Description

  The present invention relates to a mobile navigation device that is mounted on a car or carried by an operator, and more particularly to a navigation device having a novel map scrolling function. In addition, although this invention is a navigation apparatus of a mobile body, the example of a motor vehicle is demonstrated for convenience of explanation.

  In a navigation device mounted on a general automobile, a GPS signal from a GPS satellite, a gyro signal from a gyro sensor, a vehicle speed pulse signal from a vehicle speed sensor, etc. are obtained to obtain the current automobile position (coordinate values indicated by latitude and longitude). ), The direction of travel of the car, the traveling speed, etc., and map data including road data stored in a recording medium such as a DVD-ROM or hard disk is searched to include the current car position (coordinates). And the map and the vehicle position mark are displayed on the display screen of the navigation device so that a triangular icon (hereinafter referred to as the vehicle position mark) indicating the position of the vehicle is located at a predetermined position based on the read map data. To be displayed.

By the way, the display device of the navigation device has a touch panel equipped with a pointer function on the display screen itself so that the user can directly specify and select various setting functions using menus and destination points and registered points with a finger. Widely used.
Then, when a map is displayed on such a touch panel type display screen (hereinafter referred to as a touch panel screen) and an arbitrary place on the touch panel screen is pressed and specified, until the specified point comes to the center of the touch panel screen A technology that allows the map to scroll is adopted.

  However, when the point to be displayed is outside the display range of the touch panel screen, this operation is repeated, but in the case of such a scroll method, the desired map can be obtained by scrolling in any direction. There is a problem that it is not easy to use because some skill is required.

For this reason, when an arbitrary position on the touch panel screen is pressed with a finger to instruct a scroll request, first, arrow-shaped icons extending radially in a predetermined number of directions (for example, 8 directions) are displayed on the touch panel screen. A navigation device having a scroll mode in which a screen is scrolled in a direction indicated by an arrow by specifying the displayed position with a finger has been proposed.
In the case of this method, scrolling is continuously performed while an arrow-shaped icon displayed on the touch panel screen is specified by pressing with a finger.
However, in this method, while scrolling, the arrow on the touch panel screen must be specified by pushing with a finger, which is a burdensome operation for the user.
JP 2001-108475 A

  As a technique for reducing the user's burdensome operation, as specified in Japanese Patent Application Laid-Open No. 2001-108475, the scrolling speed is increased by specifying the time when the touch panel screen is pressed with a finger or the distance from the center of the screen. There are things that allow you to shorten the time you are doing, but you could not change the scrolling speed arbitrarily and freely, which was also unusable. For this reason, it was not possible to adequately answer the desire to scroll the map quickly to the destination point or the desire to scroll while checking the map.

  In view of such a point, the present invention includes a novel map scroll operation device having a scroll mode in which scrolling can be easily performed by pressing the touch panel screen with a finger without continuing to specify. An object is to provide a navigation device.

The first feature of the present invention is:
When scrolling of the map is instructed by the touch sensor, a direction mark indicating a plurality of scroll directions and a speed mark indicating an increase or decrease in scroll speed are displayed on the map displayed on the display screen, and one direction mark is displayed. When the touch sensor detects that is selected, the map is scrolled in the selected direction, and the map is scrolled at a speed selected by the speed mark.
The second feature of the present invention is that
When the scroll direction of the map is determined from the point specified by the touch sensor, a speed mark indicating an increase or decrease in the scroll speed is displayed, and the speed mark is selected while scrolling the map, and the scroll speed is determined by the attribute of the mark. The map is scrolled with increasing or decreasing.

  By providing the means described above, the user can scroll with a simple operation, so that a map of a desired place can be displayed quickly and the scroll speed can be easily changed. Therefore, it is possible to perform scrolling according to the operator's request, such as being able to scroll to the destination point quickly or scrolling while checking the map.

  An embodiment of the present invention will be described in detail below with reference to the drawings. However, it is needless to say that the present invention can be variously modified and applied without being limited to the embodiment described below.

The sensor unit 30 includes an azimuth sensor 31 and a gyro 32. The azimuth sensor 31 detects the direction of the automobile by detecting the magnetic field of the earth. The gyro 32 includes an optical fiber gyroscope, a vibration gyroscope, and the like. Used to detect the angle of rotation of the car.
The signals detected by the azimuth sensor 31 and the gyro 32 are converted into digital signals by an analog-digital converter (A / D) 34 and sent to the arithmetic processing unit 10 via the internal bus 70.

