Abstract

Provided is an information processing apparatus including a processing unit configured to perform a derivation process of deriving a relative positional relation between a user and a display screen such that a calibration position is within an angle of view of the display screen, the calibration position being stared by the user of a line of sight detection target when sampling data for calibration of a line of sight is acquired.

Claims

1. An information processing apparatus comprising

a processing unit configured to perform a derivation process of deriving a relative positional relation between a user and a display screen such that a calibration position is within an angle of view of the display screen, the calibration position being stared by the user of a line of sight detection target when sampling data for calibration of a line of sight is acquired.

2. The information processing apparatus according to claim 1, wherein the processing unit sets an intersection point of a reference vector corresponding to a forward direction of a face of the user and a plane including the display screen, as the calibration position, and

in a case in which the calibration position is not within the angle of view of the display screen, the processing unit derives the relative positional relation such that the calibration position falls within the angle of view of the display screen.

3. The information processing apparatus according to claim 2, wherein, in a case in which the calibration position is within the angle of view of the display screen, the processing unit causes an object indicating the calibration position to be displayed within the angle of view of the display screen.

4. The information processing apparatus according to claim 2, wherein the processing unit specifies the plane on a basis of a predetermined object which is displayed on the display screen and detected from a captured image obtained by imaging in the forward direction from the face of the user.

5. The information processing apparatus according to claim 2, wherein the processing unit derives the relative positional relation by causing a derivation object for deriving the relative positional relation to be displayed on the display screen.

6. The information processing apparatus according to claim 5, wherein the derivation object is an object indicating a direction in which the user moves or a direction in which the display screen is moved.

7. The information processing apparatus according to claim 6, wherein the derivation object is displayed in an animated manner.

8. The information processing apparatus according to claim 1, wherein the processing unit derives the relative positional relation by causing a voice for deriving the relative positional relation to be output from an audio output device.

9. The information processing apparatus according to claim 1, wherein the processing unit causes a notification indicating a derived state to be given to the user.

10. The information processing apparatus according to claim 1, wherein the processing unit performs the derivation process in a case in which a set start condition is determined to be satisfied.

11. The information processing apparatus according to claim 1, wherein the processing unit further performs a calibration process of calibrating a detection result of the line of sight on a basis of calibration information based on the acquired sampling data.

12. The information processing apparatus according to claim 11, wherein the processing unit

generates the calibration information on a basis of the sampling data, and

calibrates the detection result of the line of sight on a basis of the generated calibration information.

13. An information processing method executed by an information processing apparatus, the method comprising

a step of deriving a relative positional relation between a user and a display screen such that a calibration position is within an angle of view of the display screen, the calibration position being stared by the user of a line of sight detection target when sampling data for calibration of a line of sight is acquired.

14. A computer readable storage medium having a program stored therein, the program causing a computer to implement a function of deriving a relative positional relation between a user and a display screen such that a calibration position is within an angle of view of the display screen, the calibration position being stared by the user of a line of sight detection target when sampling data for calibration of a line of sight is acquired.
