Information processing apparatus, information processing method, and program

1. An information processing apparatus, comprising:

an eyeball position estimation unit configured to estimate an eyeball position of a user in a pupil-corneal reflection method on the basis of a captured image including an eye of the user captured when the eye of the user looking at a display surface is irradiated with light;

a discrepancy estimation unit configured to estimate an amount of discrepancy between a line-of-sight position on the display surface and a visual field center of the display surface, the line-of-sight position being identified on the basis of the eyeball position; and

an operation instruction unit configured to issue an operation instruction to adjust a position of a device including the display surface on the basis of the estimated amount of discrepancy.

2. The information processing apparatus according to claim 1 ,

wherein the operation instruction unit displays, on the display surface, an operation instruction object that instructs the user to move the device in a direction in which the amount of discrepancy between the eyeball position on the display surface and the visual field center of the display surface is resolved.

3. The information processing apparatus according to claim 2 ,

wherein the operation instruction unit displays, on the display surface, a target object indicating the visual field center of the display surface, and an object indicating the eyeball position on the display surface.

4. The information processing apparatus according to claim 1 ,

wherein the operation instruction unit uses an operation instruction object to notify the user of a method of operating the device to resolve the amount of discrepancy between the eyeball position on the display surface and the visual field center of the display surface.

5. The information processing apparatus according to claim 2 ,

wherein the operation instruction unit hides the operation instruction object displayed on the display surface when the amount of discrepancy between the eyeball position on the display surface and the visual field center of the display surface is less than or equal to a predetermined value.

6. The information processing apparatus according to claim 1 ,

wherein the device is an imaging apparatus to which an electronic view finder is connected.

7. The information processing apparatus according to claim 1 ,

wherein the device is a glasses-type wearable terminal that covers at least fronts of eyes of the user.

8. An information processing method, comprising:

in an information processing apparatus:

estimating an eyeball position of a user in a pupil-corneal reflection method on the basis of a captured image including an eye of the user captured when the eye of the user looking at a display surface is irradiated with light;

estimating an amount of discrepancy between an eyeball position on the display surface and a visual field center of the display surface, the eyeball position being identified on the basis of the eyeball position; and

issuing an operation instruction to adjust a position of a device including the display surface on the basis of the estimated amount of discrepancy.

9. A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:

estimating an eyeball position of a user in a pupil-corneal reflection method on the basis of a captured image including an eye of the user captured when the eye of the user looking at a display surface is irradiated with light;

estimating an amount of discrepancy between an eyeball position on the display surface and a visual field center of the display surface, the eyeball position being identified on the basis of the eyeball position; and

issuing an operation instruction to adjust a position of a device including the display surface on the basis of the estimated amount of discrepancy.
