Abstract

A head mounted display is used in a state of being mounted on a user's head and includes a convex lens disposed at a position facing the user's cornea when the head mounted display is mounted. An infrared light source emits infrared light toward the convex lens. A camera captures an image including the user's cornea in a subject. A housing houses the convex lens, the infrared light source, and the camera. The convex lens is provided with a plurality of reflection regions that reflects infrared light in an inside of the convex lens. The infrared light source causes a pattern of infrared light to appear on the user's cornea by emitting infrared light to each of the plurality of reflection regions provided in the convex lens.
