Electronic device and method for controlling program thereof

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device and a program control method thereof, and more particularly to a method of controlling an operation of a program performed in an electronic device having an input means using a magnetic sensor moving in a two-dimensional plane.

In recent years, electronic devices have become smaller and smaller and have evolved to perform various functions in combination. For example, in the case of a portable telephone, recently, not only a call function but also a photographing function and a music playing function are included.

Various types of input means have been used to control the programs activated in the conventional electronic device. That is, a mouse, a touch pad, a click button, a click pad, and the like are used as input means of a conventional electronic device. In the case of a mouse or a touch pad, it is difficult to apply to a miniaturized electronic device because of its large size.

Recently, a number of click buttons have been put in place, and each program has been programmed to perform a corresponding action every time the click button is pressed to control the activated program. However, this has the disadvantage that the number of click buttons increases as the number of input signals required for controlling the program increases. For example, an electronic device includes four click buttons when four input signals are required for program control, and seven click buttons when seven input signals are required. However, when the number of click buttons increases, there is a problem in that the manufacturing cost is expensive.

On the other hand, a dome switch is used as a conventional click button. Therefore, there is a limit to reducing the size more than a certain size because sufficient space must be secured in order to mount the dome switch.

Accordingly, the present invention determines the movement signals output according to the movement of the operating member in the input means having an operating member that rotates or moves up, down, left, and right in a two-dimensional plane, and converts them into various types of input control signals to control the program. The present invention provides an electronic device capable of miniaturizing an electronic device, reducing a manufacturing cost, and controlling various programs in the device, and a program control method thereof.

When a signal is applied, the eighteenth and nineteenth input control signals are generated according to the variable vector of the axial movement signal, and when only the click signal is applied during the 30 to 300 signal input period, the twentieth input control signal is generated. After the click signal is applied, when the -X-axis movement signal, the + Y-axis movement signal and the -Y-axis movement signal are applied within a maximum 4 to 10 signal input period, the corresponding axial movement is performed.

Not only linear motion but also curved and circular motions are possible. When the external force is removed, the center portion 1141 may be naturally restored to the center point of the fixing portion 1143 by the pattern portion 1142.

Here, the pattern portion 1142 supports the central portion 1141 when the central portion 1141 moves or rotates by an external force, and when the external force is not applied (that is, the central portion 1141 does not move and rotate). The central portion 1141 is restored to its original position.

Therefore, the shape of the pattern portion 1142 is not limited to the above description, and various modifications are possible. For example, the pattern portion 1142 may be manufactured such that a single line is formed in a spiral shape (ie, a swirl shape) in a space between the center portion 1141 and the fixing portion 1143 along the periphery of the center portion 1141. In addition, the pattern portion 1142 may be manufactured from a plurality of meandering lines.

The fixing protrusion 1144 is fixed to the space between the magnet part 1120 and the operation member 1130 in a fitting form.

Through this, not only the magnet part 1120 may be fixed but also the movement of the operation member 1130 may be transmitted to the pattern part 1142 through the central part 1141, and the restoring force of the pattern part 1142 may be transmitted to the operation member 1130. ) And the magnet unit 1120.

It includes a plurality of magnetic sensors for detecting a change in the magnetic field according to the movement of the direction and outputs a corresponding Y-axis sensing signal (that is, ± Y coordinate value).

The apparatus may further include a controller (not shown) for amplifying the output of the magnetic sensor and combining the detected magnetic field. In the present embodiment, a sensor chip in which the plurality of magnetic sensors described above are one-chip is used as the sensor unit 1160. Of course, the present invention is not limited thereto, and the plurality of magnetic sensors may not be chipped, and the plurality of magnetic sensors may be spaced apart from each other in four directions (ie, up, down, left, and right directions) with respect to the magnet unit 1120.

In this embodiment, a magnetic element uses a Hall element whose output voltage changes in proportion to the magnetic flux density. The sensing signal output by the sensor unit 1160 of the present embodiment includes coordinate-related data (ie, movement-related data) of the magnet unit 1120 moved by the user. This forms a plurality of movement signals related to the movement of the magnet 1120, that is, the intermediate member 1140, through the sensing signal.

