Abstract

According to an aspect, an information processing device includes: a touch panel for detecting a contact; and a controller configured to display a virtual keyboard including a plurality of buttons on the touch panel, and receive, when the touch panel detects a contact started at a first position on the surface of the touch panel and terminated at a second position on the surface of the touch panel, a character string including characters corresponding to the buttons displayed on a trajectory obtained by connecting each position at which the contact is detected from when the contact is started at the first position to when the contact is terminated at the second position as input.

Claims

1. An information processing device comprising:

a touch panel for detecting a contact; and

a controller configured to

display a virtual keyboard including a plurality of buttons on the touch panel, and

receive, when the touch panel detects a contact started at a first position on the surface of the touch panel and terminated at a second position on the surface of the touch panel, a character string including characters corresponding to the buttons displayed on a trajectory obtained by connecting each position at which the contact is detected from when the contact is started at the first position to when the contact is terminated at the second position as input.

2. The information processing device according to claim 1, wherein

the controller is configured to receive the character string including a character corresponding to a button displayed at a position where a predetermined gesture is performed among the characters corresponding to the buttons displayed on the trajectory as input.

3. The information processing device according to claim 2, wherein

the controller is configured to receive the character string including a character corresponding to a button displayed at the first position among the characters corresponding to the buttons displayed on the trajectory as input.

4. The information processing device according to claim 2, wherein

the controller is configured to receive the character string including a character corresponding to a button displayed at the second position among the characters corresponding to the buttons displayed on the trajectory as input.

5. The information processing device according to claim 2, wherein

the controller is configured to receive the character string including a character corresponding to a button displayed at a position where change in a movement direction is performed among the characters corresponding to the buttons displayed on the trajectory as input.

6. The information processing device according to claim 2, wherein

the controller is configured to receive the character string including a character corresponding to a button displayed at a position where movement to draw a trajectory in a predetermined shape is performed among the characters corresponding to the buttons displayed on the trajectory as input.

7. The information processing device according to claim 2, wherein

when the character string obtained by combining the characters corresponding to the buttons displayed at the positions where the predetermined gestures are performed is not a proper character string,

the controller is configured to receive the character string supplied with a character corresponding to a button displayed at a position other than the positions where the predetermined gestures are performed among the characters corresponding to the buttons displayed on the trajectory as input.

8. The information processing device according to claim 2, wherein

the controller is configured to

perform matching between the character string obtained by combining the characters corresponding to the buttons displayed at the positions where the predetermined gestures are performed and a dictionary, and

receive, when a character string that matches the combined character string is retrieved, the character string thus retrieved as input.

9. The information processing device according to claim 1, wherein

the controller is configured to

receive input of attribute information through the virtual keyboard when the touch panel detects a contact started in a display area of an object displayed on the touch panel and maintained to a display area of the virtual keyboard, and

store the attribute information thus received in a manner associated with the object displayed at a position where the contact is started.

10. The information processing device according to claim 9, wherein

the controller is configured to display the virtual keyboard on the touch panel when start of the contact in the display area of the object is detected by the touch panel.

11. The information processing device according to claim 9, wherein

when a predetermined gesture is performed subsequently to start of the contact in the display area of the object,

the controller is configured to change an object to be displayed on the touch panel in accordance with a predetermined display order.

12. The information processing device according to claim 9, wherein

when the contact is detected while a plurality of objects displayed on the touch panel are in a selected state,

the controller is configured to store the attribute information received through the virtual keyboard in a manner associated with the objects.

13. A character input method performed by an information processing device including a touch panel that detects a contact, the character input method comprising:

displaying a plurality of buttons on the touch panel;

detecting, by the touch panel, a contact started at a first position on the surface of the touch panel and terminated at a second position on the surface of the touch panel; and

receiving a character string including characters corresponding to the buttons displayed on a trajectory obtained by connecting each position at which the contact is detected by the touch panel from when the contact is started at the first position to when the contact is terminated at the second position as input.

14. The character input method according to the claim 13, further comprising:

displaying an object on the touch panel; and

storing the character string received as input as attribute information of the object when the contact is started at the first position in a display area of the object.
