Document Type and Number:
WIPO Patent Application WO/2021/065170
Kind Code:
A1
Abstract:
The present invention provides a binocular function measuring method comprising: a target presenting step for presenting, to a subject in a space in which real space information is blocked, a right-eye image to be visually recognized by the right eye of the subject and a left-eye image to be recognized by the left eye of the subject; a presentation control step for relatively changing the presentation positions of the right-eye image and the left-eye image; a timing detection step for detecting a timing at which the subject becomes unable to fuse the right-eye image and the left-eye image when the presentation positions are changed; and a parameter value calculation step for, on the basis of a relative positional relation between the right-eye image and the left-eye image when the timing has been detected, calculating a predetermined parameter value regarding the binocular function of the subject.
