Description

  The present invention relates to an input device.

  An input device for operating the operation of the electronic device using a pointing device such as a mouse or a trackball connected to the electronic device or moving a pointer or the like on the screen of the display device in accordance with the operation direction There is. These input devices are operated by a user to output coordinates corresponding to the operation direction to an electronic device.

  When such an input device is connected to an electronic device and used as an input device for an electronic device, the direction imaged by the user does not match the direction set for the electronic device, and the pointer points to the direction that the user thinks. Or the like cannot be moved or the electronic device cannot be operated.

For example, Patent Document 1 discloses a driving device including an operation lever operated by a driver. According to this, by operating the operation lever back and forth, right and left, the vehicle can be steered, operated by the accelerator, and operated by the brake. Further, the vehicle is operated according to the operation of the operation lever supported by the vehicle body so as to be tiltable. The type of control target value can be switched.
JP 2002-337715 A

  However, the relationship between the operation method of the operation lever (operation in a predetermined direction) and the target value is set in advance, and the “predetermined direction” has already been determined in the assembled state on the vehicle body. , It is possible to assign different functions (eg rudder angle, steering speed) to “left and right operation”, but there is a discrepancy between the left and right operation set in advance and the left and right operation imagined by the user. Can happen. In this case, the user is forced to perform predetermined left and right operations, and there are cases where the user has to operate in an unnatural posture depending on the mounting state of the operation lever on the vehicle body, the user's body shape, and the like. .

  In recent years, various in-vehicle devices are mounted on vehicles, and an input device for operating these in-vehicle devices may be provided on an instrument panel or the like of the vehicle. When operating an electronic device such as an in-vehicle device using the input device as described above, the user is seated at a predetermined position such as a driver's seat, and the input device is incorporated at a predetermined position. The positional relationship between the user and the input device is not necessarily set optimally, and it is likely that the input that the user has assumed cannot be performed especially due to the input by the unnatural posture of the user.

  An object of the present invention is to allow a user to make a desired input without matching the direction imaged by the user and the direction set on the electronic device side in an input device used for operation input of an in-vehicle electronic device. It is to solve the problem that cannot be done.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned problem, it relates to an input device used for operation input of an in-vehicle electronic device.
A pointing device including an operation unit for performing position designation and position selection on a screen of a display device provided in the vehicle, and an operation input displacement detection unit for detecting an operation input displacement by the operation unit;

Coordinate conversion rules for converting the indicated position in the reference coordinate system by the reference coordinate system indicated position recognition means to the indicated position in the virtual coordinate system that the operator senses, the master locus in the reference coordinate system and the test operation locus Coordinate transformation rule determining means for determining based on the correspondence relationship with
Instructed position coordinate conversion means for converting the indicated position coordinates in the reference coordinate system that the operator inputs using the pointing device after inputting the test operation locus into the designated position coordinates in the virtual coordinate system in accordance with the determined coordinate conversion rule. When,
Screen instruction position setting means for setting the indicated position coordinates after conversion as a current instruction position on the screen of the display device;
It is characterized by having.

  According to the above configuration, when the user operates the pointing device, the reference position in the reference coordinate system is recognized by the reference coordinate system specified position recognition unit. Then, the input information of the test operation locus drawn by the user assuming the master locus is obtained as actual operation locus information by the actual operation pattern operation locus information obtaining means, and the master locus and the test operation locus are obtained by the coordinate conversion rule determining means. The coordinate conversion rule can be determined from the correspondence relationship between

  In other words, when the user operates the pointing device, the direction that the user thinks may deviate from the direction in the reference coordinate system due to the user's operation habits, etc. And test operation trajectory information can be compared, and a coordinate conversion rule can be created in a direction to correct the deviation.

  Then, the designated position coordinate conversion means converts the designated position coordinates input by the user using the pointing device to the designated position coordinates in the virtual coordinate system recognized by the user after inputting the test operation locus, and sets the screen designated position. By means, it can be set as the current designated position on the display screen. In other words, according to the coordinate conversion rules, by converting the indicated position coordinates input by the user, the deviation caused by the user's operation stick etc. is corrected, and the position indication and position selection on the screen is performed as the position assumed by the user. Can do.

