Description

  The present invention relates to an operation device that receives an operation of a user by displaying an image such as a menu or an icon on a display panel such as a liquid crystal panel and detecting a contact operation on the image.

  2. Description of the Related Art Conventionally, an operation device that accepts a user operation by detecting a touch operation on a display panel, that is, a so-called touch panel type operation device has been widely used. Since the touch panel type operation device does not need to be provided with other buttons or switches, it is easy to downsize the operation device, and various operations can be accepted only by changing the image displayed on the display panel. There is an advantage that you can. In particular, in recent years, touch panels are often mounted on portable devices such as mobile phones, portable music players, and portable game machines, and technology development for improving the operability has been made.

  For example, in Patent Document 1, the position of a finger that touches the image display surface of a liquid crystal panel is detected by a touch panel, and an image is displayed in a region that does not reach the position of the finger that is in contact with the image display surface according to the detected contact position. There has been proposed an image display device that can change the image display area to a position that is not hidden by a finger by displaying.

  In recent years, a large number of electronic devices are mounted on vehicles, and an operation device for operating these devices is arranged near the driver's seat, for example, an instrument panel. As the number of devices increases and the number of devices increases, more switches or buttons are required to operate more functions, and a shortage of installation space is a problem. The touch panel type operation device is suitable for an operation device arranged in a limited space such as in a vehicle, and can solve the problem of insufficient arrangement space.

  In a conventional touch panel type operation device, for example, the user selects one item from a menu displayed in a list on the display panel by a touch operation, and the operation device that receives this selection updates the display content of the display panel. The user needs to perform a repetitive operation such as selecting one item from the updated menu by a touch operation, and the user can finally perform operations such as setting a target device by this repetitive operation. . Also, for example, when performing an operation to increase or decrease a numerical value such as changing the set temperature, the user changes the desired numerical value by performing a touch operation on the “+” or “−” icon displayed on the display panel several times. can do. However, an operating device that performs such an operation has a problem that its operability is low.

  In recent touch panel type operation devices, not only a simple touch operation on a display panel but also a slide operation for moving a finger touched by a user on the display panel, thereby changing an image displayed on the display panel. Things have been done. Accordingly, since the user can operate more intuitively, the operability of the touch panel type operation device can be improved.

JP 2005-234993 A

  However, in the touch panel type operation device described above, the user needs to perform an operation according to a predetermined operation procedure for one operation purpose such as changing the set temperature. Even with a touch panel type operation device that can perform an intuitive operation, the user must perform an operation according to a predetermined operation procedure, and the user's sensitivity does not match the intuitive operation. In some cases, the operability of the controller device may be further deteriorated.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a user with a plurality of operation procedures for one operation purpose, and to determine the number of contact points to the display panel. Accordingly, an object of the present invention is to provide an operating device that allows a user to perform operations in different ways.

An operating device according to the present invention is a control device including a display panel and a detection unit that detects a contact operation on the display panel, and determines the number of contact points on the display panel based on a detection result of the detection unit. When the contact number determining means and the detecting means detect a contact operation and the contact number determining means determines that the contact location is one location, a portion that moves with the linear movement of the contact location is determined. A straight line movement operation reception image is displayed on the display panel, and when the contact number determination means determines that there are a plurality of contact points, an arc movement operation reception having a portion that moves with the circular movement of the contact point a display processing unit that performs processing for displaying an image on the display panel, when the contact point is determined to be more than three places by the contact count determination unit, A estimating means for estimating the position of the hand in contact with the serial display panel, the linear movement operation receiving image and the arc moving operation receiving image has an index portion showing a state of operation reception, the display processing unit The index part of the linear movement operation acceptance image is displayed at a position other than the contact position with respect to the display panel, and the index part of the arc movement operation acceptance image is displayed outside the hand position estimated by the estimation means. It is characterized by the above.

