In this case, a gap is formed between the rod portion and the through hole to allow two-dimensional movement of the magnet portion 1120. That is, the magnet portion 1120 moves in the circular through hole of the covering portion 1150.

As described above, the magnet portion 1120, the actuation member 1130, the intermediate member 1140, and the cover portion 1150 are located on the substrate 1110, and the sensor portion 1160 is located on the bottom end of the substrate 1110, as shown in FIG. The sensor portion 1160 outputs a sensing signal by detecting a change in the magnetic field caused by the magnet portion 1120 at the top end of the substrate 1110.

That is, the sensor portion 1160 detects the movement (two-dimensional movement) of the magnet portion 1120 in the upper, lower, left, and right directions. The sensor portion 1160 includes a plurality of magnetic sensors configured to output a x-axis sensing signal (ie, a ±x-axis coordinate value) in accordance with a change in a magnetic field caused by movement of the magnet portion 1120 in the x-axis direction (magnetic) A sensor, and a plurality of magnetic sensors configured to output a y-axis sensing signal (ie, a ±y-axis coordinate value) according to a change in a magnetic field caused by the magnet portion 1120 moving in the y-axis direction.

In addition, the control unit (not shown) amplifies the output signal of the magnetic sensor of the sensor portion 1160 and detects the entire magnetic field change by using the amplified output signal. In the present invention, the magnetic sensor of the sensor portion 1160 is modulated in a sensor wafer. However, the invention is not limited thereto. That is to say, the magnetic sensors can be arranged around the magnet portion 1120 in four positions (i.e., up, down, left, and right directions) instead of modulating the magnetic sensor. In this case, the magnetic sensor can be symmetrical with the central portion of the magnet portion 1120.

In this embodiment, the magnetic sensor of the sensor portion 1160 may be a hole device, a semiconductor magnetic resistive device, or a magneto magnetic resistive device or a giant magnetic device. Giant magneto resistive (GMR). The electrical characteristics of the magnetic sensor can vary depending on the change in the magnetic field applied to the magnetic sensor. In the present embodiment, the magnetic sensor is a hole device whose output voltage varies in proportion to the density of magnetic flux. In the present invention, the sensing signal output from the sensor portion 1160 includes coordinate data (moving data) of the magnet portion 1120 moved by the user. That is, the sensing signal is a signal (moving signal) that provides movement about the magnet portion 1120 (ie, the intermediate member 1140).

Therefore, in the present embodiment, a plurality of mobile signals generated in response to the movement of the magnet portion 1120 and the intermediate member 1140 and a keystroke signal generated in response to the keystroke of the dome switch 1111 can be generated. The control signal is input to control the operation of the program by using an input control signal.

Referring to Figure 6, the method of controlling the program will be described below. Based on the user's operation, it is determined whether a mobile signal and/or a keystroke signal is applied (S10). If it is decided that no mobile signal and/or keystroke signal is applied, it is determined that the user has not operated and the action has not been performed. If it is decided to apply a mobile signal and/or a keystroke signal, the input control signal is generated by combining the mobile signal and the keystroke signal (S11). By combining the mobile signal and the keystroke signal, various input control signals can be generated, which will be described in detail later. Next, the program is controlled by using the input control signal (S12).

Hereinafter, a method of controlling the operation of the program will be described, mainly regarding the operations of the index control unit 1100 and the index control module 2100.

In the present embodiment, the actuating member 1130, the magnet portion 1120, and the intermediate member 1140 are two-dimensionally moved in a plane, and a mobile signal is generated in response to the movement thereof. If the dome switch 1111 is pressed while the actuation member 1130, the magnet portion 1120, and the intermediate member 1140 are moved downward, a keystroke signal is generated. The actuation member 1130 will be described in detail below. The actuating member 1130, the magnet portion 1120, and the intermediate member 1140 are moved together. In the following description, "moving" of the actuating member 1130 means movement of the center point of the actuating member 1130, and the displacement range of the actuating member 1130 means the displacement range of the center point of the actuating member 1130 .

