Description:
TECHNICAL FIELD 
     The present invention relates to an in-vehicle apparatus including an image display section and a touch panel. 
     BACKGROUND ART 
     In recent years, it has become general to provide in-vehicle apparatuses having a car navigation system for guiding a route, a DVD playback feature, a CD playback feature in vehicles. 
     In such an in-vehicle apparatus, an image display section such as a liquid crystal display is provided near the driving seat in the vehicle interior to display, for example, a map around the current running position of the vehicle or various kinds of input setting screens on the image display section. Moreover, a larger image display section provides better visibility. For this reason, there is known a configuration in which mechanical buttons disposed around the image display section are reduced to provide a larger image display section while a touch panel is provided on the surface of the image display section. An operator performs an input operation to the in-vehicle apparatus by performing a touch operation, such as touching, flicking, or dragging on a part of the touch panel. 
     When an operator looks at an image display section for an operation or performs a detailed touch operation on a touch panel (e.g., operator looks at the section for more than two seconds), the operator no longer pays attention to the forward direction of the vehicle and his or her concentration on driving may decrease. Accordingly, it is not preferred to operate a touch panel while driving, for safety reasons. 
     Therefore, while the operator is driving, i.e., while the vehicle is running, operations for the in-vehicle apparatus are often restricted at a certain level in consideration of ensuring both safe driving and appropriate operationality of the in-vehicle apparatus. 
     As a conventional navigation apparatus, there is known an apparatus in which, upon detection of running of the vehicle, a touch area of a button displayed on a touch panel of the navigation apparatus is made larger in size than a touch area to be displayed while the vehicle is not running, in order to enhance the operability during driving (for example,. see PTL 1). 
     Moreover, there is also known a touch panel apparatus in which a display form of a display portion is changed in response to the running state and movement of the vehicle in order to ease the operation during driving (for example, see PTL 2).

     SUMMARY OF INVENTION 
     Technical Problem 
     However, in an in-vehicle apparatus including a conventional touch panel, an operator visually checks, for example, a button displayed on an image display section and performs an input operation by touching a desired position on the touch panel, such as a position where the button is displayed. Therefore, the in-vehicle apparatus including the conventional touch panel does not address the root cause of the problem, which is a situation where the need for the operator to look at the image display section causes the operator to pay no attention to the forward direction of the vehicle and the concentration of the operator on driving may be lowered. 
     Moreover, the in-vehicle apparatus including the conventional touch panel allows for an operation of only a function assigned to a button or the like displayed on the image display section. Therefore, in order to operate a function not displayed on the image display section, the operator first needs to switch a function displayed on the image display section. For this reason, the in-vehicle apparatus including the conventional touch panel involves complicated operations and need longer time. Thus, the in-vehicle apparatus including the conventional touch panel cannot avoid the problem, which is a situation where the operator pays no attention to the forward direction of the vehicle and the concentration of the operator on driving may decrease. 
     It is an object of the present invention to provide an in-vehicle apparatus that allows the operator to safely operate a function not displayed on the image display section with an easy operation without causing the operator to pay no attention to the forward direction of the vehicle due to the situation where the operator looks at the image display section while the vehicle is running. 
     Solution to Problem 
     In order to achieve the object described above, the present invention provides an in-vehicle apparatus including: an image display section that displays an image; a touch panel that is provided over the image display section and that detects information on a position touched by an operator; and a control section that recognizes an operation mode displayed on the image display section and a gesture inputted on the touch panel, and that determines, in accordance with a running state of the vehicle, to what operation mode the recognized gesture is performed as an operation, in which, when determining that the recognized gesture is performed as the operation to an operation mode other than the operation mode displayed on the image display section, the control section performs a function assigned to the gesture in the operation mode other than the operation mode displayed on the image display section. 
     Advantageous Effects of Invention 
     The present invention can determine that a gesture inputted from the touch panel is an operation made to an operation mode other than a displayed operation mode, in accordance with the running state of the vehicle. Therefore, the present invention provides advantageous effects that it is possible to easily perform an operation to an operation mode other than a displayed operation mode even during running of the vehicle and thus to reduce situations where the operator pays no attention to the forward direction of the vehicle.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, an in-vehicle apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings. 