As a result, if it is not authorized, it is determined that there is no user's operation and does not perform a separate operation. However, if the movement signal and / or the click signal is applied as a result of the determination, an input control signal is generated through the applied movement signal and / or click signal coordination (S11). Hereinafter, various input control signals are generated through the movement signal and the click signal coordination in detail. Subsequently, the program is controlled using the generated various input control signals (S12).

Hereinafter, a method of controlling an operation of a program will be described based on the operations of the pointing control means 1100 and the pointer control module 2100.

The operating member 1130, the magnet part 1120, and the intermediate member 1140 of the present embodiment move on a two-dimensional plane to generate a movement signal. In addition, when the operation member 1130, the magnet part 1120, and the intermediate member 1140 descend and press the dome switch 1111, a click signal is generated. Hereinafter, the operation member 1130 will be described. This is because the magnet part 1120 and the intermediate member 1140 move together with the operation member 1130. In the following, movement of the operating member 1130 refers to movement of the center point of the operating member 1130.

Then, when a force is applied from the user, it moves up, down, left and right in the axial direction (± X axis and ± Y axis). In this case, the operation member 1130 may also move to a space between the shaft and the shaft. In this embodiment, as shown in FIG. 5, the moving space of the operating member 1130 is divided into four reference axis moving spaces (that is, A, B, C, D; see FIG. 5 (a)). That is, it divided into +/- X movement space (A, C) and +/- Y movement space (B, D). Through this, if the operating member 1130 moves to the + X-axis movement space A, the movement of the operating member 1130 is determined as + X-axis movement, and moved to the + Y-axis movement space B. In this case, it is decided by + Y-axis movement. In case of moving in the -X axis movement space (C), it is determined by movement in the -X axis direction. Determined by movement.

In addition, when a force is applied from the user, the operation member 1130 may perform the clockwise rotational movement and the counterclockwise rotational movement as well as the axial movement. In addition, when a force is applied from the user, it is moved in the lower direction of the plane rather than the plane direction. Of course, if the force applied from the user disappears by the intermediate member 1140 is restored to the initial position (center point).

As described above, the operation member 1130 of the present embodiment performs various movements, and the signal output due to the movement also has various values. In this embodiment, various signal values are used as input control signals for controlling the program.

The signal generated according to the movement of the operation member 1130 will be described with reference to FIG. 5.

First, as shown in FIG. 5A, the operating member 1130 may be lowered to click the dome switch 1111 to generate a click signal. That is, the pointing control means 1100 provides a click signal by the dome switch 1111 to the pointer control module 2100. The pointer control module 2100 generates a first input control signal using the click signal provided through the pointing control means 1100. The first input control signal is used to perform one of various operations of the program.

In addition, as shown in FIG. 5B, the operation member 1130 is moved on a plane, so that the + X-axis movement signal (that is, the right movement signal) and the -X-axis movement signal (that is, the left movement signal) are moved. , A + Y-axis movement signal (ie, an upward movement signal) and a -Y-axis movement signal (ie, a downward movement signal) can be generated. Due to the planar movement of the operation member 1130, the sensor unit 1160 provides the sensing signal (ie, the axial movement signal) of various levels to the pointer control module 2100. The pointer control module 2100 determines whether the current operating member 1130 has moved in the direction of ± X axis and ± Y axis with respect to the center point by using the provided axial movement signal, thereby providing the second to fifth input control signals. Generates one input control signal.

At this time, the pointer control module 2100 receives the axial movement signal continuously for a predetermined time (that is, every predetermined signal input period). That is, the pointer control module 2100 of the main body 2000 of the present embodiment receives a plurality of axial movement signals output from the pointing control means 1100 every predetermined time (5 to 1000 msec). For example, an axial movement signal is input every 20 msec (signal input period). Of course, the signal input cycle time for receiving the axial movement signal is not limited thereto, and may be larger or smaller than the range depending on the sensing sensitivity and the response sensitivity of the pointer control module 2100.

