A GUI (Graphical User Interface) component is arranged in an easy arrangement (for example, see Patent Document 1).

JP-A-2006-184335

  According to the background art, when the vehicle is vibrating, the arrangement of the GUI components, for example, the buttons is adjusted, so that the operability is improved. However, even when the vehicle is not vibrating and the operator does not want to adjust the arrangement of the buttons, if the finger or the like is erroneously detected by the sensor, the arrangement of the buttons is adjusted.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a technique for arranging buttons according to an operator's intention.

  In order to solve the above-described problem, a display control device according to an aspect of the present invention includes an input unit that receives a detection result of presence / absence of a contact by an operator, and a plurality of input units that detect no contact. A control unit for displaying the button on the monitor in the first arrangement. When the detection result received by the input unit indicates that there is a contact, the control unit causes the monitor to display the plurality of buttons in a second arrangement different from the first arrangement.

  Another embodiment of the present invention also relates to a display control device. This device is a display control device for displaying a plurality of buttons on a monitor, a receiving unit for receiving an instruction of a setting mode for setting the arrangement of the plurality of buttons, and a monitor when the receiving unit receives the instruction.

FIG. 2 is a front view illustrating the electronic apparatus of FIG. 1. FIG. 3 is a diagram illustrating a configuration of the electronic device in FIG. 2. FIG. 3 is a diagram illustrating a first arrangement of a plurality of buttons on the monitor of FIG. 2.

  Before describing the present invention in detail, an overview will first be given. The present embodiment relates to an electronic device mounted on a vehicle and having a monitor with a touch function. The touch function is realized by, for example, a touch panel of an electromagnetic induction type / capacitance type. By touching a button displayed on the screen with a finger on the touch panel, an operator inputs an instruction assigned to the button to the electronic device. When such an electronic device is an in-vehicle navigation terminal device, its position is fixed substantially vertically, so that it is difficult for the operator to operate it. In particular, when the operator tries to press a button on the touch panel in a vehicle that is vibrating, the position of the finger may vibrate and the button may not be pressed well.

  In order to improve operability, a plurality of buttons are arranged based on the position of a finger or the like detected by a sensor arranged to surround the outside of the touch panel. However, even when the vehicle is not vibrating and the operator does not want to adjust the arrangement of the buttons, if the finger or the like is erroneously detected by the sensor, the arrangement of the buttons is adjusted. Therefore, it is desirable to arrange buttons according to the intention of the operator while improving the operability of the operator.

  To cope with this, the electronic device according to the present embodiment includes a sensor near the touch panel, for example, on the driver's seat side. This sensor is arranged at a position where the operator, who is the driver, can easily press the thumb. When the operator does not press the thumb against the sensor, that is, when the sensor does not detect a finger or the like, the electronic device displays a plurality of buttons on the touch panel in a first arrangement. In the first arrangement, for example, a plurality of buttons are arranged in a line. On the other hand, when the operator presses the thumb against the sensor, that is, when the sensor detects a finger or the like, the electronic device displays a plurality of buttons on the touch panel in the second arrangement. In the second arrangement, for example, a plurality of buttons are arranged on a substantially circular arc centered on the sensor. Thus, the plurality of buttons are arranged at a position where the operator can easily press the thumb with the index finger while pressing the thumb against the sensor. As described above, since the plurality of buttons are displayed by the second arrangement only when the operator presses the thumb on the sensor, the buttons are arranged according to the operator's intention of the operator.

  FIG. 1 is an external view of a vehicle compartment in which the electronic device 100 is mounted, as viewed from the rear. A driver's seat 206 is arranged on the right side, a passenger seat 208 is arranged on the left side, and a steering wheel 204 is arranged in front of the driver's seat 206 in front of the passenger compartment. In FIG. 1, the handle 204 and the driver's seat 206 are arranged on the right side, but they may be arranged on the left side. An instrument panel 202 is arranged in front of the handle 204, and a windshield 200 is arranged in front of the instrument panel 202. Furthermore, the electronic device 100 is installed on the side of the handle 204, for example, on the left center console. The electronic device 100 is a vehicle-mounted navigation terminal device, and an image of a car navigation system is displayed on a screen thereof.