In the present embodiment, in the case where the user operates the actuating member 1130, the actuating member 1130 moves in a circular two-dimensional plane defined by the covering portion 1150, and the x-axis and the y-axis represent the two-dimensional plane. position. Additionally, the actuation member 1130 can be moved downward from a two dimensional plane.

In the absence of an external force acting on the member 1130, the actuation member 1130 is located at the center of its displacement range by the intermediate member 1140.

If the user applies an external force to the actuating member 1130, the actuating member 1130 can move in the up, down, left, and right directions (±y-axis and ±x-axis directions). At this time, the actuation member 1130 can move over the area defined between the x-axis and the y-axis. In the present invention, referring to FIG. 5, based on the ±45 degree reference line defined from the x-axis and the y-axis, the displacement range of the actuating member 1130 is divided into four axial displacement regions (refer to FIG. 5(a) A, B, C and D). In other words, the displacement range is divided into ±x-axis displacement range areas A and C, and ±y-axis displacement range areas B and D. If the actuating member 1130 moves within the +x axis displacement range region A, it is determined that the actuating member 1130 is moved in the +x axis direction. If the actuating member 1130 moves within the +y-axis displacement range region B, it is determined that the actuating member 1130 is moved in the +y-axis direction. If the actuating member 1130 moves within the -x axis displacement range region C, it is determined that the actuating member 1130 is moved in the -x axis direction. If the actuating member 1130 moves within the -y-axis displacement range region D, it is determined that the actuating member 1130 is moved in the -y-axis direction.

Further, the actuation member 1130 can be rotated clockwise or counterclockwise depending on the user's operation. Further, the actuation member 1130 can be moved downward from the two-dimensional plane according to the user's operation. If the external force acting on the actuating member 1130 is removed, the actuating member 1130 returns to its original position (center point).

As described above, the actuation member 1130 is moved in various directions or manners such that the sensed signals measured in accordance with the movement of the actuation member 1130 can have various values. In this embodiment, these various signal values are used to generate an input control signal for controlling the executed program.

The signal generated in accordance with the movement of the actuating member 1130 will be described in detail below with reference to FIG.

Referring to FIG. 5(a), in the case of pressing the actuating member 1130, a keystroke signal can be generated. That is, in the case of the keystroke dome switch 1111, the index control unit 1100 outputs a keystroke signal to the index control module 2100. The index control module 2100 generates a first input control signal by using a keystroke signal received from the indicator control unit 1100. Then, according to the first input control signal, one of a plurality of functions of the program can be executed.

Referring to FIG. 5(b), when the actuating member 1130 moves on a two-dimensional plane, a +x axis movement signal (right movement signal), an -x axis movement signal (left movement signal), and a +y axis movement can be generated. Signal (up mobile signal) and -y axis mobile signal (lower mobile signal). When the actuation member 1130 moves on a two-dimensional plane, the sensor portion 1160 can output a sensing signal (axial movement signal) having various levels to the index control module 2100. By using the axial movement signal, the index control module 2100 determines that the movement direction of the actuation member 1130 from the center point is one of the ±x axis and the ±y axis direction. Then, based on the result of the determination, the indicator control module 2100 outputs one of the second input control signal to the fifth input control signal.

At this time, the indicator control module 2100 (at a predetermined signal input frequency) successfully receives the axial movement signal. In the present embodiment, the indicator control module 2100 of the main body unit 2000 receives the axial movement signal from the index control unit 1100 at a predetermined interval (about 5 msec to about 1000 msec). For example, at an interval of 20 msec (during signal input), the indicator control unit 2100 can receive an axial movement signal. However, the input period of the axial movement signal is not limited to this. The signal input period can be increased or decreased according to the sensitivity of the sensor portion 1160 and the response sensitivity of the indicator control module 2100.