     In the following description, however, the in-vehicle apparatus includes a touch panel and is exemplified and explained as an in-vehicle navigation apparatus. Therefore, this navigation apparatus including the touch panel is simply referred to as “an in-vehicle apparatus.” 
       FIG. 1  is a block diagram of the in-vehicle apparatus in the embodiment of the present invention. 
     In-vehicle apparatus  10  in the present embodiment includes, for example, a navigation function for guiding a route, an audio visual reproduction function reproducing an audio image recorded on recording media, such as DVD (Digital Versatile Disc). 
     In  FIG. 1 , in-vehicle apparatus  10  includes storing section  11 , external input section  12 , speaker  13 , image display section  17 , touch panel  18 , control section  20 , DVD/CD drive  22 , GPS receiver  23 , vehicle sensor  24 , gyroscope  25 , display mode switching section  31 , display mode recognition section  32 , gesture recognition section  33 , and operation mode determination section  34 . 
     However, DVD/CD drive  22 , GPS receiver  23 , vehicle sensor  24 , gyroscope  25 , and speaker  13  need not be provided integrally within in-vehicle apparatus  10 . These components may be each configured to be electrically detachable from in-vehicle apparatus  10 . Image display section  17  and touch panel  18  may be integrated in structure. 
     Storing section  11  is a data storing apparatus, such as an HDD, an SD card, and a flash memory implemented on a printed circuit board inside the in-vehicle apparatus, and a single kind or a plurality of kinds of storing apparatuses may be employed together. 
     Storing section  11  stores programs and databases. For example, the programs include a basic program necessary for controlling the icon size (the size of an icon, or the display region of the icon) and the icon layout displayed on image display section  17 , and operations of in-vehicle apparatus  10 . For another example, the programs include a program for controlling displaying of images, and application software used for executing a navigation function or executing an audio visual reproduction function. For example, the databases include a database on a map for navigation or a database for telephone numbers. 
     Moreover, storing section  11  includes, for example, a region for expanding various programs or various pieces of data and a region for expanding an image, similarly to a general storing section. 
     External input section  12  is provided in order to input a signal outputted from an external apparatus connectable to in-vehicle apparatus  10 , and can receive, for example, an image signal or an audio signal provided by reproducing media, such as a DVD and a CD, or an image signal or an audio signal from a digital television. 
     Speaker  13  is provided in order to output, for example, a sound effect for reporting to an operator that in-vehicle apparatus  10  has received an operation to in-vehicle apparatus  10 , sound inputted to external input section  12  from an external apparatus, or sound and music reproduced by DVD/CD drive  22  embedded inside in-vehicle apparatus  10 . 
     Image display section  17  is provided in order to display, for example, a menu screen or an opening screen stored in storing section  11 , or data of a still or moving image inputted from an external apparatus to external input section  12 . A typical liquid crystal display is provided as image display section  17  in the present embodiment. 
     That is, image display section  17  includes a liquid crystal panel, a back light unit, electric components, and a power supply unit. The liquid crystal panel includes, for example, a polarizing filter, a liquid crystal, a glass substrate, and a color filter. The back light unit is used for a light source for a liquid crystal panel, such as a cold cathode tube, an LED, and a light guide plate. The electric components are, for example, ICs controlling various signals for displaying images. The power supply unit is a power source for driving the liquid crystal, back light unit, and electronic components. However, the power supply unit may not be included in image display section  17  and may be provided as a separate unit. 
     Touch panel  18  is provided in the interior of or on the surface of image display section  17 , and is a transparent panel having a conductive layer. An input operation through touch panel  18  to in-vehicle apparatus  10  is performed by outputting, to control section  20 , information on a change in the amount of electrostatic capacitance generated by a touch operation (touching or approaching at a predetermined speed) on an applicable part displayed on image display section  17  and information on the operated position. For example, when an icon is displayed, the “applicable part” is the position of the icon displayed on the image display section. For another example, when a map is displayed, the “applicable part” is an arbitrary point displayed on the image display section. 
