The processing execution part executes the pattern input processing in preference to the projection assigned processing if the input pattern meets with a reference pattern.

Description

  The present invention relates to an input system including an input device such as a touch pad.

  For example, in a notebook personal computer or the like, a device equipped with an input system including an input device such as a touch pad is used. The user moves the operation cursor displayed on the display screen by sliding the fingertip or the like on the detection surface provided on the touch pad surface. Further, for example, a function associated with the operation mark is realized by performing a predetermined operation on the detection surface in a state where the operation cursor displayed on the display screen is set to an operation mark (for example, a button or an icon). Such an input system can also be used for inputting a predetermined operation to the navigation system.

  By the way, the navigation system is often operated by a vehicle driver. In such a case, since the user (vehicle driver) operates the navigation device between driving, it is difficult to perform the operation while paying attention to the display screen, and the desired operation can be performed accurately. There are cases where it is not possible. In view of such a point, an input system has been proposed in which operation input can be performed without using a tactile sensation (tactile sensation) without gazing at a display screen. For example, in Japanese Patent Application Laid-Open No. 2006-268068 (Patent Document 1), the entire detection surface is covered with fiber hair, and the fiber hair at the position of the detection surface corresponding to the position of the operation mark displayed on the display device is raised. Technology is disclosed.

  In the system of Patent Document 1, the detection surface area that makes the tactile sensation different by raising fiber hairs or the like is the display area of the operation mark on the display screen (Embodiment 1 to 3 or the like) or the display of the operation mark. The area is limited to the area (Embodiment 4) associated with the area according to a predetermined rule. However, when a system that mainly displays a map image on the display screen, such as a navigation system, is a target of operation input, the tactile sensation is different even in the detection surface area corresponding to the area other than the display area of the operation mark. It may be preferable from the viewpoint of convenience.

  Further, in an input system including an input device such as a touch pad, for example, as disclosed in Japanese Patent Application Publication No. 2010-541071 (Patent Document 2), input by simultaneous detection of a plurality of detection objects on a detection surface (so-called multi-touch) Some of them are known to be capable of input). In such a system, various processes according to input patterns by a plurality of detection objects detected on the detection surface are executed. By the way, when the input system of patent document 1 is comprised so that multi-touch input is possible, when a user touches the detection surface area | region where the fiber hair was raised as a result of performing multi-touch, two operation inputs will compete. Will do. In such a case, it is desired to appropriately handle two competing operation inputs and to smoothly execute the resulting processing. With respect to these points, no consideration has been given to the systems of Patent Document 1 and Patent Document 2.

  Therefore, it is possible to perform an operation input without paying attention to the display screen, and it is excellent in convenience when a map image is displayed on the display screen, and can perform various processes smoothly. Realization of the system is desired.

  The characteristic configuration of the input system according to the present invention includes a display device capable of displaying various images on a display screen, a detection surface for detecting a detection object to be contacted, and a predetermined rule along the detection surface. When a map image is displayed on the display screen, an input device having a plurality of projecting members provided so as to be able to project independently from the detection surface, and the projecting member is associated with the map image. A process is assigned to each of the projecting control unit configured to project and the projecting member in the projecting state, and the operation is performed when it is detected that the projecting member is operated by the detected object. Protrusion assignment processing, which is processing assigned to the projecting member, can be executed, and input patterns by the plurality of detected objects detected on the detection surface match a predetermined reference pattern. A process execution unit capable of executing a pattern input process that is a process according to the input pattern, and the process execution unit projects the protrusion when the input pattern matches the reference pattern. Even when it is detected that a member has been operated, the pattern input process is executed without executing the protrusion assignment process.

  According to this characteristic configuration, the protruding member that is in a protruding state corresponding to the map image displayed on the display screen can be directly tactilely recognized by a fingertip or the like. Then, after the tactile recognition of the projecting member in the projecting state, the projecting assignment process assigned to the projecting member can be executed by operating the specific projecting member with a fingertip or the like. For this reason, the user can easily perform a desired operation input according to the displayed map image without relying only on vision. In addition, the user can also execute pattern input processing corresponding to input patterns by a plurality of detected objects detected on the detection surface by operating the detection surface with a plurality of fingertips or the like. In this case, when the input pattern by a plurality of objects to be detected matches the reference pattern, the pattern input process is preferentially executed with respect to the protrusion assignment process. Therefore, even when the protrusion assignment process and the pattern input process compete, the entire process can be smoothly executed.

  Here, it is preferable that the process execution unit executes the protrusion assignment process when it is detected that the input pattern does not match the reference pattern and the protrusion member is operated.

  When the input pattern by a plurality of detected objects does not match the reference pattern, the pattern input process is not preferentially executed, so the protrusion assignment process is performed depending on whether or not the protruding member is detected. It is sufficient to determine whether or not execution is possible. In view of this point, according to this configuration, it is possible to appropriately execute the protrusion assignment process according to the situation.

  Further, in the reference pattern, the detection position on the detection surface of at least one of the plurality of detection objects moves, and the relative positional relationship of the detection positions on the detection surface of the plurality of detection objects changes. A pattern is preferred.

