Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen operation device applied to various devices such as a car navigation device of a vehicle and an audio device for performing various operations while confirming the screen of monitor means.

[0002]

2. Description of the Related Art In recent vehicles, there is a type in which a monitor television (monitor means) having a monitor screen is attached to an instrument panel of the vehicle or a storage portion formed in the instrument panel. The map screen of the car navigation device is displayed on the monitor screen.

Further, in addition to the above-mentioned car navigation device, various devices such as an audio device and an air conditioner are mounted on the vehicle, so that, for example, each device is constituted by an icon or the like. Display the virtual control panel on the monitor TV screen, switch the screen display of the monitor TV to the virtual control panel corresponding to the desired device with the controller, and use the controller to display the pointer etc. displayed on the screen of the monitor TV. There is also a configuration in which the desired control content or operation content is executed by moving the icon or the like corresponding to the desired control content or operation content and selecting the icon or the like.

With such a structure, even if the number of types of devices mounted on the vehicle increases, there is an advantage that one controller can operate and control the various devices.

On the other hand, as a controller used in such an apparatus, there is a controller having a touch panel provided in the main body of the controller.

That is, by moving the finger or the like on the touch panel by making the coordinate position on the touch panel of the controller correspond to the coordinate position on the screen of the monitor television,
The pointer displayed on the screen of the monitor TV is moved.

By the way, when the above controller is operated while the vehicle is running, the finger may shake on the touch panel due to the vibration of the vehicle and the pointer may move on the screen of the monitor television. As a result, for example, the pointer is positioned on an unintended icon and this icon is in a selected state (for example, the color of the icon changes), or the pointer is frequently moved between multiple icons within a short time. Move to and multiple icons will be alternately selected in a short time.

In order to prevent such a problem, a gray zone is set between adjacent icons, and even if the pointer deviates from the icon, if the pointer is located within a predetermined range, A configuration in which the selected states of the above icons are not released is considered (for example, refer to Patent Document 1 below).

[0009]

[Patent Document 1] Japanese Patent Laid-Open No. 11-127399

[0010]

However, when the gray zone is set in this way, there occurs a phenomenon that the selected state is continued even though the finger position on the touch panel is largely separated from the selected icon. . Such a phenomenon causes an uncomfortable feeling that the operation feeling on the touch panel does not match the screen state of the monitor TV, and there is plenty of room for improvement from the viewpoint of operability.

In particular, when the vibration from the vehicle is extremely small, such as when the vehicle is stopped, since the shaking of the finger on the touch panel is small in the first place, the above-mentioned problems do not occur, and instead the above-mentioned problems occur. The feeling of strangeness increases.

It is an object of the present invention to obtain a screen operation device which has less discomfort during operation and has high operability.

[0013]

According to a first aspect of the present invention, there is provided a screen operation device, which is connected to the operation means for issuing an operation signal including position information according to a position on the screen of the monitor means by a predetermined operation. Then, a plurality of selection sections are displayed at predetermined positions on the screen, and the position information of the operation signal sent from the operation means in the display state of the plurality of selection sections corresponds to one of the plurality of selection sections. In the case where the selected state is set, a release area is set between the plurality of selection units at a position apart from each of the plurality of selection units on the screen, and the selection state is set. When the operation signal including the position information corresponding to the release area is received, or when the operation signal including the position information corresponding to the state of leaving the release area is received, And and control means for releasing the.

In the screen operating device having the above structure, the control means displays a plurality of selection sections on the screen of the monitor means.
When the operation means is operated in this state to send an operation signal to the control means, if the position information included in the operation signal corresponds to the position of any one of the selection units on the screen of the monitor means, the control means is applicable. The selection unit to be selected is set to the selected state.

By the way, when the plurality of selection sections are displayed on the screen of the monitor means, the release area is set on the screen of the monitor means by the control means. This release area is
It is set at a position apart from each selection unit on the screen of the monitor means and between any of the plurality of selection units and any other unit.

Here, an operation signal including position information corresponding to a position in the release area or an operation signal including position information corresponding to a state of leaving the release area in any one of the plurality of selection units being selected. Is sent from the operating means to the control means, the control means releases the selected state.

