The present invention relates to a character input method and apparatus, and more particularly, to a character input method and a character input apparatus capable of inputting characters such as numbers, alphabets, and Korean characters based on a touch pad method.

Recently, instead of providing a key button as an input device in a mobile terminal such as a mobile phone, a PDA, a PMP, a UMPC, products that display a virtual keypad or a keypad screen on a touch screen have gained popularity. When the virtual keypad or keypad screen is displayed on the display, a key corresponding to the point may be input by touching the finger on the display using a finger or a stylus pen.

This virtual keypad method is applied to the number keys of 12-15 keys provided in the mobile phone, using the keys in the numeric mode, you can enter a number from 0 to 9, in the Hangul mode One or two consonants or vowels are assigned to one key, and three to four alphabets are assigned to one key in the English alphabet mode, so that the input characters change according to the number of key presses. For example, if "A, B, C" is assigned to the number 2 key, A is pressed once and A is pressed twice, while B is pressed twice in succession. In recent years, a QWERTY keyboard keyboard having more than 30 keys provided in general computers and laptops has also been implemented in a virtual keypad method.

However, if you implement a virtual keypad with 12-15 keys by assigning 3-4 characters to one key as described above, there are many times (1-3 times or more) to touch to enter one character. However, there is a problem that the input speed is very low. In addition, when a dozens of keys (e.g., a QWERTY keyboard) are implemented as a virtual keypad, the display of the mobile terminal is very narrow, so that one key is very small in the displayed area, so that the user may not have the desired key. By touching the key, a typo frequently occurred.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a character input method and apparatus capable of quickly and accurately inputting characters based on a touch pad of a non-contact type.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

1 is a view showing a character input device according to an embodiment of the present invention. Referring to the drawings, the character input apparatus 100 according to the exemplary embodiment of the present invention includes an input unit 110, a memory 120, a controller 130, and an output unit 140.

The input unit 110 is configured to sense the approach and contact of an external object or a human body, but may be a non-contact touch screen method, but the present invention is not limited thereto. Here, the non-contact touch screen method is a method in which the position of the access point can be detected by only approaching within a predetermined distance without actually touching the touch pad. The principle will be briefly described as follows. 2 is a diagram illustrating a distance between an input unit and a finger. 2, the straight line distance D or the shortest distance D between the surface of the input unit 110 and the finger 200 is displayed. 3 is a diagram illustrating a signal before a finger approaches, FIG. 4 is a diagram illustrating a signal when the finger approaches within a predetermined distance, and FIG. 5 is a diagram illustrating a signal when the finger contacts. Referring to FIG. 3, it can be seen that there is no change in the average value of the signal when the finger approaches within a predetermined distance (D >> a). Meanwhile, referring to FIG. 4, when the finger approaches within a predetermined distance (0 <D <a), it can be seen that the average value of the signal has increased. Referring to FIG. 5, when the finger touches the surface of the input unit 110 (D ˜ 0), the average value of the signal is much higher than when the finger approaches within a predetermined distance. As such, even if a finger or a stylus pen approaches within a predetermined distance, a change in a signal is generated, thereby implementing a non-contact touch screen method capable of detecting both access and contact.

Referring back to FIG. 1, the memory 120 is a storage device that stores basic keypad screen information, keypad screen information corresponding to a current access point or a contact point, and current character information corresponding to each touch point.

If an access is detected, the controller 130 displays a keypad screen if the touch corresponds to an access point, and if a touch is detected, the controller 130 inputs a key corresponding to the current touch point. For example, when it is detected that a finger or a stylus pen or the like is approached, the controller 130 displays information on the keypad screen (ie, an enlarged window) corresponding to the current access point (x 0 , y 0 ) in the memory 120. The screen (enlarged window) is read and output to the output unit 140. The enlarged window is preferably not changed while the access state is maintained, but the present invention is not limited thereto. A detailed description of the process performed by the controller 130 will be described later with reference to FIGS. 6 to 11. The output unit 140 is an output device for outputting a basic keypad screen and a keypad screen corresponding to the current access point.

6 is a view showing a sequence of a character input method according to an embodiment of the present invention. Referring to FIG. 6, first, a basic keypad screen is output before a finger or a stylus pen approaches (S110). 7 is an example of a basic keypad screen displayed before a finger approaches. Referring to FIG. 7, when the distance D between the finger 200 and the input unit 110 is greater than or equal to a predetermined distance (that is, before approaching), the output unit displays a basic keypad screen. The basic keypad screen may include two or more keys (eg, 'A', 'B', and 'C') displayed as one button image ABC.

If there is an access of an external object (eg, a stylus pen) or a body (eg, a finger) (“YES” in step S120), a keypad screen corresponding to the access point is displayed (step S130). For example, an image in which characters corresponding to an access point are enlarged may be displayed on a basic keypad screen. 8 is an example of a screen displayed when a finger approaches within a predetermined distance. Referring to FIG. 8, since the key corresponding to the access point is "D / E / F", the characters included in the key are separated and enlarged and displayed on the enlarged window W. FIG. Specifically, in the enlarged window W, the first letter D is displayed at its original position, the second letter E is at the left of the original position, and the third letter F is at the top of the original position. However, it may be displayed on the right side or the bottom of the original position, or may be displayed at the position in the diagonal direction, the present invention is not limited thereto. On the other hand, the magnification of the magnification of the magnification window W may be proportional to the approach duration.

Then, in the state in which the screen of step S130 is displayed, if a contact of an external object or body occurs (YES in step S140), a key corresponding to the current contact point is input (step S150). Here, the key corresponding to the current contact point is determined based on the keypad screen displayed at the moment of contact, wherein the screen displayed at the moment of contact includes an enlarged window displayed in step S120. 9 and 10 are examples of screens displayed when a finger touches. First, referring to FIG. 9, when the finger touches the position of the letter D in the enlarged window W while the access is maintained, the letter D is input and displayed on the input window ch. If, as shown in FIG. 10, the finger touches the position of the letter E in the enlarged window W while the access is maintained, it can be seen that the letter E is input and displayed on the input window ch. As such, after the input of a certain key is completed, fine vibration can be generated as a response of the completion of the input.

If, in step S140, the touch of an external object or body is not detected (No in step S140), or after the contact is performed (after step S150), or the end of contact and approach is detected (in step S160). YES '), the display of the screen displayed in step S120 is stopped, and the screen returns to the basic keypad screen (step S170). 11 is an example of a screen displayed when a finger is separated by more than a predetermined distance after contact. Referring to FIG. 11, after the input of the letter E is completed, the finger is moved beyond the predetermined distance and the end of the approach is detected, so that the display of the enlarged window W is stopped and the display returns to the basic keypad screen.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
