FIG. 3 is a schematic diagram illustrating a method for detecting abnormal mouse behavior according to an embodiment of the present invention.

In step 210 , the mouse movement detection device 30 is used to detect a physical movement state of a mouse 40 .

In one embodiment, the mouse motion detection device 30 includes a mouse pad and a plurality of infrared devices. In the example of FIG. 3, each circle arranged laterally along the X-axis represents an infrared device PX (for example, an infrared device PX). Each circle represents a laser diode PX), and each circle arranged longitudinally along the Y axis represents an infrared device PY (for example, each circle represents a laser diode PY), so these infrared devices PX and The PYs are arranged in an L shape and are disposed on the mouse pad 30 .

Taking FIG. 3 as an example, the mouse 40 moves from point A to point B, and the infrared devices PX and PY use time-of-flight ranging technology to detect a physical position of a starting point and a physical position of a stopping point of the mouse 40 moving.

The physical position of the starting point includes an X-axis physical starting position and a Y-axis physical starting position. For example, the infrared rays of the infrared device PX1 hit the mouse 40 located at point A, and receive the reflected infrared rays, whereby the distance X1 between the mouse 40 located at point A and the X-axis can be calculated according to the round-trip time of the infrared rays and the infrared beam. ' is 3 centimeters (cm), and this value can be regarded as the physical starting position of the Y-axis of the mouse 40. On the other hand, the infrared rays of the infrared device PY1 hit the mouse 40 at point A, and receive the reflected infrared rays, According to the infrared round-trip time and the infrared beam, the distance Y1' between the mouse 40 at point A and the Y-axis can be calculated to be 2.5 centimeters (cm), which can be regarded as the physical starting position of the mouse 40 on the X-axis.

The physical position of the stop point includes an X-axis physical stop position and a Y-axis physical stop position. For example, the infrared rays of the infrared device PX2 hit the mouse 40 at point B, and receive the reflected infrared rays, so that the distance X2 between the mouse 40 at point B and the X-axis can be calculated according to the round-trip time of the infrared rays and the infrared beam. ' is 4.5 centimeters (cm), and this value can be regarded as the physical stop position of the Y-axis of the mouse 40. On the other hand, the infrared rays of the infrared device PY2 hit the mouse 40 at point B, and receive the reflected infrared rays. According to the infrared round-trip time and the infrared beam, the distance Y2' between the mouse 40 at point B and the Y-axis can be calculated to be 6.5 centimeters (cm), which can be regarded as the X-axis physical stop position of the mouse 40 .

The processor 14 obtains a Y-axis physical moving distance of 1.5 after subtracting the Y-axis physical starting position 3 from the Y-axis physical stop position 4.5, and subtracting the X-axis physical starting position 2.5 from the X-axis physical stopping position 6.5, Obtain an X-axis physical movement distance 4, divide the Y-axis physical movement distance 1.5 by the X-axis physical movement distance 4, obtain a physical movement slope 0.375, and inverse the physical movement slope 0.375 After the trigonometric function tan ^-1 , get a physical movement The angle is about 20.556 degrees, and this physical movement angle is regarded as a physical movement state.

In step 220 , the mouse movement event receiver 10 is used for receiving a movement event of the mouse 40 .

In one embodiment, the mouse movement event receiver 10 receives two mouse signals for the mouse 40 to move from a starting coordinate A to a stopping coordinate B; wherein the starting coordinate A includes a starting point X-axis coordinate and a starting point The Y-axis coordinate (for example, the coordinate of point A is represented by A(X1, Y1), for the convenience of description, it is assumed that X1 is 11 and Y1 is 15), the stop point coordinate B includes a stop point X-axis coordinate and a stop point Y-axis coordinate ( For example, the coordinates of point B are represented by B(X2, Y2). For the convenience of description, it is assumed that Y1 is 29 and Y2 is 22). The processor 14 subtracts the Y-axis coordinate 15 of the starting point from the Y-axis coordinate 22 of the stopping point to obtain a Y-axis moving coordinate 7, and subtracts the X-axis coordinate 11 of the starting point from the X-axis coordinate 29 of the stopping point to obtain an X-axis coordinate. Axis moving coordinate 18, divide the Y-axis moving coordinate 7 by the X-axis moving coordinate 18, and obtain a receiving moving slope of 0.389. After inverting the receiving moving slope with the trigonometric function tan ^-1 , a receiving moving angle of about 21.256 degrees is obtained. Movement angles are considered movement events.

In step 230, the processor 14 compares whether the physical movement state is consistent with the movement event. When the processor 14 compares the physical movement state with the movement event, it proceeds to step 240 . When the processor 14 compares the physical movement state and the movement event to be inconsistent, it proceeds to step 250 .

In step 240, the processor 14 outputs a normal reporting signal.

In one embodiment, when the processor 14 compares the physical movement state with the movement event, the processor 14 displays a mouse signal on a display 20 .

In one embodiment, when the difference between the physical movement angle and the received movement angle compared by the processor 14 is less than an angle difference range (eg, plus or minus 2 degrees), the processor 14 considers that the physical movement state is consistent with the movement event, and outputs a normal state. Signal point.

In the foregoing example, the physical moving angle is about 20.556 degrees, and the receiving moving angle is about 21.256 degrees. If the preset angle difference range is plus or minus 2 degrees, the difference between the two angles falls within the angle difference range, so the processor 14 determines the physical The movement state is consistent with the movement event, and a normal alarm signal is output.

In step 250, the processor 14 outputs an abnormal signal.

In one embodiment, when the processor 14 determines that the physical movement state is inconsistent with the movement event, the reported point of the mouse 40 may be wrong, so the processor 14 filters out the reported point of the mouse movement.

In one embodiment, when the processor 14 compares the difference between the physical movement angle and the received movement angle is not less than an angle difference range (eg, plus or minus 2 percent), the processor 14 considers that the physical movement state is inconsistent with the movement event, Output abnormal signal.

In one embodiment, when the processor 14 executes an application program, the application program is a game software, and the mouse 40 is used to control a virtual object in the game software. When the processor 14 determines that the mouse movement detection device 30 does not have a first distance 54 , d detects a physical movement state, but the mouse movement event receiver 10 receives a movement event, the processor 14 determines the physical movement state and the virtual object The movement events are inconsistent, and an abnormal signal is output. The abnormal signal is used to indicate that a cheating event occurs (for example, an e-sports player presses the shortcut key/hot key button on the mouse 40, so the virtual character can move quickly without moving the mouse 40) Or a point error event (such as noise interference or signal drift resulting in point error).

In one embodiment, when the processor 14 executes an application program, the application program is a game software, and the mouse 40 is used to control a virtual object in the game software. When the processor 14 determines that the physical movement state is inconsistent with the movement event of the virtual object, for example, assuming that the general mouse is dragged down by 3 cm (physical movement state), the virtual character in the game takes a step back (the movement event of the virtual object). , but the processor 14 determines that the mouse 40 is only dragged down by 0.5 cm (physical movement state), and the character in the game takes a step back (the virtual object movement event), then the processor 14 outputs an abnormal signal, which is used to indicate that the occurrence of A cheating event or a reporting error event.

In one embodiment, when the processor 14 executes an application program, the application program is a game software, and the mouse 40 is used to control a virtual object in the game software. When the processor 14 determines that the mouse movement detection device has a first distance 54, d 30 detects a physical movement state, but the mouse movement event receiver 10 does not receive a movement event, the processor 14 outputs an abnormal signal, and the abnormal signal uses To indicate the occurrence of a noise interference event, a mouse failure event or a mouse movement event receiver damage event.