During the given signal input, the position of the actuating member 1130 is identified by employing the signal output from the index control unit 1100 in accordance with the movement of the actuating member 1130. That is, in the present invention, the axial movement signal can be determined by the sensing signal output according to the movement of the actuation member 1130. More specifically, the indicator control unit 1100 includes four sensors configured to generate a plurality of sensing signals, and two sensors are disposed along the x-axis, and the other two sensors are disposed along the y-axis . The level of the sensing signal of each sensor varies according to the position of the magnet portion 1120, and the magnet portion 1120 moves together with the actuating member 1130. For example, if the actuation member 1130 is moved in the +x axis direction, the level of the sensing signal of the sensor located on the +x axis is greatly increased, and the sensing signal of the sensor on the -x axis is The level is greatly reduced. In addition, the level of the sense signal of the sensor located on the +y axis and the -y axis is greatly reduced.

In this manner, according to the movement of the actuation member 1130, the level of the sensing signal output from the index control unit 1100 is changed, and the +x axis movement signal and the -x axis movement signal are generated according to the change of the sensing signal. , +y axis movement signal and -y axis movement signal. That is, the +x axis movement signal is a signal generated when the actuation member 1130 is moved in the +x axis movement area A, and the -x axis movement signal is the case where the actuation member 1130 is moved in the -x axis movement area C. The generated signal. The +y-axis movement signal is a signal generated when the actuation member 1130 is moved in the +y-axis movement region B, and the -y-axis movement signal is a signal generated when the actuation member 1130 is moved in the -y-axis movement region D. . As described above, the indicator control module 2100 of the present invention receives signals during each signal input period (e.g., about 20 msec). Therefore, for example, if the indicator control module 2100 receives the same axis motion signal during at least 4 to 6 signal input periods, the indicator control module 2100 determines that the signal is an axial motion signal. For example, when the actuation member 1130 moves in the +x axis movement area A, the indicator control unit 1100 outputs a +x axis movement signal during each signal input. At this time, if the +x axis movement signal is successfully input to the indicator control module 2100 during about five signal input periods, the indicator control module 2100 generates a second input control signal in response to the +x axis movement signal.

The minimum number of signal input periods for determining the axial movement of the actuating member 1130 is set to the above range for the following reason. If the minimum number of signal inputs is too small, an axial movement signal can be generated in response to very small movements. In this case, an unexpected operation can be performed. Thus, the minimum number of signal input periods can be set to the above range. Since the user can hold the actuation member 1130 in the same movement area, the maximum number of signal input periods is not set. However, the maximum number can be set to 1000. In this case, the generation of an infinite axial movement signal can be prevented during the operation of the electronic device.

Referring to FIG. 5(c), by actuating the member 1130 to move on the two-dimensional plane and pressing the actuation member 1130 to key the dome switch 1111, a +x axis movement keystroke signal, an -x axis movement key can be generated. The semaphore, the +y axis move keystroke, and the -y axis move keystroke. In this case, the indicator control module 2100 determines one of the +x axis direction, the -x axis direction, the +y axis direction, and the -y axis direction, and the actuation member 1130 precedes the keystroke dome switch 1111. The determined direction moves, and then, based on the determined result, the indicator control module 2100 generates one of the sixth input control signal to the ninth input control signal.

That is, if a keystroke signal is generated in response to a keystroke of the dome switch 1111 after generating an axial movement signal in response to the axial movement of the actuation member 1130, the sequential signal is recognized as + The x-axis move keystrokes, the -x-axis move keystrokes, the +y-axis move keystrokes, and the -y-axis move keystrokes, and generate corresponding input control signals. At this time, according to the above sensing signal, the axial movement signal is determined, and the keystroke signal is determined based on the state of the dome switch 1111. For example, as shown in (b) of FIG. 5, if the actuation member 1130 is moved in the +x axis movement region A, the index control unit 1100 generates a +x axis movement signal. Therefore, if a keystroke signal is not generated for a predetermined time (for example, 1 to 100 signal input periods), the index control module 2100 recognizes that the +x axis movement signal is the +x axis movement signal and generates the second input control signal. However, if a keystroke signal is generated within a predetermined time after the +x axis movement signal is generated, the indicator control module 2100 recognizes that the sequence signal is a +x axis movement keystroke signal and generates a sixth input control signal.

