Abstract
An input device is provided. The input device includes a display that displays a keypad for input of a character and a character input window showing a character string input through the keypad; a gesture sensor that senses a gesture of a user; and a controller that controls the display, based on the gesture, wherein the keypad comprises: a central item; a plurality of peripheral items arranged while being spaced from one another around the central item; and a plurality of guide lines corresponding to the plurality of the peripheral items, the plurality of the guide lines are in a straight or curved line form directed from each of the plurality of the peripheral items toward the central item, and have different forms and directions.
Claims16
An input device for providing a character input interface, comprising:
- a display that displays a keypad for input of a character, and a character input window showing a character string input through the keypad;
- a gesture sensor that senses a gesture of a user;
- and
- a controller that controls the display, based on the gesture, wherein the keypad comprises:
- a central item;
- a plurality of peripheral items arranged while being spaced from one another around the central item;
- and
- a plurality of guide lines corresponding to the plurality of the peripheral items, the plurality of the guide lines are in a straight or curved line form directed from each of the plurality of the peripheral items toward the central item, and have different forms and directions, and wherein when a character selection gesture for selecting any one item of the keypad is input through the gesture sensor, the display inserts an individual character allocated to the item selected by the character selection gesture into a character string of the character input window.
A method for inputting a character by using an input device for providing a character input interface, comprising:
- displaying a keypad for inputting a character into a character input window showing an input character string;
- sensing a character selection gesture for selecting any one item of the keypad;
- and
- inserting an individual character allocated to an item selected by the character selection gesture into a character string of the character input window, wherein the keypad comprises:
- a central item, a plurality of peripheral items arranged while being spaced from one another around the central item;
- and
- a plurality of guide lines corresponding to the plurality of the peripheral items, and the plurality of the guide lines are in a straight or curved line form directed from each of the plurality of the peripheral items toward the central item, and have different forms and directions.
A device for inputting a character, comprising:
- a gesture sensor that senses a user's gesture corresponding to a keypad of a character input interface displayed in a display device;
- and
- a controller that generates a control signal for controlling the display device based on the gesture to transmit the control signal to the display device, wherein the keypad comprises a central item and a plurality of peripheral items arranged while being spaced from one another around the central item, the central item is displayed at a position overlapping with a cursor displayed in a character input window of the character input interface, and when a character selection gesture for selecting any one of the central item and the plurality of the peripheral items is input, the controller generates a control signal corresponding to the selected item.