  FIG. 2 is a front view showing the electronic device 100. The electronic device 100 includes a monitor 10, an outer frame 12, a sensor 20, and an operation unit 22. The monitor 10 has a rectangular shape and is arranged on the front side of the electronic device 100. The monitor 10 has a display function for providing information to the operator, and a touch panel function for determining the position touched by the operator and the period of touch. Since a known technique may be used for the monitor 10, the description is omitted here. However, in this embodiment, the monitor 10 displays a plurality of buttons as GUI parts.

  An outer edge frame 12 is arranged so as to surround the outer edge of the monitor 10. The sensor 20 is disposed on the right side of the outer edge frame 12, that is, on the side near the driver's seat 206 in FIG. At least one of the upper and lower sides of the sensor 20 in the outer edge frame 12 is provided with a projection or a depression, for example, as physical unevenness. When operating the monitor 10 with the left hand, the operator presses a finger other than the finger that operates the monitor 10, for example, a thumb, against the protrusion or the depression. Due to such pressing, the positional relationship between the electronic device 100 and the operator's left hand becomes constant, and the finger to be operated becomes stable. Therefore, the protrusion or depression or sensor 20 to which the thumb is pressed is also referred to as a reference point.

  When the operator presses the thumb against the protrusion or depression, the sensor 20 detects the contact of the operator's thumb. In FIG. 2, the sensor 20 is disposed on the right side of the monitor 10 assuming the right handle 204. However, when the left handle 204 is assumed, the sensor 20 may be disposed on the left side of the monitor 10. Further, the sensor 20 may be arranged above the monitor 10. Thus, the sensor 20 is arranged near the monitor 10. An operation unit 22 is disposed above the outer edge frame 12. The operation unit 22 is a button that can be pushed down by an operator.

  FIG. 3 shows a configuration of the electronic device 100. The electronic device 100 includes a monitor 10, a sensor 20, an operation unit 22, a display control device 30, a storage unit 32, and an operation reception unit. The display control device 30 includes an input unit 40, a control unit 42, a reception unit 44, and a detection unit 46, and the control unit 42 includes a setting unit 48. The monitor 10 includes a display unit 50 and a touch input unit 52. Here, the monitor 10 and the display control device 30 may be put together as a display device. Hereinafter, (1) basic operation and (2) setting operation will be described in this order.

(1) Basic Operation The sensor 20 detects contact by an operator, for example, the presence or absence of the operator's thumb. As the sensor 20, for example, an infrared sensor is used. The infrared sensor includes a light emitting unit that emits infrared light, and a light receiving unit that is arranged to correspond to the light emitting unit. When a finger passes directly above the infrared sensor, the infrared light transmitted from the light emitting unit is blocked by the finger and reflected. The light receiving unit detects the presence of the finger by receiving the reflected infrared light. In addition, microwaves may be used instead of the infrared sensor. In that case, a microwave is transmitted and a microwave that changes due to the approach of the finger is received, thereby determining whether or not a finger is directly above. The sensor 20 outputs a detection result to the input unit 40. Further, the sensor 20 may have a mechanical switch structure. In this case, the on state of the switch is recognized as contact by the operator.

  The input unit 40 receives a detection result from the sensor 20. The detection result indicates the presence or absence of contact by the operator. The input unit 40 outputs a detection result to the control unit 42. The storage unit 32 stores the coordinates of each button when displaying a plurality of buttons on the monitor 10 of FIG. Here, a different first arrangement and a second arrangement are defined as the arrangement of the plurality of buttons. The first arrangement and the second arrangement will be described later.

  The control unit 42 receives the detection result from the input unit 40. When the detection result indicates that there is no contact, the control unit 42 extracts the coordinates of each button in the first arrangement from the storage unit 32. Even if the detection result indicates that there is a contact, if the detection result does not continue for a predetermined time or longer, the control unit 42 may proceed with “no contact”. The control unit 42 arranges a plurality of buttons according to the extracted coordinates. FIG. 4 shows a first arrangement of the plurality of buttons 60 on the monitor 10. In the first arrangement, the first to fifth buttons 60a to 60e are arranged in a row in the horizontal direction. Here, the number of buttons 60 is not limited to “5”. Further, the plurality of buttons 60 may be arranged in a line in the vertical direction, or the buttons 60 may be arranged in the horizontal direction and the vertical direction. In the first arrangement, any of the plurality of buttons 60 is pressed by the index finger 70 without the thumb being pressed against the sensor 20. Referring back to FIG.