Referring to FIG. 5(d), by pressing the actuating member 1130 to key the dome switch 1111, a +x axis keystroke signal, an -x axis keystroke signal, a +y axis keystroke signal, and a -y axis can be generated. The keystroke signal and the actuating member 1130 are moved in a two dimensional plane. At this time, the index control module 2100 determines one of the +x axis direction, the -x axis direction, the +y axis direction, and the -y axis direction, and the actuation member 1130 moves in the determined direction to generate the tenth input. Control signal to one of the thirteenth input control signals. For example, as shown in (a) of FIG. 5, if the dome switch 1111 is clicked, a keystroke signal is generated. Therefore, if an axial movement signal is not generated for a predetermined time (for example, 3 to 100 signal input periods), the indicator control module 2100 recognizes the keystroke signal as a keystroke signal and generates a first input control signal. However, if an axial movement signal is generated within a predetermined time after the keystroke signal is generated, the indicator control module 2100 recognizes the sequence signal as an axial keystroke signal and generates a corresponding input control signal. That is, for example, if the +x axis movement signal is generated after the keystroke signal is generated, the sequence signal is recognized as the +x axis keystroke signal, and the tenth input control signal is generated.

Referring to FIG. 5(e), by rotating the actuating member 1130 on a two-dimensional plane, a clockwise rotation signal and a counterclockwise rotation signal can be generated. The indicator control module 2100 can generate the fourteenth and fifteenth input control signals in response to the rotation signals.

As described above, in the present embodiment, the index control module 2100 successfully receives the mobile signal during each signal input. Therefore, it is possible to determine whether or not the actuation member 1130 is rotated based on the signal output from the index control unit 1100 during the predetermined signal input period. More specifically, in the case of moving the actuating member 1130, the level of the signal output from the sensors located on the respective axes has changed. At this time, if the mobile signal is successfully generated during no more than 4 to 10 signal input, it is decided to rotate the actuating member 1130. Next, based on the vector value of the motion signal, it is determined whether the actuation member 1130 is rotated clockwise or counterclockwise. The maximum number of signal input periods for determining the rotation of the actuating member 1130 can be set to the above range for the following reason. If the maximum number of signal input periods is greater than the above range, an unexpected operation can be performed. The minimum number can be 1. Alternatively, the maximum number can be less than or greater than the above range. For example, the maximum number can be 5 or less, or greater than 10. The maximum number can vary depending on the length of the signal input period. Thus, if a different signal is generated over a time range of about 40 msec to about 2 sec, it can be determined that the actuating member 1130 has been rotated.

For example, the actuation member 1130 is moved during three signal inputs, and if the output sensing signal indicates that the coordinates of the actuation member 1130 are changed in the order of (1, 0), (0.5, 0.5), and (0, 1). The indicator control module 2100 can determine that the actuation member 1130 is rotated counterclockwise and generate a fifteenth input control signal. At this time, in addition to the sensing signals (signals output from the sensors), the axial movement signals generated by grouping the sensing signals as described above may be input to the index control module 2100. Thus, if the actuation member 1130 is in the axially moving region for a predetermined signal input period, then the actuation member 1130 can be determined to move in a corresponding axial direction, and if the actuation member 1130 is from the axis during a predetermined signal input. Upon disengagement from the moving area, it can be determined that the actuation member 1130 has been rotated.

Referring to FIG. 5(f), by pressing the actuation member 1130 to key the dome switch 1111, a clockwise rotation keystroke signal and a counterclockwise rotation keystroke signal can be generated, and the actuation is rotated on a two-dimensional plane. Member 1130. The indicator control module 2100 can generate the sixteenth and seventeenth input control signals in response to the rotary keystrokes. In the case where the dome switch 1111 is in the keyed state (i.e., in the case where the keystroke signal is continuously output), if the axial movement signal is changed, the sixteenth and seventeenth input control signals are generated.