     Control section  20  includes a microprocessor and an electrical circuit for operating the microprocessor, executes a control program stored by storing section  11 , and performs various kinds of control processes. Control section  20  also performs a control process so as to display image data obtained as a result of these control processes on the image display section  17 . 
     Control section  20  includes display mode switching section  31 , display mode recognition section  32 , gesture recognition section  33 , and operation mode determination section  34 . 
     The term “operation mode” refers to a function such as a navigation function, a CD playback function, or an image signal display function with respect to an external apparatus, which is executed by in-vehicle apparatus  10 . 
     Display mode switching section  31  is provided in order to switch a function displayed on image display section  17 . For example, the display mode is a navigation mode when a map for route guidance of the navigation function is displayed on image display section  17 . Meanwhile, the display mode is a CD playback mode in the case of displaying, for example, the album name and song title of a CD being played back, and operation icons for CD playback, such as a volume control, playback, and stop. Display mode switching section  31  switches between the displaying of a map in the navigation mode, and the displaying of the album name and the song title of a CD, and operation icons for CD playback, such as a volume control, playback, and stop in the CD playback mode. 
     Display mode recognition section  32  is provided in order to recognize a function displayed on image display section  17 . 
     Gesture recognition section  33  is provided in order to recognize a gesture such as a flicking on the basis of a time transition in a signal for a touch position outputted from touch panel  18  to control section  20 . 
     Operation mode determination section  34  is provided in order to determine an operation mode to be performed, by the gesture recognized in gesture recognition section  33 . 
     Moreover, control section  20  may include one microprocessor or may include a plurality of microprocessors for respective functions such as DVD playback and audio playback. 
     DVD/CD drive  22  is provided in order to play back a disk storing an audio source (or audio data) and an image source (or image data). 
     GPS receiver  23  is provided in order to receive a signal from a GPS satellite. 
     Vehicle sensor  24  is provided in order to receive a vehicle speed signal and a parking brake signal from a vehicle and to determine a vehicle state such as the moving speed of the vehicle and the state of the parking brake. 
     Gyroscope  25  is provided in order to detect the amount of rotation, a variation in vertical movement and the acceleration of a vehicle. 
     Detailed operations of in-vehicle apparatus  10  configured in the manner described above will be explained below with reference to  FIGS. 2 to 5 . 
       FIG. 2  is a simple perspective view illustrating an example placement inside a vehicle for explaining how to use in-vehicle apparatus  10  in the embodiment of the present invention. 
     In-vehicle apparatus  10  in the embodiment of the present invention is attached to the center console of a vehicle, and an operator touches touch panel  18  provided on image display section  17  with finger  60  to perform an input operation. 
     Speaker  13  is attached inside the vehicle. 
     Next, the operations of in-vehicle apparatus  10  in the present embodiment will be explained. 
     In in-vehicle apparatus  10  in the present embodiment, operation mode determination section  34  determines an operation mode to be performed by gesture inputted by an operator. In order to assist in understanding this explanation, with reference to  FIGS. 3A to 3D , negative effects will be first described, which may occur when operation mode determination section  34  does not determine an operation mode to be performed by gesture inputted by the operator, i.e., when gesture inputted from the operator is performed for an operation mode always displayed. 
     As illustrated in  FIG. 3A , image display section  17  displays a map for the navigation function, icons  40  for enlarging or reducing the map, and display mode change icon  50  for changing a function displayed on image display section  17 . 
     Meanwhile, speaker  13  outputting music is schematically illustrated in order to illustrate that in-vehicle apparatus  10  also performs the CD playback function at the same time. That is, in-vehicle apparatus  10  performs the two modes that are the navigation mode and the CD playback mode. 
     Since the map and icon  40  for the navigation mode are displayed on image display section  17  at this time, display mode recognition section  32  recognizes that the display mode is the navigation mode. 
       FIG. 3B  illustrates that the operator performs gesture input for rightward flicking on touch panel  18  with finger  60  when the CD playback mode is performed and when the display mode is the navigation mode. 