  When the detection positions of a plurality of detection objects move and their relative positional relationship is kept substantially constant, the user operates the detection surface with other fingertips etc. in contact with the detection surface. It is estimated that there is a possibility that the detection surface is operated with a plurality of fingertips unintentionally. On the other hand, when the relative positional relationship of a plurality of objects to be detected changes, it is estimated that the user is likely to operate the detection surface with a plurality of fingertips or the like with some intention. According to this configuration, it is possible to select only the input patterns that are estimated to reflect the user's intention and to execute the corresponding pattern input process.

  Further, the protrusion control unit causes the protruding member to protrude corresponding to a road included in the map image, and the processing execution unit uses attribute information that defines an attribute of the road corresponding to each of the protruding members. It is preferable that the different projecting assignment process is assigned to each projecting member.

  According to this configuration, the user can operate the projecting assignment process according to the attribute information of the road corresponding to the projecting member only by operating the projecting member that is projected in correspondence with the road included in the map image. Can be executed. Therefore, the convenience for the user can be improved, and the display screen is also watched when executing the projecting assignment process according to the attribute information of each road included in the map image displayed on the display screen. It is possible to perform operation input without any problem.

  The map image is an image of a map for navigation including a self-position image indicating the self-position determined by the self-position determination unit, and the attribute information constitutes a guide route from the departure place to the destination. Including at least one of a route attribute indicating whether or not a road and a positional attribute indicating a positional relationship with the own position on each road constituting the guide route, the processing execution unit, Depending on the route attribute, and when the route attribute indicates that the road constitutes the guide route, the different projection assignment process is assigned to each of the projecting members according to the position attribute. It is preferable.

  According to this configuration, the user can execute different protrusion assignment processes depending on whether the road corresponding to the operated protrusion member is a road constituting a guide route or a road other than that. In addition, the user can determine whether the road constituting the guide route is his / her own location, a location on the guide route from his / her location to the destination, or a location on the guide route from the departure location to his / her location. Depending on whether or not there is a different protrusion assignment process. Therefore, it is possible to appropriately execute necessary processing according to road attributes that are important information in navigation without paying attention to the display screen.

In the present embodiment, the protruding status includes a “protruding state” and a “non-projecting state”. The “protruding state” includes a “high protruding state” and a “low protruding state”. Here, the “non-projection state” as one of the projecting statuses is a state in which the projecting member 20 is at the minimum displacement position within the movable range in the projecting direction Z (the tip portion of the pin member 21 is the detection surface). 11a). The “high projecting state” is a state in which the projecting member 20 is at the maximum displacement position within the movable range in the projecting direction Z. The “low protrusion state” is a state between the “high protrusion state” and the “non-protrusion state”, and is an intermediate state in this example. In the present embodiment, the status determination unit 52 alternatively determines whether each protruding member 20 is in a high protruding state, a low protruding state, or a non-projecting state.

  In the present embodiment, the map image displayed on the display screen 41 is a map image for navigation, and a map image around the own position, an image of the own position mark P, an image of the operation mark 44, and the like can be displayed. . When the image including the road S constituting the guide route is displayed on the display screen 41, the status determination unit 52 sets the protruding status to “high protruding state” for the plurality of protruding members 20 corresponding to the road S. judge. Further, when an image including a road T other than the road S constituting the guide route is displayed on the display screen 41, the status determination unit 52 displays the protrusion status of the plurality of protruding members 20 corresponding to the road T. Determined as “low protrusion”. In the present embodiment, the status determination unit 52 associates the coordinates of the display screen 41 with the coordinates of the detection surface 11a, and corresponds to the coordinates of each point included in the trajectory representing each of the displayed road S and road T. With respect to the plurality of projecting members 20 located at the coordinates of each point on the detection surface 11a, the projecting status is determined as “high projecting state” and “low projecting state”, respectively.

  In addition, when an image including the own position mark P is displayed on the display screen 41, the status determination unit 52 determines that the protruding status of the protruding member 20 corresponding to the own position mark P is “high protruding state”. To do. Further, when an image including a specific facility (landmark) Q having a characteristic to be a landmark is displayed on the display screen 41, the status determination unit 52 projects the protruding member 20 corresponding to the specific facility Q. The status is determined as “high protruding state”. Furthermore, when an image including a specific operation mark 44 is displayed on the display screen 41, the status determination unit 52 sets the protrusion status of the protrusion member 20 corresponding to the coordinates of the operation mark 44 to “low protrusion state”. Is determined. In the present embodiment, the status determination unit 52 associates the coordinates of the display screen 41 with the coordinates of the detection surface 11a, and corresponds to the coordinates of the displayed self-location mark P, specific facility Q, and operation mark 44. The one or more projecting members 20 located at the coordinates on the detection surface 11a to be detected are determined to have a projecting status of “high projecting state” or “low projecting state”.

  In addition, the status determination part 52 is about the protrusion member 20 corresponding to each point of the area | region where none of the road R, the own position mark P, and the operation mark 44 is displayed in the image displayed on the display screen 41. The protrusion status is determined as “non-projection state”.

  The status determination unit 52 outputs information on the protrusion status determined for each of the protruding members 20 to the protrusion control unit 53.