As described above, in the present embodiment, about 17 input control signals can be generated according to the movement of the actuating member 1130 and the keystroke of the dome switch 1111, and the input control signal can be used as an input control for the operation of the control program. Signal. That is to say, by combining the mobile signal and the keystroke signal, the number of input control signals can be increased without increasing the size of the dome switch 1111, so that fewer dome switches and smaller dome switches can be used. Control the operation of the program. Thereby, the price (manufacturing cost) of the electronic device can be reduced, and the electronic device can have a small size as well as a thin shape.

In addition, in the case of receiving the rotary keystroke signal according to the rotation of the actuating member 1130 and the keystroke of the dome switch 1111, the index control module 2100 can generate the eighteenth input control signal and the nineteenth input control signal. In addition, if only a keystroke signal is input to the indicator control module 2100 during a long period of time (eg, 30 to 300 signal input), the indicator control module 2100 may generate a twentieth input control signal. In addition, if the axial movement signal is applied to the indicator control module 2100 after a predetermined time (for example, 1 to 100 signal input periods) after the keystroke signal is input to the index control module 2100, according to the key The index control module 2100 can generate the twenty-first to twenty-fourth input control signals. As described above, the tenth input control signal to the thirteenth input control signal are signals generated when an axial movement signal is applied in the case of a keystroke signal (that is, in the case where a keystroke signal is continuously applied). However, the twenty-first input control signal to the twenty-fourth input control signal is a signal generated when an axial movement signal is applied in a short time after the keystroke signal is applied. In addition, if a rotation signal is applied within a predetermined time (for example, 1 to 100 signal input period) after the keystroke signal is applied, the index control module 2100 can generate the second according to the rotation direction detected from the rotation signal. The fifteenth and twenty-sixth input control signals. In addition, the indicator control module 2100 can generate the twenty-seventh input control signal in the case of applying a double-click signal. That is, if at least two keystroke signals are applied within a predetermined time interval, a twenty-seventh input control signal can be generated. However, in the case where the keystroke signal is continuously applied, the twenty-seventh input control signal may not be generated.

Then, referring to the flowchart of FIG. 6, the method of controlling the music playing program in FIG. 2 by the index control unit 1100 and the index control module 2100 will be described in detail. The details will be described below based on the operation of the index control module 2100.

Referring to FIG. 7, it is determined whether to output a keystroke signal (S100). More specifically, if the dome switch 1111 outputs a keystroke signal and does not input a signal at a predetermined time, an action corresponding to the keystroke signal is performed. For example, regeneration or stop can be performed (S110). At this time, according to the level of the input control signal generated by the index control module 2100 in response to the signal received from the index control unit 1100, a current operation such as regeneration or stop is performed. That is to say, the operation rule of the program prepared in accordance with the level of the input control signal has been previously stored in the memory 2200, and in the case of executing the program, the operation rule is downloaded.

If it is decided that the keystroke signal is not output, it is decided whether or not to move the actuating member 1130 (S120). If the actuating member 1130 is moved, it is decided to move or rotate the actuating member 1130 (S130). More specifically, if the sensing signals (ie, the axial movement signals) output during the 5 to 10 signal input periods have different values, it is determined that the actuation member 1130 is rotated, and if the sensing signal has substantially The same value (within an error range of about ±10%) determines that the actuation member 1130 is moved.

In the case where it is determined that the actuating member 1130 is rotated, the volume of the program is adjusted in accordance with the rotational direction of the actuating member 1130 (S140). For example, if the actuation member 1130 is rotated clockwise, the capacity of the program is increased, and if the actuation member 1130 is rotated counterclockwise, the capacity of the program is reduced.