The operating device according to the present invention is an operating device comprising a display panel and a detecting means for detecting a touch operation on the display panel. Based on a detection result of the detecting means, the number of touched portions on the display panel. When the contact number determination means and the detection means detect a contact operation and the contact number determination means determines that the contact location is one location, the contact location moves along with the linear movement of the contact location. A linear movement operation acceptance image having a portion is displayed on the display panel, and when the contact number determination means determines that the contact location is a plurality of locations, the arc movement having a portion that moves with the arc movement of the contact location Display processing means for performing processing for displaying an operation reception image on the display panel, and the linear movement operation reception image and the arc movement operation reception image are manipulated. The display processing means displays an indicator part of the linear movement operation acceptance image at a position other than the contact position with respect to the display panel, and the contact number determination means determines the contact location. When it is determined that there are three or more locations and the contact locations are located in an arc shape, the indicator portion of the arc movement operation acceptance image is displayed at a position outside the arc .

In the operation device according to the present invention, the display processing unit displays the linear movement operation reception image or the arc movement operation reception image so as to overlap at least one of the contact points with the display panel. It is characterized by that.

  In the operation device according to the present invention, the display processing unit displays one or a plurality of operation item images indicating operation items that can be received by a contact operation when the detection unit does not detect the contact operation. It is characterized by being displayed on a panel.

In the operation device according to the present invention, when the display processing unit displays a plurality of the operation item images on the display panel, the operation unit selects one operation item according to the position of the contact operation detected by the detection unit. The display processing means displays the linear movement operation reception image or the arc movement operation reception image related to the selected operation item, and reduces the operation item image related to the operation item not selected. It is characterized by being displayed.

In the operation device according to the present invention, when the display processing unit displays a plurality of the operation item images on the display panel, the operation unit selects one operation item according to the position of the contact operation detected by the detection unit. Receiving the receiving means, the display processing means displays the linear movement operation reception image or the arc movement operation reception image related to the selected operation item, and the operation item image related to the operation item not selected, The display is moved and displayed in a direction away from the contact point with respect to the display panel.

In the present invention, various operation images are displayed on a display panel such as a liquid crystal panel for image display, and the operation device accepts a user operation by detecting a touch operation on the display panel using a touch panel or the like. I do. When a contact operation is performed by the user, the operation device determines the number of contact locations on the display panel. If there is only one contact location, it can be estimated that the user is trying to perform a contact operation on the display panel with one finger such as an index finger. If there are a plurality of contact locations (2 to 5 locations), it can be estimated that the user is trying to perform a contact operation on the display panel with the entire hand (as if grabbed).
Therefore, the controller device displays different types of operation reception images on the display panel according to the number of contact points on the display panel, and receives different types of contact operations according to the displayed operation reception images. Accordingly, the operation device displays an operation acceptance image suitable for the contact mode on the display panel, and allows the user to perform an operation suitable for the contact mode. In other words, the user can change the operation method by changing the number of contact points on the display panel.

As described above, if there is only one contact location, it can be estimated that the user is performing a contact operation on the display panel with one finger. In this case, it is easy and intuitive for the user to perform an operation of moving the touched finger up and down or left and right of the display panel. Therefore, the operation device displays an operation reception image having a portion that moves in accordance with the linear movement of the contact location on the display panel, and receives an operation on the operation item according to the linear movement of the contact location. For example, an image of a slide bar is preferable as the reception image having a portion that moves along with the linear movement.
Further, as described above, if there are a plurality of contact locations, it can be estimated that the user is trying to perform a contact operation on the display panel with the entire hand. In this case, it is easy and intuitive for the user to perform a rotation operation for moving the contacted hand clockwise or counterclockwise. To do. Therefore, the operation device displays an operation acceptance image having a portion that moves with the arc movement of the contact location on the display panel, and accepts an operation on the operation item according to the arc movement of the contact location. For example, an image of a dial switch is preferable as the reception image having a portion that moves with the movement of the arc.