In addition, the positioning of the operation member 1130 is determined using a signal generated by the pointing control means 1100 according to the movement of the operation member 1130 during one signal input period. That is, in this embodiment, the axial movement signal according to the movement of the operation member 1130 may be determined according to the output of the sensor. That is, in the pointing control means 1100 of the present embodiment, four sensors for outputting a plurality of sensing signals are positioned on the X and Y axes, respectively. In addition, the signal output level of the sensor is varied according to the magnet portion 1120 moved by the operation member 1130. That is, for example, if the operating member 1130 moves in the + X axis direction, the output of the sensor located on the + X axis line is greatly increased, and the output of the sensor located on the -X axis line is greatly reduced, and also The output of the sensor on the ± Y axis is also reduced.

As described above, the level of the plurality of signals output from the pointing control means 1100 changes as the operation member 1130 moves, and the + X-axis movement signal and the -X-axis movement signal according to the changed levels of the signals. , + Y-axis movement signal and -Y-axis movement signal are generated. Accordingly, the + X-axis movement signal refers to the output signal of the sensor output when the operation member 1130 is located in the + X-axis movement space A, and the -X-axis movement signal is the operation member 1130. ) Is an output signal that is output when positioned in the -X axis movement space C, + Y axis movement signal is an output signal when the operation member 1130 is located in the + Y axis movement space B, The -Y axis movement signal is an output signal when the operation member 1130 is located in the -Y axis movement space D. FIG. In this case, as described above, the pointer control module 2100 according to the present embodiment receives one signal every one signal input period (for example, about 20 msec). Accordingly, the pointer control module 2100 recognizes this as an axial movement signal when the same signal is applied for at least 4 to 6 signal input periods. For example, when the operation member 1130 moves to the + X axis moving space, the pointing control means 1100 outputs a + X axis direction moving signal at every signal input period. In this case, the pointer control module 2100 generates a second input control signal corresponding to the + X-axis movement signal when the same + X-axis movement signal is applied for about five signal input periods.

Here, the reason why the minimum signal input period is set in the above range is as follows. If it is smaller than the range, the basis for judgment is too short to be recognized as an axial movement signal. This may cause a problem of performing an operation different from the intention of the user. It is preferable that the same signal is applied to at least one signal input period of the above range. The value of the upper limit is not limited because it can be maintained continuously by the user. At this time, 1000 signal input period can be set as the upper limit. This takes into account the operation state and can prevent generation of an infinite axial movement signal.

In addition, as shown in FIG. 5C, after moving the operation member 1130 on a plane and lowering it, the dome switch 1111 is clicked, and the + X-axis movement click signal, the -X-axis movement click signal, The + Y-axis movement click signal and the -Y-axis movement click signal can be generated. In this case, the pointer control module 2100 determines which of the sixth to ninth input control signals is determined by determining whether a click is performed after the current operation member 1130 is moved in a direction of ± X axis and ± Y axis based on the center point. Generates an input control signal.

That is, when a click signal corresponding to the click of the dome switch 1111 is applied after the axial movement signal is generated according to the movement of the operation member 1130, this is ± X-axis movement click signal or ± Y-axis movement. It recognizes as a click signal and generates an input control signal corresponding thereto. At this time, the axial movement signal is determined according to the output of the sensor as described above, the click signal is determined according to the dome switch. For example, as described above with reference to FIG. 5B, when the operating member 1130 is located in the + X axis movement space, the pointing control means 1100 outputs the + X axis direction movement signal. Subsequently, when the click signal is not generated for a predetermined time (for example, 1 to 100 signal input periods), the pointer control module 2100 recognizes this as a + X-axis movement signal and generates a second input control signal. . However, if a click signal is generated after the + X axis direction movement signal is applied, the pointer control module 2100 recognizes this as a click after the + X axis direction movement and generates a sixth input control signal.

In addition, as shown in FIG. 5D, the operation member 1130 is lowered to click the dome switch 1111, and is moved in a plane to move the + X axis click signal, the -X axis click signal, and the + Y axis click. Signal and a -Y-axis click signal can be generated. At this time, the pointer control module 2100 determines whether the click signal is maintained and whether the operation member 1130 is moved in the direction of ± X axis and ± Y axis relative to the center point, thereby determining one of the tenth to thirteenth input control signals. Generates an input control signal. For example, as illustrated in FIG. 5A, when the dome switch 1111 is clicked on, a click signal is generated. However, when the axial movement signal is not applied for a predetermined time (for example, 3 to 100 signal input periods), the signal is recognized as a click signal to generate a first input control signal. Here, the setting after the at least three signal input periods is because a motion that the user does not intend during the initial click operation may occur. However, if the axial movement signal is applied after the click signal is generated, it is recognized as an axial click signal to generate an input control signal corresponding thereto. That is, after the click signal is input, when the + X-axis movement signal is applied, the signal is recognized as the X-axis click signal to generate a tenth input control signal.