When it is determined that the actuation member 1130 is moved, the direction of movement is determined (S150). More specifically, based on the axial movement signal, the moving direction of the actuating member 1130 is determined in the +x axis direction, the -x axis direction, the +y axis direction, and the -y axis direction. Thereby, it is determined whether or not a keystroke signal is input (S160). More specifically, if there is no keystroke signal in about 5 to 300 signal input periods after the mobile signal is generated, it is decided that the keystroke signal is not input, and if about 5 to 300 are generated after the mobile signal is generated. During the signal input period, there is a keystroke signal, and it is determined that the keystroke signal is input.

In the case where the keystroke signal is input, the previous music or the next music (S170) is selected according to the direction information of the mobile signal. More specifically, when the input +x axis moves the signal and then the keystroke signal is input, the next music is selected, and in the case where the -x axis moves the signal and then the keystroke signal is input, the previous one is selected. music. In the case where it is decided that there is no keystroke signal, a fast-forwarding or rewinding function (S180) is performed based on the direction information of the mobile signal. More specifically, if only the +x axis movement signal is applied, the fast forward function is performed, and if only the -x axis movement signal is applied, the rewind function is performed.

In the above-described embodiments, an electronic device including an input unit, a main body unit, and a display unit has been described. In other embodiments, portions of the input unit and portions of the body unit may be combined to form an indicator device for controlling the indicators on the screen. That is, some portions of the input unit and portions of the main unit can be provided in the form of an integrated module.

Further, in the above-described embodiment, the index control module can be provided in the form of a program included in the control wafer (integral wafer) of the main unit or stored in the recording medium. Of course, the indicator control module can be provided in the form of a program recorded in the indicator control unit. Here, the program stored in the recording medium is computer readable.

As shown in the above embodiment, the index control module generates various input control signals and uses the mobile signal generated in response to the movement of the actuating member and the keystroke signal generated when the actuating member presses the dome switch. By using the input control signal, the indicator control module controls the operation of the program. Therefore, the number of dome switches required for the operation of the control program is reduced.

However, the invention is not limited thereto. The index control module can move the indicators on the screen by using mobile signals generated in response to movement of the actuating member. That is to say, according to the mode selection signal applied to the indicator control module, the indicator (mouse or cursor) can be located on the screen, and the program can be executed and controlled by using the indicator to key the dome switch. As described above, by moving the actuating member, the magnet portion, and the intermediate member, the indicator on the screen can be moved to an ideal position in the x-axis or the y-axis, so that the index can be placed on the indicator to control the executed. In the area of the program. Next, the dome switch can be pressed to perform the function of the program corresponding to the current position of the indicator.

The present invention is not limited to the above embodiments, and according to the present invention, the operations of various programs can be controlled by various methods. In the following description, a control method of an operation of an image control and management program according to other exemplary embodiments will be described in detail with reference to the accompanying drawings.

In the following description of the current embodiment, the same description as the above embodiment will not be repeated. The technology of the present embodiment can be applied to the above-described embodiments, and the techniques of the above embodiments can also be applied to the current embodiment.

FIG. 8 is a front view of an electronic device in accordance with another exemplary embodiment of the present invention.

Referring to FIG. 8, the electronic device of this embodiment includes: a display unit 3000 configured to display a pointer and an image; and an input unit 1000 configured to generate a sensing signal according to a user operation and other signals; The main body unit 2000 is configured to execute or control a program according to the sensing signal, and output a signal to the display unit 3000 to display the image on the display unit 3000.

The index control unit 1100 includes a substrate 1110, a magnet portion 1120, an actuation member 1130, an intermediate member 1140, a sensor portion 1160, and a cover portion 1150. The main unit 2000 includes an indicator control module 2100, a memory 2200, a drive control module 2300, an audio/video control module 2400, and a wired/wireless communication control module 2500. The display unit 3000 is configured to display an image on a screen by using an image signal received from the main unit 2000. That is, the program executed (activated) by the main body unit 2000 is displayed on the display unit 3000. In FIG. 8, a map search (or image editor) program is displayed on the screen of the display unit 3000. Based on the indicator movement control signal received from the body unit 2000, the display unit 3000 can display the indicator on the screen and move the indicator on the screen.

