Description of the Invention: [Technical Field] The present invention relates to an analog navigation method for a navigation device, and more particularly to an interactive analog navigation method for a navigation device. [Prior Art] The existing navigation device provides an analog navigation mode for the user to select in order to provide a more convenient navigation path preview function for the user. In the simulated navigation mode, after the navigation device receives the start and destination of the user input, the analog navigation screen is directly played. The simulated navigation screen displays an icon representing the user's vehicle, and the icon moves at a specific speed on the planned path; the visual month 'J some navigation system is also used to adjust the moving speed of the icon on the planned path. . For users who are not familiar with the path, the navigation function of the navigation device allows the user to know the driving path at the intersection in advance to ensure safe driving. However, the existing analog navigation mechanism is monotonous, and the user only passively watches the analog navigation surface. It is easy to ignore or miss the turn of some intersections or switch the lanes. Therefore, the existing analog navigation mode has limited help to the user. [Invention] Therefore, an object of the present invention is to provide an interactive analog navigation method for allowing a user to lean forward, backward, left, or The right tilt controls the movement of the icon representing the vehicle in the simulated navigation screen, thereby allowing the user to simulate the navigation path to ensure driving safety. The interactive analog navigation method of the present invention is implemented by using a navigation device 201245667, which has a sensing unit for sensing the motion state of the navigation device itself to generate a motion information, and the interactive analog navigation method includes The following steps: (a) Start a simulated navigation mode to display a simulated navigation screen with a navigation path and an icon representing the vehicle. (b) receiving motion information output by the sensing unit. (c) generating a rotation value representative of the rotation of the navigation device about an axis based on the motion information conversion. (d) determining whether the rotation value exceeds a preset value, if so, causing the icon to move in the simulated navigation screen in a predetermined direction associated with the rotation value. The foregoing axis may be a single finger that vertically passes through the axis of the display screen of the navigation device; and the step (d) determines that the rotation value exceeds a positive preset value, the preset direction refers to the right; when it is determined that the rotation value is exceeded A negative preset value, which refers to the left. Of course, the present invention can also receive the motion information of the sensing unit output above two axes. Therefore, step (c) may be based on the motion information conversion to generate a first rotation value representing the navigation device itself rotating about a first axis, and generating a second rotation value representing the navigation device itself rotating about a second axis. . For example, the first axis refers to an axis that vertically passes through the display screen of the navigation device, and the second axis refers to an axis that passes transversely through the navigation device and is perpendicular to the first axis; the step (d) is Determining that the first rotation value exceeds a positive preset value, the preset direction means pointing to the right, when determining that the first rotation value exceeds a negative preset value, the preset direction means pointing to the left; No. 201245667 The second rotation value exceeds a positive preset value, which refers to the forward direction. When the judgment exceeds a negative preset value, the preset direction refers to the backward direction. The sensing unit may include only a gyroscope, and the motion information is an angular velocity value; and the step (c) integrates the angular velocity value to obtain an angle representing the navigation device itself rotating about the axis. The sensing unit may also include only a gravity sensor, the motion is a gravitational acceleration value; and the step (c) converts the gravitational acceleration value by a dihedral function to obtain an angle representing the navigation device itself rotating about the axis. . Of course, the aforementioned sensing unit may also include a gyroscope and a gravity sensor. In step (d), it may be further determined in detail whether the rotation value exceeds a first preset value; if not, the state of the icon is not changed, and if yes, it is determined whether the rotation value exceeds a first preset a second preset value of the value; if not, causing the icon to move toward the predetermined direction in the simulated navigation screen at a first speed, and if so, causing the icon to be at a second speed that exceeds the first speed The simulated navigation screen moves toward the preset direction. Further, the simulated navigation mode of the step (a) is to advance the icon on the navigation path at a predetermined speed; if the rotation value exceeds the first preset value or the second pre-determination in the step (d) a value is set, the icon is accelerated or deviated from the navigation path at the first speed or the second speed in the simulated navigation screen, and the first speed or the second speed is greater than the predetermined speed. In step (d), it may also be determined whether the rotation value