Abstract

An information processing apparatus includes: a memory, and a processor coupled to the memory and configured to: calculate a first distance between an end of a first line in an object for reading displayed on a display screen and a beginning of a second line that is next to the first line in the object, and set, in accordance with the first distance, a condition for determining whether the object has been finished reading by a user based on detecting movement of a gaze position of the user on the display screen.

Claims

1. An information processing apparatus, comprising:

a memory, and

a processor coupled to the memory and configured to;

calculate a first distance between an end of a first line in an object for reading displayed on a display screen and a beginning of a second line that is next to the first line in the object, and

set, in accordance with the first distance, a condition for determining whether the object has been finished reading by a user based on detecting movement of a gaze position of the user on the display screen.

2. The information processing apparatus according to claim 1,

wherein, when the first distance exceeds a first threshold that is set in accordance with a range that is readable without moving the gaze position, the processor is configured to increase a second threshold used in counting the number of times where movement of the gaze position indicates a newline.

3. The information processing apparatus according to claim 1,

wherein, when the first distance exceeds a first threshold that is set in accordance with a range that is readable without moving the gaze position, the processor is configured to set a second distance in accordance with the first distance to a reference value used in comparison for determining whether movement of the gaze position indicates a line break.

4. The information processing apparatus according to claim 2,

wherein, the processor is configured to:

obtain the gaze position on the display screen,

count the number of times where a third distance of movement of the gaze position in a direction opposite to a direction in which the text is read exceeds the first threshold, and,

when the counted number of times becomes greater than or equal to the second threshold, store data representing that the object has been finished reading in a data storage.

5. The information processing apparatus according to claim 3,

wherein, the processor is configured to:

obtain the gaze position on the display screen,

determine whether a third distance of movement of the gaze position in a direction opposite to a direction in which the text is read matches the reference value, and,

when determined that the third distance matches the reference value, store data representing that the first line has been finished reading in a data storage.

6. The information processing apparatus according to claim 1,

wherein the object for reading includes text of a line configuration having the first line and the second line.

7. An information processing method, comprising:

calculating a first distance between an end of a first line in an object for reading displayed on a display screen and a beginning of a second line that is next to the first line in the object; and

setting, by a processor, in accordance with the first distance, a condition for determining whether the object has been finished reading by a user based on detecting movement of a gaze position of the user on the display screen.

8. The information processing method according to claim 7,

wherein, when the first distance exceeds a first threshold that is set in accordance with a range that is readable without moving the gaze position, the setting increases a second threshold used in counting the number of times where movement of the gaze position indicates a newline.

9. The information processing method according to claim 7,

wherein, when the first distance exceeds a first threshold that is set in accordance with a range that is readable without moving the gaze position, the setting sets a second distance in accordance with the first distance to a reference value used in comparison for determining whether movement of the gaze position indicates a line break.

10. The information processing method according to claim 8, further comprising:

obtaining the gaze position on the display screen;

counting the number of times where a third distance of movement of the gaze position in a direction opposite to a direction in which the text is read exceeds the first threshold; and

,

when the counted number of times becomes greater than or equal to the second threshold, storing data representing that the object has been finished reading in a data storage.

11. The information processing method according to claim 9, further comprising:

obtaining the gaze position on the display screen;

determining whether a third distance of movement of the gaze position in a direction opposite to a direction in which the text is read matches the reference value; and

,

when determined that the third distance matches the reference value, storing data representing that the first line has been finished reading in a data storage.

12. A computer-readable recording medium storing a program that causes a computer to execute a procedure, the procedure comprising:

calculating a distance between an end of a first line in an object for reading displayed on a display screen and a beginning of a second line that is next to the first line in the object; and

setting, in accordance with the calculated distance, a condition for determining whether the object has been finished reading by a user based on detecting movement of a gaze position of the user on the display screen.