Since the same components have been described in the description of the above embodiments, the input unit 1000, the display unit 3000, and the main body unit 2000 will not be described in detail.

In the following description, based on the operation of the indicator control module 2100 and the indicator control unit 1100 configured to generate a sensing signal and/or a keystroke signal, a control program for controlling an image (eg, a map or a photo) will be described. method. The following description is an operation performed after the image of the map is downloaded onto the display unit 3000. The image can be downloaded to the display unit 3000 in response to the signal (sensing signal, keystroke signal) output from the indicator control unit 1100.

9 is a flow chart of the operation of an image control program in accordance with an exemplary embodiment of the present invention.

Referring to FIG. 9, the operation mode is selected (S1100) by deciding whether to input a keystroke signal or a double-click signal. Select the movement mode or the enlargement/reduction mode according to the keystroke signal or the double-click signal. In addition, you can select the menu generation mode.

If no keystroke signal or double-click signal is entered, select the move mode. In the moving mode, the map (image) is moved up, down, left or right on the screen according to the sensing signal generated in response to the movement of the actuating member 1130 (S1110). At this time, the index control module 2100 generates a motion control signal according to the moving direction information included in the sensing signal. Then, according to the motion control signal, the map is moved to the display unit 3000.

At this time, the actuating member 1130 moves on a two-dimensional plane (±x axis and ±y axis).

If the range of movement of the actuating member 1130 is divided into four regions (+x region, -x region, +y region, and -y region), four motion control signals can be generated. That is, according to the movement of the actuation member 1130, the index control unit 1100 outputs a +x axis sensing signal, an -x axis sensing signal, a +y axis sensing signal, and a -y axis sensing signal. In response to the sensing signal, the indicator control module 2100 generates a right motion control signal, a left motion control signal, an uplink motion control signal, or a lower motion control signal. Next, move the map to the right, left, up, or down. By the line between the x-axis and the y-axis (the line is 45 degrees from the x-axis), four regions can be determined.

However, the invention is not limited thereto. For example, the moving range of the actuating member 1130 is divided into eight regions (+x region, +x+y region, +y region, -x+y region, -xy region, -y region, and -y+x region). . In this case, the map can be moved to the right in the screen, moving in the upper right direction, moving in the upward direction, moving in the upper left direction, moving in the left direction, moving in the lower left direction, moving in the downward direction, and moving in the lower right direction. mobile. However, the invention is not limited thereto. The range of movement of the actuation member 1130 can be split into more or fewer regions. Alternatively, depending on the movement of the actuating member 1130, the map can be moved directly on the screen instead of splitting the range of motion. In this case, the change in the sensing signal output in response to the movement of the actuating member 1130 can be directly converted into a motion control signal.

Additionally, the actuation member 1130 can be rotated clockwise or counterclockwise. In this case, the indicator control module 2100 can generate a motion control signal corresponding to the rotation of the actuation member 1130.

As described above, after the movement of the actuating member 1130 is performed to move the map on the screen, it is determined whether or not a keystroke signal is applied.

If a keystroke signal is applied, the zoom in/out mode is selected. In the enlargement/reduction mode, the map of the screen is enlarged or reduced according to the sensing signal generated in response to the movement of the actuation member 1130 (S1120).

In this embodiment, the indicator control module 2100 divides the sensing signal output from the indicator control unit 1100 into two signal groups, and then the indicator control module 2100 generates an amplified motion control signal according to the signal group. And a reduced mobile control signal. This means that the range of movement of the actuating member 1130 is divided into two regions.

