Information processing apparatus and information processing method

1. An information processing apparatus, comprising:

a storage unit;

an acquiring unit configured to acquire first information indicating a first user operation; and

a display control unit configured to:

set a first threshold value based on an accuracy of detection of a first position of a gazing point of a user;

control a display position of an indicator on a display device based on a gaze input and a difference between a first position of the indicator and the first position of the gazing point of the user, wherein

the difference exceeds the set first threshold value, and

the first position of the indicator is based on the first user operation;

change the display position of the indicator from the first position of the indicator to a second position of the indicator based on the control, wherein the second position of the indicator corresponds to the first position of the gazing point of the user;

control the storage unit to store the first position of the gazing point of the user and the second position of the indicator; and

control the display position of the indicator to return to the stored second position of the indicator based on a displacement of the gazing point of the user from the stored first position of the gazing point to a second position of the gazing point within a specific time period.

2. The information processing apparatus according to claim 1 , wherein the display control unit is further configured to set the first threshold value based on content displayed on the display device.

3. The information processing apparatus according to claim 1 , wherein the display control unit is further configured to set a fixed value as the first threshold value.

4. The information processing apparatus according to claim 1 , wherein

the acquiring unit is further configured to acquire second information indicating a plurality of user operations, and

the display control unit is further configured to:

select a second user operation of the plurality of user operations based on a priority set for each of the plurality of user operations; and

control the display position of the indicator on the display device based on the second user operation.

5. The information processing apparatus according to claim 4 , wherein the display control unit is further configured to control the display position of the indicator using the gaze input, based on a priority of the gaze input that is higher than the priority of the second user operation.

6. The information processing apparatus according to claim 4 , wherein

the display control unit is further configured to control the display position of the indicator using the gaze input, based on third information indicating a third user operation of the plurality of user operations,

the third user operation corresponds to a movement of the indicator, and

a priority of the gaze input is higher than the priority of the third user operation.

7. The information processing apparatus according to claim 1 , wherein the display control unit is further configured to control the display device to display the indicator at the second position of the indicator corresponding to the first position of the gazing point.

8. An information processing method, comprising:

acquiring information indicating a user operation;

setting a threshold value based on an accuracy of detection of a first position of a gazing point of a user;

controlling a display position of an indicator on a display device based on a gaze input and a difference between a first position of the indicator and the first position of the gazing point of the user, wherein

the difference exceeds the set threshold value, and

the first position of the indicator is based on the user operation;

changing the display position of the indicator from the first position of the indicator to a second position of the indicator based on the control, wherein the second position of the indicator corresponds to the first position of the gazing point of the user;

controlling a storage unit to store the first position of the gazing point of the user and the second position of the indicator; and

controlling the display position of the indicator to return to the stored second position of the indicator based on a displacement of the gazing point of the user from the stored first position of the gazing point to a second position of the gazing point within a specific time period.

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

acquiring, by an acquiring unit of the information processing apparatus, information indicating a user operation;

setting, by a display control unit of the information processing apparatus, a threshold value based on an accuracy of detection of a first position of a gazing point of a user;

controlling, by the display control unit, a display position of an indicator on a display device based on a gaze input and a difference between a first position of the indicator and the first position of the gazing point of the user, wherein

the difference exceeds the set threshold value, and

the first position of the indicator is based on the user operation;

changing, by the display control unit, the display position of the indicator from the first position of the indicator to a second position of the indicator based on the control, wherein the second position of the indicator corresponds to the first position of the gazing point of the user;

controlling, by the display control unit, a storage unit of the information processing apparatus to store the first position of the gazing point of the user and the second position of the indicator; and

controlling, by the display control unit, the display position of the indicator to return to the stored second position of the indicator based on a displacement of the gazing point of the user from the stored first position of the gazing point to a second position of the gazing point within a specific time period.

10. The information processing apparatus according to claim 1 , wherein the display control unit is further configured to:

set the first threshold value based on a distance between a position of an eye of the user and the first position of the gazing point; and

disable the gaze input based on a speed of a movement of a line of sight of the user that is below a second threshold value.