  Further, the sensor unit 30 includes a wheel speed sensor 33. The wheel speed sensor 33 detects a travel distance signal of the automobile by counting a pulse signal output with the rotation of the wheel by a counter 35. Similarly, the distance signal is sent to the arithmetic processing unit 10 via the internal bus 70.

  The GPS signal receiving unit 51 receives a signal from a GPS satellite via the GPS antenna 54, and measures the distance between the vehicle and the satellite and the rate of change of the distance, whereby the current position, traveling direction, and traveling direction of the vehicle. These measurement data are sent from the SCI (Serial Communication Interface) 53 to the arithmetic unit 10 via the internal bus 70.

  Further, the FM information receiving unit 52 periodically receives the VICS information superimposed on the FM broadcast via the FM multiplex receiver 55, and imports traffic information such as traffic jam information, traffic regulations and traffic accident occurrence information from the SCI 53. The data is sent to the arithmetic unit 10 via the bus 70. Such traffic information is displayed on the display unit 40 together with the map information.

The display unit 40 includes display control means including a display driver 41, a controller 43, a buffer 44, and the like, and a liquid crystal panel 42, and stores data sent from the arithmetic processing unit 10 via the internal bus 70 in the buffer 44. Based on this, the display device 42 displays a map, a guidance route, a vehicle position, and the like.

In addition, the controller 43 receives signals from a number of touch sensors provided on the touch panel 45 installed on the liquid crystal panel 42 and performs processing for detecting a position pressed by a user's finger or the like. Information is sent to the CPU 11 as an interrupt signal.
A display screen obtained by combining the liquid crystal panel 42 and the touch panel 45 provided with a touch sensor is expressed as a touch panel screen 100 as shown in FIG.

The input / output unit 60 is a key PAD 62 configured by a hard switch or a jog switch that receives an instruction from the user, a remote control light receiving unit 61 that receives an optical signal from a remote control 65 operated by the user, and a user generated by the arithmetic processing unit 10. Is converted to a voice signal by a speaker (SP) 66, and a voice code inputted through a microphone 68 is taken in and converted by a CODEC 63 or the like.
These exchange data with the arithmetic processing unit 10 via a PIO (Port Input / Output) 64 and an internal bus 70.

  FIG. 2 shows an example of scroll operation keys displayed on the touch panel screen 100, and an arrow-type scroll direction designation icon which is a direction mark indicating a scroll direction as a scroll parameter in the form of being overwritten on the displayed map. 120 and a scroll speed designation icon 140, which is a speed mark for designating increase and decrease of the scroll speed, is displayed.

As shown in FIG. 2, the scroll direction designation icon 120 extends radially in eight directions on the touch panel screen 100 and is displayed so that the center of the scroll direction designation icon 120 coincides with the center of the touch panel screen 100. It has become so.
A scroll speed designation icon 140 for designating increase and decrease of the scroll speed is displayed in the lower left area of the touch panel screen 100.

On the left side of the outer frame of the touch panel screen 100, a detail key 102, a wide area key 104, a current location key 106, a menu key 108, and a jog key 110 as hard keys are provided.
The detail key 102 is a function key for reducing the scale of the displayed map and displaying the map in more detail, and the wide area key is a function for increasing the scale of the displayed map and displaying a wider area. The current location key 106 is a function key for displaying a map of the area where the automobile is currently located, and the menu key 108 is a function key for displaying a menu representing various display functions and search functions. The jog key 110 is a function key for selecting a displayed menu, for example.

  Next, a series of processing operations relating to scrolling in the navigation apparatus will be described with reference to FIGS. Here, FIG. 4 is a flowchart showing the process of the navigation device until the scroll process is performed.

  First, as shown in FIG. 3, when an operator presses an arbitrary place on the touch panel screen 100 with a finger while the vehicle position mark and the map around the vehicle position mark are displayed on the touch panel screen 100, the touch panel The touch sensor on the screen 100 sends a scroll request signal to the controller 43, and the controller 43 sends the scroll request signal to the CPU 11 via the internal bus 70 to be a scroll interrupt signal for the CPU 11.

  Upon receiving this interrupt signal, the CPU 11 starts touch panel interrupt processing as shown in FIG. 4, and scrolls the display unit 40 in the scroll direction as shown in FIG. The scroll direction designation icon 120 for designating the scroll speed and the scroll speed designation icon 140 for changing the scroll speed are displayed.

  Thereafter, the process proceeds to S104, and it is determined whether or not a predetermined time (for example, 15 seconds) has elapsed since the scroll direction designation icon 120 and the scroll speed designation icon 140 are displayed. If the icon is pressed within a predetermined time, it is determined that the scroll operation is continuously requested, and if the icon is not pressed within the predetermined time, it is determined that the touch panel 100 screen is erroneously pressed. is there.

