    Remote Control Unit for Navigation System
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control apparatus for navigation apparatus, and more particularly, to a remote control apparatus for navigation apparatus employing a touch pad.
    In general, home appliances such as televisions and VTRs are mostly equipped with a remote controller. The remote controller is equipped with a direction key for inputting four directions of left, right, up and down as direction keys. With these direction keys, the menu displayed on the screen can be selected.
    1 is a block diagram of a conventional remote control device for a vehicle navigation system. Referring to FIG. 1, a conventional remote control device for a vehicle navigation system includes an eight-direction key 10 for selecting eight directions, a function key 20 for selecting a function, and an infrared ray output for outputting an input content to an infrared ray 31. The unit 30 is composed of a microcomputer 40 for controlling the operation of the remote control device.
    Normally, a navigation device installed in a vehicle displays on a monitor when displaying a map. The remote control unit is used as an input device when the user scrolls the map or selects a menu displayed on the monitor. The remote control device used in the conventional navigation device is provided with a direction key 10 for inputting eight directions. 2 shows an eight-way key 10 of a conventional remote control device for a vehicle navigation system. Referring to Fig. 2, each of the directions 11, 12, 13, 14, 15, 16, 17, and 18 of the eight-way key 10 is divided at intervals of 45 degrees. When scrolling the map displayed on the monitor in a desired direction, the user scrolls using the direction keys 10.
    3 is a flowchart of a conventional remote control device for a vehicle navigation system. 4 is a diagram illustrating a scroll speed of a screen in proportion to the time when the eight-way key is pressed. Looking at the operation of the conventional remote control device for a vehicle navigation system as follows.
    When the user scrolls the map by pressing the direction key 10, the microcomputer 40 first determines whether the direction key 10 is pressed (S10). If the direction key 10 is pressed, the microcomputer 40 turns on the counter 41 and increases the counter value (S20). Then, the counter value and the threshold counter value are compared (S30). If the counter value in the comparison (S30) is less than the threshold counter value, the navigation apparatus main body 60 scrolls the map displayed on the screen at a preset 1x speed (S31) (tilt of Fig. 4 (a)). And the counter value is increased (S32). After the counter value increases (S32), the direction key pressing determination step (S10) is performed.
    By the way, in the comparison of step S30, if the counter value is larger than the threshold counter value (when the time pressing the eight-way key 10 in Fig. 4 is greater than (C)), the counter 41 is stopped. After the counter stops, the infrared receiver 50 receives the infrared signal transmitted by the infrared transmitter 30 and transmits the infrared signal to the navigation apparatus main body 60. The navigation device main body 60 scrolls the map displayed on the screen at a speed of 2 to 3 times the speed (inclination of (b) of FIG. 4) preset in the direction in which the eight-way key 10 is pressed in step S10. Let's do it. That is, the map displayed on the screen is first scrolled at a preset 1x speed when the 8 direction keys 10 are pressed, and then scrolls at 2x or 3x speed of the initial speed after a predetermined time elapses.
    However, the direction key 10 of the conventional remote control apparatus supporting eight directions does not control the angle between 45 °. In addition, when the direction key 10 is pressed in the direction to be scrolled, the scroll speed is determined according to the time when the direction key 10 is pressed. In addition, it is difficult to rotate the map displayed on the screen in an arbitrary direction, and since the direction key 10 operates mechanically, there is a short lifespan.
    The present invention is to solve the above problems, by employing a touch pad (Touch pad) the user can scroll the map displayed on the monitor in the desired direction and the desired speed and a remote control device for navigation device that can rotate the screen The purpose is to provide.

When moving to, the navigation system scrolls the map displayed on the monitor according to the movement. In step 1, when the user touches a point centered on the notch of the touchpad and rotates the contact to another point, the navigation device appears as much as the rotated angle. And a screen rotating step of rotating the map.
    The touch pad is a kind of pointing device and is commonly used as an indication device such as a notebook computer that can be carried. In general, the touchpad inputs using a user's finger. The user moves the pointer on the touch pad in a desired direction while rubbing the finger on the touch pad.
    Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.
    5 is a block diagram of a remote control apparatus according to the present invention. Referring to FIG. 5, the remote control apparatus for navigation apparatus according to the present invention includes a touch pad 80 for inputting using a finger, a function key 20 for inputting various functions, and an input signal of an optical signal. Infrared transmission unit 30 for outputting a microcomputer 40, and the like to control the remote control device.
