Therefore, the electronic device of the present embodiment determines the user's manipulation to move the pointer on the screen. That is, a plurality of sensing signals sequentially output from the pointing control means 1100 according to a user's operation are provided to the pointer control module 2100 of the main body 2000, and the pointer control module 2100 sequentially provides the sensing signals. It is determined whether the user's manipulation changes rapidly or slowly, or stays at the maximum or minimum value, and provides the display unit 3000 with a pointer movement control signal weighted accordingly. As a result, the pointer 100 in the display unit 3000 is moved.

- the pointer control module 2100 outputs a corresponding pointer movement ⁇ signal by assigning a weight corresponding to each defined section.
- a method of moving the pointer 100 will be described based on the operation of the pointer control module 2100.
- the magnitude of the sensing signal level is limited within a certain range. This is because the movement of the magnet part 1120 is limited by the area between the cover part 1150 and the operation member 1130 (ie, K area of FIG. 3).
- the output level of the sensing signal due to the movement of the magnet unit 1120 is divided into a plurality of sections along the movement axes (X axis and Y axis). This is because three sensors are located on the X-axis and the Y-axis, respectively, and sense the movement of the magnet unit 1120 by using a change in their output values. Accordingly, as shown in FIG. 5, the sensing unit 1100 is divided into 16 sensing signal sections according to the movement in one axis of the magnet unit 1120 (that is, the output level of the sensing signal). The sensing signal output through the video is divided into 16 parts.
- the movement of the magnet unit 1120 and the output level of the sensing signal are proportional to 0 and 8 sections (reference point sections). Of course, the section is not limited thereto, and may be divided into more or less sections.

The pointer control module 2100 also outputs a pointer movement control signal whose output level increases sequentially.
- the output of the pointer movement control signal is reduced.
- the output level of the pointer movement control signal and the movement of the pointer 100 are proportional. That is, when the output level of the pointer movement control signal increases, the movement of the pointer 100 becomes faster. On the other hand, when the output level of the pointer movement control signal decreases, the movement of the pointer 100 becomes slow. This change in movement is effective to change relatively.

As a result of the comparison, it is again determined whether the difference between the signal intervals is greater than two (S120).
- the interval difference comparison means that the difference between the sections described above with reference to FIG. 5 occurs two or more steps. Therefore, when the zero sensing signal is output as the previous sensing signal, the third sensing signal is output as the current sensing signal, the interval difference is 3, and the zero sensing signal is output as the previous sensing signal, and the first sensing signal is as the current sensing signal. When the signal is output, the interval difference is 1.
- the pointer movement control signal to which the weight corresponding to the current sensing signal is assigned is generated according to the first variable lookup table (S130).
- the pointer 100 in the display unit 3000 is moved using a pointing movement control signal weighted according to the first variable lookup table (S140). At this time, even if the user moves the operating member 1130 abruptly by the first variable lookup table, only the pointing movement control signal having the maximum weight value 3 is output.
- the pointer 100 within the screen may be gradually moved. That is, the movement of the pointer 100 may be smoothly maintained by preventing the sudden movement of the pointer 100 at the time when the pointer 100 is stopped for the first time by the user's pointing control means 1100.

- the pointer 100 in the display unit 3000 is moved using a pointing movement control signal weighted according to the second variable lookup table (S160).
- the weight of the pointing movement control signal corresponding to the current sensing signal is zero. This means that the pointer 100 in the screen does not move.
- the interval difference is defined as 2, but the present invention is not limited thereto and may be designated as 3 or 4. In this case, when the interval difference is 5 or more, a problem may occur in which the user cannot cope with fine adjustment or rapid change of the pointer.

- K which is the maximum value duration number
- N the set N value
- K ⁇ N the K value
- a pointer movement control signal with a weight corresponding to the current sensing signal is generated according to the reference lookup table (S230). That is, since the current sensing signal has the maximum value, the pointer movement control signal has a weight of seven. In this case, not only the reference lookup table but also the second and third variable lookup tables may be used.

- the weight value amplified by a value corresponding to the K value may be at least 10% and up to 100% with respect to the current weight value. And, it is desirable to increase within the range of 5 to 10% as the K value increases. That is, the weight of the current sensing signal by the reference lookup table is 7. For example, if the value of K increases from 3 to 12, the weight of the pointer movement control signal is 7.1 when the K value is 3, 8.4 when the K value is 4, and 14 when the K value is 12. Can be.

- the continuous movement mode first determines whether the sensing signal is increased or decreased (S310). That is, whether the magnet unit 1120 moves from the center point to the maximum movement distance region (ie, increased from the zeroth sensing signal to the seventh sensing signal) or moves from the maximum movement distance region to the center point region (that is, the seventh Reduced from the sensing signal to the zeroth sensing signal). As a result of the determination, if it is increased, a pointer movement control signal with a weight corresponding to the current sensing signal is generated according to the third variable lookup table (S320). Subsequently, the pointer 100 in the display unit 3000 is moved using a pointing movement control signal weighted according to the third variable lookup table (S330), and the mode ends.
- the weight of the pointer movement control signal for controlling the movement speed of the pointer 100 on the screen through the third variable lookup table is given, so that the pointer 100 on the screen is fast while the magnet unit 1120 is moved by the user. You can make a response.