  The input device of the present invention may be configured to include a test operation input instruction output means for outputting an instruction for prompting the operator to input a test operation locus along the master locus. Specifically, the test operation input instruction output means can be configured to display and output an image of the master trajectory in the reference coordinate system on the screen of the display device. The user inputs a test operation locus according to the display output on the screen. Or you may comprise so that it may output by an audio | voice. With this configuration, the user can easily input a test operation trajectory and what test operation trajectory should be input.

  The coordinate conversion rule determining means may be configured to determine the coordinate conversion rule based on the actual operation trajectory information repeatedly acquired by the actual operation pattern operation trajectory information acquisition means as the test operation trajectory is repeatedly input. it can. That is, since the coordinate conversion rule is determined based on the actual operation trajectory information from the repeated test operation trajectory, the deviation of the user input can be corrected more accurately.

  More specifically, the coordinate conversion rule determining unit determines the representative operation track based on the actual operation track information repeatedly acquired by the actual operation pattern operation track information acquiring unit, and determines the master track and the representative operation track. It can be set as the structure which determines a coordinate transformation rule based on a correspondence. For example, the representative operation locus can be determined by the least square method or the like for the test operation locus by the user. In accordance with the coordinate conversion rules created in this way, by converting the indicated position coordinates input by the user, the displacement caused by the user's operation stick etc. is corrected, and the position indication on the screen as the position assumed by the user and Position selection can be performed.

  The operation unit of the pointing device has a two-dimensional operation degree of freedom, and the operation input displacement detection unit can be configured to detect a two-dimensional operation input displacement by the operation unit. Thus, by setting it as the structure which has a two-dimensional operation freedom, it can utilize as an input device of various vehicle-mounted electronic devices.

  Note that even if the operation unit of the pointing device is configured to have a one-dimensional operation freedom, a position instruction and position selection on the screen can be performed as a position assumed by the user by correcting a deviation caused by a user's operation rod or the like. Can be done.

The master trajectory is defined in a shape that can uniquely determine the first reference direction and the second reference direction that intersect each other on the reference coordinates,
The coordinate conversion rule determining means determines a first reference direction corresponding to the first reference direction and a second reference direction corresponding to the second reference direction from the actual operation locus, and the first reference direction, the first reference direction, and the first reference direction A coordinate conversion rule can be determined based on each correspondence between the two reference directions and the second reference direction.

  Since the first reference direction and the second reference direction corresponding to each of the two directions of the first reference direction and the second reference direction are determined, and the coordinate conversion rule is determined from the correspondence relationship with each direction, it is more appropriate. In addition, position designation and position selection on the screen can be performed as positions assumed by the user.

Furthermore, the master trajectory is defined in a shape that can uniquely determine the first reference line segment and the second reference line segment that intersect each other on the reference coordinates,
The coordinate conversion rule determining means is a line segment acquisition means for acquiring a first reference line segment corresponding to the first reference line segment and a second reference line segment corresponding to the second line segment from the actual operation locus corresponding thereto. And a primary conversion rule for superimposing the first reference line segment, the first reference line segment, the second reference line segment, and the second reference line segment on the reference plane by rotation, translation, and enlargement / reduction, respectively. Primary conversion rule determining means for determining as a coordinate conversion rule can be provided.

  The first reference line segment and the second reference line segment corresponding to each of the first reference line segment and the second reference line segment are acquired by the line segment acquisition unit, and the corresponding to each line segment is acquired by the primary conversion rule determination unit The coordinate conversion rule can be determined by finding the primary conversion rule from the relationship. For this reason, it is possible to perform position designation and position selection on the screen more accurately as the position assumed by the user by converting the designated position coordinates input by the user according to this coordinate conversion rule.

  Furthermore, the first reference line segment and the second reference line segment are each divided into a first segment and a second segment at the intersection point, and the first reference line segment and the second reference line segment are also divided into the first segment and the second segment at the intersection point, respectively. In addition to being divided into two segments, the primary conversion rule determining means determines the enlargement / reduction rules for the first reference line segment, the first reference line segment, the second reference line segment, and the second reference line segment, respectively. In each corresponding segment, it can be determined independently.