       FIG. 3C  illustrates an example operation in a case where gesture input for rightward flicking is performed on touch panel  18  of in-vehicle apparatus  10  executing the CD playback mode while the display mode is the navigation mode, when control section  20  determines that the vehicle is stopping on the basis of a signal from vehicle sensor  24 . 
     Since the gesture for rightward flicking is an operation for the navigation mode as the display mode, control section  20  performs an operation for rightward scrolling of the map assigned to rightward flicking in the navigation mode.  FIG. 3C  illustrates rightward scrolling of the map in the navigation mode displayed on image display section  17  in  FIG. 3B . 
       FIG. 3D  illustrates an example operation in a case where gesture input for rightward flicking is performed on touch panel  18  of in-vehicle apparatus  10  executing the CD playback mode while the display mode is the navigation mode, when control section  20  determines that the vehicle is running on the basis of a signal from vehicle sensor  24 . 
     A scrolling operation for the map while the vehicle is running may cause the operator to pay no attention to the forward direction of the vehicle and is therefore not preferred. Therefore, control section  20  disables the scrolling operation on the map screen while the vehicle is running. 
     The gesture for rightward flicking is an operation for the navigation mode as the display mode, but control section  20  disables scrolling of the map in response to gesture in consideration of safety of the operator. As a result, as illustrated in  FIG. 3D , the displaying state of the map in  FIG. 3B  does not change in the navigation mode as the operation mode. 
     Here, let us consider a case where the volume of sound outputted from speaker  13  in the CD playback mode is controlled through an operation on touch panel  18  for in-vehicle apparatus  10  executing the two operation modes that are the navigation mode and the CD playback mode and executing the navigation mode as the display mode. 
     Since a volume control icon is not displayed on image display section  17 , the operator need to perform a touch operation on touch panel  18  a plurality of times, for example, touching the position of display mode change icon  50  so as to display the volume control icon on image display section  17 , changing the display mode, and operating a desired icon. 
     In this way, in order to control the volume, the display mode is switched, an icon having a desired function is displayed, and a touch operation is performed at the position of an icon having a desired function. Such complicated operations cause the operator to pay no attention to the forward direction of the vehicle. 
     In this respect, in-vehicle apparatus  10  in the present embodiment switches an operation mode for performing gesture input by the operator. This avoids complicated operations, such as performing a touch operation on icons a plurality of times, and enables a desired operation through one time of gesture input on whole touch panel  18  having a larger area than the icon, thus improving the safety. 
     Example operations of in-vehicle apparatus  10  will be explained in the case of switching an operation mode for performing gesture input by the operator, with reference to  FIGS. 4A to 4D . 
     As illustrated in  FIG. 4A , image display section  17  displays a map for the navigation function, icons  40  for enlarging or reducing the map, and display mode change icon  50  for changing a function displayed on image display section  17 . 
     Meanwhile, speaker  13  outputting music is schematically illustrated in order to illustrate that in-vehicle apparatus  10  also performs the CD playback mode at the same time. 
     Since the map and icon  40  for the navigation mode are displayed on image display section  17  at this time, display mode recognition section  32  recognizes that the display mode is the navigation mode. 
       FIG. 4B  illustrates that the operator performs gesture input for rightward flicking on touch panel  18  with finger  60  when the CD playback mode is executed and when the display mode is the navigation mode. 
       FIG. 4C  illustrates an example operation in a case where gesture input for rightward flicking is performed on touch panel  18  of in-vehicle apparatus  10  executing the CD playback mode while the display mode is the navigation mode, when control section  20  determines that the vehicle is stopping on the basis of a signal from vehicle sensor  24 . 
     Image display section  17  displays the map in the navigation mode, and display mode recognition section  32  recognizes that the display mode is the navigation mode. 
     Since the vehicle is stopping, operation mode determination section  34  determines that gesture for rightward flicking in  FIG. 4B  is an operation for the navigation mode as the display mode. Control section  20  then performs an operation for rightward scrolling of the map assigned to rightward flicking in the navigation mode. As illustrated in  FIG. 4C , the map in the navigation mode displayed on image display section  17  in  FIG. 4B  is scrolled rightward. 
