Japanese Patent Laid-Open No. 2002-323850 (FIG. 1)

  However, in the above-described conventional navigation device, in order to stop the map scrolling at the place to be displayed, the map is scrolled by the driver because it is realized only by releasing the finger from the touch panel display when the place to be displayed appears. Since it is necessary to move the line of sight to the touch panel display for a considerable time during driving, there is a problem that it is very dangerous.

  Therefore, the present invention solves the above-described problems of the prior art, and provides an excellent navigation device that minimizes the time and interval for transferring the driver's line of sight to the touch panel display even when the map is scrolled during driving. With the goal.

  The navigation device of the present invention includes a touch panel display that displays a map, a touch movement distance detection unit that detects a length of movement of a finger that touches the touch panel display, a touch movement direction detection unit that detects a direction of movement, Map scroll distance calculating means for calculating a moving distance on the screen obtained from the touch moving distance detecting means from the scale of the displayed map as a map scroll distance, and a moving direction on the screen obtained from the touch moving direction detecting means. A map scroll direction calculating means for calculating a map scroll direction, a distance obtained from the map scroll distance calculating means, and a map scroll control means for scrolling the map in the direction obtained from the map scroll direction calculating means.

  With this configuration, the navigation device of the present invention allows the map to be scrolled together with the finger and the like when sliding on the map displayed on the touch panel display with the finger or the like. Scroll control is possible, and even when the map is scrolled during driving, the time and interval for transferring the driver's line of sight to the touch panel display can be minimized.

  Further, the navigation device of the present invention has a configuration including map scroll distance correcting means for correcting the map scroll distance obtained from the map scroll distance calculating means to an arbitrary magnification.

  With this configuration, when the navigation device of the present invention slides on the map displayed on the touch panel display with a finger or the like, the map scrolls with the finger or the like at a distance of an arbitrary magnification. This enables more detailed map scroll control, and even when the map is scrolled during driving, the time and interval for transferring the driver's line of sight to the touch panel display can be minimized.

  Further, the map scroll distance correction means of the navigation device of the present invention has a configuration including map scroll distance correction magnification setting means by which a user can arbitrarily set a magnification for correcting the map scroll distance.

  With this configuration, when the navigation device of the present invention slides on the map displayed on the touch panel display with a finger or the like, the map scrolls with the finger or the like at a distance of an arbitrary magnification designated by the user. Therefore, finer map scroll control is possible by the operation of the fingertip, and even when the map is scrolled during driving, the time and interval for transferring the driver's line of sight to the touch panel display can be minimized.

  According to the navigation device of the present invention, it is possible to scroll the map together with the finger etc. by sliding the finger etc. on the touch panel display, and the time and interval for the driver to move the line of sight to the touch panel display during driving are minimized. The effect that it can be limited is obtained.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1, 2, and 3.

  First, the configuration of the navigation device of the present invention will be described.

  As shown in FIG. 1, the navigation device according to the embodiment of the present invention includes a touch movement distance detection unit 101 that detects a distance that a finger touches a touch panel display and moves, and the finger moves on the touch panel display. Touch moving direction detecting means 102 for detecting the direction, and map scroll distance calculating means for calculating the scroll distance of the map based on the scale of the map displaying the moving distance on the touch panel display obtained from the touch moving distance detecting means 101. 103, a map scroll direction calculation unit 104 that calculates a map scroll direction based on the movement direction on the touch panel display obtained from the touch movement direction detection unit 102, and a map scroll distance obtained from the map scroll distance calculation unit 103. The map scroll distance is multiplied by The map scroll distance correction unit 105 for correcting the map scroll distance, the map scroll distance correction unit 105 for setting the magnification by which the map scroll distance correction unit 105 corrects the map scroll distance to the magnification set by the user, and the map scroll distance correction unit 105 Map scroll control means 107 for controlling the map scroll based on the map scroll distance obtained by the map scroll direction calculation means and the map scroll direction obtained by the map scroll direction calculating means.

  The map scroll distance correction magnification setting means 106 is for the user to input a magnification for correcting the map scroll distance and to set the map scroll distance correction means 105.

  The map scroll distance correction means 105 corrects the map scroll distance by multiplying the map scroll distance obtained from the map scroll distance calculation means 103 by the magnification set by the map scroll distance correction magnification setting means 106.

