Description

  The present invention relates to an input method, and more particularly to an input method that is employed in a navigation system or the like and that improves operability such as a scale changing operation of an image such as a map.

  The navigation system usually displays a map on the display screen, the destination input by the user on the map, the guidance route to the destination, the vehicle position mark corresponding to the current position of the vehicle, In addition, the user can obtain the route information by referring to this display screen one after the other and follow the route information. You can reach your destination. Moreover, the map display is equipped with a function for changing the scale so that the map can be freely enlarged or reduced. Thus, in the navigation system, a really excellent function is realized.

  However, even if an excellent function can be realized, if the operation is complicated or difficult, the value is reduced by half. By the way, the navigation system is conventionally operated by switch operation or menu selection, and the menu selection is performed by operation of a joystick or a touch panel provided on the display screen of the display. It has become.

  Since the touch panel can be operated simply by touching the display screen with a finger, it is possible to realize a very easy-to-use human interface. However, the conventional state is not sufficient, and further improvement is desired. . In particular, the display screens used in navigation systems are not very large compared to the display screens used in information devices such as personal computers. Was not good.

  In addition, the navigation system can be operated while the vehicle is running, or it can be operated in a short interval such as waiting for a signal. It is an important factor for improving the performance.

Means for solving the problems and their effects

  The present invention has been made in view of the above problems, and provides an input method capable of performing a flexible and easy input operation of functions such as enlargement or reduction of an image such as a map according to a user's intention. It is an object.

In order to achieve the above object, an input method ( 1 ) according to the present invention includes a step of detecting two instructed points in an input operation of a touch panel, and a point detection means that is not a point determined by the positions of the two points Based on a fixed point based on the vehicle position as a reference, a step of performing display rotation processing based on a movement situation between the two designated points detected by the step of detecting the two points, and a point determined by the position of the two points A rotation process based on a movement state between the two designated points detected by the step of detecting the two points with reference to a fixed point based on the center point of the image that is not, and the rotation process. The display is rotated by selecting one of the steps for performing the above.

According to the input method ( 1 ), when the step of rotating with reference to the fixed point based on the vehicle position is selected, two points designated on the touch panel are detected, and points determined by the positions of the two points Based on the fixed point based on the vehicle position from the position detection means that is not the reference, the display is rotated based on the detected movement state between the two points. For example, when the user rotates the other finger that is in contact with the touch panel with one finger that is in contact with the touch panel as the rotation axis (the operation is similar to that when using the compass) In the case), the movement between the two points on the basis of the fixed point based on the vehicle position from the position detection means that is not a point determined by the position of the two points, regardless of the position designated by these two fingers. The display can be rotated based on the situation (such as the rotation direction of the other finger). Therefore, the user does not lose sight of the vehicle position that has been viewed until now, that is, the user can predict the vehicle position of the image displayed before and after the change. Therefore, it is possible to perform display that is easy to use and easy to understand and in which the user can easily understand the position of the vehicle after the change.
In addition, when the step of rotating with reference to the fixed point based on the center point of the image is selected, two points designated on the touch panel are detected, and the center of the image that is not determined by the position of the two points is fixed. As a point, the display is rotated based on the detected movement state between the two points. For example, when the user rotates the other finger that is in contact with the touch panel with one finger that is in contact with the touch panel as the rotation axis (the operation is similar to that when using the compass) In other words, regardless of the position designated by these two fingers, the movement state between the two points (the other one) is set with the center of the image that is not determined by the position of the two points as a fixed point. The display can be rotated based on the rotation direction of the finger. Therefore, the user can operate anywhere on the touch panel without losing sight of the center of the image that has been viewed so far, that is, the image displayed after the change can be largely predicted from before the change. It is easy for the user to grasp the changed image, and it is possible to perform display that is easy to use and easy to understand, with the orientation of the image being changed.
In this way, as the fixed point when rotating the display, the vehicle position detected by the position detection means and the two types of fixed points at the center of the image can be used properly, and it is easy to use. Easy display.

The input method ( 2 ) according to the present invention is characterized in that, in the input method of (1), the display is a map.