In the present invention, when an operation acceptance image is displayed by detecting contact with the display panel, the operation acceptance image is displayed so as to overlap at least one of the contact locations. In particular, it is desirable that an operation acceptance image having a portion that moves in accordance with the movement of the contact location is displayed with the moving portion superimposed on the contact location.
As a result, the controller device can prompt the user to operate the operation acceptance image, and further prompts the user to move the contact location on the display panel when moving parts are displayed in an overlapping manner. Can do.

As described above, if there are a plurality of contact locations, it can be estimated that the user is performing a contact operation on the display panel with a plurality of fingers of the hand. At this time, if there are three or more contact locations, the position (orientation) of the hand can be estimated from the arrangement.
Therefore, in the present invention, the position of the hand is estimated according to the contact location, and at least a part of the operation acceptance image is displayed at a position outside the hand. As a result, it is possible to prevent the operability from being deteriorated due to all of the operation acceptance images displayed on the display panel being hidden inside the hand.

  Further, when the user performs a contact operation with three or more fingers, it can be estimated that a plurality of contact points on the display panel are positioned in an arc shape. Therefore, in the present invention, at least a part of the operation acceptance image is displayed outside the arc formed by a plurality of contact locations. As a result, the operation acceptance image can be displayed at a position outside the hand of the user who performed the contact operation on the display panel, and all of the operation acceptance images displayed on the display panel are hidden inside the hand, thereby improving operability. It can be prevented from decreasing.

  In the present invention, when a contact operation is not performed on the display panel, an operation item image indicating items that can be received by the operation device by the contact operation is displayed on the display panel. Accordingly, the controller device can detect a contact operation on the operation item image displayed on the display panel and display an operation reception image for receiving an operation on this item on the display panel.

  In the present invention, the operation device displays a plurality of operation item images on the display panel, accepts selection of one operation item according to the detection result of the contact operation, and accepts an operation according to the selected operation item. Is displayed. At this time, the operating device reduces and displays the operation item images related to the other operation items that are not selected on the display panel. As a result, the user can easily recognize which operation item is selected by touch operation and which item is not selected, and the display panel area is displayed in order to display the operation reception image larger. Widely secured.

  In the present invention, the operation device displays a plurality of operation item images on the display panel, accepts selection of one operation item according to the detection result of the contact operation, and accepts an operation according to the selected operation item. Is displayed. At this time, the operation device moves and displays the operation item image related to the other operation items that are not selected in a direction away from the contact point with respect to the display panel.

FIG. 1 is a block diagram showing a configuration of an operating device according to the present invention. In the present embodiment, an operation device for operating an air conditioner (hereinafter simply referred to as an air conditioner) mounted on a vehicle will be described as an example, but the present invention is not limited to this.

  In the figure, reference numeral 1 denotes a display panel for displaying an image, which is arranged in the vicinity of a driver's seat such as an instrument panel of a vehicle. Specifically, the display panel 1 is configured by a liquid crystal panel, a PDP (Plasma Display Panel), or the like. A touch panel 2 for detecting a touch operation on the display panel 1 is disposed on the display surface of the display panel 1. That is, the operating device is a so-called touch panel type operating device that receives operations by the display panel 1 and the touch panel 2.

  The touch panel 2 is a resistive film type touch panel in which two films provided with a transparent resistance film are arranged to face each other and detect contact between the films due to pressing force, or an electric field generated by touching a user's finger. Various touch panels such as a capacitive coupling type touch panel that detects a change as a change in capacitance can be used.

  The operation device includes a contact detection unit 3 that detects a contact operation on the touch panel 2 based on an output voltage of the touch panel 2 and determines the number of locations where the contact operation has been performed, the contact position, movement of the contact position, and the like. Yes. The contact detection unit 3 notifies the control unit 6 of the detection and determination results. Further, the controller device includes an image processing unit 4 that generates an image to be displayed on the display panel 1 under the control of the control unit 6 and outputs the generated image as an image signal suitable for display on the display panel 1. ing.

