As shown in FIG. 7, the angle signal by the angle detecting sensor unit includes direction P1 information including an X-axis and a Y-axis component, which is represented by coordinates X1 and Y1.

Hereinafter, the operation and effects of the present invention will be described in detail with reference to the accompanying drawings.

3 and 4, according to the up, down, left and right direction mode or the arbitrary direction mode selection by the mode selection button 112 of the handheld device of the present invention, the control unit 130 of the present invention is a direction sensor unit ( The direction inputted by 111) is recognized by being divided into any direction including up, down, left, and right directions, or up, down, left, and right directions.

For example, when selecting the up, down, left and right direction mode through the mode selection button 112, the control unit 130 is the direction input by the direction sensor unit 111 in the direction closest to the up, down, left and right directions Recognizing or selecting an arbitrary direction mode through the mode selection button 112, the direction input by the direction sensor unit 111 is recognized in any direction including up, down, left and right directions.

5A, 5B, and 5C, when the left side of the direction sensor unit 111 shown in FIG. 5A is pressed, the sensor is shown as a dotted line in a state in which the real part of the normal state is pressed, as shown in FIG. 5B. The direction of the signal is changed to generate a direction signal corresponding to the inclination angle SS.

Alternatively, when the upper side of the direction sensor 111 shown in FIG. 5A is pressed, the angle of the sensor is changed and tilted as shown in FIG. 5C, such as a dotted line in which the actual part is pressed. The direction signal corresponding to the magnitude is generated.

As such, the direction change corresponding to the change in the state of the direction detecting unit 111, that is, the tilted state change is detected by the direction detecting unit 111, and the detection signal by the direction detecting unit 111 is detected. Is output to the signal processor 120.

The analog processing unit 121 of the signal processing unit 120 amplifies the signal from the direction sensor unit 111 to a signal level required at a later stage, and also removes noise included in the signal, and then, the signal The A / D converter 122 of the processor 120 converts the analog signal from the analog processor 121 into a digital signal and outputs the digital signal to the controller 130.

The control unit 130 holds the XY plane on which the direction sensor unit 111 is placed as an initial reference posture, and sets a reference posture according to a signal from the direction sensor unit 111 of the direction sensor unit 111. The correction is continuously performed in the current posture. The correction is performed by the controller 130 in real time on the current state of the direction detecting unit 111, that is, the inclined current state, according to a signal input through the signal processing unit 120. This is to accurately recognize, and to accurately recognize the pressing direction by the direction detecting sensor 111 using the current posture of the direction detecting sensor 111 as a reference posture.

In the corrected reference posture, when the direction sensor unit 111 is pressed, the tilted angle SS or RR corresponding to the pushed down and the coordinates X and Y of the tilted angle are output.

Next, the controller 130 determines whether the input signal is a valid direction signal in the corrected reference posture, which will be described with reference to FIG. 6.

Referring to FIG. 6, after the reference signal for each direction is corrected, the controller 130 determines whether the signal from the signal processor 120 is a valid signal. The state higher than Vref should be maintained for a preset time T, for example, the preset time T may be approximately 50 msec.

Here, the constant set time (T) is a time required for distinguishing whether the posture change due to intentional pressing on the direction sensor unit 111 or whether the posture change occurs due to unintentional shaking or the like.

Then, the controller 130 reads the direction included in the signal from the signal processing unit 120 according to the mode selected by the mode selection button 112, if the valid direction signal of the cursor in the decoded direction Control the movement

Referring to FIG. 7, the controller 130 recognizes a direction based on coordinate (X, Y) information included in a signal from the signal processor 120. For example, when the mode selection button 112 selects the up, down, left, and right directions, the controller 130 decodes the coordinates included in the signal from the signal processor 120 in the closest direction among the up, down, left, and right directions. do.

In this case, when the correct up, down, left, and right directions are not included, the input may be ignored or recognized as the closest direction. For example, the close direction may be determined as the magnitude of the absolute value of the X component and the Y component, that is, when X1 is larger than Y1 in the coordinates (+ X1, + Y1) included in the signal, the right direction is determined. If Y1 is larger than X1, it may be determined as an upward direction.

Alternatively, when a certain direction mode is selected by the mode selection button 112, the controller 130 reads coordinates included in the signal from the signal processor 120 in any direction including up, down, left, and right directions. do. Input to such arbitrary direction information is required, for example, in software such as games.

Here, the inclination angle is represented by the magnitude of the signal. When the magnitude of the signal is maintained higher than the reference voltage Vref for a preset time as described above, the direction detecting unit 111 is pressed in an arbitrary direction. That is, it is determined that the direction is artificially selected.

Accordingly, the display unit 140 moves and displays the cursor position on the screen under the control of the controller 130.

In the handheld device of the present invention as described above, it is possible to input an arbitrary direction according to the diversification of the software operated in the handheld device. With one button attached to the handheld device, four-way information is provided in units of 90 degrees. In addition to inputting, information about arbitrary direction selection can be input.

According to the present invention as described above, in a handheld device such as a mobile phone, a personal data input device (PDA), as well as input information for up, down, left, and right, it is possible to input information for any direction, such as a game In response to the diversification of the software, there is an effect of easily inputting information on any direction including up, down, left and right directions.
