As such a miniature electric actuator can be selectively used because there are many known products, the detailed description thereof will be omitted in order to prevent the object of the present invention from being blurred.

In this case, the driving unit 120 configured as the electric actuator is provided with a number smaller than the number of one or more of the guide protrusions 112, and the position of the driving unit 120 may be moved as needed to selectively raise the necessary guide protrusions. Preferably, the driving unit 120 is provided in the same number as the guide protrusions 112, but each is installed at the bottom of each guide protrusion 112 to be configured to raise a plurality of guide protrusions at the same time.

As the present invention can be used as a clock with a direction guide function, as shown in the accompanying drawings, the through hole 111 is made up of twelve hours and minutes through a guide protrusion 112 inserted thereto. It is configured to be able to, and the drive unit 120 is also provided with 12 is configured to drive each guide protrusion 112 individually.

In addition, in the present invention, the body portion 110 includes the interface 130, the direction detecting unit 140, the controller 150, the timer 160, and the operation selection unit 170.

The interface unit 130 is a component for receiving input from the user, the target location information including the designated direction and distance. In this case, the destination location information is information indicating a destination to which the user wants to go. If the destination is input as the destination location information in a situation where the user's current location is given together with map information, the designated direction and distance from the current location to the destination are indicated. The calculation of can be done through a conventional path finding program.

To this end, the present invention may be linked with a smart phone capable of providing map information or a terminal providing an equivalent function, or a separate storage unit (not shown) capable of receiving and storing the same.

In addition, it is also possible to build the interface unit 130 by installing a small touch screen on the body portion 110, in consideration of ease of use and manufacturing and power management mainly for the visually impaired It is preferable to configure the interface unit 130 of the voice input and output method, and for this purpose, the voice input unit 131 for generating the target position information by recognizing the voice input from the user and the corrected designation direction and distance according to the correction information described below. It is preferable to have a voice output unit 132 for outputting the voice.

In addition, a connector 133 or a wireless communication module 134 for a wired connection that can receive the target location information from an external device, such as the terminal described above may be selectively provided, which is mainly active By storing the map (geography) information on the inside and outside places or the map information as necessary in the body 110 in advance, the input and direction calculation of the target location information including the designated direction and distance can be performed smoothly.

The direction detecting unit 140 is configured to generate correction information for the moving distance and the rotation direction of the body unit 110 based on the target position information input through the interface unit 130.

In the present invention, the guide projection corresponding to the direction of the destination is basically raised based on the current position of the user having the body 110, so that the user is guided in the direction to proceed. Since the direction of the raised guide protrusion is relative to the position and the direction of the user, when the user moves or turns the body, the direction and the distance of the guided destination must also be calculated again.

Accordingly, the direction detecting unit 140 basically measures the moving distance and the rotation direction of the body 110 and generates correction information for the input destination, that is, the target position information.

To this end, the direction detecting unit 140 is provided with a GPS module, a geomagnetic sensor, a gyro sensor, an acceleration sensor selectively, and the measurement of the rotation distance and the rotation direction based on the geomagnetic field according to the user's movement. Preferably, all of the mentioned modules and sensors are provided so that more accurate correction information can be generated by linking them, and by storing and storing the movement distance calculated by the gyro sensor and the acceleration sensor according to the user's gait. Later, the measured value can be compared with the stored data to increase the accuracy.

The controller 150 generates a control signal for raising the guide protrusion at a corresponding position to indicate a direction according to the correction information generated by the direction detecting unit 140 and applies it to the driving unit 120.

At this time, by basically raising one guide projection corresponding to the direction of the destination from the center of the body 110, the user can smoothly check the direction to the destination through the tactile sense. Preferably, it can be modified to raise the guide protrusions located on both sides of one guide protrusion corresponding to the direction of the destination, that is, three guide protrusions as shown in the drawing, so that it can be quickly and accurately grasped.

In this case, the height of the three guide protrusions guiding the destination may be the same, but it may be a very effective method to differentiate the heights of the guide protrusions and the guide protrusions located at both sides in the middle of the direction. That is, the middle guide protrusion is high and the guide protrusions on both sides can be controlled to protrude relatively low.

In addition, if the distance to the destination is relatively far, that is, if the distance is greater than the set distance by applying this, as described above, the direction is guided through the three guide protrusions, and if the distance to the destination is less than the set distance, the direction is changed through one guide protrusion. The tactile sense of distance can also be guided.

The timer 160 is a circuit or element that literally calculates a time. The timer 160 generates current time information, and generates a control signal to raise and raise the guide protrusion at a position corresponding to the hour and minute according to the time information. It generates and applies to the drive unit 120.

That is, the guide protrusions representing the time and the guide protrusions representing the minute in 5 minutes are respectively raised so that the user can know the current time and minute through the tactile sense. Preferably, the height of the guide protrusions representing the time and the guide protrusions representing the minute are shown. By differently it is possible to grasp the hour and minutes more quickly and effectively for this purpose, the drive unit is configured to adjust the height of the guide projection in at least two stages. In this case, the user can check the minutes in 5 minute increments.

Of course, it is also possible to more precisely understand the time in minutes by allowing a more precise control of the height of the driving unit instead of the two-step height adjustment.

The operation selecting unit 170 is configured to receive a selection from the user for the use of the present invention for use as a direction guide and the use of the clock, preferably a switch formed on the side of the body portion 110 as shown in the accompanying drawings It is configured in the form so that the user can select the time mode or direction mode.

At this time, when the user selects the time mode, the control signal of the timer 160 is applied to the driving unit 120 so that the user can grasp the time through the protrusion of the guide protrusion, and when the user selects the direction mode, the control of the controller 150 is performed. The signal is applied to the driver 120 to determine the direction of the destination through the protrusion of the guide protrusion.