  Specifically, the control unit 6 is configured by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like, and reads out and executes a program stored in the storage unit 5 to perform various arithmetic processes. And a process for controlling the operation of each part of the controller device. The storage unit 5 is configured by a non-volatile memory element such as a mask ROM (Read Only Memory), an EEPROM (Electrically Erasable Programmable ROM), or a flash memory, and is necessary for various programs executed by the control unit 6 and for execution. Various data are stored in advance.

  Further, the operating device includes a communication unit 7 that communicates with the air conditioner 9 and other devices (not shown) via a network such as a CAN (Controller Area Network) arranged in the vehicle. The communication unit 7 receives the data transmitted from the air conditioner 9 and gives it to the control unit 6. The control unit 6 judges the operation state of the air conditioner 9 from the given data and gives an instruction to the image processing unit 4 to display the data. The operating state of the air conditioner 9 can be displayed on the panel 1. When a touch operation is performed on the touch panel 2, the control unit 6 transmits an operation command from the communication unit 7 to the air conditioner 9 according to the operation content, and the air conditioner 9 that receives the operation command responds to the operation command (that is, (According to the contact operation).

  In a state where the touch operation is not performed on the touch panel 2, three operation item images 11 to 13 are displayed side by side in the horizontal direction of the display panel 1 on the display panel 1 of the operation device. The three operation item images 11 to 13 are respectively associated with three operation items of wind direction, air volume, and temperature that can be set by the user for the air conditioner 9, and include letters, numbers, icons, and the like. Are combined into a single operation item image 11-13.

  The operation item image 11 displayed on the left side corresponds to an operation item for setting the air direction of the air conditioner 9. The operation item image 11 includes a character string “MODE”, an icon imitating a person, an arrow, and the like, and the set wind direction is indicated by an arrow. The operation item image 12 displayed in the center corresponds to an operation item for setting the air volume of the air conditioner 9. The operation item image 12 is composed of a character string “BLOWER”, an icon imitating a windmill, an indicator for increasing / decreasing the number of square boxes in the left-right direction, and the set air volume is indicated by the number of boxes. Yes. The operation item image 13 displayed on the right side corresponds to an operation item for setting the temperature of the air conditioner 9. The operation item image 13 includes a character string “TEMP” and a number indicating the set temperature.

  In the case of performing a setting change operation for any of the operation items of the air direction, air volume, or temperature of the air conditioner 9, the user performs a touch operation on one of the operation item images 11 to 13 displayed on the display panel 1. By doing so, the setting change operation can be started. When the user performs a touch operation on the display panel 1, the touch operation is detected by the touch panel 2 and the touch detection unit 3 and notified to the control unit 6, and the control unit 6 detects the touch position and the operation item images 11 to 13. It is possible to determine which operation item has been selected as the operation target based on the display position. The operation item selection operation by the contact operation may be performed with one finger of the user or a plurality of fingers.

  2 and 3 are schematic diagrams for explaining the operation accepting method of the operating device according to the present invention. FIG. 2 shows a case where the user operates with one finger, and the operation is performed with a plurality of fingers. The case of performing is shown in FIG. 2 and 3, the operation for changing the temperature of the air conditioner 9 is shown.

  When the user performs a touch operation with one index finger on the operation item image 13 related to the temperature of the air conditioner 9 among the three operation item images 11 to 13 displayed on the display panel 1 (see FIG. 2A). ), The touch operation is detected by the touch panel 2 and the contact detection unit 3. The contact detection unit 3 determines the number of locations where the contact operation has been performed and the respective positions (coordinates) from the output signal of the touch panel 2 and notifies the control unit 6 that the contact operation has been performed. And the position thereof are notified to the control unit 6. In this example, there is one contact location, and the contact detection unit 3 notifies the control unit 6 of the location of this one location.