According to the above input method ( 2 ), since the display is a map, the scale and orientation of the map can be changed with the fixed point as a reference, even if the display is different from that before the change. Because most of the map displayed before and after the change can be predicted, it is possible for the user to grasp the map contents after the change instantaneously, and the map scale and orientation that are easy to understand are changed. It can be performed.

  Embodiments of an input method according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram schematically showing a main part of a navigation system employing the input method according to the embodiment (1).

  A vehicle speed sensor 2 for calculating the travel distance by calculating from the vehicle speed and a gyro sensor 3 for acquiring the traveling direction are connected to the microcomputer 1, and the microcomputer 1 determines the calculated traveling distance and the traveling direction. Based on this, the vehicle position is determined (autonomous navigation).

  The GPS receiver 4 receives a GPS signal from a satellite via an antenna 5 and is connected to the microcomputer 1, and the microcomputer 1 determines the position of the vehicle based on the GPS signal. (GPS navigation).

  Further, a DVD drive 6 capable of fetching road data from a DVD-ROM 7 (which can be a large-capacity storage device such as a CD-ROM) in which road data is stored is connected to the microcomputer 1. By matching the determined vehicle position and road data (so-called map matching processing), a map showing the vehicle position accurately is displayed on the display screen 9b.

  In addition, a switch signal output from the joystick 8a or the button switch 8b provided on the remote controller 8 or a switch signal output from the button switch 9a provided on the display device 9 is input to the microcomputer 1 in accordance with these switch signals. The processing is performed by the microcomputer 1. For example, when the microcomputer 1 takes in the information of the moving destination from these switches, the microcomputer 1 searches for the optimum route from the vehicle position to the destination, and displays this as a guidance route on the display screen 9b together with the map. Yes.

  In this way, in the navigation device, the map is displayed on the display screen 9b, the destination input by the user on the map, the route to the destination, the vehicle position mark corresponding to the current position of the vehicle, and The traveling track of the vehicle until then is displayed in a superimposed manner, and the user can obtain the route information by sequentially referring to this display screen 9b, and by following the route information You can reach your destination.

  In the figure, reference numeral 10 denotes a contact detection means 10 for detecting physical contact with the display screen 9b. The contact detection means 10 is used when the user enlarges or reduces an image such as a map image, rotates, scrolls, etc. This is for detecting a finger or the like touched on the display screen 9b on which an image is displayed in order to input an operation, and is configured by laminating a transparent touch panel or the like on the display screen 9b. Further, the data detected by the contact detection means 10 is input to the microcomputer 1.

  Further, in the navigation system employing the input method according to the embodiment (1), the user can make various settings through the screen displayed on the display screen 9b. As shown in FIG. -When the operation of moving the two fingers in contact with the display screen 9b on which the map image is displayed is performed through the "setting of reduction" screen, the image is enlarged or reduced, or on the other hand, the two fingers The image can be enlarged or reduced through the setting of whether to reduce or enlarge the image when the image is moved closer, and the “fixed point setting (enlargement / reduction)” screen as shown in FIG. It is possible to make a setting such as setting any one of the following 1 to 4 as a fixed point.

1 “Center of image”
As shown in FIG. 4A, the center point of the image is the same as the center point a of the display screen 9b when the image is displayed on the full screen of the display screen 9b. As shown in (), when the image is not fully displayed on the display screen 9b, the point b is obtained.
2 "Vehicle position mark display point"
The display point of the own vehicle position mark is a point where the own vehicle position mark M represented by a black triangle is displayed as shown in FIGS. 4 (a) and 4 (b).

