Abstract: A measuring method for measuring rotation characteristics of an eyeball of a subject includes: showing display information on a display screen, at a position separated from a reference position, the display screen being shown in front of the eyeball of the subject by a display device that is secured to a head of the subject, the reference position being where a front line of sight of the eyeball of the subject who looks forward straightly, crosses the display screen; changing a direction of a line of sight from the eyeball to the display information by switching the display information to other contents while changing a displayed position of the display information; and judging whether the subject can recognize the contents of the display information at the changed position, to measure the rotation characteristics of the eyeball.
