Abstract

An information processing apparatus, includes: a memory, and a processor coupled to the memory and configured to: obtain a gaze position of a user on a display screen, determine whether an object for reading, displayed on the display screen, has been finished reading by the user, based on a threshold and the number of times where movement of the gaze position indicates a newline, the threshold being set in accordance with the number of lines in the object, and change at least one of the threshold and the number of times in response to detection that the movement of the gaze position becomes movement of a certain distance or greater in a second direction different from a first direction of movement indicating a newline.

Claims

1. An information processing apparatus, comprising:

a memory, and

a processor coupled to the memory and configured to;

obtain a gaze position of a user on a display screen,

determine whether an object for reading, displayed on the display screen, has been finished reading by the user, based on a threshold and the number of times where movement of the gaze position indicates a newline, the threshold being set in accordance with the number of lines in the object, and

change at least one of the threshold and the number of times in response to detection that the movement of the gaze position becomes movement of a certain distance or greater in a second direction different from a first direction of movement indicating a newline.

2. The information processing apparatus according to claim 1,

wherein, when detecting that the movement of the gaze position becomes the movement of the certain distance or greater in the second direction, and when detecting movement indicating a newline within a certain time prior to the movement of the gaze position of the certain distance or greater, the processor is configured to change at least one of the threshold and the number of times.

3. The information processing apparatus according to claim 2,

wherein the second direction is the same direction as a direction in which the object is read, and

wherein the certain distance is a value determined in accordance with a threshold in a case of detecting movement indicating a newline.

4. The information processing apparatus according to claim 1,

wherein, when detecting that the movement of the gaze position becomes movement of a certain distance or greater in a direction toward a first line in the object, the processor is configured to:

convert the movement distance of the gaze position in a vertical direction with respect to a direction in which the object is read to the number of lines, and

change at least one of the threshold and the number of times in accordance with the number of lines obtained by the conversion.

5. The information processing apparatus according to claim 1,

wherein, after detecting that first movement of the gaze position becomes movement of a certain distance or greater in a vertical direction with respect to a direction in which the object is read, the processor is configured to:

detect a state in which the movement of the gaze position continues to be in the direction in which the object is read for a certain time or greater, and

determine whether the gaze position upon entering the state is closer to a first line in the object than a position prior to the first movement of the gaze position, and

wherein, when determined that the gaze position upon entering the state is closer to the first line in the object than the position prior to the first movement of the gaze position, the processor is configured to;

convert a distance between the position prior to the first movement of the gaze position and the gaze position in the state, in the vertical direction with respect to the direction in which the object is read, to the number of lines, and

change at least one of the threshold and the number of times in accordance with the number of lines obtained by the conversion.

6. The information processing apparatus according to claim 1,

wherein the object for reading includes text of a line configuration having the lines.

7. An information processing method, comprising:

obtaining a gaze position of a user on a display screen;

determining whether an object for reading, displayed on the display screen, has been finished reading by the user, based on a threshold and the number of times where movement of the gaze position indicates a newline, the threshold being set in accordance with the number of lines in the object; and

changing, by a processor, at least one of the threshold and the number of times in response to detection that the movement of the gaze position becomes movement of a certain distance or greater in a second direction different from a first direction of movement indicating a newline.

8. The information processing method according to claim 7,

wherein, when detecting that the movement of the gaze position becomes the movement of the certain distance or greater in the second direction, and when detecting movement indicating a newline within a certain time prior to the movement of the gaze position of the certain distance or greater, the changing changes at least one of the threshold and the number of times.

9. The information processing method according to claim 8,

wherein the second direction is the same direction as a direction in which the object is read, and

wherein the certain distance is a value determined in accordance with a threshold in a case of detecting movement indicating a newline.

10. The information processing method according to claim 7,

wherein, when detecting that the movement of the gaze position becomes movement of a certain distance or greater in a direction toward a first line in the object, the changing converts the movement distance of the gaze position in a vertical direction with respect to a direction in which the object is read to the number of lines, and the changing changes at least one of the threshold and the number of times in accordance with the number of lines obtained by the conversion.

11. The information processing method according to claim 7,

wherein, after detecting that first movement of the gaze position becomes movement of a certain distance or greater in a vertical direction with respect to a direction in which the object is read, the changing detects a state in which the movement of the gaze position continues to be in the direction in which the object is read for a certain time or greater, and the changing determines whether the gaze position upon entering the state is closer to a first line in the object than a position prior to the first movement of the gaze position, and

wherein, when determined that the gaze position upon entering the state is closer to the first line in the object than the position prior to the first movement of the gaze position, the changing converts a distance between the position prior to the first movement of the gaze position and the gaze position in the state, in the vertical direction with respect to the direction in which the object is read, to the number of lines, and the changing changes at least one of the threshold and the number of times in accordance with the number of lines obtained by the conversion.

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

obtaining a gaze position of a user on a display screen;

determining whether an object for reading, displayed on the display screen, has been finished reading by the user, based on a threshold and the number of times where movement of the gaze position indicates a newline, the threshold being set in accordance with the number of lines in the object; and

changing at least one of the threshold and the number of times in response to detection that the movement of the gaze position becomes movement of a certain distance or greater in a second direction different from a first direction of movement indicating a newline.