is maintained beyond 201245667. The preset value reaches - preset time'. If so, the icon is moved in the preset direction in the simulated navigation screen. Further, the simulated navigation mode of the step (1) is to advance the icon on the navigation path at a predetermined speed; if it is determined in the step that the rotation value exceeds the preset value for the preset time, the icon is spoken加速 The simulated navigation screen accelerates or deviates from the navigation path toward the preset direction. Further, the interactive analog navigation method of the present invention further comprises a step (e) determining whether the icon is on the navigation path, and if not, re-planning the path and returning to the display simulation navigation screen of step (a), and continuing to execute Steps (b) to (4). It is still another object of the present invention to provide a computer program product which, when loaded into a computer program product by a navigation device, can perform the aforementioned interactive analog navigation method. Another object of the present invention is to provide a navigation device that allows a user to control the movement of an icon representing a vehicle in a simulated navigation screen by actually operating the navigation device to tilt forward, backward, left, or right, thereby allowing the user to simulate driving navigation. Path to ensure safe driving. The navigation device comprises an analog navigation unit, a display screen, a sensing unit and a processing unit. An analog navigation unit receives an initial location information and a destination information, and performs path planning to generate a simulated navigation screen. The simulated navigation screen does not have a navigation path and an icon representing the vehicle. The display shows the simulated navigation screen. The sensing unit senses the motion state of the navigation device itself to generate a motion information. The processing unit generates a 201245667 representing the rotation value of the navigation device itself rotating around an axis according to the motion information conversion and determining whether the rotation value exceeds a preset value. If yes, the icon is displayed in the simulated navigation screen. The preset direction of the rotation value is moved. The effect of the present invention is to enable the user to use the forward tilting, backward tilting, left tilting or right tilting navigation device after the planning path to accelerate or deviate the icon in the simulated navigation surface to provide a new experience for the user. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figure 1, a first preferred embodiment of the navigation device 100 of the present invention includes an analog navigation unit 1, a display screen 2, a sensing unit 4, and a processing unit tl 3. The sensing unit 4 of the embodiment includes a gyroscope 41. The processing unit 3 has a built-in timer 31. Referring to Fig. 2', when the navigation device ι is operated to initiate a simulated navigation mode, the interactive analog navigation method of the present invention is executed, and the method includes the following steps. Step SU - The analog navigation unit 1 receives the start-to-start information and a destination information input by the user. Step S12 - Simulating the navigation unit 丨 starting to perform path planning. Step S13 - The analog navigation unit 1 generates - the simulated navigation screen 1G as shown in Fig. 3, and causes the display screen 2 to display it. In the simulated navigation screen 10, 201245667 does not have a navigation path 51 and an icon 52 representing the vehicle. The icon 52 advances on the navigation path 51 at a predetermined speed from the start in the simulated navigation screen 10, thereby allowing the user to view and understand the navigation path 51. In addition, since the present invention provides an interactive analog navigation method, the initial motion state of the icon 52 is not limited to the foregoing, and may also be designed such that the start icon 52 is located at the beginning of the navigation path 51 and is stationary, completely used. The user controls the icon 52 to move the state. This embodiment exemplifies only the mode in which the icon 52 advances at the navigation path 51 at a predetermined speed. The user can actually move the navigation device 1 forward, backward, left, or right. The icon 52 in the simulated navigation screen accelerates or deviates from the navigation path 51; thereby, the simulated navigation of the navigation device 100 is no longer simply playing the simulated navigation screen, but the user is allowed to manipulate the icon 52 in an interactive manner before the actual departure. Simulated driving. Step S21 - When the user operates the navigation device i, the navigation device 1 is tilted forward and backward about a first axis A1, or tilted left or right around a second axis A2, the gyroscope of the sensing unit 4 41 will output a signal representing an angular velocity value for the motion state around each of the axes A1, A2, and the processing unit 3 will receive the signal to obtain the angular velocity value. The aforementioned first axis A1 refers to an axis that passes through the screen 2 of the navigation device 100 vertically, and the second axis A2 refers to an axis that passes through the navigation device 100 and is perpendicular to the first axis A1. Step S22 - The processing unit 3 integrates each of the angular velocity values to obtain an angle representing that the navigation device 100 itself rotates about the corresponding axis. Referring to Fig. 4, the broken line 61 represents the angular velocity value output by the gyro 41, and the broken line 62 represents the angle after the integration of the processing unit 3, hereinafter referred to as the rotational value. 