Abstract

A head mounted display device is used by being mounted on a body of a user and includes an image display unit through which outside scenery is transmitted and that displays an image such that the image is visually recognizable together with the outside scenery. Further, the head mounted display device includes a target detection unit that detects a target of the user in a visual line direction and a position detection unit that detects a position of the target with respect to a display region of the image display unit. Further, the head mounted display device includes an information display control unit that determines a display position of information based on a position of the target detected by the position detection unit and allows the image display unit to display information.

Claims

1. A display device which is used by being mounted on a body of a user, comprising:

a display unit through which outside scenery is transmitted and that displays an image such that the image is visually recognizable together with the outside scenery;

a target detection unit that detects a target of the user in a visual line direction;

a position detection unit that detects a position of the target with respect to a display region of the display unit; and

an information display control unit that determines a display position of information based on the position of the target detected by the position detection unit and allows the display unit to display information.

2. The display device according to claim 1, further comprising an imaging unit that images the visual line direction of the user,

wherein the target detection unit detects the target that is visually recognized by the user through the display unit based on a captured image of the imaging unit.

3. The display device according to claim 2, wherein the position detection unit detects the position of the target based on the captured image of the imaging unit.

4. The display device according to claim 3, wherein the position detection unit detects the position of the target based on a plurality of pieces of information including the captured image of the imaging unit.

5. The display device according to claim 1, wherein the information display control unit allows the display unit to display additional information related to the target detected by the target detection unit.

6. The display device according to claim 1, wherein the position detection unit detects a position in which the user visually recognizes the target through the display region of the display unit.

7. The display device according to claim 6, wherein the information display control unit allows information to be displayed such that the display region is overlapped with the position of the target detected by the position detection unit.

8. The display device according to claim 1, further comprising a distance detection unit that detects a distance between the target and the user,

wherein the information display control unit determines a display mode of information and allows the display unit to display the information in a determined display mode according to the distance detected by the distance detection unit.

9. A method of controlling a display device which includes a display unit through which outside scenery is transmitted and that displays an image such that the image is visually recognizable together with the outside scenery and is used by being mounted on a body of a user, the method comprising:

detecting a target of the user in a visual line direction;

detecting a position of the target with respect to a display region of the display unit; and

determining a display position of information based on the position of the target and allowing the display unit to display information.

10. A program which can be executed by a computer controlling a display device that includes a display unit through which outside scenery is transmitted and that displays an image such that the image is visually recognizable together with the outside scenery and is used by being mounted on a body of a user, the program causing the computer to function as:

a target detection unit that detects a target of the user in the visual line direction;

a position detection unit that detects a position of the target with respect to a display region of the display unit; and

an information display control unit that determines a display position of information based on the position of the target detected by the position detection unit and allows the display unit to display the information.
