Abstract

A head-mount type display device includes an image display device adapted to allow a user to visually recognize an image in a state of being mounted on a head of a user, a detection section disposed in the image display device and adapted to detect biological information of the user, a control section adapted to perform control of the image visually recognized by the user using the image display device, and an annunciation section adapted to inform the user of image control information as information related to the control of the image based on a variation in the biological information detected.

Claims

1. A head-mount type display device comprising:

an image display device adapted to allow a user to visually recognize an image in a state of being mounted on a head of a user;

a detection section adapted to detect biological information of the user, and then transmit the biological information to the image display device;

a control section adapted to perform control of the image visually recognized by the user using the image display device; and

an annunciation section adapted to inform the user of image control information as information related to the control of the image based on a variation in the biological information detected.

2. The head-mount type display device according to claim 1, wherein

the detection section is disposed so as to have contact with the user, and keep the contact with the user.

3. The head-mount type display device according to claim 1, wherein

the biological information is information for identifying a pulse wave.

4. The head-mount type display device according to claim 3, wherein

the annunciation section informs the user of the image control information based on a variation in heartbeat fluctuation due to the pulse wave.

5. The head-mount type display device according to claim 1, wherein

the biological information is information for identifying an open-close state of an eye.

6. The head-mount type display device according to claim 1, wherein

the biological information is information for identifying a state of a pupil.

7. The head-mount type display device according to claim 1, wherein

the biological information is information for identifying redness of an eye.

8. The head-mount type display device according to claim 1, wherein

the biological information is information for identifying at least one of a state of an external ocular muscle and a state of an internal ocular muscle.

9. The head-mount type display device according to claim 1, wherein

the biological information is information for identifying a body temperature.

10. The head-mount type display device according to claim 1, wherein

the biological information is information for identifying perspiration.

11. The head-mount type display device according to claim 1, wherein

the annunciation section makes the control section perform control of making the user visually recognize the image control information as an image using the image display device.

12. The head-mount type display device according to claim 1, wherein

the annunciation section outputs the image control information as a sound to make the user recognize the image control information.

13. The head-mount type display device according to claim 1, wherein

the control of the image is control of changing the image so as not to be visually recognized by the user.

14. A method of controlling a head-mount type display device including an image display device adapted to allow a user to visually recognize an image in a state of being mounted on a head of a user, a control section adapted to perform control of the image visually recognized by the user using the image display device, and a detection section adapted to detect biological information of the user, and then transmit the biological information to the image display device, the method includes

making the detection section detect the biological information;

and

informing the user of image control information as information related to the control of the image based on a variation in the biological information detected.