  The control unit 6 to which the notification from the contact detection unit 3 is given indicates that the operation item related to the temperature of the air conditioner 9 is selected by the contact operation because the position where the contact operation is performed overlaps the display position of the operation item image 13. judge. Further, since there is only one contact location, the control unit 6 gives an instruction to the image processing unit 4 to display the temperature setting operation acceptance image 20 so as to overlap the location where the contact operation has been performed. The selected operation item images 11 and 12 are displayed in a reduced size and moved in a direction away from the contact location (to the lower left side in the illustrated example) (see FIG. 2B).

  The operation acceptance image 20 is an image of a slide bar in which numerical values indicating temperatures are arranged at equal intervals in an oval region 21 that is long in the vertical direction of the display panel 1. The numerical value on the upper side is large and the numerical value on the lower side is small. Note that the operation acceptance image 20 is also an image imitating a thermometer. A set point 22 indicating the current set temperature is provided in the oval area 21 of the operation acceptance image 20, and the set point 22 displays a lead-out line outside the oval area 21 and the tip of this line. Set temperature values are provided. The control unit 6 displays the operation acceptance image 20 so that the set point 22 is above the position of the contact operation by the user (at least so that the set point 22 is not hidden by the user's finger).

  The set point 22 of the operation reception image 20 moves up and down in the oval area 21 in accordance with the vertical movement of the position of the finger of the user who performed the contact operation. That is, when the user linearly moves the contact location up and down, the contact detection unit 3 detects this and notifies the control unit 6 that the contact location has moved and the position (or movement amount) of the movement destination. The unit 6 gives an instruction to the image processing unit 4 to move the set point 22 up and down in accordance with the amount of vertical movement of the contact location, whereby the set point 22 moves up and down. The set temperature displayed at the end of the lead line of the set point 22 increases or decreases as the set point 22 moves up and down.

  Moreover, the control part 6 performs control which changes the setting of the temperature of the air-conditioner 9 according to the moving amount | distance of the up-down direction of a contact location. Specifically, the control unit 6 determines an increase / decrease amount of the temperature of the air conditioner 9 with respect to the amount of vertical movement of the contact location based on the notification from the contact detection unit 3, and a new temperature of the air conditioner 9 is determined based on the increase / decrease amount. The determined set value is transmitted from the communication unit 7 to the air conditioner 9 together with the temperature change command. Thereby, the operating device can receive an operation of changing the temperature of the air conditioner 9 by linear movement of the contact location with respect to the operation accepting image 20, and can perform control to change the temperature of the air conditioner 9 according to the received operation content.

  When the user performs a touch operation on the display panel 1 with a plurality of fingers (see FIG. 3A), the touch detection unit 3 determines the number of locations where the touch operation has been performed from the output signal of the touch panel 2. Each position is determined and notified to the control unit 6. The control unit 6 compares the positions of the plurality of places where the contact operation has been performed with the positions of the three operation item images 11 to 13 displayed on the display panel 1 to determine which operation item has been selected. . For example, among the operation item images 11 to 13 displayed on the display panel 1, the control unit 6 determines that the operation item related to the one operation item image 11 to 13 having the largest number of overlapping contact portions is selected. be able to. In addition, for example, the control unit 6 can determine that the operation item related to the operation item images 11 to 13 closest to the middle point of the plurality of contact locations has been selected. In this example, the control unit 6 determines that the five operation fingers of the hand are in contact with the operation panel 1 and the operation item of the temperature related to the operation item image 13 having the largest number of overlaps with the contact location is selected. .

  The control unit 6 displays the temperature setting operation acceptance image 30 on the display panel 1 by giving an instruction to the image processing unit 4 because the contact operation has been performed at a plurality of locations, and the non-selected operation item image. 11 and 12 are displayed in a reduced size and moved away from the contact location (see FIG. 3B). In addition, when displaying the operation acceptance image 30, the control unit 6 performs display so as to overlap at least one of the plurality of contact locations, estimates the position of the user's hand from the contact location on the display panel 1, and Is displayed at a position where the operation acceptance image 30 is not hidden by the hand (position outside the hand).

