  • Publication number: 20120212411
    Abstract: A character input device includes an input unit for enabling direction movement input and direction pressing input; a movement input detector for detecting the direction movement input; a pressing input detector for detecting the direction pressing input; and a controller for extracting characters from a memory for execution, the characters corresponding to a result of detection performed by the movement input detector and the pressing input detector. The character input device enables its user to input desired characters accurately while minimizing the space necessary for character input. In addition, direction movement input and direction pressing input can be combined to input at least two phonemes through a single continuous operation, for rapid character input. Furthermore, the minimized input space requirement facilitates compactness and slimness of the product.

  • Publication number: 20110001718
    Abstract: There is provided a data input device. The data input device comprises a plurality of sensing units having sensors, a plurality of direction indicating positions and direction inputs in an input radius spaced and arranged from a center position in a radial direction in a uniform range in one input unit, and a controller so that data are input by continuously performing at least two direction inputs. Therefore, the input unit of a portable electronic apparatus having a narrow input space sequentially performs a plurality of movement combinations in accordance with the movements corresponding to first to sixth direction inputs from a reference position in a radial direction to minimize an input space and to rapidly and correctly input desired characters by a series of input operations.