In addition, as shown in FIG. 5E, the operating member 1130 may be rotated on a two-dimensional plane to generate a clockwise rotation signal and a counterclockwise rotation signal. The pointer control module 2100 may generate the 14th and 15th input control signals by determining the rotation signals.

As described above, the pointer control module 2100 according to the present embodiment continuously receives a movement signal at every signal input period. Therefore, it is determined whether the operation member 1130 is rotated according to the output of the pointing control means 1100 applied during the predetermined signal input period. That is, when the operation member 1130 moves, the output of the sensors located on each axis varies according to the movement. In this case, when the output of the sensor continuously applied for up to 4 to 10 signal input periods is not the same value, it is recognized as a rotation, and the current operating member 1130 is clockwise or anticlockwise using the vector value of the sensor output. It determines whether it moves clockwise. At this time, limiting the maximum range to the section for rotation recognition causes a problem of performing an operation different from the intention of the user when it becomes larger than the section. Of course, the lower limit is 1. Thus, the magnitude of the maximum value may have a smaller value or may have a large value. That is, the maximum value may be 5 or less or greater than 10. This may vary depending on the set time of the signal input period. When the signal is applied within the time range of about 40msec to 2sec it can be recognized as a rotation.

Here, the coordinates of the operating member 1130 by the output of the sensor during the three signal input periods, for example, by the movement of the operating member 1130 with respect to rotation, are (1.0), (0.5, 0.5) and (0, 1). ), The pointing control means 1100 recognizes that the actuating member 1130 moves counterclockwise and generates a fifteenth input control signal. Here, the signal applied to the pointer control module 2100 may be an axial movement signal grouping the sensor output signal as well as the output signal of the sensor. This means that if the operating member 1130 is in the axial movement space for the specified signal input period, it is recognized as moving in the corresponding axial direction, and if the operating member 1130 is out of the axial movement space for the specified signal input period, it is rotated. I can recognize it.

Further, as shown in FIG. 5F, the operating member 1130 is lowered to click the dome switch 1111 and then rotated on a two-dimensional plane to generate a clockwise rotation click signal and a counterclockwise rotation click signal. can do. In this way, the pointer control module 2100 may generate the sixteenth and seventeenth input control signals by determining the rotation click signals. This occurs when the axial movement signal is applied while the click is held (i.e., the state where the click signal is continuously applied).

As such, about 17 input control signals can be generated using the movement of the operating member 1130 of the pointing control means 1100 and the click of the dome switch 1111 according to the present embodiment. Can be used as a control signal. In this way, the number of input control signals can be increased by combining the movement signal and the click signal without increasing the dome switch, thereby reducing the number of dome switches that can be used for program control using the existing dome switch. Cost) and is advantageous for miniaturization and slimming.

Of course, the present invention is not limited thereto, and the pointer control module 2100 may determine that a click signal is input after inputting a rotation signal according to the rotation of the operation member 1130, and generate the 18th and 19th input control signals accordingly. . In addition, the pointer control module 2100 may generate the twentieth input control signal by recognizing when the click signal is applied for a long time (for example, 30 to 300 signal input periods). In addition, when the axial movement signal is applied within a predetermined time (for example, 1 to 100 signal input periods) after the click signal is applied, the twenty-first to twenty-fourth input control signals may be generated according to the click signal and the axial movement signal. . The preceding tenth to thirteenth input control signals are signals generated when the axial movement signal is applied while the click signal is maintained (that is, the state where the click signal is continuously applied). However, the twenty-first to twenty-fourth input control signals are generated when an axial movement signal is applied after the short click signal. In addition, when the rotation signal is applied within a predetermined time (for example, 1 to 100 signal input periods) after the click signal is applied, the 25 th and 26 th input control signals may be generated according to the rotation direction of the rotation signal. . In addition, when the double click signal is applied, it may be generated as the twenty-seventh input control signal. That is, it is generated when the click signal is applied at least twice within a predetermined time (for example, 1 to 100 signal input periods). Of course, the case where the click signal is applied continuously is excluded.

