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; and

a controller configured to display a virtual keyboard including a plurality of buttons on the touch panel,

wherein the controller is configured to receive input of a character through the virtual keyboard when (i) the touch panel detects a contact to a first button among the plurality of buttons, the first button associated with the character, (ii) the contact slides, on the virtual keyboard, to a second button among the plurality of buttons, and (iii) an angular difference between a direction of entering to the first button and a direction of leaving from the first button is larger than a threshold value, and store information of the received character, and

wherein the controller is further configured, when a predetermined gesture is performed, the predetermined gesture being a gesture in which a user of the information processing device places a finger on any one of four corner regions of the touch panel and moves the finger in a diagonal direction toward a corner region which is opposite to the corner region on which the finger is placed while keeping the finger in contact with the touch panel,

to turn up a part of a displayed first object in the diagonal direction in which the finger moves, and to display a subsequent second object exposed in an area below the part being turned up, and

the controller being configured to, when the finger moves to a predetermined point on the touch panel, display the virtual keyboard in the area below the first object and the subsequent second object, and

when the finger moves into an area of the virtual keyboard from the predetermined point while continuing to maintain contact with the touch panel, the controller is configured to cause the first object to receive input of a character string through the virtual keyboard.

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

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

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

3. The information processing device according to claim 1, 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 information of the received character through the virtual keyboard.

4. The information processing device according to claim 1, wherein the controller is configured to continue the turning up of the first object after displaying the virtual keyboard while the predetermined gesture is continued.

5. The information processing device according to claim 1, wherein when the predetermined gesture is continued and the subsequent second object is displayed full-screen on the touch panel, the controller is configured to set the subsequent second object as a target to be operated.

6. A character input method performed by an information processing device including a touch panel, the character input method comprising:

displaying, by the touch panel, a virtual keyboard including a plurality of buttons;

receiving, by a controller of the information processing device, input of a character through the virtual keyboard when (i) the touch panel detects a contact to a first button among the plurality of buttons, the first button associated with the character, (ii) the contact slides, on the virtual keyboard, to a second button among the plurality of buttons, and (iii) an angular difference between a direction of entering to the first button and a direction of leaving from the first button is larger than a threshold value;

storing, by the controller, information of the received character; and

when a predetermined gesture is performed, the predetermined gesture being a gesture in which a user of the information processing device places a finger on any one of four corner regions of the touch panel and moves the finger in a diagonal direction toward a corner region which is opposite to the corner region on which the finger is placed while keeping the finger in contact with the touch panel,

turning up a part of a displayed first object in the diagonal direction in which the finger moves and

to turn up a part of a displayed first object in the diagonal direction in which the finger moves, and to display a subsequent second object exposed in an area below the part being turned up, and

the controller being configured to, when the finger moves to a predetermined point on the touch panel, display the virtual keyboard in the area below the first object and the subsequent second object, and

when the finger moves into an area of the virtual keyboard from the predetermined point while continuing to maintain contact with the touch panel, the controller is configured to cause the first object to receive input of a character string through the virtual keyboard.

7. The character input method according to claim 6, wherein the turning up the part of the displayed first object is continued after displaying the virtual keyboard while the predetermined gesture is continued.

8. The character input method according to claim 6, further comprising when the predetermined gesture is continued and the subsequent second object is displayed full-screen on the touch panel, setting the subsequent second object as a target to be operated.