  On the other hand, when the detection result indicates that there is a contact, particularly when the contact has continued for a predetermined time or more, the control unit 42 extracts the coordinates of each button in the second arrangement from the storage unit 32. The control unit 42 arranges a plurality of buttons according to the extracted coordinates. FIG. 5 shows a second arrangement of the plurality of buttons 60 on the monitor 10. The monitor 10 shows an arc 62 centered on the sensor 20. The arc 62 is shown for clarity of the description and is not displayed on the monitor 10. The arc 62 is a part of the circumference around the sensor 20, but the circle may include an ellipse. Here, the circular arc 62 may be represented as a substantially circular arc, and “substantially” means including a difference of an error degree. In the second arrangement, a plurality of buttons 60 are arranged on the arc 62. This corresponds to arranging a plurality of buttons 60 at substantially the same distance from the sensor 20. In the second arrangement, one of the plurality of buttons 60 is pressed by the index finger 70 while the thumb 72 is pressed against the sensor 20. Referring back to FIG.

  After arranging the plurality of buttons 60 in the first arrangement or the second arrangement, the control unit 42 causes the display unit 50 of the monitor 10 to display the arranged plurality of buttons 60. As described above, the monitor 10 has a display function for providing information to the operator, and a touch panel function for determining the position where the operator has touched and the period during which the operator has touched. Here, the display unit 50 performs a display function, and the touch input unit 52 performs a touch panel function. The display unit 50 displays a plurality of buttons 60 arranged in the first arrangement or the second arrangement in the control unit 42 as a display function. That is, the display unit 50 displays the plurality of buttons 60 in the first arrangement when the detection result indicates that there is no contact, and displays the plurality of buttons 60 in the second arrangement when the detection result indicates that there is a contact. After the control unit 42 displays the plurality of buttons 60 on the display unit 50 according to the second arrangement, if the detection result changes without contact, the control unit 42 displays the plurality of buttons 60 on the display unit 50 according to the first arrangement. I do.

  The touch input unit 52 receives a touch operation performed by the operator on the monitor 10 as a touch panel function. Generally, the touch operation includes a flick operation, a pinch-in / pinch-out operation, and the like, but here, an operation of pressing the button 60 is shown. The touch input unit 52 outputs the content of the received touch operation, for example, the coordinates of the pressed button 60 to the operation receiving unit 34. Since a known technique may be used for the display function and the touch panel function, the description is omitted here.

(2) Setting Operation The setting operation is an operation for setting the arrangement of the plurality of buttons 60 in the second arrangement. Hereinafter, the mode for performing the basic operation described above is referred to as a “basic mode”, and the mode for performing the setting operation is referred to as a “setting mode”. When changing the basic mode to the setting mode, the operation unit 22, which is a button, for example, is pressed down by the operator. When detecting the depression, the operation unit 22 outputs an instruction of the setting mode to the reception unit 44. When receiving the setting mode instruction from the operation unit 22, the receiving unit 44 outputs the setting mode instruction to the control unit 42. Further, the operator presses a finger, for example, a thumb on the sensor 20 as in the case where the plurality of buttons 60 in the second arrangement are displayed on the display unit 50. The sensor 20 outputs the detection of the operator's thumb to the input unit 40 as a detection result. When receiving the detection result from the sensor 20, the input unit 40 outputs the detection result to the control unit 42.

  The control unit 42 shifts from the basic mode to the setting mode when the received detection result indicates that there is a contact and the setting mode instruction is received. Here, even if the control unit 42 does not receive the detection result, the control unit 42 may shift from the basic mode to the setting mode if it receives only the instruction of the setting mode. This corresponds to shifting to the setting mode if the operator presses down the operation unit 22 even if the operator's thumb is not pressed against the sensor 20. In the setting mode, the setting unit 48 sets the arrangement of the plurality of buttons 60 in the second arrangement. FIG. 6 is used here to specifically explain the setting. FIG. 6 shows an outline of the setting processing of the second arrangement. The operator presses the thumb 72 against the sensor 20 as in the case where the plurality of buttons 60 in the second arrangement are displayed on the display unit 50. The operator draws a substantially circular locus 64 while rotating the wrist about the thumb 72 while touching the monitor 10 with the index finger 70. The trajectory 64 is not limited to a substantially arc shape.

