Furthermore, the event detection unit 130 of the road guidance system 100 using a vibration pattern according to an embodiment of the present invention may detect a time difference between a direction event and a danger event.

For example, a direction event of a left turn direction event or a right turn direction event and a risk event of a dangerous situation risk event or a risk event of a route departure may occur at the same time, or may occur with a short time difference. Accordingly, the event detection unit 130 may detect a direction event and a danger event separately, and the road guidance system 100 using a vibration pattern according to an embodiment of the present invention is In the case of occurrence of a time difference, a higher weight is added to the risk event to provide priority to a vibration pattern for the risk event.

Hereinafter, a vibration pattern provided by the vibration guide 140 according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

2 illustrates an example of a vibration pattern corresponding to each event according to an embodiment of the present invention.

1 and 2, the vibration guide 140 includes a left turn direction event of FIG. 2(a), a right turn direction event of FIG. 2(b), a risk event of FIG. 2(c), and a risk event of FIG. It is possible to provide different vibration patterns for each of d)'s off-path risk events.

When the left rotation direction event occurs as shown in FIG. 2(a), the vibration guide 140 according to the embodiment of the present invention is compared with the first vibration 210 and the first vibration 210, which exhibit a relatively short vibration time. A vibration pattern that continuously repeats the second vibration 220 representing a relatively long vibration time may be provided. For example, the first vibration 210 may indicate a short vibration of about 0.5, and the second vibration 220 may indicate a long vibration of about 1 second.

According to an embodiment, the vibration guide 140 may provide a vibration pattern in which the first vibration 210 and the second vibration 220 are continuously repeated about three times when a left rotation direction event occurs.

When the right rotation direction event occurs as shown in FIG. 2(b), the vibration guide 140 according to the embodiment of the present invention is compared to the second vibration 220 and the second vibration 220 indicating a relatively long vibration time. A vibration pattern that continuously repeats the first vibration 210 representing a relatively short vibration time may be provided. For example, the second vibration 220 may represent a long vibration of about 1 second, and the first vibration 210 may represent a short vibration of about 0.5 seconds.

According to an embodiment, the vibration guide 140 may provide a vibration pattern in which the second vibration 220 and the first vibration 210 are successively repeated about 3 times when a right rotation direction event occurs.

In the road guidance system 100 using the vibration pattern according to an embodiment of the present invention, the vibration pattern provided in the event of the left turn direction or the right turn direction is changed only in the order of the first vibration 210 and the second vibration 220, Even a simple vibration pattern can give effective direction instructions to the user. In this case, the first vibration 210 and the second vibration 220 provided in a right-hand direction event or a left-hand direction event represent different vibration times, but have the same vibration intensity.

When a risk event occurs as shown in FIG. 2(c), the vibration guide unit 140 according to the embodiment of the present invention responds to the third vibration 230 and the third vibration 230 indicating a relatively strong vibration intensity. It is possible to provide a vibration pattern in which the fourth vibration 240 indicating a relatively weak vibration intensity is continuously repeated. For example, the third vibration 230 may represent a strong vibration, and the fourth vibration 240 may represent a relatively weak vibration compared to the third vibration 230.

According to an embodiment, the vibration guide 140 continuously repeats the third vibration 230, which is a strong vibration, and the fourth vibration 240, which is a weak vibration, as a siren-shaped vibration when a dangerous event occurs. Vibration patterns can be provided.

When a path departure risk event occurs as shown in FIG. 2(d), the vibration guide unit 140 according to the embodiment of the present invention provides a vibration pattern that repeats the third vibration 230 indicating a relatively strong vibration intensity. I can.

According to an exemplary embodiment, the vibration guide 140 may provide a vibration pattern in which the third vibration 230 indicating a strong vibration intensity is continuously repeated about three times.

When a path departure risk event occurs, the control unit 150 according to an embodiment of the present invention may provide a user with a reverse function of returning a wrong path.