       FIG. 4D  illustrates an example operation in a case where gesture input for rightward flicking is performed on touch panel  18  of in-vehicle apparatus  10  executing the CD playback mode while the display mode is the navigation mode, when control section  20  determines that the vehicle is running on the basis of a signal from vehicle sensor  24 . 
     Image display section  17  displays the map in the navigation mode, and display mode recognition section  32  recognizes that the display mode is the navigation mode. 
     Since the vehicle is running, operation mode determination section  34  determines that the gesture for rightward flicking is not an operation for the navigation mode as the display mode and determines the gesture to be an operation for the CD playback mode being executed although the CD playback mode is not displayed on image display section  17 . 
     Control section  20  performs increasing of the volume, which is a function assigned to the gesture for rightward flicking in the CD playback mode.  FIG. 4D  schematically illustrates that the output volume from the speaker  13  increases. 
     That is, even during running of the vehicle, it is made possible to perform an operation for a function not displayed on the screen, by an easy operation, i.e., easy gesture for rightward flicking without impairing the safety, instead of a plurality of input operations for touching display mode change icon  50 . 
     Next, the operations of in-vehicle apparatus  10  will be explained with reference to  FIG. 5 . 
     A state where nothing touches touch panel  18  is defined as the start of operations (the start state in  FIG. 5 ). 
     Control section  20  determines whether the vehicle is running or stopping on the basis of a signal from vehicle sensor  24  (Step S 10 ). That is, based on the signal of the parking brake from vehicle sensor  24 , control section  20  determines that the vehicle is running (YES in Step S 10 ), when the parking brake is turned off. 
     When determining that the vehicle is running, control section  20  restricts, for example, input operations of the operator, such as scrolling of the map and searching for a destination, or restricts displaying of the icons for input operations restricted during the running of the vehicle (Step S 11 ). 
     Control section  20  detects information outputted from touch panel  18  when the operator touches touch panel  18  (Step S 12 ). That is, control section  20  detects that the operator has performed an input operation on touch panel  18 . 
     When control section  20  detects the input of the operator on the basis of information from touch panel  18 , gesture recognition section  33  determines whether the touch input operation is made to a specific place, such as a place for displaying an icon, or a gesture input operation is performed, on the basis of a time transition of the signal of the touch position outputted from touch panel  18  to control section  20  (Step S 13 ). That is, if a time transition of the signal of the touch position outputted from touch panel  18  to control section  20  is larger than a predetermined value, gesture recognition section  33  determine that gesture input operation is performed (YES in Step S 13 ). 
     Gesture recognition section  33  recognizes the gesture performed by the operator on the basis of a time transition of the signal of the touch position outputted from touch panel  18  to control section  20 , and determines whether the recognized gesture is a specific gesture assigned to performing of a function restricted in control section  20  (Step S 14 ). 
     When gesture recognition section  33  determines that the recognized gesture is this specific gesture (YES in Step S 14 ), control section  20  determines whether a plurality of operation modes are executed in in-vehicle apparatus  10  (Step S 15 ). More specifically, control section  20  determines whether the operation mode performed in in-vehicle apparatus  10  is only the operation mode recognized by display mode recognition section  32 , or any operation mode other than this recognized operation mode is also performed. 
     When control section  20  determines that a plurality of operation modes are executed in in-vehicle apparatus  10  (YES in Step S 15 ), operation mode determination section  34  determines that the gesture recognized by gesture recognition section  33  is an operation to an operation mode other than the display mode, and performs a function assigned to gesture in the operation mode other than the display mode (Step S 16 ). 