  Since the first reference line segment and the second reference line segment are each divided into the first segment and the second segment at the intersections, the two-dimensional coordinate system is divided into four areas, and each area is different. Coordinate transformation can be performed. By doing so, it is possible to perform position designation and position selection on the screen as the position assumed by the user more accurately.

More specifically, the first reference line segment and the second reference line segment are defined as a reference cross figure orthogonal to each other,
The line segment acquisition means acquires the first reference line segment and the second reference line segment as a reference cross figure orthogonal to each other,
The primary conversion rule determining means determines a translation rule for superimposing the intersection of the reference cross figure on the intersection of the standard cross figure, and then superimposes corresponding line segments of the reference cross figure and the standard cross figure by rotational movement. A rotational movement rule to be matched can be determined, and thereafter, the corresponding segment can be configured to determine the enlargement / reduction rule in such a manner that the end points of the segments opposite to the intersection point do not move without moving the intersection point. . The first reference line segment and the second reference line segment are determined so as to coincide with the vertical reference line defined at the horizontal center on the display device screen and the horizontal reference line defined at the vertical center. It has been.

  By configuring in this way, it is possible to perform position designation and position selection on the screen as the position assumed by the user more accurately.

  A reference cross figure can be defined as a master locus. In the cross graphic, the first reference line segment and the second reference line segment are formed orthogonally as described above, and by using such a graphic as a reference, coordinates in two dimensions are uniquely defined. be able to.

  Alternatively, the master trajectory can be defined as a circle or ellipse circumscribing the reference cross shape. When a user inputs a test operation trajectory using a circle or an ellipse as a master trajectory, the user draws an ellipse without drawing a perfect circle. For this reason, the test operation trajectory drawn by the user is approximated as an ellipse, and the major and minor axes of the ellipse are set as the first reference line segment and the second reference line segment, so that the coordinates from the reference cross shape are the same as above. Conversion rules can be determined.

Furthermore, the input device of the present invention includes a coordinate conversion rule storage unit that stores a plurality of coordinate conversion rules determined by the coordinate conversion rule determination unit;
Coordinate conversion rule selection means for selecting any one of a plurality of stored coordinate conversion rules,
The designated position coordinate conversion means can be configured to convert the designated position coordinate in the reference coordinate system into the designated position coordinate in the virtual coordinate system according to the selected coordinate conversion rule.

  According to the above configuration, since a plurality of coordinate conversion rules can be stored, it is possible to select a coordinate conversion rule according to the situation, and to convert the coordinate to the indicated position coordinate in the virtual coordinate system according to the selected coordinate conversion rule. it can.

The coordinate conversion rule storage means stores coordinate conversion rules respectively corresponding to a plurality of users.
The coordinate conversion rule selection means can be configured to have user specifying means for specifying the user of the input device and to select a coordinate conversion rule corresponding to the specified user.

  According to the above-described configuration, since the attitude or operating rod for operating the input device varies depending on the user, a coordinate conversion rule can be created and stored for each user, and the user uses his own coordinate conversion rule. be able to.

A pointing device is provided on the vehicle at a position where it can be operated from a plurality of seats.
The coordinate conversion rule storage means stores coordinate conversion rules respectively corresponding to a plurality of seats,
The coordinate conversion rule selection means can be configured to include a seat specification means for specifying coordinates at which the pointing device is operated, and to select a seat conversion rule corresponding to the specified seat.

  For example, when the input device is operated from the driver's seat and when operated from the passenger seat, the posture of the user is different. For this reason, since the coordinate conversion rule corresponding to the seat is stored, accurate coordinate conversion can be performed.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram schematically illustrating an electrical block diagram of an input device 1 according to an embodiment. The input device 1 includes a haptic device (haptic device) 2 attached to a vehicle instrument panel or the like, which is configured as a pointing device for designating a position corresponding to the screen of the display device 6 mounted on the vehicle, and And a controller 10 to be controlled. The haptic device 2 has a trackball unit (operation unit) 21 operated by a user, and the controller 10 applies a reaction force to the trackball unit 21 against an operating direction. , 32 are controlled. Hereinafter, each detail is demonstrated.