In the road guidance system 100 using a vibration pattern according to an embodiment of the present invention, the vibration pattern provided in the event of a dangerous situation or a risk of path departure is repeatedly used by the third vibration 230 and the fourth vibration 240 Alternatively, by repeatedly using only the third vibration 230, an effective direction instruction can be given to the user with only a simple vibration pattern. In this case, the third vibration 230 and the fourth vibration 240 provided in a dangerous situation risk event or a path departure risk event exhibit different vibration strengths, but exhibit the same vibration time.

That is, the horizontal length of the first vibration 210, the second vibration 220, the third vibration 230, and the fourth vibration 240 shown in FIG. 2 indicates the vibration time, and the vertical height indicates the vibration intensity. have.

Furthermore, the road guidance system 100 using a vibration pattern according to an embodiment of the present invention provides a vibration pattern differently designated for each event only for four events such as left turn, right turn, dangerous situation, and route departure, It is possible to minimize user confusion by limiting the situation in which the pattern is provided, and minimize errors in directions by making the contrast between vibration patterns having different vibration periods, vibration intensity, and vibration frequency sharp.

Referring back to FIG. 1, the control unit 150 of the road guidance system 100 using a vibration pattern according to an embodiment of the present invention searches for route guidance information reset at a departure point and a destination when a dangerous event occurs, and an information acquisition unit Provided to (110).

When a dangerous event occurs, the control unit 150 may re-search the reset road guidance information in order to solve a dangerous situation or route deviation generated from the road guidance information and provide the re-searched route guidance information to the information acquisition unit 110.

In more detail, the controller 150 may re-search for re-established route guidance information, which is a new route at the same origin and destination, when an obstacle positioned in front of the path at the user's current location or a dangerous situation due to an accident occurs. , In the event of a route departure risk event that deviates from the route guidance information, the reset route guidance information, which is a way back the user's past, may be re-searched.

For example, when a dangerous event occurs, the control unit 150 may re-search for reset route guidance information, which is a new route outside the area where the dangerous event occurred at the departure point and destination selected by the user, and the re-searched route guidance information May be provided to the information acquisition unit 110.

As another example, when a route departure risk event occurs, the controller 150 may re-search for reset route guidance information in which a user who has moved according to the route guidance information returns the route. For example, if the user deviates from point C while moving from point A to destination point B, the controller 150 sets point C as the point of departure and point A as the destination to reset the route. Guidance information may be re-searched, and the re-searched route guidance information may be provided to the information acquisition unit 110.

However, when the user deviates from the route from point C, it is inefficient to reach point A as the destination, so the controller 150 re-searches the route guidance information reset from point C to point A, and the information acquisition unit ( 110), and if the user deviates from point C and is located in the existing route guidance information, the information acquisition unit retrieves route guidance information from the user's location to the destination of point B from the origin of point A again. It can be controlled to provide via 110.

When the deaf or visually impaired departs the route, it is more important to provide guidance on the return route rather than the new route, and it is safer to guide the existing route guidance information after returning a certain distance from the point of departure from the route.

When the event detection unit 130 detects the direction event and the risk event at the same time or with a short time difference, the control unit 150 adds a higher weight to the risk situation or the risk event of path deviation than the direction event of left or right turn. The vibration guide 140 may be controlled to preferentially provide a vibration pattern for an event to a user.

For example, when a user turns right according to a right turn direction event generated at branch D, if a staircase is located in front of the path of the user who has turned right, the event detection unit 130 shortens the right turn direction event and the danger event. It can be detected by time difference. Accordingly, even in a situation in which the vibration pattern for the right turn direction event has been provided preferentially through the vibration guide unit 140, the control unit 150 adds a higher weight to the dangerous situation risk event to determine the vibration pattern according to the right turn direction event. It is possible to control the vibration guide 140 to stop and provide a vibration pattern for a dangerous situation or a dangerous event.

Moreover, the vibration guide 140 provides priority to the vibration pattern for the dangerous situation and the risk event, and then continuously provides the vibration pattern for the right-turn direction event and the vibration pattern for the dangerous situation It can additionally inform you that a dangerous situation may occur if you turn right.
