Description

  The present invention relates to a touch panel type operation device that receives a user's operation by displaying an operation image such as a menu or an icon on an image display unit and detecting a contact operation on the operation image with a touch panel.

  2. Description of the Related Art Conventionally, touch panel type operation devices that accept user operations by providing a touch panel on the display surface of an image display unit have 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 reduce the size of the operation device and accept various operations only by changing the image displayed on the image display unit. There is an advantage that can be done. In particular, the touch panel type operation device is suitable for an operation device disposed in a limited space such as in a vehicle.

  In Patent Document 1, a pressing operation performed on a transparent touch panel disposed on an upper portion of a liquid crystal display unit is detected, and when the pressing operation is detected, the vibration unit is driven to transmit vibration to the fingertip. A touch panel type input device has been proposed. This touch panel type input device can improve operability because key touch can be confirmed by vibration, and can provide a user interface other than a display screen and sound in a portable game machine having a touch panel.

Patent Document 2 proposes a touch panel holding frame and a spacer member that can easily position and fix the touch panel with respect to the display device body, and a display device using these. In this display device, the first position surrounding portion of the touch panel holding frame is fitted so as to surround the outer peripheral portion of the display device main body on the display screen side, and the second position determining portion surrounds the outer peripheral portion of the touch panel. It is fitted outside. A holding claw portion formed on the inner surface side of the second position determining portion prevents and locks the outer peripheral portion of the touch panel.

  FIG. 11 is a schematic cross-sectional view showing a configuration of a conventional touch panel type operation device. In the figure, reference numeral 101 denotes a display panel. On the display surface of the display panel 101, a touch panel 102 is disposed with a predetermined interval by a spacer member 103. Moreover, the peripheral part of the surface of the touch panel 102 is covered with the frame member 104 which is a part of the housing of the operating device. The operation device displays operation images 101a and 101b such as buttons or icons for operation on the display panel 101, and detects a user's contact operation on the operation images 101a and 101b on the touch panel 102.

  A touch panel type operation device mounted on a vehicle is often disposed between a driver seat and a passenger seat in an instrument panel at the front of the vehicle, and a user sitting in the driver seat or the passenger seat can display the display panel 101. In many cases, the contact operation is performed on the display surface from an oblique direction. In the touch panel type operation device, the parallax due to the influence of the distance between the display panel 101 and the touch panel 102 by the spacer 103 and the thickness of the touch panel 102 is taken into consideration for the operation images 101 a and 101 b displayed on the display panel 101. It is necessary to enlarge the detection areas 102a and 102b of the touch panel 102.

For example, when the distance between the display panel 101 and the touch panel 102 is d1, the thickness of the touch panel 102 is d2, and the user performs a contact operation from an oblique angle of θ ° as shown in the figure, the following (Formula 1) is calculated. The detection areas 102a and 102b must be larger than the operation images 101a and 101b on the left and right by the distance of the width h.
h = (d1 + d2) tan θ (Expression 1)

  In order to make the detection areas 102a and 102b of the touch panel 102 larger than the operation images 101a and 101b displayed on the display panel 101, it is necessary to sufficiently increase the distance between the plurality of operation images 101a and 101b displayed on the display panel 101. There is. For this reason, the number of operation images 101a and 101b to be displayed on the display panel 101 is limited, and in order to display more operation images 101a and 101b, each 101a and 101b must be made smaller. There is a problem that the sex gets worse. An operation device having a larger distance d1 between the display panel 101 and the touch panel 102 and a thickness d2 of the touch panel 102 is more likely to cause this problem.

  Further, in the touch panel type operation device, the user needs to touch the image display unit with a finger or the like during operation, and part of the image display unit is hidden by touching the finger or the like. There is a problem that the nature is bad. In particular, when a plurality of small operation images are displayed side by side on the image display unit, a plurality of operation images are hidden by a user's finger or the like by a contact operation on one operation image, and the user performs a contact operation on any operation image. Therefore, it is difficult to recognize whether the controller device has been received by the controller device, so that the operability of the controller device deteriorates. These problems cannot be solved by the touch panel type input device described in Patent Document 1 and the display device described in Patent Document 2.

  The present invention has been made in view of such circumstances, and the object of the present invention is to reduce the operability even when, for example, a plurality of small operation images are displayed close to each other on the image display unit. An object of the present invention is to provide a touch panel type operation device that does not need to be performed.

