Problems solved by technology

[0010] However, this type of input device has a problem in that it is not a type of input device suitable for application to personal portable information because it must be carried and because input can only be performed in a state where these types of input devices are placed on a supporting surface. terminal, thus causing inconvenience in which the personal portable information terminal requires input in a state where the personal portable information terminal is held in hand and moved at the same time

Embodiment Construction

[0088] Hereinafter, a first embodiment of a character input device according to the present invention will be described in detail with reference to the accompanying drawings.

[0089] refer to figure 1 , in the character input device according to the present invention, the input unit 1 includes four input keys 10 respectively arranged in four radial directions from the center of the device so that the distance between adjacent input keys 10 is uniform. The respective input keys 10 are provided to indicate positions M1, M2, M3 and M4 to a plurality of directions arranged radially around the reference position (see Image 6 ) is movable, and each input key 10 is provided to be able to perform a directional movement input M for inputting a character assigned to each direction indicating position M1, M2, M3, and M4.

[0090] Here, a movement detection unit 61 may be further included (see figure 2 ) and the control unit 40, wherein the movement detection unit 61 is used to detec...

Abstract

Disclosed herein is a character input device including a plurality of directional input keys. The character input device includes input means including four input keys that are arranged in four radial directions around a center so that distances between adjacent input keys are uniform. The respective input keys are provided such that they can be moved toward a plurality of direction indication locations arranged in radial directions around a reference location, and can perform di not rectional movement input. Accordingly, each of characters, numbers, and symbols can be input through a single action using four input keys, thereby enabling the minimization of the space and rapid and accurate character input. Furthermore, characters arranged on respective input keys are separately arranged in the directions of the movement of input keys, and thus a user can easily become accustomed to the operation of the input keys, thereby enabling efficient character input.

Description

technical field [0001] The present invention relates generally to character input devices, and particularly to a character input device capable of inputting each of characters, numerals, and symbols by a single action using a minimum number of input keys, thereby improving efficiency of character input. Background technique [0002] With the development of software and semiconductor technology and data processing technology, information devices are gradually becoming smaller, and the amount and importance of character input using such information devices are gradually increasing. [0003] Meanwhile, inputting various characters or commands to such information devices presents many problems. For example, an input device such as a keypad used in a personal computer (PC) or a notebook computer makes it difficult to realize a small information device because there is a limit to reducing the size of the input device, and a touch screen scheme used in a personal data assistant (PD...