201245667 - Pre-3 judges whether the rotation value continues to exceed - the gate time, the first preset value such as coffee. If it is preset, then step s24 is performed; if not, it is regarded as a flat step S24 - the processing unit 3 continues to determine whether the rotation value is maintained beyond a second preset value for a preset time, the second preset The value is for example +6(). ; if no, the representative rotation value is between +30. ~+60. Between, or between _3〇. ~_6〇. If the door is the step, if the step is 'representing the rotation value exceeds ±6〇 S26. Step S25 - causing the icon 52 to move 1 in the simulated navigation plane 1 to a predetermined direction associated with the rotation value at a _ speed greater than a predetermined speed at which the icon 52 is originally advanced on the navigation path 51. Step S26 - causing the icon 52 to move in the preset direction in the simulated navigation screen 1 以 at a second speed greater than the first speed. In detail, with respect to steps S25 and S26, when the rotation value is generated around the first axis Ai and is between +30. ~+6〇. Between the two, the preset direction means to the right; when the rotation value is generated around the first axis A1 and is between _3 〇. ...6〇. Between, then the preset direction means to the left. When the rotation value is generated around the second axis A2 and is between +30 and +60. Between, then the preset direction means forward: when the rotation value is generated around the second axis A2 and is between _3 〇. ~_6〇. Between 'the default direction means backwards. Thereby, the icon 52 in the simulated navigation plane 1 is not only advanced on the navigation path 51 according to the predetermined speed, and the user can control the navigation device 1 to change the motion state of the icon 52 to make it turn left, turn right or Go forward and back. 201245667 Step S31 - Next, the processing unit 3 also determines whether the icon 52 is on the navigation path 51. If yes, go to step S41; if no, it means to simulate the line. The driving has deviated from the navigation path 5, just like the actual driving error recognition command and leave the navigation path. At this time, the simulated navigation unit performs step S32 to re-plan the path. Then, it returns to step S13. The user can know in advance that the navigation system 100 reacts when the navigation system 100 is actually used in a certain section without following the planned route. Step S41 - Finally, it is determined whether the circle 52 reaches the destination in the simulated navigation screen 10. If yes, the simulated navigation mode is ended; if not, the process returns to step S21 to continuously receive the motion information. Referring to FIG. 5 and FIG. 6, the difference between the second preferred embodiment of the present invention and the first preferred embodiment is that the sensing unit 4 includes a gravity sensor 42. Therefore, in terms of the flow of execution, the first preferred Step S2 of the embodiment and the steps S21' and S22' are not changed. Therefore, the following steps are only described in detail for steps S21' and S22', and the unmodified flow will not be described again. Step S21' The gravity sensor 42 of the sensing unit 4 outputs a signal representing a gravity acceleration value for the motion state of each axis A1, A2, and the processing unit 3 receives the signal to obtain the gravity acceleration value. Step S22' The processing unit 3 converts each of the gravitational acceleration values by a trigonometric function to obtain an angle representing that the navigation device 1 itself rotates about the corresponding axis. Referring to the circle 6, the movement state of the navigation device 100 rotating about the first axis A1, for example, the signal outputted by the gravity sensor 42 when the 'flat-flat' is 〇g, g = 9.8 m/s2 . When the navigation device 1 lingers

Using the two-angle function, the following relationship can be known, sin(0°)=0; sin(30°)=0.5; sin(90°)=i. Therefore, when the navigation device 100 is rotated +30° about the first axis A1, it represents a right tilt of 3 〇. Conversely, rotating -30° around the first axis means 30° left. It is worth mentioning that 'the invention is implemented, and the motion information output by the gyroscope 41 and the gravity sensor 42 can be simultaneously used, and the conversion is performed. After the rotation value is output, the two are mutually corrected or calculated as an average value, and the subsequent steps are performed, thereby improving the stability. In summary, the navigation device 100 and the interactive analog navigation method of the present invention utilize the gyroscope 41 or the gravity sensor 42 to sense the user's operation behavior, and the user can thereby control the navigation device to lean forward and backward, The leftward or rightward tilt controls the motion state of the icon 52 representing the vehicle in the simulated navigation screen 1 to achieve an interactive effect, thereby allowing the user to simulate the driving navigation path to ensure driving safety, and thus the object of the present invention can be achieved. However, the above is only a preferred embodiment of the present invention, and Sb is not intended to limit the scope of the present invention, that is, simple equivalent changes and modifications made in accordance with the scope of the present invention and the description of the invention. All remain within the scope of the invention patent.
