Data input device
First Claim
1. A data input device comprising:
- a base;
an input unit positioned at the base to allow each of first direction input and second direction input to be independently performed in a state where one finger is placed on the upper of the input unit, the first direction input being performed by moving the input unit from a reference position to any one of a plurality of first direction indication positions spaced and arranged radially from the reference position within a predetermined input area and the second direction input being performed by selecting any one of a plurality of second direction indication positions spaced and arranged radially in the input unit;
a first sensing unit configured to sense the first direction input;
a second sensing unit configured to sense the second direction input; and
a control unit configured to extract and run a first data or a second data from a memory unit, the first data being assigned to the first direction indication position in which the movement of the input unit is sensed, and the second data being assigned to the second direction indication position in which the second direction input is sensed, wherein any one of the first direction input and the second direction input is configured to perform the input unit toward any direction of a plurality of the directions in a state where the other is performed, so that a first data assigned to the first direction input and a second data assigned to the second direction input can be simultaneously input.

Abstract
A character input device and its method are disclosed. In one embodiment, the device includes: i) a base, ii) an input unit positioned at the base to allow each of first direction input and second direction input to be independently performed, the first direction input being performed by moving the input unit from a reference position to any one of a plurality of first direction indication positions spaced and arranged radially from the reference position within a predetermined input area and the second direction input being performed by selecting any one of a plurality of second direction indication positions spaced and arranged radially in the input unit itself; a first sensing unit for sensing the movement of the input unit, iii) a second sensing unit for sensing the second direction input and iv) a control unit for extracting and running a first character or a second character from a memory unit, the first character being assigned to the first direction indication position in which the movement of the input unit is sensed, and the second character being assigned to the second direction indication position in which the second direction input is sensed, thereby making it possible to minimize a necessary space for inputting characters and accurately input each character according to a user'"'"'s intention.