3.1 “Left end”
Of the points where two fingers are first brought into contact with the display screen 9b (that is, the contact points before the start of movement), this is the point closest to the left end of the display screen 9b. For example, as shown in FIG. When an operation is performed using the thumb and index finger of the right hand, the point c touched by the thumb is a fixed point.
3.2 “Right end”
Among points where two fingers are first brought into contact with the display screen 9b, the point closest to the right end of the display screen 9b is operated using, for example, the thumb and index finger of the right hand as shown in FIG. In this case, the point d touched with the index finger becomes a fixed point.
3.3 “Top”
Among points where two fingers are first brought into contact with the display screen 9b, the point closest to the right end of the display screen 9b is operated using, for example, the thumb and index finger of the right hand as shown in FIG. In this case, the point d touched with the index finger becomes a fixed point.
3.4 “Bottom”
Among points where two fingers are first brought into contact with the display screen 9b, the point closest to the right end of the display screen 9b is operated using, for example, the thumb and index finger of the right hand as shown in FIG. In this case, the point c touched by the thumb becomes a fixed point.

4 “Midpoint between two points”
This is an intermediate point between the points where two fingers first contact the display screen 9b. For example, as shown in FIG. 5, when operating with the thumb and index finger of the right hand, the contact with the thumb The middle point e of the line segment connecting the point and the contact point with the index finger is a fixed point.

  Further, through the “fixed point setting (rotational movement)” screen as shown in FIG. 6, the fixed point when rotating the image (that is, when changing the display direction of the image) is set to any of the following 1-3. You can make settings such as

1 “Image center point” (see Figure 4)
2 “Vehicle position mark display point” (see Figure 4)
3 “Rotating shaft”
The point of contact with the display screen 9b as the rotation axis. For example, as shown in FIGS. 7A and 7B, the thumb and index finger of the right hand are used, and the index finger is rotated around the thumb as the rotation axis. When moving (point g → point g ′), the contact point f with the thumb becomes a fixed point.

  Next, the processing operation (1) performed by the microcomputer 1 in the navigation system employing the input method according to the embodiment (1) will be described based on the flowcharts shown in FIGS.

  First, it is determined whether or not there has been a physical contact with the touch panel, that is, whether or not there has been a finger contact with the touch panel (step S1). End 1). On the other hand, if it is determined that a finger touches the touch panel, the timer t is started (step S2).

  Next, after the timer t is started, it is determined whether or not there are two or more touch points on the touch panel (step S3). If it is determined that there are two or more touch points, that is, only one point, the touch point moves. If it is determined whether or not the contact point is moving (that is, the finger is moved on the display screen 9b), whether or not the movement is a linear movement ( That is, it is determined whether or not the movement of the finger is a linear movement (step S5), and if it is determined that the movement is a linear movement (see FIG. 11), the display screen 9b is displayed in accordance with the movement direction. A scroll process is performed on the displayed image (step S6).

  On the other hand, if it is determined in step S5 that the movement is not a linear movement, it is determined whether or not the movement is a rotational movement (that is, whether or not the movement of the finger is a rotational movement) (step S1). S7) If it is determined that the movement is a rotational movement (see FIG. 12), it is determined whether the rotation direction is clockwise (step S8), and if it is determined that the rotation direction is clockwise, An enlargement process is performed on the image displayed on the display screen 9b (step S9), and if it is determined that the rotation direction is counterclockwise, a reduction process is performed on the image displayed on the display screen 9b. (Step S10). On the other hand, if it is determined in step S7 that the movement is not a rotational movement, the processing operation (1) is terminated.

  If it is determined in the determination process in step S4 that the contact point has not moved (that is, the finger is not moved on the display screen 9), whether or not the touch to the touch panel is lost, that is, the touch panel 9b is displayed. It is determined whether or not the touched finger has been released from the touch panel 9b (step S11). If it is determined that the finger has been released from the touch panel, it is determined whether or not there has been re-contact with the touch panel at substantially the same point (step S11). S12).

If it is determined that there is no re-contact with the touch panel, it is determined whether or not the timer t has elapsed a predetermined time t ₁ (for example, 1 second) (step S13), and the timer t has elapsed the predetermined time t ₁ . If it is determined that the number of times of contact within the predetermined time t ₁ is one, reduction processing is performed on the image displayed on the display screen 9b (step S14). On the other hand, if the timer t determines that the predetermined time t ₁ has not elapsed, the process returns to step S12.