  The touch input unit 52 shown in FIG. 3 receives the input of the substantially circular locus 64, and the detecting unit 46 detects the substantially circular locus 64 input to the monitor 10. The detection of the substantially arc trajectory 64 corresponds to detecting a combination of coordinates included in the substantially arc trajectory 64. The detecting section 46 outputs the detected substantially circular locus 64 to the setting section 48. The setting unit 48 arranges a plurality of buttons 60 on a substantially circular locus 64. For example, the setting unit 48 arranges a plurality of buttons 60 on the locus 64 at equal intervals. The setting unit 48 sets the arrangement of the plurality of buttons 60 arranged as described above as the arrangement of the plurality of buttons 60 in the second arrangement. Referring back to FIG. The setting unit 48 stores the set arrangement of the plurality of buttons 60, for example, the coordinates of each button in the storage unit 32. The stored coordinates of each button are used as the second arrangement in the basic mode.

  In the setting mode, the setting unit 48 may change the size of the plurality of buttons 60 according to the distance between the sensor 20 and the trajectory 64. For example, the setting unit 48 increases the size of the button 60 as the distance increases. Such a relationship between the distance and the size of the button 60 may be stored in the storage unit 32.

  This configuration can be realized in terms of hardware by a CPU, a memory, or other LSI of an arbitrary computer, and is realized in software by a program or the like loaded in the memory. The functional blocks are drawn. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The operation of the electronic device 100 having the above configuration will be described. FIG. 7 is a flowchart showing a display procedure by electronic device 100. The input unit 40 receives the detection result (S10). When the detection result indicates that there is no contact (N in S12), the control unit 42 causes the display unit 50 to display the plurality of buttons 60 in the first arrangement (S14). If the detection result indicates that there is a contact (Y in S12), the control unit 42 causes the display unit 50 to display the plurality of buttons 60 in the second arrangement (S16).

  FIG. 8 is a flowchart illustrating another display procedure performed by the electronic device 100. When the receiving unit 44 receives the depression of the operation unit 22 (Y in S50), the input unit 40 receives the detection result (S52), and when the detection result indicates that there is a contact (Y in S54), the control unit. 42 shifts to the setting mode (S56). The detecting unit 46 detects the locus 64 on the monitor 10 (S58), and the setting unit 48 arranges a plurality of buttons 60 on the locus 64 (S60). The setting unit 48 causes the storage unit 32 to store the arrangement of the plurality of buttons 60 as the second arrangement (S62). Thereafter, the control unit 42 ends the setting mode (S64). If the receiving unit 44 does not receive the depression of the operation unit 22 (N in S50), or if the detection result indicates that there is no contact (N in S54), the processing is ended.

  According to the embodiment of the present invention, when the detection result indicates that there is no contact, a plurality of buttons are displayed on the monitor in the first arrangement, and when the detection result indicates that there is contact, the plurality of buttons are displayed on the monitor in the second arrangement. Since it is displayed, buttons can be arranged according to the operator's intention. Further, in the second arrangement, since a plurality of buttons are arranged on a substantially circular arc centered on the sensor, the operability of the operator can be improved. Also, since a plurality of buttons are arranged at positions where the index finger can be pressed while pressing the thumb against the sensor, operability can be improved.

  In the setting mode, the trajectory of the substantially circular arc input to the monitor is detected, and a plurality of buttons are arranged on the detected substantially circular trajectory. Therefore, the arrangement of the plurality of buttons is adjusted according to the size of the operator's hand. it can. In addition, since the arrangement of the plurality of buttons is adjusted according to the hand of the operator, the operability of the operator can be improved. Further, when a substantially circular locus is drawn on the monitor, the arrangement of the plurality of buttons is determined, so that the second arrangement can be easily set. Further, when the detection result indicates that there is a contact and the instruction of the setting mode is received, the mode is shifted to the setting mode, so that occurrence of an erroneous shift can be prevented.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and that such modifications are also within the scope of the present invention. .

  In the embodiment of the present invention, the sensor 20 is disposed near the monitor 10. However, the invention is not limited to this. For example, the sensor 20 may be arranged in the monitor 10. In this case, the sensor 20 is included in the touch input unit 52, and a part of the touch input unit 52 is used as the sensor 20. The portion may be fixed in advance or may be changeable by an operator or the like. According to this modification, the sensor 20 need not be provided separately from the touch input unit 52, so that the number of components can be reduced.