As a result, the position information largely separated from the selection unit in the selected state (that is, the position information in the release area).
Even though the operation signal including the is sent from the operation means to the control means, the operation in the operation means and the monitor means in which the selection unit at the position away from the position corresponding to the position information of the operation signal is still in the selected state It is possible to display a screen corresponding to the operation feeling without causing a feeling of inconsistency with the screen display, thus improving operability.

According to a second aspect of the present invention, there is provided a screen operating device, which is connected to the operating means for issuing an operation signal including position information corresponding to a position on the screen of the monitor means by a predetermined operation, and is connected to the monitor means to display the screen. Display multiple selection parts at predetermined positions,
When the position information of the operation signal sent from the operation means in the display state of the plurality of selection units corresponds to any one of the plurality of selection units, while bringing the selection unit into the selected state, The maintenance area is set in a predetermined range on the screen including any one of the plurality of selection units inside corresponding to each of the plurality of selection units, and the position information of the operation signal from the operation unit is set. Is in the maintenance area and corresponds to a position in the maintenance area excluding the selection unit, maintains the state of the screen in a state before receiving the operation signal, and further Control means for changing the setting range of the maintenance area based on conditions.

In the screen operation device having the above structure, the control means displays a plurality of selection sections on the screen of the monitor means.
When the operation means is operated in this state to send an operation signal to the control means, if the position information included in the operation signal corresponds to the position of any one of the selection units on the screen of the monitor means, the control means is applicable. The selection unit to be selected is set to the selected state.

By the way, when the plurality of selection units are displayed on the screen of the monitor means, the control means sets the plurality of maintenance areas on the screen of the monitor means. Each of these maintenance areas is set corresponding to each of the plurality of selection units, and further includes the corresponding selection unit inside (that is, the maintenance area is set around the corresponding selection unit). Be done).

When the control means receives an operation signal having position information corresponding to the position inside the maintenance area excluding the corresponding selection part, the control means changes the display state of the screen of the monitor means to this operation signal. Maintained in the condition it was in before it was received.

As a result, immediately after the operating means is operated to select any one of the selection sections, an operation signal including position information of a position out of the selection section is emitted due to fluctuations in the operation or shaking. However, the selection state of the selection unit does not change. Therefore, careful and strict operation is not required for the operation of the operation means, and the operability is improved.

Here, in this screen operation device, the size of the maintenance area is changed based on a predetermined condition.

Therefore, for example, when the operation area of the operating means is less likely to fluctuate or shake, the maintenance area is narrowed to make the display state of the screen on the monitor means sensitive to the operation of the operating means (ie, selection). It is possible to select, cancel, and switch parts, and to quickly respond (react) the screen display of the monitor means to the operational feeling when operating the operation means. This improves operability.

In addition, for example, when the surrounding environment when operating the operating means is a relatively swayable place (for example, the interior of a running vehicle), the swayable environment can be increased by increasing the maintenance area. In this case, it is possible to prevent the selection state of the selection unit from being canceled due to careless operation of the operation means, and in this sense, the operability is improved.

A screen operating device according to a third aspect is the first aspect.
Alternatively, in the present invention according to claim 2, the control means is activated when the control signal receives the operation signal including the position information corresponding to a position separated by a predetermined range from the selection section on the screen, and a predetermined arrival signal. It is characterized in that it is provided with an arrival signal transmitting means for transmitting.

In the screen operation device having the above-mentioned configuration, the operation means is operated, and the position information of the operation signal received by the control means from the operation means at this time is at a position separated by a predetermined range from the selection section on the screen of the monitor means. In the case of the corresponding position information, the arrival signal transmitting means is activated to emit a predetermined arrival signal that can be recognized by any of the five senses of a person, such as light, sound, and vibration. As a result, it is possible to grasp the operation result of the operation unit without staring at the screen of the monitor unit.

In this screen operating device, the arrival signal transmitting means emits a predetermined arrival signal. However, as described above, if the arrival signal is a signal that can be recognized by one of the five senses of a person, It is not limited to light, sound, vibration (pressure) and the like. When the arrival signal is light, the monitor means may also serve as the arrival signal transmission means. Further, when the arrival signal is vibration, pressure, or the like, if the body (for example, palm or finger) is basically always in contact with the operation means when the operation means is operated, the arrival signal is transmitted to the operation means. Means may be provided.