  First, the haptic device 2 will be described. The haptic device 2 holds the housing 28 in a state where the operation surface 21a of the trackball portion 21 is exposed. FIG. 2 is a diagram showing an outline of the appearance of the haptic device 2. In addition to the trackball unit 21 for indicating a position corresponding to the screen of the display device 6, the haptic device 2 returns to the original screen and a determination switch 201 for selecting an operation associated with the position. The return switch 202 is provided on the outer surface.

  The trackball portion 21 has a spherical operation surface 21 a, and a support post 24 extends from the back side thereof and is inserted into the storage portion 27. A spherical portion 22 is formed in the middle of the column 24, and is supported by a bearing 23 provided in the storage unit 27 so that the column 24 is swingably supported with respect to the storage unit 27.

  With this configuration, the trackball unit 21 is movable in a direction along the operation surface 21a that is a contact surface with which the user contacts, and the user can move his / her hand (fingertip) and the trackball unit 21. It is a touch operation type that operates using the frictional force.

  The trackball portion 21 is a hemispherical movable area along the operation surface 21a, and can be freely moved within the range. That is, the user can move in any direction (360 degrees) in the in-plane direction of the contact surface from the position where his / her hand (fingertip) contacts the operation surface 21a (excluding the end of the movable range). ).

  The operation surface 21 a of the trackball portion 21 is a spherical surface centered on the spherical portion 22 indicated by the bearing 23. A projection 29 is provided at the center of the operation surface 21a to inform the user of the center position.

  The storage unit 27 is provided with an optical image sensor (operation input displacement detection unit) 41 that detects a direction (operation direction) in which the trackball unit 21 is operated. The optical image sensor 41 is mounted on the bottom surface in the storage unit 27 together with a light source (not shown). On the other hand, a lower end 25 having a spherical end surface 25a centering on the spherical portion 22 supported by the bearing 23 is provided at the lower end of the column 24 extending from the trackball portion 21, and this end surface 25a is provided. Has a predetermined detection pattern.

  For detection of the operation direction, light is emitted from a light source, and an image of a detection pattern formed on the end surface 25a of the lower end 25 is guided to the optical image sensor 41 through the light guide tube 26, thereby swinging the column 24. The direction and the swing amount (swing angle), that is, the operation amount of the trackball portion 21 in the XY orthogonal coordinates can be detected. The position detection signal detected by the optical image sensor 41 is fed back to the controller 10. Note that, as the operation direction detection means, a photo encoder or the like provided on each of the orthogonal X axis and Y axis can also be applied.

  The trackball unit 21 that is an operation unit of the haptic device 2 that is a pointing device has a two-dimensional operation freedom, and the optical image sensor 41 that is an operation input displacement detection unit is a two-dimensional operation input by the operation unit. The displacement is detected.

  The storage unit 27 is also provided with motors 31 and 32 as actuators that can apply force to the trackball unit 21 in a direction in which operation is allowed. The motors 31 and 32 are respectively provided with respect to the X axis and the Y axis which are orthogonal to each other, and are connected to the support column 24 via a shaft (not shown) to convert the rotational motion into a linear motion along the axial direction. By transmitting to 24, a force is applied to the trackball portion 21. The motors 31 and 32 operate so as to apply an operation reaction force against the operation direction to the trackball portion 21 based on a drive signal from the controller 10.

  Next, the controller 10 will be described. The controller 10 includes a controller ECU (Electronic Control Unit) 100 that controls the haptic device 2. The controller ECU 100 includes a microprocessor in which a CPU 101, a ROM 102, a RAM 103, an input port 109, and an output port 108 are connected via a bus 105. The serial communication bus 9 that constructs the in-vehicle network and the bus 105 inside the controller ECU 100 are connected via a serial communication interface (I / F) 106. The ROM 102 stores a program executed by the CPU 101 and data necessary for the program. Specifically, a coordinate transformation rule creation program 102a for creating a coordinate transformation rule and a coordinate transformation program 102b for transforming coordinates based on the coordinate transformation rule are stored. The RAM 103 is used as a work area when the CPU 101 executes a program. Furthermore, a storage unit 104 that stores the coordinate conversion rules created by the coordinate conversion rule creation program 102a is provided.