  An operation device according to the present invention is provided to cover an image display unit, display processing means for performing processing for displaying a plurality of operation images for accepting operations on the image display unit, and a display surface of the image display unit. A touch panel that detects a touch operation, and a specifying unit that specifies one operation image to be operated from a plurality of operation images displayed on the image display unit based on a detection result of the touch panel, and the display processing The means is characterized in that the one operation image specified by the specifying means is enlarged and displayed as compared with the other operation images.

  In the present invention, a plurality of operation images such as buttons or icons for receiving an operation are displayed on the image display unit, and a touch operation on the operation image displayed on the image display unit is detected by the touch panel. In order to display many operation images on the image display unit and secure a wide detection area of the touch panel in consideration of the influence of parallax, the display size of the operation image must be reduced. Even in such a case, the operation device of the present invention checks which operation image is a contact operation among a plurality of displayed operation images based on the detection result of the touch panel, and determines one of the operation objects. The specified operation image is specified, and the specified one operation image is enlarged and displayed as compared with the other operation images. As a result, the visibility of the operation image to be operated can be improved, and the user can easily recognize which operation image the contact operation has been received by the operation device.

  The operation device according to the present invention is characterized in that the display processing means performs an enlarged display so that the one operation image is gradually enlarged.

  In the present invention, when one operation image specified as an operation target is enlarged and displayed, the operation device performs enlarged display so that the one operation image gradually becomes larger. That is, the operating device enlarges and displays one operation image by animation display. As a result, the user can more reliably recognize which operation image is the operation target.

  In the operation device according to the present invention, the display processing unit displays a spherical image as the operation image, and displays a recessed spherical image as the one operation image specified by the specifying unit. It is characterized by that.

  In the operating device according to the present invention, the display processing unit displays a bright circle image at the center as the operation image, and a dark circle image at the center as the one operation image specified by the specifying unit. It is characterized by being displayed.

In the present invention, a spherical image is displayed on the image display unit as the operation image. When a contact operation is performed by the user, an image of a recessed sphere is enlarged and displayed as one operation image of the operation target. Thereby, the user can be given an image of crushing the sphere displayed on the image display unit by a contact operation, and the operability of the operating device can be improved.
In addition, by displaying an image with a bright circle at the center as an operation image and displaying an image with a dark circle at the center as one operation image to be operated, the image is the same as when displaying an image of a sphere and a recessed sphere. The effect of can be obtained.

  The operation device according to the present invention may be configured such that when the display processing unit enlarges and displays the one operation image, the one operation image overlaps with the other operation image. Is displayed with priority.

  In the present invention, when a plurality of operation images are displayed side by side on the image display unit, if one operation image to be operated is enlarged and displayed, there is a possibility that the enlarged one operation image and other surrounding images overlap. . In such a case, even if the operation images are overlapped by preferentially enlarging and displaying the one operation image that is the operation target, that is, by enlarging and displaying the one operation image on the other operation image. The user can surely recognize which operation image is the operation target.

  The operation device according to the present invention is characterized in that the display processing means enlarges and displays the one operation image so as to be larger than a circle having a diameter of 18 mm.

  In the present invention, the operation device performs an enlarged display of one operation image so that one operation image after enlargement becomes larger than a circle having a diameter of 18 mm. This is because the thickness of the index finger of an adult male is about 17 mm to 18 mm, and the user's index finger is in contact with the image display unit by displaying one operation image larger than a circle having a diameter of 18 mm. This is because the enlarged operation image is not completely covered by the index finger.

  In the operation device according to the present invention, the display processing unit enlarges and displays an operation image whose color or brightness gradually changes outward with the contact operation position on the touch panel as a center. It is characterized by.

  In the present invention, the touch operation position to the image display unit is acquired when the touch panel detects the touch operation to the image display unit. In the case of enlarging and displaying one operation image related to this contact operation, an operation image in which the color or brightness gradually changes outwards with the acquired contact operation position as the center is displayed in an enlarged manner. For example, in a liquid crystal image display unit, when a user's finger or the like touches the display surface of the image display unit, the contact part of the image display unit and its surroundings are distorted and the display color changes, and the visibility of the image display unit changes. May decrease. Thus, by displaying an enlarged operation image whose display color has been changed in advance with the contact operation position on the image display unit as the center, it is possible to suppress a reduction in visibility due to a change in display color due to contact.