    6 is a schematic diagram of a touch pad of the remote control device for navigation apparatus according to the present invention. Referring to FIG. 6, the touch pad 80 according to the present invention is located at the center of the touch pad 80 and the touch pad 80, which a user can input using a finger, and a notch part for double-clicking ( 81).
    7 is an operation flowchart of a remote control device for navigation apparatus according to the present invention.
    8 is an explanatory diagram of a screen scroll by the remote control apparatus for navigation apparatus according to the present invention.
    9 is an explanatory diagram of screen rotation by the remote control apparatus for navigation apparatus according to the present invention.
    First, the microcomputer 40 determines whether the user presses the touch pad 80 with a finger (S100). If it is determined in step S100 that the touch pad 80 is pressed, it is determined whether there is a start signal (S110). The start signal means that the user presses the notch 81 on the touch pad 80.
    If it is determined in step S110 that the start signal has been detected, the microcomputer 40 detects the movement of the user's finger moving on the touch pad 80 to detect the direction, speed, and rotation (S120). In this case, the direction is the direction in which the finger moves in the notch part 81 of the touch pad 80, and the speed is a speed proportional to the distance the finger moves in the notch part 81 of the touch pad 80. In other words, the longer the moving distance, the faster the speed. In addition, whether to rotate is how much the user's finger rotates about the notch 81 of the touch pad 81. If the direction and the speed is detected, the microcomputer 40 transmits the data to the navigation device body through the infrared transmitter (S130). The navigation device body 60 scrolls the map displayed on the screen display unit 70 by the data received by the infrared receiver 50.
    Looking at the map displayed on the screen display unit 70 scrolls as the user's finger moves on the touch pad 80 as follows.
    Referring to FIG. 8, it is assumed that a user moves a finger to another point A ′ using the notch 81 of the touch pad 80 as the center point A. The navigation device body 60 scrolls a map displayed on the screen display unit 70 in a direction (A to A 'direction) in which a finger moves about the notch 81 on the touch pad 80. At this time, the scroll speed of the map is a speed proportional to the moving distance L of the user's finger. And, with reference to FIGS. 9A and 9B, a user moves his / her finger from the point B to another point B 'about the notch 81 of the touch pad 80 at an arbitrary angle Θ. Suppose we move by: When the user rotates the finger, the screen C before the user moves the finger is rotated and displayed by the angle Θ that the user's finger is rotated (C ').
    If it is determined in step S110 that there is no start signal, the microcomputer 40 determines whether a double click is made (S140). If it is determined in the determination (S140) that the double click is made, the microcomputer 40 transmits the corresponding signal for the double click through the infrared transmitting unit (S150). Then, the start signal is released (S160). However, if it is determined that the double click is not made in the determination (S140), the microcomputer 40 registers the start signal because the touch pad 80 is pressed and the double click is not made, and the start signal is transmitted to the navigation apparatus through the infrared transmitter. Transfer to (S142).
    If the touch pad 80 is not detected in the determination (S100), the microcomputer 40 determines whether a start signal exists (S170). If the start signal does not exist, the signals of all the touch pads 80 are released (S171).
    If it is determined in step S170 that the start signal exists, it is determined whether it is a double click (S180). If the double click is not made in the determination (S180), a timer is set (S181). The reason for setting the timer is to determine whether a start signal exists and whether a double click is made within a predetermined time. If it is determined in the determination (S180) that the double click, it is determined whether the time is exceeded (S190). If it is determined in step S190 that the time is exceeded, the timer is released (S200).
    In the present embodiment, data is transmitted and received using infrared rays, but radio waves may be used and data may be transmitted by wire instead of wirelessly. In addition, the remote control device having the above-described function may be mounted anywhere in the form of an independent remote control device as well as a monitor of a navigation device or a navigation device.
    As described in detail above, the scrolling of the map displayed on the screen of the navigation device monitor by the remote control device for navigation device according to the present invention moves the finger on the built-in touch pad when the notebook computer is used. As if moving around on the monitor, the user moves the finger on the touchpad of the navigation device remote control according to the present invention to scroll the displayed map on the screen as much as desired. That is, the user may scroll in a desired direction and speed according to the movement of the user's finger. You can also rotate the map displayed on the screen in any direction. And since the touchpad has no mechanical contact as compared to the mechanical switch, the touchpad can extend the life of the device.