  The controller 10 also includes an A / D conversion circuit 45 that digitally converts the position detection signal fed back from the optical image sensor 41 and inputs the digital signal to the input port 109. In addition, the controller 10 calculates the motors 31 and 32 built in the haptic device 2 based on the control signal calculated by the controller ECU 100 based on the position detection signal fed back from the optical image sensor 41 and output from the output port 108. A driver circuit 35 for driving is also provided.

  When the controller 10 detects the direction in which the trackball unit 21 is operated based on the position detection signal fed back from the optical image sensor 41, the controller 10 drives the motors 31 and 32 so as to apply an operation reaction force against the operation direction. To do.

  The serial communication bus 9 is connected to the display device 6 disposed on the instrument panel 61 of the vehicle. The controller 10 receives a position detection signal fed back from the optical image sensor 41 and a detection signal for pressing the decision switch 201. It transmits to the display device 6. When receiving the position detection signal or the press detection signal, the display device 6 performs processing for executing various operations displayed on the screen in association with the operation direction of the trackball unit 21. Thus, the input device 1 functions as a pointing device that designates a position corresponding to the screen of the display device 6.

  As described above, the position instruction by the user operating the haptic device 2 is processed by the controller ECU 100, and the indicated position is displayed on the screen of the display device 6. When the user operates the haptic device 2, a direction that the user thinks may be different from a direction in the reference coordinate system of the display device 6 due to a user's operation habit or the like. As described above, the master trajectory and the test operation trajectory information are compared, and a coordinate conversion rule is created in a direction in which the deviation is corrected. Then, the designated position coordinates input by the user using the haptic device 2 are converted into designated position coordinates in a virtual coordinate system that the user senses and the display position is output to the display device 6. Therefore, the controller ECU 100 (hereinafter also referred to as a control unit) constitutes a reference coordinate system indicated position recognition means, an actual operation pattern operation locus information acquisition means, a coordinate conversion rule determination means, an indicated position coordinate conversion means, and a screen indication position setting means. To do.

  FIG. 2 shows how the user operates the haptic device 2. The user can operate the trackball unit 21 forward and backward, left and right, etc. by placing a hand on the operation surface 21 a of the haptic device 2. The trackball unit 21 has a two-dimensional freedom of operation. Thereby, position indication and position selection on the screen of the display device 6 can be performed.

  FIG. 3 shows an installation example of the input device 1 of the present invention. The input device 1 is provided in the vicinity of the navigation device 62 as an input device of the navigation device 62 provided in front of the instrument panel 61 of the vehicle. The haptic device 2 of the input device 1 includes a driver seat and a passenger seat. It is possible to operate from. However, it is provided on the left hand side from the driver's seat side and on the right hand side from the passenger seat, and the user's operation posture is symmetrical, so the coordinates are converted for each seat (or for each user). A coordinate conversion rule is generated and stored in the storage unit 104, and the input is converted and displayed based on the coordinate conversion rule.

  By operating the haptic device 2 of the input device 1 as described above, a position instruction can be given on the screen of the display device 6 of the navigation device 62 as shown in FIG. That is, the selection unit 63 displayed on the screen as shown in FIG. 5 can be selected to perform a desired operation. At this time, the position instruction by the user's operation of the haptic device 2 is displayed on the screen as a position converted according to the coordinate conversion rule. Therefore, even if the position instruction input by the user is deviated from the position on the display device 6, the position instruction is displayed as a position according to the coordinate conversion rule, and thus is displayed as a position assumed by the user.

  FIG. 5 shows a functional block diagram of the input device 1. The input device 1 is divided into a test operation mode for creating a coordinate conversion rule (coordinate conversion rule) and a normal operation mode for converting and displaying designated position coordinates input by the user in accordance with the coordinate conversion rule.