  In addition, the operation device according to the present invention further includes vibration generating means for applying vibration to the image display unit when the touch panel detects a contact operation.

  In the present invention, when the touch panel detects a touch operation on the image display unit, the operation device gives vibration to the image display unit. Thus, the user can easily and reliably recognize that the contact operation has been received by the operation device.

  According to the present invention, among the plurality of operation images displayed on the image display unit, one operation image to be operated is specified from the detection result of the touch panel, and the specified one operation image is displayed larger than the other operation images. With this configuration, the user can easily recognize which operation image the contact operation has been accepted by visually recognizing the enlarged operation image. Therefore, it is possible to realize a touch panel type operation device that can display a plurality of small operation images close to the image display unit without deteriorating operability.

  Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof. FIG. 1 is a block diagram showing a configuration of an operating device according to the present invention. In the figure, reference numeral 1 denotes an operating device, which is a device that accepts user operations on devices such as a car navigation device 5, an audio device 6 and an air conditioner (hereinafter referred to as air conditioner) device 7 mounted on a vehicle (not shown). is there. The operating device 1 includes a display panel 20 disposed on an instrument panel provided at a front portion in the vehicle, and a touch panel 30 disposed on a display surface of the display panel 20 to detect a contact operation by a user. Is a so-called touch panel type operation device.

  The display panel 20 is a liquid crystal panel, a PDP (Plasma Display Panel), or the like, and displays various images (operation images) for the user to operate devices such as the car navigation device 5, the audio device 6, and the air conditioner device 7. . The operation image displayed on the display panel 20 is, for example, a menu or icon for selecting an operation target, starting / stopping an operation, or changing a setting value related to the operation. The user can operate these devices by touching the operation image displayed on the display panel 20.

  The touch panel 30 is a resistive film type touch panel in which two films or the like provided with a transparent resistance film are arranged to face each other to 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 1 also stores a drawing unit 14 that performs processing for displaying various images on the display panel 20, a position acquisition unit 15 that acquires the position of a contact operation based on the output of the touch panel 30, and various data. The communication unit 13 that transmits and receives data to and from the storage unit 12 and other devices in the vehicle, and the control unit 11 that controls the operation of each unit. The storage unit 12 includes a ROM (Read Only Memory) or a nonvolatile memory element, and stores various programs and data in advance. The storage unit 12 stores data related to an image displayed on the display panel 20.

  The communication unit 13 is connected to a network cable or the like arranged in the vehicle, and transmits and receives data according to a predetermined protocol such as CAN (Controller Area Network). The content of the operation by the user accepted by the controller device 1 is notified from the communication unit 13 to each device. Further, the communication unit 13 receives information such as the operation state of each device and gives the information to the control unit 11, whereby the control unit 11 can display the operation state of each device on the display panel 20.

  The drawing unit 14 performs drawing on the display panel 20 by generating an image to be displayed on the display panel 20 under the control of the control unit 11 and outputting the generated image as an image signal to the display panel 20. The drawing unit 14 can read and display a necessary image from the storage unit 12 when displaying an image related to an operation, for example, and can display the map for road guidance, for example, the communication unit 13. The map image can be generated and displayed by acquiring the image or information transmitted from the car navigation device 5 via the.

  The position acquisition unit 15 acquires the position of the touch operation on the touch panel 30 (or the display surface of the display panel 20) by the user based on the output of the touch panel 30. For example, when the touch panel 30 is a resistive film type, the touch panel 30 outputs a voltage corresponding to the touch operation position when the touch operation is performed, so the position acquisition unit 15 determines the touch operation position by examining the output voltage of the touch panel 30. Can be acquired. The position acquisition unit 15 notifies the control unit 11 of information related to the acquired position.

  Based on the information given from the position acquisition unit 15, the control unit 11 determines which of the operation images displayed on the display panel 20 has been touched, that is, the plurality of images displayed on the display panel 20. One operation image to be operated is specified from the operation image. As a result, the control unit 11 can determine the content of the operation performed by the user, controls the drawing unit 14 to update the display on the display panel 20 according to the content of the operation, and operates via the communication unit 13. Send the contents to the target device.