  The protrusion control unit 53 controls the protruding state of each of the protruding members 20 in accordance with the image content displayed on the display screen 41. When the map image is displayed on the display screen 41, the protrusion control unit 53 sets the protruding member 20 in a protruding state corresponding to the map image. The protrusion control part 53 controls the drive mechanism 30 based on the information received from the status determination part 52, and controls the position of the protrusion direction Z of the protrusion member 20 with respect to the detection surface 11a. In the present embodiment, the protrusion control unit 53 sets the protruding member 20 in a protruding state corresponding to the road R, the specific facility Q, the own position mark P, and the operation mark 44. Here, the coordinates of the display screen 41 and the coordinates of the detection surface 11a are associated with each other. Therefore, the protrusion control unit 53 is arranged at the position of the coordinates of the detection surface 11a associated with the coordinates of the road R, the specific facility Q, the own position mark P, and the operation mark 44 on the display screen 41. 20 can be projected.

  In the present embodiment, the protruding member 20 corresponding to the road S constituting the guide route in the road R is protruded so that the protruding amount is larger than the protruding members 20 corresponding to the other roads T. Further, the protruding member 20 corresponding to the own position mark P or the specific facility Q is also protruded so that the protruding amount is larger than the protruding member 20 corresponding to the road T other than the road S constituting the guide route. Further, the protruding member 20 corresponding to the operation mark 44 is protruded so that the protruding amount is smaller than the protruding member 20 corresponding to the road S, the own position mark P, and the specific facility Q constituting the guide route. In the present embodiment, the protrusion control unit 53 sets the protruding member 20 corresponding to the road S, the own position mark P, and the specific facility Q that constitute the guide route to the “highly protruding state”, and other than the road S that constitutes the guide route. The protruding member 20 corresponding to the road T and the operation mark 44 is set to the “low protruding state”.

  The protrusion control unit 53 sets the protrusion member 20 corresponding to an area (for example, a background or the like) where none of the road R, the specific facility Q, the own position mark P, and the operation mark 44 is displayed as a “non-protruding state”. (See FIG. 4).

  When changing the protruding state of the protruding member 20, the protrusion control unit 53 applies a pulse voltage to the piezoelectric element 31 corresponding to each protruding member 20 to vibrate the piezoelectric element 31. At this time, the protrusion control unit 53 is configured to be able to adjust the magnitude relationship between the vibration speed toward one side and the vibration speed toward the other side along the protrusion direction Z. Such a configuration can be realized by changing the duty ratio according to the vibration direction of the piezoelectric element 31. The protrusion control part 53 moves the protrusion member 20 to the protrusion direction side by making the vibration speed to the protrusion direction side smaller than the vibration speed to the burying direction side. On the other hand, the protrusion control part 53 moves the protrusion member 20 to the burying direction side by making the vibration speed to the burying direction side smaller than the vibration speed to the protrusion direction side.

  With the movement of the own position, the protrusion control unit 53 updates the protruding state of the protruding member 20 in accordance with the change in the positional relationship between the own position and the map. With the movement of the own position, the map image displayed on the display screen 41 is updated, and the form of the displayed road R also changes every moment. The protrusion control unit 53 updates the protrusion state of the protrusion member 20 on the detection surface 11a in accordance with the form of the road R that changes every moment (see FIG. 6). The protrusion control unit 53 updates the protrusion state of the protrusion member 20 so that the protrusion state of the protrusion member 20 follows the map displayed on the display screen 41.

  The position detection unit 54 acquires the detection position of the detection object D on the detection surface 11 a of the touch pad 10. The position detection unit 54 specifies the position of the electrode that the detected object D is closest to based on the change in capacitance between the electrodes that occurs when a fingertip or the like as the detected object D contacts the detection surface 11a. To do. And the position detection part 54 acquires the position of the specified electrode as a detection position in the detection surface 11a. With such a function of the position detection unit 54, the touch pad 10 can accept an input corresponding to a detection position on the detection surface 11a. In addition, when the some to-be-detected object D is contacting the detection surface 11a simultaneously, the input according to each detection position can also be received. That is, the touch pad 10 according to the present embodiment is configured to allow so-called multi-touch input. The position detection unit 54 outputs the acquired detection position information to the drawing control unit 51 and the operation determination unit 56.

  The state detection unit 55 detects the “high protrusion state”, the “low protrusion state”, and the “non-protrusion state” of the protrusion member 20 in a distinguishable manner. The state detection unit 55 is configured to be able to acquire information from, for example, a position sensor (not shown). Based on the acquired position information of each projecting member 20 in the projecting direction Z, the state detection unit 55 determines that the actual projecting status of each projecting member 20 is “high projecting state”, “low projecting state”, and “non-projecting state”. It is detected whether it is in the “projection state”. The state detection unit 55 outputs information on the detection result to the operation determination unit 56.