  In the test operation mode, the master locus information stored in the master locus information storage unit 56 (corresponding to the storage unit 104) is output to the output unit 57 (corresponding to the display device 6 or the audio output unit 7) to the user. Prompt input of test operation trajectory. Then, the actual operation trajectory information and the master trajectory information obtained by the user operating the haptic device 2 are input to the coordinate transformation rule creation unit 55 (corresponding to the control unit, that is, the controller ECU 100), and the coordinate transformation rule is created. . The created coordinate conversion rule is stored in the coordinate conversion rule storage unit 53 (corresponding to the storage unit 104).

  In the normal operation mode, the coordinate data of the reference coordinate system when the user operates the haptic device 2 is input to the coordinate conversion unit 52. The coordinate conversion unit 52 is a coordinate conversion rule that is a coordinate conversion rule stored in the coordinate conversion rule storage unit 53 (a plurality of coordinate conversion rules are stored, and a coordinate conversion rule corresponding to an operating user is used). Thus, the coordinate data of the reference coordinate system is converted into virtual coordinate data and transmitted to the display processing unit 54. The display processing unit 54 is configured in the display device 6, and corrects a shift caused by a user's operation rod or the like by converting an instruction position coordinate input by the user, and the position assumed by the user is displayed on the screen. Position indication and position selection can be performed.

  The operation processing of the in-vehicle device (navigation device 62) by the haptic device 2 will be described with reference to FIG. First, when the power of the in-vehicle device is turned on, the control unit (controller ECU) 100 determines whether it is necessary to create a coordinate conversion rule (S1). If a coordinate conversion rule has already been created and there is no need to create a new rule (S1: NO), the process proceeds to S3. If it is necessary to create a coordinate transformation rule (S1: YES), the control unit 100 notifies the user of the coordinate transformation rule creation and performs a coordinate transformation rule creation process (S2). Alternatively, as shown in FIG. 14A, a selection screen is displayed on the screen of the display device 6, and the user can operate the haptic device 2 to select a new coordinate conversion rule creation. You can also.

  The coordinate conversion rule creation process in S2 will be described with reference to FIG. The coordinate conversion rule creation unit 55 instructs the master trajectory information to the master trajectory information storage unit 56 (S11). The coordinate conversion rule creation unit 55 instructs the master track information storage unit 56 to provide the master track information, so that the master track information is output from the master track information storage unit 56 to the output unit 57 (S12). That is, an instruction output for prompting the user (operator) to input a test operation locus along the master locus is performed.

  As the master trajectory, it is possible to use a master trajectory that has a shape that can uniquely determine the first reference line segment and the second reference line segment that intersect each other on the reference coordinates. Specifically, as shown in FIG. 8, a reference cross figure in which the first reference line segment and the second reference line segment are orthogonal to each other can be used. The first reference line segment and the second reference line segment are each divided into a first segment and a second segment at intersections. It should be noted that both end points of the first reference line segment and both end points of the second reference line segment of the reference cross shape correspond to both end points in the front-rear and left-right directions of the trackball portion 21 of the haptic device 2.

  For example, the output of the master locus is output by the audio output unit 7 as “Please operate the knob several times up and down several times left and right each time”. Alternatively, a master locus as shown in FIG. 8 may be displayed on the screen of the display device 6. That is, an image of the master locus in the reference coordinate system may be displayed and output on the screen of the display device 6. However, in order to create a coordinate conversion rule from the user's operation stick, when the master locus is displayed, the display is erased before the user operates to prevent the user from tracing the display.

  The input from the haptic device 2 by the user is input to the coordinate conversion rule creation unit 55, and is recorded as actual operation trajectory information of the test operation trajectory drawn while assuming the master trajectory (S13). If the input operation of the test operation locus is completed (S14: YES), the coordinate conversion rule creation unit 55 stops the recording of the test operation locus from the haptic device 2 by the user (S15).