On the other hand, in the determination processing in step S12, there is a physical re-contact to the touch panel, i.e., it is judged that there is a contact twice in a predetermined time t ₁ (user was continuously touching the touch panel) For example, the image displayed on the display screen 9b is enlarged (step S15).

Further, in the determination process in step S11, it is judged that the finger from the touch panel is not separated, the timer t is determined whether the predetermined time t ₁ has elapsed (step S16), and the timer t is the predetermined time t ₁ has elapsed if to have a judgment, subjected to reduction processing for the image displayed on the display screen 9b (step S14), and on the other hand, when it is judged that the timer t is not the predetermined time t ₁ has elapsed, the step S11 Return.

  By the way, if it is determined in step S3 that there are two or more touch points on the touch panel (that is, two fingers are touching the touch panel), a change in distance between the two points is calculated (step S21) It is determined whether or not the distance between the two points is long (step S22). The distance between the two points is long (that is, the user performs an operation of moving two fingers away). If it is determined that the enlargement process or the reduction process (the process in the subsequent step S24) is performed based on the contents set through the “fixed point setting (enlargement / reduction)” screen (see FIG. 3). The fixed point is calculated (step S23).

  Next, an enlargement process or a reduction process is performed on the image displayed on the display screen 9b based on the contents set through the “enlargement / reduction setting” screen (see FIG. 2) (step S24). . At this time, image processing is performed so as to fix the fixed point calculated in step S23.

  On the other hand, if it is determined in step S22 that the distance between the two points is not long, it is next determined whether or not the distance between the two points is short (step S25). If it is determined that the distance is short (ie, the user is moving two fingers closer), the setting is made through the “fixed point setting (enlargement / reduction)” screen (see FIG. 3). Based on the contents, a fixed point for performing the enlargement process or the reduction process (the process in the subsequent step S27) is calculated (step S26).

  Next, an enlargement process or a reduction process is performed on the image displayed on the display screen 9b based on the contents set through the “enlargement / reduction setting” screen (see FIG. 2) (step S27). . At this time, image processing is performed so as to fix the fixed point calculated in step S26.

  If it is determined in the determination process in step S25 that the distance between the two points is not shortened, it is next determined whether or not the other contact point is rotationally moved with the one contact point as the rotation axis (step S25). S28) If it is determined that it is rotating, based on the contents set through the “fixed point setting (rotating movement)” screen (see FIG. 6), the rotation process (the process in the subsequent step S30) is performed. A fixed point at the time of calculation is calculated (step S29). Next, a process of changing the orientation of the image displayed on the display screen 9b according to the direction of the rotational movement is performed so as to fix the calculated fixed point (step S30).

  In the navigation system that employs the input method according to the above embodiment (1), when a clockwise rotation operation with one finger is detected, an enlargement process is performed (refer to step S9). When a rotation operation is detected, a reduction process is performed (step S10). However, in another embodiment, when a clockwise rotation operation is detected, a reduction process is performed and a counterclockwise rotation is performed. When a rotation operation is detected, an enlargement process may be performed. Furthermore, in the input method according to another embodiment, the user can freely select these processes through the screen as shown in FIG. 13, and the microcomputer 1 performs the enlargement process and the reduction process through the screen. Anyway.

  Further, in the navigation system employing the input method according to the above embodiment (1), when one touch operation with one finger is detected, a reduction process is performed (see step S14), and continuous with one finger. When a touch operation is detected, an enlargement process is performed (see step S15). However, in another embodiment, when a one-touch operation is detected, an enlargement process is performed and a continuous touch operation is detected. Then, reduction processing may be performed. Furthermore, in the input method according to another embodiment, the user can freely select these processes through the screen as shown in FIG. 14, and the microcomputer 1 performs the enlargement process and the reduction process through the screen. Anyway.

  In addition, in the navigation system employing the input method according to the above embodiment (1), when an operation of moving two fingers away or an operation of moving them closer is detected, an enlargement process and a reduction process (see steps S24 and S27) are performed. However, in another embodiment, the present invention is not limited to two fingers. For example, when an operation of moving three fingers away or an operation of moving them closer is detected, enlargement processing or reduction processing is performed. You may do it.

