1. A head mounted display comprising:
- an enclosure accommodating a presentation section adapted to present a three-dimensional image and located in front of the eyes of a viewer when worn on the head of the viewer; and
an imaging element provided in the enclosure and adapted to turn light external to the enclosure into an image, whereinthe imaging element images light that is vertically downward relative to the enclosure and forward in the direction of line of sight of the viewer when the enclosure is worn on the head of the viewer.

10. A motion detector comprising:
-
an image acquisition section adapted to acquire an image captured by an imaging element attached to the head of a user by imaging infrared light radiated by a light-emitting element that moves along with the motion of the user'"'"'s hand; a bright spot detection unit adapted to detect a bright spot of infrared light in the image captured by the imaging element; a vector acquisition unit adapted to acquire a vector having, as an end point, the bright spot detected by the bright spot detection unit, and, as a start point, the center of the image captured by the imaging element; a pitch acquisition unit adapted to acquire, as a pitch of the light-emitting element relative to the imaging element, the length of the vector acquired by the vector acquisition unit; and a yaw acquisition unit adapted to acquire, as a yaw of the light-emitting element relative to the imaging element, the declination of the vector acquired by the vector acquisition unit.

11. A motion detection method causing a processor to:
-
acquire an image captured by an imaging element attached to the head of a user by imaging infrared light radiated by a light-emitting element that moves along with the motion of the user'"'"'s hand; detect a bright spot of infrared light in the acquired image; acquire a vector having, as an end point, the detected bright spot, and, as a start point, the center of the image captured by the imaging element; acquire the length of the acquired vector; and acquire the declination of the acquired vector.

12. A program causing a computer to implement the functions of:
-
acquiring an image captured by an imaging element attached to the head of a user by imaging infrared light radiated by a light-emitting element that moves along with the motion of the user'"'"'s hand; detecting a bright spot of infrared light in the acquired image; acquiring a vector having, as an end point, the detected bright spot, and, as a start point, the center of the image captured by the imaging element; acquiring the length of the acquired vector; and acquiring the declination of the acquired vector.

13. An image presentation system comprising:
-
a head mounted display; and a light-emitting element attached to a grip section gripped by a viewer and adapted to radiate infrared light, wherein the head mounted display includes; an enclosure accommodating a presentation section adapted to present a three-dimensional image and located in front of the eyes of the viewer when worn on the head of the viewer; an imaging element provided in the enclosure and adapted to image infrared light radiated by the light-emitting element that moves along with the motion of the grip section; and a motion tracking section adapted to track the change in relative position of the light-emitting element with respect to the imaging element by analyzing the infrared light image captured by the imaging element.