  When the user sets, for example, 1 as the magnification to be corrected in the map scroll distance correction magnification setting means 106, the map scroll distance correction means 105 outputs the map scroll distance obtained from the map scroll distance calculation means 103 as the map scroll distance as it is. . Further, when the user sets, for example, 2 as the magnification to be corrected in the map scroll distance correction magnification setting means 106, the map scroll distance correction means 105 sets the map scroll distance obtained from the map scroll distance calculation means 103 to twice the map scroll distance. Output as distance. On the other hand, when the user sets, for example, 0.5 as the magnification to be corrected in the map scroll distance correction magnification setting means 106, the map scroll distance correction means 105 maps half of the map scroll distance obtained from the map scroll distance calculation means 103 to the map. Output as scroll distance.

  Next, the operation of the navigation device of the present invention will be described with reference to the flowchart of FIG. First, it is determined by the touch movement distance detection means 101 whether or not a finger or the like has touched the touch panel (step S201). When it is determined that the touch has been made, the distance that the finger or the like has moved on the touch panel is detected by the touch movement distance detection unit 101 (step S202), and the movement direction of the finger or the like on the touch panel is detected by the touch movement direction detection unit 102. (Step S203). Then, the map scroll distance calculating means 103 calculates the map scroll distance from the moving distance on the touch panel and the scale of the displayed map (step S204), and the map scroll direction is calculated by the map scroll direction calculating means from the moving direction on the touch panel. (Step S205). Further, the map scroll distance calculated by the map scroll distance calculating unit 103 is multiplied by a magnification for correcting the map scroll distance set by the user using the map scroll correction magnification setting 106 so that the map scroll distance is calculated by the map scroll distance correcting unit 105. Correction is performed (step S206). A map scroll is executed by the map scroll control means 107 from the map scroll speed and the map scroll direction corrected in this way (step S207). Thereafter, it is determined by the touch movement distance detecting means 101 whether or not the finger is released from the touch panel (step S208). If it is determined that the finger is not released, the process returns to step S202 and the scroll operation is continued and it is determined that the finger is released. Then, the scroll operation is finished.

  In step S207, when the user sets, for example, 1 as the magnification to be corrected in the map scroll distance correction magnification setting means 106, the map scroll distance correction means 105 directly uses the map scroll distance obtained from the map scroll distance calculation means 103 as the map scroll distance. Therefore, the map is scrolled by a distance equivalent to the distance on the map on which the finger or the like has moved on the touch panel display. For example, 2 is set as a magnification that the user corrects to the map scroll distance correction magnification setting means 106. When set, the map scroll distance correction means 105 outputs twice the map scroll distance obtained from the map scroll distance calculation means 103 as the map scroll distance, so that the distance on the map where the finger or the like has moved on the touch panel display is displayed. Double the distance So that the map is scrolled. On the other hand, when the user sets, for example, 0.5 as the magnification to be corrected in the map scroll distance correction magnification setting means 106, the map scroll distance correction means 105 maps half of the map scroll distance obtained from the map scroll distance calculation means 103 to the map. In order to output as a scroll distance, in step S207, the map is scrolled by a distance that is half the distance on the map where the finger or the like has moved on the touch panel display. In this way, when the magnification to be corrected is set to be large, it is possible to scroll a long distance by moving a finger or the like slightly. Conversely, if the correction magnification is set small, only a short distance is scrolled even if the finger or the like is moved, so that the map can be carefully scrolled.

  The map scroll operation in the navigation device of the present invention will be described with reference to FIG. As shown in FIG. 3, when the user touches and slides on the map displayed on the touch panel display, the map also scrolls from the scroll start position 501 to the scroll end position 502 together with the fingers.

  In the present embodiment, the finger touches the touch panel display to scroll, but it goes without saying that the touch panel display can be anything other than the finger, such as an input pen.

  As described above, in the navigation device of the present invention, it is possible to scroll the map so that the map is accompanied by sliding the touch panel display with a finger or the like. Further, the distance for scrolling the map can also be set to a distance of an arbitrary magnification of the distance on the map on which the finger or the like has moved on the touch panel by setting a magnification to be corrected by the user in the map scroll distance correction magnification setting means 106. it can. Therefore, detailed map scroll control is possible with the movement of the fingertip, and even when scrolling the map while driving, the time, number of times and interval to move the driver's line of sight to the touch panel display can be minimized. It can be done safely.

  As described above, according to the navigation device of the present invention, it is possible to scroll the map together with the finger by sliding the finger on the touch panel display, and the driver moves his / her line of sight to the touch panel display during driving. Since time and intervals can be minimized, it is possible to contribute to the realization of safe driving.