  The operation determination unit 56 determines an operation input to the navigation device 1 by the user based on at least a specific operation on the detection surface 11a. In the present embodiment, the “specific operation” serving as the determination criterion can include, for example, a touch operation, a tap operation, a slide operation (race operation), a pinch-out operation, a pinch-in operation, and the like. The touch operation is an operation of bringing the detection object D that is not in contact with the detection surface 11a into contact with the detection surface 11a. The tap operation is an operation in which the detection object D that is in contact with the detection surface 11a is once brought up from the detection surface 11a and then brought into contact again. This tap operation includes a double tap operation in which the tap operation is repeated twice within a predetermined time. The slide operation is an operation of moving (tracing) the detection object D in contact with the detection surface 11a along the detection surface 11a. The pinch-out operation is an operation of relatively moving a plurality of detection objects D that are in contact with the detection surface 11a away from each other. The pinch-in operation is an operation of relatively moving the plurality of detection objects D that are in contact with the detection surface 11a so as to approach each other.

  Further, in the present embodiment, such “specific operation” may include a pushing operation and a separation operation with respect to the protruding member 20. The pushing operation is an operation of pushing the protruding member 20 in the protruding state toward the detection surface 11a. The separation operation is an operation in which the detection object D is separated from the detection surface 11a after the touch operation or the slide operation. Among these operations, touch operation, tap operation, double tap operation, push-in operation, and separation operation are included in the single touch operation, and pinch operations (pinch-out operation and pinch-in operation) are included in the multi-touch operation.

  The operation determination unit 56 determines an operation input to the navigation device 1 by the user based on the specific operation performed on the detection surface 11a. As such operation input, for example, selection of a specific point in a map displayed on the display screen 41 by a single touch operation, selection of a specific function associated with the operation mark 44, or display by a multi-touch operation is performed. Examples include changing the scale of the map displayed on the screen 41 (enlarging or reducing). For a single touch operation, the operation determination unit 56 determines the presence or absence of an operation input based on the position of the detection surface 11a where the single touch operation is performed. Furthermore, in this embodiment, the operation determination part 56 determines the presence or absence of operation input based on the detection position, when the separation operation as single touch operation is made.

  In addition, the operation determination unit 56 determines that the multi-touch operation is performed by the user based on only the multi-touch operation performed regardless of the position of the detection surface 11a on which the multi-touch operation has been performed. An operation input to the navigation device 1 can also be determined. In the present embodiment, both the separation operation and the pinch operation are “specific operations” that are determination criteria for the operation input to the navigation device 1. When the operation determination unit 56 detects that a specific operation (separation operation or pinch operation in this example) has been performed on the detection surface 11 a, the operation determination unit 56 outputs information indicating that to the processing execution unit 57.

  The process execution unit 57 executes a process based on the determination result by the operation determination unit 56. In the present embodiment, the process execution unit 57 is configured to be able to execute the projecting assignment process and the pattern input process. The projecting assignment process is assigned to each projecting member 20 in the projecting state, and when it is detected that the projecting member 20 has been operated by the object D to be detected (separation operation in this example), the projecting projecting operation is performed. This process is executed according to the member 20. The pattern input process is a process executed according to an input pattern when input patterns by the plurality of detection objects D detected on the detection surface 11a match a predetermined reference pattern. Here, the “reference pattern” has a relative positional relationship between the detection positions of the plurality of detection objects D on the detection surface 11a by moving the detection positions of at least one detection surface 11a of the detection objects D. It is a changing pattern. In this example, the input pattern by the pinch operation is an input pattern that matches this reference pattern.

  When the separation operation is performed on the projecting member 20 that is in a projecting state corresponding to the road R on the map, the specific facility Q, the own position mark P, and the operation mark 44, the processing execution unit 57 is separated. The protrusion assignment process assigned to the protruding member 20 that has been operated is executed. In this embodiment, the process execution part 57 performs the protrusion allocation process allocated to the protrusion member 20 in which the said separation operation was made, when such a separation operation is determined after a slide operation. That is, when the process execution unit 57 detects that the detected object D has moved away from the detection surface 11a at the position of the protruding member 20 that has been in the protruding state after moving along the detection surface 11a, the processing execution unit 57 The protrusion assignment process assigned to the protruding member 20 at the position where this is detected (the protrusion assignment process assigned to the protruding member 20 that has been contacted last) is executed. At this time, in the present embodiment, the projecting member 20 that is first contacted (or the position where the detection object D is first detected on the detection surface 11a), or the projecting member 20 that is contacted in the middle stage (or detection). The position where the detection object D is detected in the middle of the surface 11a is not a problem. In other words, the process execution unit 57 pays attention only to the projecting member 20 that is contacted last, and executes the process assigned to the projecting member 20.

  Here, the process execution unit 57 assigns different processes to each of the protruding members 20 according to the road R on the map, the specific facility Q, and the own position mark P. For the road R, the process execution unit 57 assigns different processes to the projecting members 20 according to attribute information that defines the attributes of the road R corresponding to the projecting members 20. The attribute information of the road R includes at least one information of a route attribute and a position attribute. The route attribute is whether or not the road constitutes a guide route from the departure point to the destination (whether the road constitutes the guide route from the departure point to the destination or a road other than the road constituting the guide route) Attribute). The position attribute is the positional relationship with the own position on each road that constitutes the guide route (the position on the guide route from the starting point to the own position, whether it is the own position, or the guide from the own position to the destination) This is an attribute indicating whether the position is on the route.

