye without a display. The effect is most significant when flying at night when one eye sees less light whereas the other eye sees more. To overcome this binocular system is used where both the eyes are presented with the flight parameters.
