Is being used. The navigation device receives radio waves representing latitude, longitude, altitude, etc. from a plurality of satellites, calculates the current position of the vehicle, and then outputs map information including the current position to the driver.

In addition, the navigation device provides the user with various information necessary for driving, such as outputting the driving direction of the vehicle, the distance to the destination, the current moving speed of the vehicle, and the like. Moreover, the navigation device receives the predetermined data from the GPS satellite floating on the earth using the receiver, and calculates its position based on the received data.

Will be able to calculate their position. Therefore, the navigation device provides various driving information to a transportation device such as the vehicle based on its position information (latitude and longitude information) calculated in this way.

In the past, the navigation device was mainly used for calculating and navigating the position of a large moving object such as an aircraft or a ship. In addition, the navigation device provides the user with a wide variety of information, such as the current location of the transport device, route information from the current location of the transport device to the destination, map information related to the location information and road information, and traffic condition information.

In detail, the navigation device obtains the driving trajectory of the vehicle by using the orientation sensor and the distance sensor mounted on the vehicle to obtain the current position of the vehicle, and then compares the driving trajectory of the vehicle with the road shape on the digital numerical map and determines the passing road. It is a system that maps the location of the vehicle on the digital numerical map and outputs the location of the map-matched vehicle on a screen such as a monitor.

However, in the above-described prior art, the navigation apparatus has the following problems.

That is, when the optical signal output from the light emitting unit 21 of the optical sensor is reflected from the operating object and received by the light receiving unit 23 of the optical sensor, it may be determined whether the movement of the operating object is detected. On the other hand, the sensing area, it can be understood that the optical signal of the optical sensor represents the recognition distance for detecting the operation object.

In addition, when the movement of the operation object is not detected, the optical sensor maintains a standby state, and when the movement of the operation object is detected, an initial input is detected by the operation processor 25 (S120).

In addition, when the initial input is detected, it is determined whether the motion is detected through the entry of the operating object in the sensing area of the optical sensor other than the optical sensor in which the initial input is detected (S130).

Here, when the movement of the operating object is not detected in the sensing area of the optical sensor other than the optical sensor in which the initial input is detected within a predetermined time from the time of the initial input, the data of the plurality of optical sensors is initialized to the standby state. Becomes When the motion of the operating object is detected in the sensing region of the optical sensor other than the optical sensor in which the initial input is detected within a predetermined time from the time of the initial input, the late processing input is detected by the operation processor 25. (S140).

Meanwhile, another embodiment of an operation method using an optical sensor of a navigation device according to the present invention will be described with reference to FIGS. 1 and 4.

4 is a flowchart illustrating an operation method using an optical sensor of a navigation device according to another embodiment of the present invention.

As shown in FIG. 1 and FIG. 4, when the power of the navigation device 10 is connected, data of a plurality of optical sensors, each of which is assigned a unique mark arranged outside the display unit 13, is initialized to a standby state. (s200).

In operation S210, it is determined whether the motion is detected through the entry of the operating object into the sensing area of the optical sensor. That is, when the optical signal output from the light emitting unit 21 of the optical sensor is reflected from the operating object and received by the light receiving unit 23 of the optical sensor, it may be determined whether the movement of the operating object is detected.

In addition, when the movement of the operation object is not detected, the optical sensor maintains a standby state, and when the movement of the operation object is detected, the initial input is detected by the operation processor 25 (S220).

In addition, when the initial input is detected, it is determined whether the motion is detected through the entry of the operating object in the sensing area of the optical sensor other than the optical sensor in which the initial input is detected (S230).

Here, when the movement of the operating object is not detected in the sensing area of the optical sensor other than the optical sensor in which the initial input is detected within a predetermined time from the time of the initial input, the operation data matching only the initial input is detected. In operation S240, the function of the matched operation data is performed in operation S250.

In detail, the operation data is stored in the operation data storage unit 27 by presetting a function matching the corresponding input according to the combination of the initial input of the optical sensor and the late input input according to the initial input. Therefore, if the late input according to the initial input is not detected within a predetermined time, the function of the operation data matching the initial input stored in the operation data storage unit 27 may be performed.

Here, when the function of the motion data matched to the initial input is performed, the function of the motion data may be differently set according to the time when the motion object enters the sensing area of the optical sensor. That is, a different function may be performed for each entry time of the operation object by presetting a time when the operation object enters the sensing region.

In detail, the motion of the operation object is detected in the sensing area of the optical sensor, and if the motion of the operating object is continuously detected for a predetermined time without a sensing signal of the sensing area of another optical sensor, the function of the motion data matched thereto. This can be done. In addition, when the motion of the operating object is detected by the optical sensor, and the motion of the operating object is not detected by another optical sensor for a preset time, the function of the motion data matched to the initial input may be performed.

For example, when the operation object is detected for more than 1 second in the third optical sensor 3 closest to the driver's seat, it may be a command for connecting and disconnecting the power of the navigation device 10. A function of muting the voice output unit 17 of the navigation device 10 may be preset.

On the other hand, when the movement of the operating object is detected in the sensing region of the optical sensor other than the optical sensor for which the initial input is detected within a predetermined time from the time of the initial input, the late processing input is detected by the operation processor 25. (S260).

In addition, the input initial input and the late input are compared with the operation data stored in the operation data storage unit 27 by the operation processor 25 (s270).

In operation S280, it is determined whether the combination and the operation data match. In detail, it is determined whether the sequential combination of the initial input and the late input is matched with the operation data corresponding to the combination stored in advance in the operation data storage unit 27.

