Abstract

A video image display system including an information apparatus and a transmissive head mounted display that allows a user to visually recognize video images distributed from the information apparatus as virtual images is provided. The information apparatus includes a video image distributor that distributes video images corresponding to a specific geographic region to the head mounted display. The head mounted display includes a motion detector that detects motion of the user'"'"'s head and allows the user to visually recognize, as virtual images, video images selected based on motion information representing the motion.

Claims

1. A video image display system comprising:

an information apparatus; and

a transmissive head mounted display that allows a user to visually recognize video images distributed from the information apparatus as virtual images,

wherein the information apparatus includes a video image distributor that distributes video images corresponding to a specific geographic region to the head mounted display, and

the head mounted display includes a motion detector that detects motion of the user'"'"'s head and allows the user to visually recognize, as virtual images, the video images selected based on motion information representing the motion.

2. The video image display system according to claim 1,

wherein the head mounted display includes an information transmitter that transmits the motion information to the information apparatus,

the information apparatus includes an information receiver that receives the motion information from the head mounted display located in the specific geographic region, and

the video image distributor selects at least one of the multiple sets of video images corresponding to the specific geographic region based on the motion information and distributes the selected video images to the head mounted display from which the motion information has been transmitted.

3. The video image display system according to claim 2,

wherein the multiple sets of video images include replayed video images generated by capturing images of an object in the specific geographic region in a predetermined period, and

when the motion of the user'"'"'s head represented by the motion information is greater than or equal to a threshold set in advance, the video image distributor selects the replayed video images corresponding to a period determined based on the motion information.

4. The video image display system according to claim 3,

wherein the replayed video images are visually recognized in a position closer to the center of the field of view of the user of the head mounted display than the other video images.

5. The video image display system according to claim 3,

wherein the replayed video images are displayed in the field of view of the user of the head mounted display in at least one of the manners that the replayed video images are enlarged, the replayed video images are enhanced, and the replayed video images are provided with a predetermined mark, as compared with the other video images.

6. The video image display system according to claim 2,

wherein the video image distributor stops distributing video images for a predetermined period to the head mounted display from which the motion information has been transmitted when the motion of the user'"'"'s head represented by the motion information is greater than a threshold set in advance.

7. The video image display system according to claim 2,

wherein the multiple sets of video images are generated by capturing images of an object in the specific geographic region,

the head mounted display further includes a position detector that detects a current position,

the information transmitter transmits positional information representing the current position to the information apparatus, and

the video image distributor selects video images based on the motion information and the positional information.

8. The video image display system according to claim 7,

wherein the video image distributor selects video images generated by capturing images of an object at an angle different from the angle of a line of sight of the user of the head mounted display estimated based on the motion information and the positional information by at least a predetermined value.

9. The video image display system according to claim 7,

wherein the video image distributor selects video images generated by capturing images of an object located outside a predetermined area in a field of view of the user of the head mounted display estimated based on the motion information and the positional information.

10. The video image display system according to claim 1,

wherein the head mounted display in the specific geographic region includes

a video image receiver that receives the multiple sets of video images corresponding to the specific geographic region from the information apparatus, and

a video image selector that selects video images to be visually recognized by the user from the multiple sets of video images based on the motion information.

11. A transmissive head mounted display to which an information apparatus distributes video images corresponding to a specific geographic region and which allows a user to visually recognize the distributed video images as virtual images, the head mounted display comprising a motion detector that detects motion of the user'"'"'s head and allows the user to visually recognize, as virtual images, the video images selected based on motion information representing the motion.

12. A video image display system comprising:

an information apparatus; and

a transmissive head mounted display that allows a user to visually recognize video images distributed from the information apparatus as virtual images,

wherein the head mounted display includes

a position detector that detects a current position, and

an information transmitter that transmits positional information representing the current position to the information apparatus, and

the information apparatus includes

an information receiver that receives the positional information from the head mounted display located in a specific geographic region, and

a video image distributor that selects at least one of multiple sets of video images corresponding to the specific geographic region based on the positional information and distributes the selected video images to the head mounted display from which the positional information has been transmitted.