  The process execution unit 57 assigns different processes to the projecting members 20 that are in a projecting state corresponding to the road R according to the respective attributes. That is, the process execution unit 57 assigns a different process to each of the projecting members 20 according to the route attribute (depending on whether the road constitutes the guide route). In addition, when the route attribute indicates that the road constitutes the guide route, the process execution unit 57 further determines the positional relationship with the own position on each road constituting the guide route. A different process is assigned to each of the protruding members 20.

  In the present embodiment, the process execution unit 57 resets the guide route to the projecting member 20 corresponding to the road T other than the road S constituting the guide route so as to pass the position corresponding to the projecting member 20. Assign configuration processing. FIG. 7 shows an example of this route resetting process. When it is detected that the projecting member 20 corresponding to the road T other than the road S constituting the guide route has been operated to be separated, the process execution unit 57 performs the route reassignment assigned to the separated projecting member 20. Execute the setting process. When it is detected that the object D has moved along the detection surface 11a and then moved away from the detection surface 11a at the position of the protruding member 20 corresponding to the road T, the protrusion member 20 is in a low protruding state. The part 57 resets the guide route so as to pass through a position corresponding to the projecting member 20 that is finally contacted. When the guide route is reset, the image displayed on the display screen 41 is updated accordingly, and the protruding state of each protruding member 20 is also updated.

  Further, the process execution unit 57 assigns a matching process (in this case, a forced matching process or a rematching process) to the protruding member 20 corresponding to its own position. Here, the compulsory matching process is a process for forcibly correcting a road whose own position is matched. The rematching process is a process of performing recalculation of roads that match their positions based on the latest information at that time. When it is detected that the projecting member 20 corresponding to the own position mark P has been separated, the process execution unit 57 is within a predetermined distance with respect to the road whose own position is matched at that time. Check if there are parallel roads. When there is a parallel road, the process execution unit 57 executes a forced matching process to match the position with the parallel road. When there is no parallel road, the process execution unit 57 executes a rematching process.

  FIG. 8 shows an example of forced matching processing. In FIG. 8, parallel roads U are parallel to each other within a predetermined distance with respect to a road whose own position is matched (a road S constituting the guide route). When it is detected that the protruding member 20 corresponding to the own position mark P is separated, the process execution unit 57 is a process assigned to the separated member 20 (forced matching process in this example). Execute. When it is detected that the detection object D moves along the detection surface 11a and then moves away from the detection surface 11a at the position of the protruding member 20 corresponding to the own position mark P and is in a high protruding state, The process execution unit 57 forcibly matches the position with the parallel road U. Further, in the present embodiment, the guide route is reset so as to pass through the parallel road U, and the protruding state of the protruding member 20 is updated accordingly.

  In addition, the process execution unit 57 assigns the destination route information display process to the protruding member 20 corresponding to the position on the guide route from the own position to the destination, and corresponds to the position on the guide route from the departure place to the own position. A passage route information display process is assigned to the protruding member 20. The destination route information display process is a process for displaying future information (destination route information) related to the guide route from its own position to the destination. The destination route information includes, for example, the distance from the own position to the destination, the expected arrival time, the weather of the place passing from the own position to the destination, and the like. The passing route information display process is a process of displaying past information (passing route information) regarding the guide route from the departure place to the own position. The passing route information includes, for example, the distance from the departure place to the own position, the traveling time, and the like.

  FIG. 9 shows an example of the destination route information display process. When it is detected that the projecting member 20 corresponding to the road S constituting the guide route from its own position to the destination is operated to be separated, the process execution unit 57 is assigned to the separated projecting member 20. The destination route information display process is executed. After the detected object D moves along the detection surface 11a, the protruding member 20 which is in a high protruding state corresponding to the road S constituting the guide route at a position ahead of the own position in the traveling direction. When it is detected that the position is away from the detection surface 11a, the process execution unit 57 displays the destination route information on the display screen 41. FIG. 10 shows an example of the passage route information display process. When it is detected that the protruding member 20 corresponding to the road S constituting the guide route from the departure place to the own position is operated to be separated, the process execution unit 57 is assigned to the separated projecting member 20. The passing route information display process is executed. After the detected object D moves along the detection surface 11a, the protruding member 20 that is in a high protruding state corresponding to the road S that constitutes the guide route at a position on the rear side in the traveling direction from the own position. When it is detected that the position is away from the detection surface 11a, the process execution unit 57 displays the passage route information on the display screen 41. In addition, you may comprise so that these destination route information and passage route information may be output from the audio | voice output apparatus 88 as an audio | voice.

  Further, the process execution unit 57 assigns the specific facility information display process to the protruding member 20 corresponding to the specific facility Q. The specific facility information display process is a process of displaying information (specific facility information) regarding the specific facility Q having a characteristic to be a landmark. The specific facility information includes various types of information related to the specific facility Q such as name, type, attribute, and telephone number. As the specific facility Q to which such specific facility information display processing is assigned, a facility having a larger area than the surrounding facilities, a tall facility or the like compared to the surrounding facilities, and the like are suitable.