  The controller device 1 according to the present invention detects a user operation on the touch panel 30, and the control unit 11 given information from the position acquisition unit 15 specifies one operation image to be operated. By enlarging and displaying the operation image, it has a function of notifying the user who has performed the operation that the contact operation has been accepted. FIG. 2 is a schematic diagram showing a display example of the display panel 20 by the operation device 1 according to the present invention. FIG. 3 is a schematic diagram for explaining an enlarged display of the operation image by the operation device 1 according to the present invention. FIG. 4 is a table summarizing information for explaining the enlarged size of the operation image.

  The controller device 1 displays, for example, three substantially square icons (operation images) 21 arranged in a horizontal line at a predetermined interval on the display panel 20 (see FIG. 2A). In this example, the three operation images 21 are assumed to have the same size in an initial state (a state in which no contact operation is performed by the user), but this is an example and the present invention is not limited to this. When the user performs a contact operation, the controller device 1 specifies one operation image 21 to be operated from the contact position of the touch panel 30 and displays the one operation image 21 in an enlarged manner than the other operation images 21 ( (Refer FIG.2 (b)). Accordingly, the user can visually recognize that the operation image 21 that has been subjected to the contact operation is enlarged and can confirm that the contact operation has been correctly received by the controller device 1. The enlarged display of the operation image 21 is preferably performed within a time of about 50 ms after detecting a contact operation by the user.

  For example, assume that the display size of the operation image 21 in the initial state is a square of 10 mm × 10 mm. At this time, the operation device 1 according to the present invention allows the operation image 21 to be displayed so that one operation image 21 that is a target of the contact operation has a display size larger than at least a circle having a diameter of 18 mm (shown by a broken line in FIG. 3). An enlarged display is performed.

  The average thickness of the index finger of the adult female (second finger distal joint width) is about 15 mm to 17 mm, and the average thickness of the index finger of the adult male is about 17 mm to 18 mm (see FIG. 4, Reference). Reference: “Japanese anthropometric data”, published by the Research Center for Human Life Engineering). When the user touches the touch panel 30 with his / her finger, the user's finger covers a part of the display panel 20, so that the user cannot visually recognize one operation image 21 to be operated. Therefore, by displaying one operation image larger than a circle having a diameter of at least 18 mm, even when an adult male user performs a contact operation, at least a portion of the operation image 21 is covered by the user's finger. The user can visually recognize the enlarged operation image 21.

  FIG. 5 is a flowchart showing a procedure of an operation reception process performed by the controller device 1 according to the present invention, which is a process performed by the control unit 11 of the controller device 1. First, the control unit 11 checks whether or not the touch operation by the user has been detected by the touch panel 30 based on the presence / absence of a notification from the position acquisition unit 15 (step S1), and if the contact operation has not been detected (S1: NO), and waits until a contact operation is detected. When the contact operation is detected (S1: YES), the control unit 11 acquires the contact operation position by the position acquisition unit 15 (step S2), and operates from the plurality of operation images 21 displayed on the display panel 20. One operation image 21 is specified (step S3).

  Next, the control unit 11 enlarges and displays the specified one operation image 21 on the display panel 20 by the drawing unit 14 (step S4), and displays the user operation contents in the car navigation device 5, the audio device 6, and the air conditioner device. 7 is notified to the other devices via the communication unit 13 (step S5), and the process is terminated.

  In the operation device 1 having the above configuration, one operation image 21 to be operated is specified based on the contact operation position on the touch panel 30 among the plurality of operation images 21 displayed on the display panel 20, and the specified one is specified. By performing the enlarged display so that the operation image 21 is larger than the other operation images 21, the user can enlarge which operation image 21 has been received by the operation device 1. Can be easily recognized.

  In the present embodiment, when the operation image 21 is enlarged and displayed, the operation image 21 is enlarged so as to be larger than a circle having a diameter of 18 mm. However, the present invention is not limited to this. In a case where the operation image 21 is displayed with a size of 18 mm or more in the initial state, it is necessary to display one operation image 21 to be operated in a larger size. In such a case, it is preferable to enlarge and display the operation image 21 at least about 1.2 to 1.5 times the display size of the operation image 21 in the initial state. Further, as long as the operation device 1 can acquire the contact area of the user's finger with respect to the touch panel 30, for example, the operation image 21 may be enlarged to be twice or more of the acquired contact area.