A screen operating device according to a fourth aspect is the third aspect.
In the present invention described, the arrival signal transmission means gradually or stepwise changes the arrival signal as the position on the screen corresponding to the position information approaches the selection unit. .

In the screen operating device having the above structure, the arrival signal changes gradually or stepwise as the position on the screen of the monitor means corresponding to the position information of the operation signal approaches the selection unit.

Here, for example, in the case of a simple arrival signal that does not change, it can be understood that the operation unit has issued an operation signal including position information corresponding to a position within a predetermined range from the selection unit. However, it is not possible to grasp whether this position information is in the very vicinity of the selection unit or in the vicinity of the peripheral portion of the predetermined range. Therefore, after the arrival signal is transmitted, it is not possible to grasp how much the operating means should be operated to select the selection unit.

However, in the present screen operation device, the change in the arrival signal enables the degree of deviation between the position of the selection unit and the position on the screen of the monitor means corresponding to the position information included in the operation signal to be grasped, and the change in the arrival signal. By using as a guide, it is possible to select the selection unit without staring at the screen of the monitor means, and the operability is improved.

According to a fifth aspect of the present invention, there is provided a screen operating device, which is connected to the operating means for issuing an operation signal including position information corresponding to a position on the screen of the monitor means by a predetermined operation, and is connected to the monitor means to display the screen. An area that displays a plurality of selection units at predetermined positions, and the position information of the operation signal sent from the operation unit in the display state of the plurality of selection units includes the selection unit and corresponds to the selection unit. Control means for bringing the selection unit into a selected state when it corresponds to the above, further, the control means is a position separated from each of the plurality of selection units on the screen and the plurality of selections. When a release area and a maintenance area are set between the parts, and a transition is made from the release area corresponding to the first selection unit to the maintenance area corresponding to the second selection unit, and the first selection unit is supported. To maintain When receiving the operation signal including the position information in the case of at least one of the case where the transition to the corresponding release area to the second selecting portion from the inner, first
It is characterized in that the selection state of the selection unit is changed to a non-selection state.

In the screen operation device having the above structure, the control means displays a plurality of selection sections on the screen of the monitor means.
When the operation means is operated in this state to send the operation signal to the control means, the control means causes the position information included in the operation signal to correspond to any selection section on the screen of the monitor section and an area corresponding to this selection section. If so, the corresponding selection unit is set to the selected state.

By the way, when the plurality of selection sections are displayed on the screen of the monitor means, the release area and the maintenance area are set on the screen of the monitor means by the control means. The release area is set at a position apart from each selection unit on the screen of the monitor unit, and between any one of the plurality of selection units and any other unit.

Here, of the plurality of selection units, from the release area corresponding to the first selection unit in the selected state,
When a transition is made within the maintenance area corresponding to another second selection unit, and from within the maintenance area corresponding to the first selection unit in the selected state, a release area corresponding to another second selection unit When the control means receives the operation signal including the position information in at least one of the cases where it is moved inward, the first selection part which has been in the selected state until then is brought into the non-selected state by the control means.

As a result, even though the operation signal including the position information largely separated from the selection unit in the selected state is sent from the operation unit to the control unit, the position of the position separated from the position corresponding to the position information of the operation signal is detected. It is possible to display a screen corresponding to the operation feeling without causing a feeling of inconsistency between the operation of the operation means and the screen display of the monitor means that the selection unit is still in the selected state, thus improving the operability.

Further, as shown in FIG. 1, each of the line electrodes 48 has a scan circuit 54 provided in the controller 16.
Is connected to the power source 58 via. Scan circuit 54
Is connected to the CPU 18 of the computer 24, and C
Under the control of the PU 18, the respective line electrodes 48 are electrically connected to the power source 58 in a preset order.

On the other hand, the line electrode 50 is connected to the control unit 1
It is grounded through a scan circuit 56 provided in the No. 6. The scan circuit 56 is also the computer 2 described above.
4 is connected to the CPU 18, and under the control of the CPU 18, it is detected whether or not a current is flowing through each line electrode 50 in a preset order, and the detection result is fed back to the CPU 18 as an operation signal.