When it is determined in the determination step of S104 that a predetermined time such as 15 seconds has elapsed (in the case of “Y”), the process proceeds to S106, and the display of the scroll direction designation icon 120 and the speed designation icon is stopped, as shown in FIG. Return to normal map display processing.
On the other hand, if it is determined in S104 that the predetermined time has not elapsed (in the case of “N”), the process proceeds to S108, and it is determined whether any one of the scroll direction designation icon 120 and the scroll speed designation icon 140 has been pressed.

  If neither the scroll direction designation icon 120 nor the scroll speed designation icon 140 is pressed in S108 (in the case of “N”), the process returns to S104 again, while either the scroll direction designation icon 120 or the scroll speed designation icon 140 is selected. When is pressed (in the case of “Y”), the process proceeds to S110 and shifts to the scroll mode.

Next, after shifting to the scroll mode of S110, it is determined whether or not the icon pressed by the user in S112 is the scroll direction designation icon 120. This is because the scroll speed adjustment itself is not established unless the scroll direction is selected.
Therefore, when the icon pressed in S112 is not the scroll direction designation icon 120 (in the case of “N”), the process returns to S104 again and the same processing is repeated.
On the other hand, if the pressed icon is the scroll direction designation icon 120 (in the case of “Y”), the process proceeds to S114 to update the scroll direction data.
Then, the process proceeds to S116 to start the scrolling process, which will be described in detail with reference to FIG.

Next, when the scroll process in S116 is completed and the map is in a scroll stop state, the scroll direction designation icon 120 is displayed again in S118, and then the process returns to S104 and waits for the touch panel screen 100 to be pressed.
In addition, although the distance on the map to be scrolled until the end of scrolling is not shown in detail, for example, it may be scrolled in mesh units that match the scale of the currently displayed map, or in 1/2 mesh units, Scrolling within a predetermined distance range may be arbitrarily determined.

Next, the detailed operation of the scroll process described with reference to FIG. 4 will be described with reference to FIG.
When the mode for executing the scroll process is entered in S116 of FIG. 4, first, the scroll direction and speed data stored in a predetermined area provided in the DRAM 13 are read in S200, and the scroll direction selected based on the data is read in S202. Scrolling starts at a predetermined speed.
At this time, the scroll speed is determined to be a predetermined initial setting speed, and is then increased or decreased as designated by the user as the reference scroll speed. In this embodiment, the scroll direction designation icon 120 is no longer necessary and is deleted, but if necessary, the scroll direction designation icon 120 may be scrolled while being displayed.

  Thereafter, the process proceeds to S204, where it is monitored whether the touch panel screen 100 has been pressed again, and the process proceeds to S206 to determine whether the user requests adjustment of the scroll speed, and the touch panel screen 100 is pressed ("Y"). In the case of (), it is determined whether or not it is the scroll speed change icon 140.

If it is determined in S206 that the scroll speed change icon 140 has been pressed, the process proceeds to S208 to update the scroll speed data and adjust the scroll speed.
Here, in the scroll speed change icon 140 in FIG. 2, the arrow on the upper side of the screen is given an attribute indicating an increase in the scroll speed, and the arrow on the lower side of the screen is given an attribute showing a decrease in the scroll speed. . Therefore, the scroll speed is increased or decreased depending on which arrow is selected.

  When the scroll speed adjustment is executed in S208, the process returns to S204 to monitor the touch on the touch panel screen 100 again. For example, when the previous scroll speed adjustment is an increase direction request, the increase direction request again. Is instructed by the scroll speed change icon 140, the scroll speed is further increased from the scroll speed at this time, and the map is scrolled. Conversely, when the adjustment of the scroll speed is a request for decreasing direction, the scroll speed is decreased and the map is scrolled.

If the scroll speed change icon 140 is not pressed in S206 (in the case of “N”), the process proceeds to S210 to stop the scrolling of the map, and returns to the process of S118 of FIG. 4 to execute the next process.

  By executing the process as described above, a new map scroll operation device that has a scroll mode that can easily change the scrolling speed can be scrolled without pressing the touch panel screen with a finger and continuing to specify. A navigation device can be provided.

  In this embodiment, the scroll speed change icon 140 for increasing and decreasing the scroll speed is displayed. However, as shown in FIG. 7, the scroll speed change icon 140A is divided into several stages as shown in FIG. The speed may be specified. In this case, the scroll initial setting speed is set to the lowermost square portion, and the scroll speed is set to increase as it goes upward.