  Moreover, although the operating device 1 which concerns on this Embodiment shall be mounted in a vehicle, it is not restricted to this, You may apply the structure of this invention to operating devices other than vehicle mounting. The operation device 1 is configured to receive operations on devices such as the car navigation device 5, the audio device 6, and the air conditioner device 7, but the operation target device is an example and is not limited thereto. Further, the arrangement, shape, and the like of the operation image 21 shown in FIGS. 2 and 3 are examples and are not limited thereto.

Moreover, the display and the enlarged display of the operation image 21 on the display panel 20 by the operation device 1 can be performed by various other methods as shown in the following modified examples.
(Modification 1)
FIG. 6 is a schematic diagram for explaining an enlarged display of the operation image 21 by the operation device 1 according to the first modification. The controller device 1 according to the modified example 1 performs enlarged display so that the operation image 21 to be operated related to the user's contact operation gradually increases. This can be realized, for example, by displaying a plurality of operation images 21 of different sizes in order from the smallest to the largest, giving the user a visual effect that gradually enlarges one operation image by animation display. Therefore, it is possible to make it easier for the user to visually recognize one operation image 21 to be operated.

(Modification 2)
FIG. 7 is a schematic diagram illustrating an example of the operation image 21 displayed by the operation device 1 according to the second modification. The controller device 1 according to the modified example 2 displays a spherical image (or an image with a bright circle at the center) on the display panel 20 as an operation image 21 in an initial state in which no user contact operation is performed, As one operation image 21 specified as an operation target, an image of a sphere with a recessed center (or an image with a dark circle at the center) is displayed. Thereby, a spherical button is crushed with a finger, the central part is recessed, and a visual effect can be given to the user that is spread outward, and one operation image accepted as an operation target of a contact operation 21 can be more easily recognized by the user.

(Modification 3)
FIG. 8 is a schematic diagram illustrating a display example of the display panel 20 by the operation device 1 according to the third modification. In order to display many operation images 21 on the display panel 20, the operation device 1 according to the modification 3 displays a plurality of operation images 21 in a line in close proximity (see FIG. 8A). When the operation image 21 is displayed in close proximity, when one operation image 21 to be operated is enlarged and displayed, a part or all of the enlarged one operation image 21 and another adjacent operation image 21 are overlapped. In such a case, the controller device 1 enlarges and displays one operation image 21 to be operated with priority over the other operation images 21 (see FIG. 8B). That is, the controller device 1 displays an enlarged operation image of the position on another operation image 21 and displays the enlarged image. As a result, even when the operation images 21 overlap, the user can easily view one operation image 21 of the operation target, and the user recognizes the one operation image 21 received as the operation target more. Can be made easier.

(Modification 4)
FIG. 9 is a schematic diagram for explaining an enlarged display of the operation image 21 by the operation device 1 according to the fourth modification. For example, when the display panel 20 is a liquid crystal panel or the like, there is a possibility that the display surface of the display panel 20 is pressed by the user's contact operation, and the display panel 20 is distorted and the display color changes at the finger contact portion and the surrounding portions. There is. Therefore, the controller device 1 according to the modified example 4 is gradually concentrically outwardly centered on the contact operation position (indicated by “x” in FIG. 9) on the touch panel 30 by the position acquisition unit 15. The operation image 21 whose color or brightness changes is enlarged and displayed. By magnifying and displaying the operation image 21 whose color or brightness has been changed in advance, it is possible to suppress a reduction in the visibility of the operation image 21 due to a change in display color caused by distortion of the display panel 20 due to a touch operation.

(Modification 5)
FIG. 10 is a block diagram illustrating a configuration of the controller device 1 according to the fifth modification. The controller device 1 according to the modification 5 includes a vibration generating unit 40 that applies vibration to the display panel 20 on the back surface (the surface opposite to the display surface) of the display panel 20. The vibration generating unit 40 includes, for example, a motor and a weight having an asymmetric shape fixed to the rotation shaft of the motor, and the weight is rotated by the motor to periodically collide the weight with the back surface of the display panel 20. It can be set as the structure which generate | occur | produces a vibration. The operation of the vibration generating unit 40 is controlled by the control unit 11, and the control unit 11 operates the vibration generating unit 40 to vibrate the display panel 20 when detecting a user's contact operation on the touch panel 30. . Thereby, since the finger of the user who performed the contact operation can feel the vibration, the user can easily and reliably recognize that the contact operation has been received by the operation device 1.