  For example, if there are three or more contact points when the hand is brought into contact with the display panel 1, the line connecting the contact points becomes an arc shape, so that the region on the center side (inner side) of the arc and the opposite side (outer side) The control unit 6 performs display so that a part of the operation reception image 30 is outside the arc. In addition, for example, when there are two contact points, or when there are three or more contact points but not in an arc shape, an operation is accepted above the contact point with respect to the display panel 1 (with respect to the display direction of the display panel 1). A part of the image 30 may be displayed.

  The operation acceptance image 30 is an image including an image imitating a substantially circular dial switch (hereinafter simply referred to as a dial switch 31) and an arc-shaped scale display 33 provided along the upper half circumference of the dial switch 31. . Further, an indicator portion 32 is provided at one peripheral portion of the dial switch 31 to indicate a current set temperature by pointing to one location on the memory display 33. The control unit 6 displays the operation acceptance image 30 so that the index unit 32 is not hidden by the user's hand.

  When the user rotates a hand with a plurality of fingers in contact with the display panel 1, the movement trajectory of the plurality of contact locations is arcuate. The operation acceptance image 30 is a range in which the position of the indicator portion 32 does not exceed the scale display 33 according to the rotation of the user's hand touching the display panel 1, that is, according to the arc movement of a plurality of contact locations on the display panel 1. As a result, the dial switch 31 is rotated, and the position of the indicator portion 32 is moved clockwise or counterclockwise. That is, when the user rotates his / her hand to move a plurality of contact points in an arc, the contact detection unit 3 detects this and indicates that the contact point has moved and the position of the destination (or the movement amount or rotation angle). Is notified to the control unit 6, and the control unit 6 instructs the image processing unit 4 to rotate the dial switch 31 according to the amount of movement of the contact location, and thereby the position of the index unit 32 is moved.

  Moreover, the control part 6 performs control which changes the setting of the temperature of the air-conditioner 9 according to the movement amount of a contact location. Specifically, the control unit 6 determines an increase / decrease amount of the temperature of the air conditioner 9 with respect to the movement amount of the contact location based on the notification from the contact detection unit 3, and a new set value of the temperature of the air conditioner 9 based on the increase / decrease amount. And the determined set value is transmitted from the communication unit 7 to the air conditioner 9 together with a temperature change command. Thereby, the operating device can receive an operation of changing the temperature of the air conditioner 9 by the circular movement of the contact location with respect to the operation receiving image 30, and can perform control to change the temperature of the air conditioner 9 according to the received operation content.

  FIG. 4 is a flowchart showing a procedure for receiving an operation performed by the operation device according to the present invention. First, the control unit 6 of the controller device determines whether or not a contact operation on the touch panel 2 has been detected according to the presence or absence of a notification from the contact detection unit 3 (step S1). (S1: NO), the display of the operation item images 11 to 13 on the display panel 1 is continued, and it waits until a contact operation is detected.

  When the contact operation is detected (S1: YES), the contact detection unit 3 determines the number of contact points (step S2), the control unit 6 acquires the number of arcs, and notifies from the contact detection unit 3 It is determined which of the operation item images 11 to 13 has been selected according to the position of the touched part (step S3). Next, the control unit 6 determines whether or not the number of contact locations determined by the contact detection unit 3 is one (step S4).

  When the number of contact points is one (S4: YES), the control unit 6 gives an instruction to the image processing unit 4 to reduce and display the operation item images 11 to 13 determined to be non-selected in step S2. And move to a position away from the contact location (step S5). Further, the control unit 6 displays an operation acceptance image 20 (see FIG. 2B) for accepting an operation by linear movement of the contact location so as to overlap the contact location (step S6), and proceeds to step S9.