For example, if the range of movement of the actuation member 1130 is divided into an upper region and a lower region according to the x-axis, the sensing signal generated when the actuation member 1130 is located in the upper region is converted into an enlargement of the map for amplifying the screen. Mobile control signal. On the other hand, the sensing signal generated when the actuation member 1130 is in the lower region is converted into a reduced motion control signal that reduces the scale of the map of the screen. In this case, the zoom-in or zoom-out function is performed using a predetermined magnification ratio. However, the invention is not limited thereto. For example, as described above, the range of movement of the actuation member 1130 can be divided into a plurality of regions, and different magnification ratios can be configured for each region. Alternatively, the sensing signals generated by the clockwise rotation and the counterclockwise rotation of the actuation member 1130 can be converted into a motion control signal for amplification and a motion control signal for reduction, respectively. In this case, whether or not the actuation member 1130 is rotated can be determined by the sensing signal input to the indicator control module 2100 during each signal input. More specifically, for example, if the sensing signals input to the index control module 2100 are different during no more than 2 to 5 signal input periods, it is determined that the actuation member has been rotated, and corresponding movement control is generated. Signal.

In the case where a keystroke signal is applied, the position of the indicator (mouse indicator) located on the map may be the center position of the screen.

After the scale of the map of the screen is enlarged or reduced, it is determined whether a keystroke signal or a double-click signal is applied (S1130). If a keystroke signal or a double-click signal is not applied, the enlargement/reduction operation is repeated. If a keystroke signal or a double-click signal is applied, the zoom in/out mode is ended. That is to say, the operation mode is changed to the movement mode. If a double-click signal is applied, the menu for zoom in/out mode is displayed.

If a double-click signal is applied during the operation mode selection operation or in the enlargement/reduction mode, the menu generation mode is executed. This will be described in detail below.

Respond to the double-click signal to execute the menu generation mode. In the menu generation mode, various popup menus (S1140) for controlling the map of the screen are displayed.

Then, one of the plurality of pop-up menus can be started according to the sensing signal (S1150). More specifically, if the user moves the actuating member 1130 to the left, right, up, or down, a sensing signal is generated in response to the user's operation. Next, the indicator control module 2100 generates a motion control signal in response to the sensing signal, and moves the activation area to the left, right, up, or down according to the motion control signal, thereby starting the ideal menu. Thereby, it is determined whether or not a keystroke signal is applied (S1160). If a keystroke signal is applied, an operation corresponding to the activated menu is executed, and the menu generation mode is ended (S1170). On the other hand, if a keystroke signal is not applied, the menu generation mode is ended without performing an operation corresponding to the activated menu. At this time, it is determined whether to apply a keystroke signal for a period of no more than 2 to 200 signal input. That is to say, if no keystroke signal is applied during no more than 2 to 200 signal input, the menu generation mode is ended. That is, the operation mode is changed from the menu generation mode to the mobile mode.

Examples of menus include map menus such as editor stop, mode change, zoom in, zoom out, search, start and destination assignments, distance calculations, and indicator fixation; image editing menus; and navigation menus.

As described above, according to the present embodiment, the operation mode can be selected in different manners according to the keystroke signal or the double-click signal, and the ideal image control operation can be performed according to the sensing signal in the selected operation mode. In this manner, by using a dome switch, a magnet, and a sensor configured to output a signal according to a change in the magnetic field of the magnet, it is possible to perform an image (for example, a photograph, a map, and a map). Various control operations like picture. Therefore, the size of the input unit and the number of dome switches required can be reduced.

In addition, according to the embodiment, various motion control signals can be generated by using a keystroke signal, a double-click signal, and x-axis and y-axis sensing signals (mobile signals).

For example, a motion control signal can be generated according to the keystroke signal; four motion control signals can be generated according to the ±x axis and the ±y axis sensing signal; and the motion control signal can be generated according to the double keystroke signal. Further, two movement control signals can be generated according to the clockwise and counterclockwise rotation of the actuation member 1130 of the index control unit 1100. However, the invention is not limited thereto. For example, more motion control signals can be generated based on various combinations of keystroke signals, double-click signals, ±x-axis sensing signals, and ±y-axis sensing signals, as well as rotating signals.

As described above, according to the motion control signal generated in response to the keystroke signal or the double-click signal, the operation mode can be selected, and then according to the next motion control signal, the desired operation can be performed in the selected operation mode.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