  Further, hard keys that do not need to function during the scroll mode of the hard keys installed around the screen, such as a detail key 102 and a wide area key for changing the scale of the map as shown in FIG. 104 or the like may be used in place of the scroll speed change icon 140.

That is, when the scroll direction designation icon 120 is displayed after the transition to the scroll mode, the detail key 102 is set as a function for increasing the scroll speed, and the wide area key 104 is set as a function for decreasing the scroll speed. To do.
In this way, a part of the map is not hidden by the icon display, and the operability can be improved.

  Also, as shown in FIG. 2, the scroll direction designation icon 120 and the scroll speed change icon 140 are displayed at the same time. However, the present invention is not limited to this, and the scroll speed change icon 140 is not displayed in the state where the scroll is not performed. When the scroll speed change icon 140 is displayed, the scroll speed change icon 140 is displayed so that a part of the map is not hidden by the scroll speed change icon 140.

Next, another embodiment of the present invention will be described with reference to FIG.
As in the first embodiment, as shown in FIG. 3, when an arbitrary place on the touch panel screen 100 is pressed with a finger while the vehicle position mark and the map around the vehicle position mark are displayed on the touch panel screen 100. Then, the touch sensor on the touch panel screen 100 sends a scroll request signal to the controller 43, and the controller 43 sends the scroll request signal to the CPU 11 via the internal bus 70 as a scroll interrupt signal for the CPU 11.

  Upon receiving this interrupt, the CPU 11 starts the touch panel interrupt processing shown in FIG. 7 and starts measuring the time during which the touch panel screen 100 is pressed by the timer built in the CPU 11 in S302, and the coordinate value at the center of the screen. The direction to be scrolled is specified from the coordinate value of the specified position.

  Therefore, in this embodiment, the time during which the touch panel screen 100 is pressed with a finger and the touch panel screen 100 may not be pressed anywhere. Therefore, it is necessary to designate a point in the direction in which the user wants to scroll for a predetermined time, and this may be explained by voice when starting up the instruction manual or the navigation device.

Then, in S304, it is monitored whether or not the finger is removed from the touch panel screen 100. If it is determined that the finger has been released (contact is released) ("Y"), the process proceeds to S306 and the contact time between the finger and the touch panel screen 100 is reached. Determines whether or not a predetermined time has passed.
Here, if the contact time between the finger and the touch panel screen 100 has not passed the predetermined time in the determination of S306, the process proceeds to S308 and scrolls until the point designated by the finger comes to the center of the screen of the touch panel screen 100 to register the point. Or other processing such as inquiries.

  In addition, when the contact time in S306 is equal to or longer than the predetermined time (in the case of “Y”), the process proceeds to S310, and the scroll speed change icon 140 is displayed on the touch panel screen 100 as shown in FIG. Later, the process proceeds to S312 to start scrolling the map screen in the direction designated by the finger first. Here, the scroll direction designation icon 120 is set not to be displayed.

  After that, it is monitored in S314 that the finger touches the touch panel screen 100 again. If touch of the finger on the touch panel screen 100 is detected (in the case of “Y”), the process proceeds to S316. If it is the scroll speed change icon 140 (in the case of “Y”), the process proceeds to S318 to update the scroll speed data and adjust the scroll speed.

  Here, as in FIG. 2, the scroll speed change icon 140 is given an attribute indicating an increase in scroll speed with an arrow in the upper direction of the screen, and conversely, an arrow in the lower direction on the screen is given an attribute indicating a decrease in the scroll speed. ing.

  When the scroll speed adjustment is executed in S318, the process returns to S314 to monitor the touch panel touch again, and increases again when the previous scroll speed adjustment is a request in the increasing direction as in the first embodiment. When the direction request is instructed by the scroll speed change icon 140, the scroll speed is further increased from the scroll speed at this time, and the map is scrolled. Conversely, when the adjustment of the scroll speed is a request in the decreasing direction, the scroll speed is decreased and the map is scrolled.

  On the other hand, if the scroll speed change icon 140 is not pressed in S316 (in the case of “N”), the process proceeds to S320 to immediately stop the scrolling of the map, and the display of the scroll speed change icon 140 is also stopped. Return to the process.

  By executing the process as described above, a new map scroll operation device that has a scroll mode that can easily change the scrolling speed can be scrolled without pressing the touch panel screen with a finger and continuing to specify. A navigation device can be provided.

  In the above-described second embodiment, when the time during which the touch panel is pressed does not reach the predetermined time, the pressed point is scrolled to the center of the screen and stopped. Although the scrolling is continued after that, it can be similarly implemented even if the relationship between the time during which the touch panel is pressed and the scrolling operation is reversed.