  FIG. 11 shows an example of the specific facility information display process. When it is detected that the protruding member 20 corresponding to the specific facility Q has been separated, the process executing unit 57 executes a specific facility information display process assigned to the separated protruding member 20. When it is detected that the detection object D moves along the detection surface 11a and then moves away from the detection surface 11a at the position of the protruding member 20 corresponding to the specific facility Q, the protrusion member 20 is in a high protruding state. The execution unit 57 displays the specific facility information on the display screen 41. In addition, you may comprise so that this specific facility information may be output as an audio | voice from the audio | voice output apparatus 88. FIG.

  Further, the process execution unit 57 assigns an operation mark selection process to the protruding member 20 corresponding to the operation mark 44. The operation mark selection process is a process for selecting and executing a process associated with a specific operation mark 44. When it is detected that the projecting member 20 corresponding to the operation mark 44 has been separated, the process execution unit 57 performs an operation mark selection process assigned to the projecting member 20 that has been separated. When it is detected that the detection object D moves along the detection surface 11a and then moves away from the detection surface 11a at the position of the protruding member 20 which is in a low protruding state corresponding to the operation mark 44, The process execution unit 57 causes the process associated with the operation mark 44 to be executed.

  As described above, the process execution unit 57 assigns a process to each projecting member 20 in the projecting state, and detects that the projecting member 20 is separated by the detected object D. Route reset processing, matching processing, destination route information display processing, passage route information display processing, specific facility information display processing, or operation mark selection processing can be executed alternatively.

  In addition, when the process execution unit 57 detects that the detection object D has moved away from the detection surface 11a at the position of the protruding member 20 that has not been protruded after moving along the detection surface 11a, The process according to the input pattern by the to-be-detected object D detected by the detection surface 11a is performed. In the present embodiment, the process execution unit 57 is a projecting member that is brought into a non-projecting state in correspondence with areas other than the road R, the specific facility Q, the own position mark P, and the operation mark 44 displayed on the display screen 41. When the separation operation associated with the single touch operation is detected in the region of the detection surface 11a where 20 is located, the process execution unit 57 executes the scrolling process of the map image according to the slide operation on the detection surface 11a. . The scroll process is a process for redisplaying the map image so as to be centered on a designated point (here, a point corresponding to the position where the separation operation is detected).

  Further, when it is detected that a pinch-out operation has been performed on the detection surface 11a, the processing execution unit 57 uses an input pattern (that is, an input pattern in which the intervals between a plurality of detection positions are widened) by the pinch-out operation. The enlarged display process is executed accordingly. The enlarged display process is a process for enlarging and displaying the image displayed on the display screen 41. FIG. 12 shows an example of this enlarged display process. In this example, the process execution unit 57 executes an enlarged display process according to the operation amount, with the center point of the image displayed on the display screen 41 at that time as the center. At this time, the image displayed on the display screen 41 is enlarged so that the enlargement ratio increases as the operation amount increases (as the interval between the plurality of detection positions is further increased).

  In addition, when it is detected that a pinch-in operation has been performed on the detection surface 11a, the processing execution unit 57 responds to an input pattern by the pinch-in operation (that is, an input pattern in which the intervals between a plurality of detection positions are narrowed). Perform reduced display processing. The reduced display process is a process for reducing and displaying the image displayed on the display screen 41. FIG. 13 shows an example of the reduced display processing. In this example, the process execution unit 57 executes a reduced display process according to the operation amount, with the center point of the image displayed on the display screen 41 at that time as the center. At this time, the image displayed on the display screen 41 is reduced so that the enlargement ratio decreases as the operation amount increases (as the interval between the plurality of detection positions becomes narrower).

  As described above, the process execution unit 57 performs the enlarged display process or the reduced display as the pattern input process when the input pattern by the plurality of detection objects D detected by the detection surface 11a matches the reference pattern defined in advance. Processing can be performed alternatively.

  By the way, in this embodiment, since the process execution part 57 is comprised so that a protrusion allocation process can be performed and a pattern input process is also executable, two processes may compete in some cases. For example, when the pinch-out operation is finished after the one fingertip or the like has touched the protruding member 20 due to the pinch-out operation, the enlarged display process and the last touched protrusion The protrusion assignment process assigned to the member 20 competes. In such a case, in the present embodiment, the process execution unit 57 is a case where it is detected that the protruding member 20 has been separated when the input pattern by the plurality of detection objects D matches the reference pattern. However, the pattern input process is executed without executing the protrusion assignment process. That is, the process execution unit 57 preferentially executes the pattern input process with respect to the protrusion assignment process.

  When the relative positional relationship is kept substantially constant in the multi-touch operation, the user is operating the detection surface 11a while another fingertip or the like is in contact with the detection surface 11a. It is estimated that there is a possibility that the detection surface 11a is operated. On the other hand, when the relative positional relationship is changed in the multi-touch operation, it is estimated that the user is likely to operate the detection surface 11a with a plurality of fingertips or the like with some intention. For this reason, only the input pattern that is estimated to reflect the user's intention by setting the pattern in which the relative positional relationship of the detection positions on the detection surface 11a of the plurality of detection objects D changes as a “reference pattern”. Can be selected and a pattern input process corresponding to it can be executed.