Hereinafter, a method of controlling the music reproduction program displayed on the screen of FIG. 2 by the pointing control means 1100 and the pointer control module 2100 according to the present embodiment will be described in detail with reference to the flowchart of FIG. 7. Here, the operation of the pointer control module 2100 will be described.

Referring to FIG. 7, first, it is determined whether a click signal is applied (S100). That is, if there is no signal input for a predetermined time after the click signal by the click of the dome switch 1111 is applied, an operation corresponding to the click is performed. That is, the play or stop operation is performed (S110). In this case, the above operation is performed according to the level of the input control signal generated by the pointer control module 2100 according to the signal applied from the pointing control means. That is, the operation to be performed in the program is stored in advance in the memory 2200 according to the level of the input control signal, and the information related to the operation is loaded together when the program is executed.

As a result, when the click signal is not applied, it is determined whether the operation member 1130 is moved (S120). Then, it is determined whether to move or rotate (S130). Here, when the sensor output (i.e., the axial movement signal) has a different value for 5 to 10 signal input periods, it is determined as rotation, and the same value (within an error range of about ± 10%) during the signal input period. In case of having, it is determined as a move.

If it is determined that the rotation, the operation of adjusting the volume of the program according to the rotation direction is performed (S140). That is, in the case of rotation in the clockwise direction, the operation of increasing the volume is performed, and in the case of rotation in the counterclockwise direction, the operation of decreasing the volume is performed.

If it is determined that the movement, the movement direction is determined (S150). That is, according to the axial movement signal, it determines in which axial direction the movement member 1130 has moved in the ± X axis or the ± Y axis. Next, it is determined whether a click signal is input (S160). Whether or not the click signal is input is determined that the click signal is not applied when there is no click signal for about 5 to 300 signal input periods after the movement signal is generated, and when the click signal is applied during the input period, it is determined that the click signal is applied.

Here, if the click signal is applied, the music skip operation is performed according to the moving direction (S170). That is, when the + X-axis movement signal is applied and the click signal is applied later, the music is transferred to the front song. When the -X-axis movement signal is applied and the click signal is applied, the back music is performed. Perform the song turning operation. As a result of the determination, when the click signal is not applied, the forward or the forward operation is performed according to the moving direction (S180). That is, when only the + X-axis movement signal is applied, the forward winding operation is performed. When only the -X-axis movement signal is applied, the forward winding operation is performed.

In the above-described embodiment, an electronic device having an input unit, a main body unit, and a display unit has been described. However, some elements of the input unit and some elements of the main body may be combined to form a pointer device for controlling the pointer on the screen. In other words, this means that some elements of the input portion and some elements of the body portion can be manufactured integrally.

In addition, in the case of the pointer control module of this embodiment, it can be positioned (programmed) on the control chip IC which is a main body portion in the form of program code, and can also be recorded on a predetermined recording medium. Of course, a pointer control module in the form of program code may be recorded in the pointing control means. At this time, the recording medium is programmed and can be read by a computer.

As described above, the pointer control module of the present embodiment generates various types of input control signals through the combination of the movement of the operating member and the click signal generated by the dome switch pressed by the operating member, and the generated input control signal. To control the behavior of the program. This can reduce the number of dome switches used in the conventional program operation control.

However, the present invention is not limited thereto, and the pointer control module may move the pointer on the screen through a movement signal generated according to the movement of the operation member. That is, in the present embodiment, a pointer (mouse or cursor) is positioned on the screen according to the mode selection signal applied to the pointer control module, and the operation of the program may be controlled by clicking the pointer and the dome switch. When the pointer is located on the screen, as described above, the pointer moves in the X-axis direction and the Y-axis direction on the screen according to the movement of the operating member, the magnet part, and the intermediate member, and moves to the control area for program control displayed on the screen. Is located. Subsequently, when the dome switch is clicked, a command corresponding to the area where the current pointer is located may be executed.
