Description

Information input method of capacitive type keyboard {INFORMATION INPUT METHOD OF CAPACITVE TYPE KEYBOARD}

The present invention relates to an information input method for inputting letters or numbers on a capacitive keyboard.

In general, a pressure type keyboard including an elastic spring or a dome switch disposed below the key button does not press the key button of the keyboard unless a certain amount of force is applied even if the user puts his or her hand on the keyboard during key input. The input is stopped.

On the other hand, recently, the capacitive keyboard, which is clean in hygiene and advantageous in terms of design, has not received dust between key buttons. The capacitive keyboard provides a touch area for inputting letters or numbers on an upper surface of which a finger is touched, and letters, numbers, or symbols corresponding to the touch area are printed on the touch area. The capacitive keyboard may generate an input signal for inputting letters or numbers corresponding to the touch areas independently according to a button operation in which a body part such as a finger contacts the touch areas.

However, in the capacitive keyboard described above, the user should take his / her hands off the keyboard even when the user thinks for a while or reads a document for input. Otherwise, if the user puts his hand on the keyboard as it is, the capacitive keyboard continuously inputs letters or numbers corresponding to the touch area finally touched.

Thus, the user is inconvenient to remove his / her hand on the keyboard every time the key input is interrupted, which may delay the return to the key input operation again, which may cause the delay of the overall key input operation.

The present invention provides an information input method of a capacitive keyboard that can prevent the unintentional input of letters or numbers even when the user puts his hand on the keyboard for a while during a key input operation using the capacitive keyboard.

According to the present invention, when a user puts his / her hand up for a while, the user deletes an incorrectly inputted letter or number, and when the user starts inputting again, the user immediately starts inputting without deleting the wrongly inputted letter or number. Provides an information input method of a capacitive keyboard.

According to an exemplary embodiment of the present invention for achieving the above object of the present invention, it provides a plurality of touch areas for inputting letters or numbers, the touch area according to the button operation that the body part contacts the touch area In the information input method of the capacitive keyboard for inputting letters or numbers corresponding to each other independently, the method includes inputting letters or numbers in response to a button operation touching a touch area, and the touch lasts for a predetermined time. In the case of the standby mode, switching to the standby mode ignoring the input after the button operation, and in the case of the standby mode, canceling the input of the finally inputted letters or numbers.

In the present specification, the letters or numbers may mean all characters included in various languages such as English, French, Japanese, as well as Korean, and may be used to include all symbols, pictures, punctuation marks, etc. in addition to letters and numbers. Can be.

On capacitive keyboards, users need to take their hands off the keyboard when they think about something for a while or read a document for input. Otherwise, if the user puts his hand on the keyboard as it is, the capacitive keyboard continuously inputs letters or numbers corresponding to the touch area finally touched.

However, in the information input method according to the present invention, even if the user puts his hand on the keyboard until a certain time is exceeded, if the contact is maintained for a predetermined time or more in the touch area, the input after the last button operation is ignored. In addition, even if the user rests his hand on the keyboard, unintended input of characters or sequential letters may be restricted. For reference, the predetermined time may be set to about 1 second or several seconds according to the designer's intention, and the present invention is not limited by the predetermined time.

In particular, when the user places his or her hand on the keyboard for a certain period of time, the user cancels the input of the last entered letter or number so that the user touches the hand on the keyboard before entering the intended letter or number again. You can avoid the hassle of starting off with letters or numbers that were mistyped or unintended at the time of placement. Here, the "cancel" may be implemented by the capacitive keyboard transmitting a signal corresponding to the backspace in order to cancel the input of the finally inputted letters or numbers.

On the other hand, if the user keeps his hand on the touch area, letters or numbers corresponding to them may be continuously input. If there are a plurality of letters or numbers finally inputted as described above, all of the plurality of inputs may be cancelled. have.

Accordingly, the user does not need to remove his / her hand from the keyboard whenever the letters or numbers are not input and move the hand to the upper portion of the keyboard for the input operation again, and shorten the working time.

In addition, in the situation in which the standby mode is maintained, when the contact of the body part is released from the touch area, the standby mode may be released, and the user may input a desired letter or number again.

In the information input method of the capacitive keyboard of the present invention, if the user puts his or her hand on the keyboard for a predetermined time during a key input operation, it enters a standby mode that ignores the input after the button operation to prevent an unintended entry of letters or numbers. can do.

The information input method of the capacitive keyboard of the present invention cancels the input of letters or numbers finally input in the standby mode, so that the user places his hand on the keyboard before inputting the letters or numbers intended by the user again. There is no hassle to start by erasing letters or numbers that were mistyped or unintended at the time.