  The coordinate conversion rule creation unit 55 performs a coordinate conversion rule calculation process (S16). The coordinate conversion rule calculation process will be described with reference to FIG. The coordinate conversion rule creation unit 55 calculates the X ′ axis and the Y ′ axis from the locus by the user's operation (S21). Specifically, the coordinate conversion rule creation unit 55 extracts a predetermined number of points as sampling points from the trajectory in the X ′ direction by the user's operation as shown in FIG. Then, as shown in FIG. 10B, the X ′ axis is calculated from the sampling point by the least square method. That is, the representative operation locus is determined based on the actual operation locus information repeatedly input. Similarly, the Y ′ axis is calculated from the locus in the Y ′ direction. Next, the coordinate conversion rule creation unit 55 calculates the intersection of the X ′ axis and the Y ′ axis as the origin O ′ (S22). Thereby, a reference cross figure is determined.

  The coordinate conversion rule creation unit 55 translates the reference cross shape so that the origin O 'overlaps the origin O, and stores the translation amount T (S23). Next, as shown in FIG. 10C, the coordinate conversion rule creation unit 55 coordinates the coordinate so that the X ′ axis and the Y ′ axis of the reference cross shape coincide with the X axis and the Y axis of the reference cross shape. The system is rotated and the rotation amount R is stored (S24).

  Subsequently, the coordinate conversion rule creation unit 55 obtains an X-direction positive region expansion constant Mx1 that increases the distance from the origin so that the maximum point x1 ′ on the X ′ axis coincides with the maximum point x1 on the X axis. Mx1 is obtained by x1 / x1 '. Similarly, the coordinate conversion rule creation unit obtains an X-direction negative region expansion constant Mx2 that increases the distance from the origin so that the minimum point x2 ′ on the X ′ axis coincides with the minimum point x2 on the X axis. Mx2 is determined by x2 / x2 '.

  The coordinate conversion rule creation unit 55 obtains the Y-direction positive area expansion constant My1 and the Y-direction negative area expansion constant My2 in the same manner as the X-direction positive area expansion constant Mx1 and the X-direction negative area expansion constant Mx2 (S25). The coordinate conversion rule creation unit 55 stores the expansion constants Mx1, Mx2, My1, My2 in the coordinate conversion rule storage unit 53.

  That is, the coordinate conversion rule creation unit 55 determines a translation rule for superimposing the intersection of the reference cross figure on the intersection of the standard cross figure, and then rotates the corresponding line segments of the reference cross figure and the standard cross figure. The rotational movement rule to be overlapped by the movement is determined, and then the enlargement / reduction rule is determined in such a manner that the corresponding segment end points coincide with each other without moving the intersection of the corresponding segments.

  In other words, the coordinate conversion rule creation unit 55 includes the first reference line segment (X axis), the first reference line segment (X ′ axis), the second reference line segment (Y axis), and the second reference line segment (Y ′). The primary conversion rule for superimposing the axis) by rotation, parallel movement, and enlargement / reduction on the reference plane is calculated. This is determined to coincide with the vertical reference line defined at the center in the horizontal direction on the screen of the display device 6 and the horizontal reference line defined at the center in the vertical direction. In addition, the first reference line segment (X axis) and the second reference line segment (Y axis) are each divided into a first segment (positive area) and a second segment (negative area) at the intersections, and the first reference line segment (X′-axis) and second reference line segment (Y′-axis) are also divided into two segments, the first segment (positive area) and the second segment (negative area) at the intersections, respectively, Each of the one reference line segment, the first reference line segment, the second reference line segment, and the second reference line segment is determined independently in each corresponding segment. The coordinate conversion rule creation unit 55 constitutes a line segment acquisition unit and a primary conversion rule determination unit.

  Next, coordinate conversion in the normal operation mode will be described.

When the user operates the haptic device 2 in the normal operation mode to move the position indicating unit on the display screen of the in-vehicle device, the coordinate converting unit 52 acquires the specified position (S4). Each coordinate point that draws a trajectory by the operation of the haptic device 2 is converted by the coordinate conversion unit 52 so as to be the designated position in the virtual coordinate system for recognizing the user's sensation from the coordinates in the reference coordinate system (S5).