  The process execution unit 57 does not execute the pattern input process when the input pattern by the multi-touch operation does not match the reference pattern. At this time, when at least one fingertip or the like that has performed the multi-touch operation also simultaneously performs the separation operation on the protruding member 20 that is in the protruding state, the process execution unit 57 causes the protruding member 20 to Execute the assigned protrusion assignment process. FIG. 14 shows an example of the route resetting process executed in such a situation. This is because, when the relative positional relationship is kept substantially constant in the multi-touch operation, the user intends the single touch operation but unintentionally touches the detection surface 11a with another fingertip or the like. This is because it is assumed that there is a possibility. Therefore, in such a case, the projecting assignment process assigned to the projecting member 20 that is finally separated is executed so as to reflect the original intention of the user as much as possible.

  Furthermore, in this embodiment, the process execution unit 57 uses the detection surface 11a when the input pattern by the multi-touch operation does not match the reference pattern and the separation operation on the protruding member 20 in the protruding state is not detected. Processing according to the input pattern by the detected object D to be detected is executed. In this example, a map image scroll process is executed in response to a slide operation (tracing operation) on the detection surface 11a.

4). Processing of Input System Processing performed by the input system 3 according to the present embodiment will be described with reference to FIGS. The processing described below is executed by hardware or software (program) or both constituting each functional unit of the operation input calculation unit 50. When each of the above functional units is configured by a program, the arithmetic processing device included in the control arithmetic unit 6 including the operation input arithmetic unit 50 operates as a computer that executes the program configuring each functional unit.

  As shown in FIG. 15, a display image is first created (step # 01). In this example, a map image image mainly including the road R, the specific facility Q, the own position mark P, the operation mark 44, and the like is created. Then, the protruding state setting process is executed (# 02).

  As shown in FIG. 16, in the protruding state setting process, the own position is determined by the own position determining unit 71 (step # 21). Based on the determined own position, the map image around the current position and information related to the map contents are acquired from the map database 85 (# 22, # 23). Based on the acquired map image and information related to the map contents, a turn list centered on the own position is created (# 24). Based on the map image, a branch route list including a branch point and a branch route connected to the turn list is created (# 25). Based on the information relating to the map contents, the specific facility Q to be put on the turn list is extracted, and the facility list is created (# 26).

  Based on the turn list set in step # 24, the protruding state of the protruding member 20 corresponding to the guide route is set (# 27). Further, based on the branch path list set in step # 25, the protruding state of the protruding member 20 corresponding to the branch path is set (# 28). Further, based on the facility list set in step # 26, the protruding state of the protruding member 20 corresponding to the specific facility Q is set (# 29). Further, the protruding state of the protruding member 20 representing the own position mark P that displays the own position determined in step # 21 is set (# 30). The protruding state of each protruding member 20 set in steps # 27 to # 30 is synthesized, and the protruding state of the entire protruding member 20 is set (# 31). At this time, when the operation mark 44 is displayed on the display screen 41, the protruding state of the protruding member 20 corresponding to the operation mark 44 is also set. Thus, the protruding state setting process is completed.

  When the projecting state setting process is completed, the process returns to FIG. 15, and an image is displayed on the display screen 41 based on the display image image created in step # 01, and the projecting state is projected based on the projecting state synthesized in step # 31. The member 20 is driven back and forth (# 03). As a result, the projecting member 20 corresponding to the road R, the specific facility Q, the own position mark P, and the operation mark 44 displayed on the display screen 41 is set to a high projecting state or a low projecting state. In this state, the input determination process is executed (# 04).

  As shown in FIG. 17, in the input determination process, when any operation on the detection surface 11a is detected (step # 41: Yes), it is determined whether or not it is a single touch operation (# 42). In the case of a multi-touch operation (# 42: No), when the relative positional relationship of a plurality of detection positions changes (# 43: Yes), the change direction is further determined (# 44). If they have moved relative to each other (# 44: Yes), the process execution unit 57 instructs the navigation calculation unit 70 to execute the reduced display process (# 45). If they have moved relative to each other (# 44: No), the process execution unit 57 instructs the navigation calculation unit 70 to execute the enlarged display process (# 46).

  When the operation on the detection surface 11a is a single touch operation (# 42: Yes), or when the relative positional relationship between a plurality of detection positions by the multi-touch operation does not change (# 43: No), these operations are further performed. Is determined (# 47). If the operation end position is not the position of the protruding member 20 in the protruding state (# 47: No), the process execution unit 57 scrolls with respect to the navigation calculation unit 70 according to the tracing operation on the detection surface 11a. The process is instructed to be executed (# 48). On the other hand, if the operation end position is the position of the protruding member 20 in the protruding state (# 47: Yes), the protrusion allocation process is executed (# 49).