Here, when the sequential combination of the initial input and the late input is not matched with predetermined motion data, the motion of the operation object is detected in the sensing area of the optical sensor other than the optical sensor in which the initial input according to the initial input is detected. By sensing, the late input is detected again by the operation processor 25.

When the sequential combination of the initial input and the late input is matched with the preset motion data, the function of the matched motion data is performed (s250) and is converted into an output signal by the controller 29 to display the display unit ( 13) is output.

On the other hand, the late input according to the initial input may be made a plurality of times. Specifically, if the operation data corresponding to the sequential combination of the late input input detected between the initial input and the last input is preset and stored in the operation data storage unit 27, the initial input, late input and final input. If a combination of inputs and the predetermined motion data match, the function of the motion data may be performed.

As such, the operation data matched with the combination of the initial input, the late input input, and the final input may be converted into an output signal by the controller 29 and output to the display unit 13.

Meanwhile, an embodiment of an operation method using an optical sensor of the navigation device 10 according to the present invention will be described with reference to FIGS. 2 and 5.

5 is a table showing preset operation data of an operation method using an optical sensor of a navigation device according to an embodiment of the present invention.

Here, the present invention will be described by way of example for the operation data consisting of the combination of the initial input and the late input is two times, for convenience of description, the late input according to the initial input is a sequential combination consisting of a plurality of times The operation data may be preset, and the operation data may be preset as the initial input without the late input. The predetermined function of the operation data is not limited to the function according to an embodiment of the present invention, and the function may be set differently for convenience.

On the other hand, as shown in Figures 2 and 5, the operation data matching the sequential combination of the initial input and the late input is preferably stored in the operation data storage unit (27 of FIG. 1). On the other hand, the optical sensor used in the navigation device 10 can be applied to the DMB function, for convenience of description to be limited to the DMB function in the vehicle navigation device 10 described.

In this case, the sequential combination of the first optical sensor 1 in which the initial input is detected and the third optical sensor 3 in which the late input is detected may be written as the operation data having a map enlargement function in the navigation device 10. It may be set and output to the display unit 13. In addition, when the DMB function is in service to the display unit 13, the display unit 13 may be preset as the operation data having a function of reducing the volume and output to the voice output unit 17 of FIG. 1.

That is, the operation object may enter the sensing area of each optical sensor by sliding movement over a predetermined distance without requiring a direct touch from the first optical sensor 1 to the third optical sensor 3. As a result, the map on the display 13 may be enlarged when the navigation service is in progress, and the volume output from the voice output unit 17 of FIG. 1 may be lowered when the DMB service is in use.

Here, the operation object is preferably to use the user's finger, it may be used a separate tool or the like depending on the situation and convenience.

In addition, when the initial input is detected by the third optical sensor 3 and the late input is detected by the first optical sensor 1, the operation data matching the combination of the initial input and the late input is transmitted in the navigation service. In the map reduction function and the DMB service, a function of increasing the volume may be preset and output.

In the sequential combination by the second optical sensor 2 and the fourth optical sensor 4, the function of the path indication of the navigation service and the next channel request of the DMB service may be preset in the operation data. In addition, the sequential combination of the fourth optical sensor 4 and the second optical sensor 2 may be configured such that the path cancellation of the navigation service and the previous channel request of the DMB service are preset in the operation data. It can be output at (13).

On the other hand, the operation data is preferably made to include an output conversion function for converting the output of the display unit 13 to the path display state during input in the search function, the output conversion function will be described with reference to FIG. Is the same as

As shown in FIG. 6, when the sequential combination of the initial input and the late input is matched with the output conversion function, the operation data includes storing data being input of the search function and a path according to the current position of the vehicle. And extracting data for display and converting the data for path display into an output signal.

In detail, when an initial input and a late input are detected through the optical sensor during the input of the search function (s300), the operation data according to the combination of the initial input and the late input is matched (s310), and the output conversion function It is determined whether the match with the operation data of (S320).

Here, if the sequential combination of the initial input and the sequential input does not match the motion data of the output conversion function, it is determined whether there is other motion data matching the sequential combination of the initial input and the sequential input (s330). If the other motion data matching the combination of the initial input and the late input is not extracted, an input wait state is entered, and when the other motion data matching the combination of the initial input and the late input is extracted, the initial input and the late step are extracted. The function of the operation data matched with the combination of the input is performed (S340).

On the other hand, if the sequential combination of the initial input and the late input is matched with the operation data of the output conversion function, the data being input of the search function is stored (S350). Here, the stored input data is restored due to the function of the operation data matched to the restoration combination of the input by the optical sensor during the next path display state. Accordingly, the restored input data may be input in connection with a state inputted by a previous search function.

When the data being input of the search function is stored, the route guide data according to the current position of the vehicle is extracted and converted into an output signal (S360), and the route display state is output through the display unit (S370).

For example, there is a situation in which signal waiting is to be started immediately after searching route information to find a desired path in the signal waiting state. In this case, the driver may drive while leaving the route information search window on the display unit 13 of the navigation device 10, and there is a possibility that an accident occurs while attempting to touch a button to output the route guidance function forcibly during driving. Increases.

In order to prevent the accident caused by this, the operation data is an example of a conversion combination for outputting the path display state even in a sudden start situation during the route information search, for example, the second light sensor (FIG. 2) from the first light sensor (1 in FIG. 2). It is preferable that the path display state for operation is output by the sequential input to 2). Here, the input data that was being searched for the route information is stored so that the driver is a restoration combination, for example, the sequential input from the second light sensor (2 of FIG. 2) to the first light sensor (1 of FIG. 2). Preferably, the search function is output to the display unit 13.
