CHARACTER INPUT DEVICE
First Claim
1. A character input device, comprising:
- an input unit provided such that i) first directional input which is selected by directional pressing or tilting one of a plurality of first direction indication locations arranged radially from a reference location and spaced apart from one another, ii) second directional input which is configured to be performed through directional movement from each of the first direction indication locations to one of a plurality of second direction indication locations arranged radially around the first direction indication location, and iii) combined directional input different from the first directional input and the second directional input through combination of the first directional input and the second directional input can be performed respectively;
at least one press detection unit configured to detect the first directional input;
at least one movement detection unit configured to detect the second directional input; and
a control unit configured to extract and display a character code, assigned to each selected one of the direction indication locations, from a memory unit based on results of the detection of the press detection unit and the movement detection unit.

Abstract
A character input device is disclosed. In one embodiment, the character input device includes an input unit, press detection units, movement detection units, and a control unit. The input unit is provided as a single body such that first directional input, which is performed by pressing one of first direction indication locations arranged radially from a reference location and spaced apart from one another, and second directional input, which is performed through movement from each of the first direction indication locations to one of second direction indication locations arranged radially around the first direction indication location, can be performed. The press detection units detect the first directional input. The movement detection units detect the second directional input. The control unit extracts a character code, assigned to each selected one of the direction indication locations, from a memory unit based on results of the detection.

9. A character input device, comprising:
-
an input unit provided such that i) first directional input which is configured to be performed through selection of one from among a plurality of first direction indication locations arranged radially on the input unit itself and spaced apart from one another, ii) second directional input which is configured to be performed through movement from each of the first direction indication locations to one of second direction indication locations arranged circumferentially around the first direction indication location, and iii) third directional input which is configured to be performed through entire movement from a reference location to one of third direction indication locations arranged radially from the reference location and spaced apart from one another can be performed respectively; at least one movement detection unit configured to detect the second directional input and the third directional input of the input unit; at least one press detection unit configured to detect the first directional input; and a control unit configured to extract and display a character code, assigned to each selected direction indication location, from a memory unit based on results of the detection of the movement detection unit and the press detection unit. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