     Meanwhile, in any one of the three cases described below, operation mode determination section  34  determines that the gesture recognized by gesture recognition section  33  is an operation to the display mode (Step S 17 ). The first is a case where gesture recognition section  33  determines that gesture input operation is not recognized (NO in Step S 13 ). The second is a case where gesture recognition section  33  recognizes the gesture as a gesture input operation, and where the gesture is determined not to be a specific gesture assigned to performing of a function restricted in control section  20  (NO in Step S 14 ). The third is a case where the gesture is recognized as specific gesture, and where control section  20  determines that the operation mode performed in in-vehicle apparatus  10  is only the operation mode recognized by display mode recognition section  32  (NO in Step S 15 ). Additionally, since the gesture is assigned to performing of a function restricted in control section  20  when the operation to the display mode is a gesture recognized by gesture recognition section  33 , the gesture operation is made invalid. On the other hand, when the operation to the display mode is a touch input operation to a specific place, such as a place for displaying an icon (NO in Step S 13 ), control section  20  performs a function assigned to the place touched by the operator or a function assigned to the icon displayed on the touched place (Step S 17 ). 
     Moreover, when the parking brake is turned on, control section  20  determines that the vehicle is stopping (NO in Step S 10 ) on the basis of the signal of the parking brake from vehicle sensor  24 . 
     When determining that the vehicle is stopping, control section  20  does not restrict, for example, input operations of the operator, such as scrolling of the map and searching for a destination, or does not restrict displaying of the icons for input operations restricted during the running of the vehicle (Step S 21 ). 
     Control section  20  detects information outputted from touch panel  18  in response to the operator touching touch panel  18  (Step S 22 ). That is, control section  20  detects that the operator performs an input operation on touch panel  18 . 
     When control section  20  detects the input of the operator on the basis of information from touch panel  18 , gesture recognition section  33  determines whether the touch input operation is made to a specific place, such as a place for displaying an icon, or a gesture input operation is performed, on the basis of a time transition of the signal of the touch position outputted from touch panel  18  to control section  20  (Step S 23 ). 
     If gesture recognition section  33  determines that a time transition of the signal of the touch position outputted from touch panel  18  to control section  20  is larger than a predetermined value and that the input of the operator is a gesture input operation (YES in Step S 23 ), the following operation is performed. That is, operation mode determination section  34  determines that the gesture recognized by gesture recognition section  33  is an operation to the display mode, and performs a function assigned to gesture in the display mode (Step S 24 ). 
     When gesture recognition section  33  determines that a time transition of the signal of the touch position outputted from touch panel  18  to control section  20  is smaller than a predetermined value and that the input of the operator is a touch input operation to a specific place, such as a place for displaying an icon (NO in Step S 23 ), the following operation is performed. That is, control section  20  performs a function assigned to the place touched by the operator or a function assigned to the icon displayed on the touched place (Step S 25 ). 
     As described above, according to the present embodiment, it is possible to perform an operation to a not display operation mode with a single operation of gesture assigned to performing of a function restricted during the running of the vehicle. As a result, it is no longer necessary, for example, to switch the display mode or perform an input operation a plurality of times in order to display the icon assigned to a desired function. This can provide both a reduction in factors causing the operator to pay no attention to the forward direction of the vehicle and the securement of operability. Meanwhile, an icon that allows a desired operation to be performed by a single operation does not have to be always displayed on image display section  17  because a gesture input is used. This can ensure the visibility of image display section  17 . 
     Meanwhile, as to determination of whether the vehicle is running or stopping, the vehicle may be determined to be stopping when the vehicle speed calculated from a vehicle speed signal of vehicle sensor  24  is equal to or less than a predetermined value. In this case, situations such as running or stopping of the vehicle or the like can be determined more surely in comparison with determination based on only the state of the parking brake. 
     In the present embodiment, rightward flicking is used as an example gesture input of the operator, but leftward flicking or flicking in the vertical direction may be used as well. In this case, operations to a not displayed operation mode are made possible, the operations including rightward flicking for increasing the volume, leftward flicking for decreasing the volume, upward flicking for restarting playback of a song currently played on a CD, downward flicking for starting playback of a song subsequent to the song currently played on the CD, for example. As a result, the usability is improved. 
     Furthermore, a gesture assigned to performing of a function restricted during running of the vehicle may be flicking with a plurality of fingers or other gestures. In this case, the operator does not need to learn a new gesture for an operation to an operation mode other than the display mode.