  Specifically, the coordinate conversion unit 52 calls a coordinate conversion rule from the coordinate conversion rule storage unit 53, and performs coordinate conversion for each point of the trajectory input by the user. For example, as shown in FIG. 11A, the point (A1, B1) in which both the x coordinate and the y coordinate are in the positive region (first quadrant) is subjected to the translation T and the rotation R, and FIG. It is moved to the position shown in (b). Next, with respect to the point (A1, B1), A1 is multiplied by the X-direction positive area expansion constant Mx1, and B1 is multiplied by the Y-direction positive area expansion constant My1, and the converted coordinates in the display device 6 are the positions shown in FIG. Is calculated as Then, the converted coordinates are displayed on the display device 6 (S6), and while the user operates the haptic device 2, S4 to S7 are repeated to convert and display each point.

  For example, for the points (A2, B2) where both the x coordinate and the y coordinate are in the negative region (third quadrant) as shown in FIG. The X-direction negative area expansion constant Mx2 and the Y-direction negative area expansion constant My2 are multiplied), and converted coordinates in the display device 6 are calculated as the positions shown in FIG. 11C and displayed on the display device 6.

Coordinate conversion rule selecting means for selecting. The selection of the coordinate conversion rule is performed by the user selecting the corresponding coordinate conversion rule on the screen of the display device 6 by operating the haptic device 2. For example, when a reference cross figure as shown in FIG. 12 (a) is determined, it is converted as shown in FIG. 12 (b) by translation and enlargement, and further enlarged as shown in FIG. 12 (c). Converted. The point (A3, B3) transformed according to such a coordinate transformation rule is shown as an example. The user can create and save his own coordinate conversion rule, and selects his own coordinate conversion rule when using the input device 1. The designated position coordinate conversion means converts the designated position coordinate in the reference coordinate system into the designated position coordinate in the virtual coordinate system in accordance with the selected coordinate conversion rule.

  Furthermore, the haptic device 2 is provided at a position where the haptic device 2 can be operated from a plurality of seats (see FIG. 3), and the coordinate conversion rule storage unit 53 (coordinate conversion rule storage means) has coordinate conversion corresponding to each of the plurality of seats. Rules are remembered. For example, when the reference cross figure of the passenger in the passenger seat as shown in FIG. 13A is determined, the points (A4, B4) are as shown in FIGS. 13B and 13C. Will be converted. It can also be configured to have a seat specifying means for specifying the coordinates at which the haptic device 2 is operated and to select a seat conversion rule corresponding to the specified seat. For example, as shown in FIG. 14B, the coordinate conversion rule is selected by selecting the corresponding coordinate conversion rule on the screen of the display device 6 by the user operating the haptic device 2. It can be constituted as follows.

  Alternatively, as shown in FIG. 15, infrared sensors 65 are provided on the driver seat side and the passenger seat side of the haptic device 2, and the infrared sensor 65 determines whether the operation is performed by the user on the driver seat side or the user on the passenger seat side. You may comprise so that it may determine.

  A case where master locus information other than a cross is output from the master locus information storage unit 56 in S12 of FIG. 7 will be described with reference to FIG. A circle or an ellipse can be used as the master trajectory information. In this case, when the master locus information is instructed from the coordinate conversion rule creation unit 55 to the master locus information storage unit 56, a circle (or an ellipse) is output to the output unit 57 as the master locus information. At this time, for example, “Draw a circle several times with the knob” is output by voice. Alternatively, as shown in FIG. 16A, a circular master locus may be displayed. However, in order to create a coordinate conversion rule from the user's operation stick, when the master trajectory is displayed, the user is not traced.

  As shown in FIG. 16B, the trajectory input from the haptic device 2 by the user is input to the coordinate conversion rule creation unit 55 and recorded as actual operation trajectory information. Then, as shown in FIG. 16C, it is approximated as a locus drawn in an ellipse from the user's eyelid, and the major axis and the minor axis are determined. The coordinate conversion rule creation unit regards the major axis and the minor axis as the X ′ axis and the Y ′ axis of the reference cross shape described above, performs the same translation, rotation, and enlargement, and translates T, R. The expansion constants Mx1, Mx2, My1, and My2 are stored in the coordinate conversion rule storage unit 56.

  In the above embodiment, the case where the position instruction is a two-dimensional coordinate system has been described. However, even if the position instruction is a one-dimensional coordinate system, the same conversion can be performed.