  In addition, as a method for determining whether or not three fingers are moving away (or approaching), for example, the center of gravity of a triangle composed of three contact points is obtained and moved away from the center of gravity (or There is a method for determining whether or not the finger is moving in the direction of approaching.

If it is determined that the navigation route is not in the guidance route setting mode, the processing operation ( If it is determined that the guidance route setting mode has been completed, it is determined whether or not there is a physical contact with the touch panel, that is, whether or not a finger touches the touch panel (step S32). ).

  If it is determined that there is no finger contact with the touch panel, the processing operation (2) is terminated, and if it is determined that there is a finger contact with the touch panel, the timer t is started (step S33). After the timer t is started, it is determined whether or not the touch on the touch panel has been lost, that is, whether or not the finger touching the touch panel has been released from the touch panel (step S34). It is determined whether or not there has been re-contact with the touch panel at substantially the same point (step S35).

If it is determined that there is no re-contact with the touch panel, it is determined whether or not the timer t has elapsed a predetermined time t ₂ (eg, 1 second) (step S36), and the timer t has elapsed the predetermined time t ₂ . If it is determined that the number of times of contact within the predetermined time t ₂ is one, the processing operation (2) is terminated as it is. On the other hand, if the timer t determines that the predetermined time t ₂ has not elapsed, the process returns to step S35.

On the other hand, in the determination processing in step S35, there is a physical re-contact to the touch panel, i.e., it is judged that there is a contact twice in a predetermined time t in ₂ (user was continuously touching the touch panel) For example, the point of the map image displayed on the display screen 9b corresponding to the contact point is set as the destination for calculating the guidance route (step S37).

Further, in the determination process in step S34, if it is determined that no remote finger from the touch panel, the timer t is determined whether predetermined time has elapsed t ₃ (e.g., 1 second) (step S38), the timer t If the predetermined time t _{3 has} elapsed, that is, it is determined that the touch panel has been pressed for a long time, the map route corresponding to the contact point on the map image displayed on the display screen 9b is calculated in calculating the guidance route. A relay point is set (step S39). On the other hand, if the timer t determines that the predetermined time t ₃ has not elapsed, the process returns to step S34.

  In the navigation system employing the input method according to the embodiment (2), when a continuous touch operation with one finger is detected, a destination is set (see step S37), and a long press operation is detected. Then, a relay point is set (see step S39). However, in another embodiment, when a continuous touch operation is detected, a relay point is set and a long press operation is detected. The destination may be set. Furthermore, in the input method according to another embodiment, the user can freely select these processes through the screen as shown in FIG. 16, and the microcomputer 1 performs the enlargement process and the reduction process through the screen.

  Next, the processing operation (3) performed by the microcomputer 1B in the navigation system adopting the input method according to the embodiment (3) will be described based on the flowchart shown in FIG.

  First, it is determined whether or not an operation with the remote controller 8 has been performed (step S41). If it is determined that an operation with the remote controller 8 has been performed, a support image is displayed so as to obtain a screen as shown in FIG. p is deleted from the screen (step S42). On the other hand, if it is determined that the operation using the remote controller 8 is not performed, it is determined whether or not the operation using the button switch 9a provided in the display device 9 is performed (step S43).

  If it is determined that the operation using the button switch 9a provided in the display device 9 has been performed, the support image p is erased from the screen so as to obtain a screen as shown in FIG. 17B (step S42). . On the other hand, if it is determined that the operation by the button switch 9a provided in the display device 9 is not performed, the processing operation (3) is ended as it is.

  When the support image p is displayed on the display screen 9b, a space for displaying a main image (for example, a map image) is reduced. However, the navigation system adopting the input method according to the embodiment (3) is used. Therefore, when the operation by the remote controller 8 or the operation by the button switch 9a provided in the display device 9 is performed, the support screen p is deleted, so that the main image (for example, a map image) can be easily viewed. it can.

  As described above, in the input methods according to the embodiments (1) to (3), the case where the map is adopted in the navigation system and the map is enlarged or reduced as the user intends has been described.