  As shown in FIGS. 18 and 19, in the projecting assignment process, if the projecting member 20 that is contacted last is on the turn list (step # 51: No), the details of the position are further determined. When the projecting member 20 corresponding to its own position touched last (# 52: Yes) and there is a parallel road within a predetermined distance from the guide route (# 53: Yes), the process execution unit 57 is used for navigation. The operation unit 70 is instructed to execute the forced matching process (# 54). If there is no parallel road within a predetermined distance from the guide route (# 53: No), the process execution unit 57 instructs the navigation calculation unit 70 to execute the rematching process (# 55).

  If the last contacted is the protruding member 20 corresponding to the guide route from the departure place to the own position (# 56: Yes), the process execution unit 57 sends the passage route information to the navigation calculation unit 70. An instruction is given to execute the display process (# 57). If the last contact is the protruding member 20 corresponding to the guide route from its own position to the destination (# 56: No), the process execution unit 57 sends the destination route information to the navigation calculation unit 70. An instruction is given to execute the display process (# 58).

  When it is not the projecting member 20 on the turn list that is finally contacted (# 51: Yes), and when the projecting member 20 is on the branch path (# 59: No), the process execution unit 57 performs navigation. The operation unit 70 is instructed to execute the route re-search process (# 60). Here, it is instructed to execute the route re-search process so that the guide route passes through the point corresponding to the projecting member 20 that has been contacted last. Further, when the last contact is not the protruding member 20 on the turn list, nor the branching path (# 52: Yes, # 59: Yes), it is the protruding member 20 on the specific facility Q. In this case (# 61: Yes), the process execution unit 57 instructs the navigation calculation unit 70 to execute the specific facility information display process (# 62).

  If each process instructed to be executed by the process execution unit 57 is a process that can be executed by the navigation device 1 (# 63: Yes), the navigation calculation unit 70 executes the process (# 64), and the projecting allocation is performed. The process ends. On the other hand, if the process is not executable by the navigation device 1 (# 63: No), the navigation calculation unit 70 ends the protrusion assignment process without executing the process. In addition, when the projecting member 20 that is finally contacted by the separation operation is not on the turn list, the branch path, or the specific facility Q (# 51: Yes, # 59: Yes, # 61: No) In this example, an operation mark selection process for executing the process associated with the operation mark 44 is executed (# 66). Thereafter, the protrusion assignment process is terminated. Then, returning to FIG. 17, the input determination process is terminated.

  When the input determination process ends, the process returns to FIG. 15 to determine whether or not the display image on the display screen 41 has been changed (# 05). If there is no screen transition (# 05: No), the input determination process is executed again. On the other hand, when there is a screen transition, for example, when the guidance route is changed as a result of the input determination process, when the own position is forcibly corrected, or when the map image is updated due to movement of the own position, etc. (# 05: Yes), the process is terminated. Note that the processing from step # 01 is executed again on the display image after the change. The above processing is repeatedly executed repeatedly.

  In the present embodiment, the coordinates of the display screen 41 and the coordinates of the detection surface 11a are associated with each other and correspond to the road R, the specific facility Q, the own position mark P, and the operation mark 44 displayed on the display screen 41. The protruding member 20 is in a protruding state. In particular, in the present embodiment, when the road R and the own position mark P are displayed on the display screen 41, the protruding member 20 corresponding to the road R and the own position mark P is set in the protruding state. Thus, the user can recognize the shape of the road R and the like displayed on the display screen 41 and the aggregate shape formed by the aggregate of the tip portions of the plurality of projecting members 20 in the projecting state recognized by tactile sense. It can be easily correlated in contrast. At this time, the association can be easily performed by considering the relationship with the own position. As a result, the user can easily perform a predetermined operation on the detection surface 11a at a specific position without gazing at the display screen 41.

  Then, after the user moves the fingertip or the like along the detection surface 11a and tactilely recognizes the protruding projecting member 20, the user only performs a separation operation to separate the fingertip or the like from the detection surface 11a. The process assigned to the member 20 can be executed. That is, after recognizing that the target position on the detection surface 11a has been reached by relying on the tactile sensation, the target process can be executed without requiring any special operation other than separating the fingertip or the like from the detection surface 11a. it can. Even if the initial contact position on the detection surface 11a differs from the target position due to vibration or the like, by moving the fingertip or the like to the target position and then moving it away from the detection surface 11a, Can be executed. Therefore, the input system 3 excellent in convenience can be realized.

  Further, in the present embodiment, the user further indicates that the route attribute indicates a road constituting the guide route according to the route attribute of the road corresponding to the projecting member 20 that is last touched. Depending on the position attribute, different protrusion assignment processes can be executed. Specifically, the route is selected from route re-search processing, forced matching processing, re-matching processing, passing route information display processing, and destination route information display processing according to information of at least one of the route attribute and the position attribute. The protrusion assignment process can be executed. Therefore, it is possible to appropriately execute necessary processing in accordance with road attributes that are important information in navigation without paying attention to the display screen 41.

  Further, in the present embodiment, the process execution unit 57 protrudes even when it is detected that the protruding member 20 is operated when the input pattern by the plurality of detection objects D matches the reference pattern. The pattern input process is executed without executing the allocation process. Therefore, when the protrusion assignment process and the pattern input process compete, the overall process can be smoothly executed by adopting a configuration in which the pattern input process is executed with priority.
