Abstract

An information processing apparatus accepts an input onto a display screen displayed on a display device. The information processing apparatus determines an input method of a first input using a first time and/or a first trajectory information from a start point to an end point of the accepted first input. The information processing apparatus stores the first trajectory information of the first input in a storage unit for storing therein the trajectory information of an input of which the input method has been determined. The information processing apparatus restores trajectory information of the input that was accepted by accepting, using the first trajectory information stored in the storage unit and trajectory information of a second input if a result of determination with respect to the second input accepted within a predetermined time since the first input is input is different from the input method of the first input.

Claims

1. An information processing apparatus comprising:

an input accepting unit that accepts an input onto a display screen displayed on a display device;

a determining unit that determines an input method of a first input using a first time and/or a first trajectory information from a start point to an end point of the first input accepted by the input accepting unit;

a storage control unit that stores the first trajectory information of the first input of which the input method is determined by the determining unit in a trajectory-information storage unit for storing therein trajectory information of an input of which the input method is determined; and

a restoring unit that restores trajectory information of the input accepted by the input accepting unit using the first trajectory information stored in the trajectory-information storage unit and a second trajectory information of a second input when a result of determination by the determining unit with respect to the second input accepted within a predetermined time since the first input is input is different from the input method of the first input.

2. The information processing apparatus according to claim 1, further comprising:

an undetermined-information storage unit that stores therein undetermined input information indicating input information to be displayed on the display device; and

an input-information generating unit that generates the undetermined input information using the restored trajectory information and stores the generated undetermined input information in the undetermined-information storage unit.

3. The information processing apparatus according to claim 2, further comprising an undetermined-information restoring unit that generates undetermined input information using trajectory information other than the trajectory information previously used for generation of the undetermined input information by the input-information generating unit and restores the generated undetermined input information in the undetermined-information storage unit.

4. The information processing apparatus according to claim 1, further comprising an information deleting unit that deletes trajectory information stored in the trajectory-information storage unit when trajectory information of the input accepted by the input accepting unit is restored by the restoring unit or when a predetermined time has elapsed since the previous input.

5. The information processing apparatus according to claim 1, further comprising an information deleting unit that identifies a positional relationship between multiple pieces of trajectory information stored in the trajectory-information storage unit, and, when the identified positional relationship meets a certain predetermined condition to determine to be inappropriate to a starting stroke of a character, deletes the trajectory information stored in the trajectory-information storage unit.

6. The information processing apparatus according to claim 1, further comprising an information deleting unit that deletes trajectory information stored in the trajectory-information storage unit when the determining unit determines that an input method of an input accepted by the input accepting unit is a handwriting input and also when the number of pieces of trajectory information, which is determined to be a handwriting input and stored in the trajectory-information storage unit, is a predetermined number or more.

7. An input control method that is executed by a computer, the method comprising:

accepting an input onto a display screen displayed on a display device;

determining an input method of a first input using a first time and/or a first trajectory information from a start point to an end point of the accepted first input;

storing the first trajectory information of the first input of which the input method is determined in a trajectory-information storage unit for storing therein trajectory information of an input of which the input method is determined; and

restoring trajectory information of the input that is accepted by accepting, using the first trajectory information stored in the trajectory-information storage unit and a second trajectory information of a second input when a result of determination with respect to the second input accepted within a predetermined time since the first input is input is different from the input method of the first input.

8. A non-transitory computer-readable storage medium having stored therein an input control program causing a computer to execute a process comprising:

accepting an input onto a display screen displayed on a display device;

determining an input method of a first input using a first time and/or a first trajectory information from a start point to an end point of the accepted first input;

storing the first trajectory information of the first input of which the input method is determined in a trajectory-information storage unit for storing therein trajectory information of an input of which the input method is determined; and

restoring trajectory information of the input that was accepted by accepting, using the first trajectory information stored in the trajectory-information storage unit and a second trajectory information of a second input when a result of determination with respect to the second input accepted within a predetermined time since the first input is input is different from the input method of the first input.

9. An information processing apparatus comprising:

a memory that stores therein trajectory information of an input; and

a processor coupled to the memory, wherein the processor executes a process comprising;

accepting an input onto a display screen displayed on a display device;

determining an input method of a first input using a first time and/or a first trajectory information from a start point to an end point of the accepted first input;

storing the first trajectory information of the first input of which the input method is determined in the memory; and

restoring trajectory information of the input that is accepted by accepting, using the first trajectory information stored in the memory and a second trajectory information of a second input when a result of determination with respect to the second input accepted within a predetermined time since the first input is input is different from the input method of the first input.