Here, the horizontal direction (X2 direction) and the vertical direction (Y2 direction) of the back surface of the sheet 46 of the touch panel 42 (that is, the surface exposed from the hole 40 of the case 38).
Respectively correspond to the horizontal direction (X1 direction) and the vertical direction (Y1 direction) on the screen 14 of the monitor television 12 described above. In the computer 24, each of the line electrode 48 and the line electrode 50 on the touch panel 42. The position on the screen 14 corresponding to the intersection (hereinafter, this position is referred to as "virtual intersection" for convenience) is determined.

<Operations and Effects of the Present Embodiment> In the present center control device 10, the CPU 18 reads the navigation program, the map screen data, etc. from the ROM 22 and executes and processes them to display the screen of the monitor television 12. At 14, for example, a map around the current location is displayed.

Further, for example, when the CPU 18 reads a menu program for selecting various functions of the center control device 10 from the ROM 22 or the like,
As shown in FIG. 6, a plurality of selection buttons 26 representing various function names and their contents by characters or pictures are arranged in a matrix on the screen 1.
4, and the CPU 18 stores the selection processing program whose outline is shown in the flowchart of FIG.
Read from 22 etc.

When the selection processing program is read and executed in step 100, various initial settings are made in step 102, and further, in step 104, the second selection area 30 for each selection button 26, A gray zone 32 and a cancel zone 34 are set.

Next, in step 106, the scan circuit 5
4 is operated so that each line electrode 48 supplies the power 5 in a predetermined order.
8, the scan circuit 56 is operated and the conduction state of each line electrode 50 is detected in a predetermined order,
An operation signal including the information on the conduction state is sent to the CPU 18.

In this way, the scan circuit 54 connects the respective line electrodes 48 to the power supply 58 in a predetermined order, and the scan circuit 56 detects whether or not a current has flown in each line electrode 50 in a predetermined order. , The conduction state between each line electrode 48 and each line electrode 50 at the intersection of each line electrode 48 and each line electrode 50, that is, the X2 direction and the Y direction.
A sheet 46 (touch panel 4) extending in both directions in two directions
In which part of 2) the pressing force acts (the coordinate position of the pressing force acting portion on the sheet 46) is detected.

In this state, the vehicle occupant controls the controller 36.
When the back surface of the sheet 46 (touch panel 42) is touched with a finger 62 and the sheet 46 is pressed toward the sheet 44 with an appropriate force, the pressed portion of the sheet 46 bends toward the sheet 44 (see FIG. 6). As a result, the line electrode 50 is brought into contact with the opposing line electrode 48 at the pressing portion of the sheet 46 and becomes conductive, and this conduction is detected by the scan circuits 54 and 56.

An operation signal from the scan circuit 56 is sent to the CPU 1
8 is fed back, the operation signal fed back in step 108 is processed, and the coordinate position of the pressing force acting portion on the seat 46 is determined based on the operation signal. Further, based on this determination result, the sheet 4
6 is the coordinate position of the pressing force acting portion (see, for example, FIG.
A virtual intersection on the screen 14 corresponding to the position of the P portion indicated by the triangle in FIG.

Next, at step 110, it is judged if the fed back operation signal includes information on the virtual intersection, that is, if at least one set of the line electrodes 48, 50 is conductive. It When it is determined in step 110 that the operation signal includes the information of the virtual intersection, that is, it is determined that at least one of the line electrodes 48 and 50 is in the conductive state, step 112.
In which of the first selection areas 28 the virtual intersection included in the operation signal is included is determined.

Next, in step 114, the history of the virtual intersection included in the operation signal received immediately before this operation signal is read from the RAM 20 or the like, and when it is determined in step 116 that there is no history, it is shown in FIG. As shown in FIG. 7 (see the selection button 26 in the upper right of FIG. 7), the first
The color of the selection button 26 displayed in the selection area 28 is reversed, and the function or operation represented by the selection button 26 is selected. In this state, for example, the function or operation represented by the selection button 26 selected by operating the enter button or the like provided on the controller 36 or the like is executed.

Next, in step 120, the information of the virtual intersection included in this operation signal is stored as a history in the RAM 20 or the like, and the process returns to step 100 via step 122.

On the other hand, if neither of the line electrodes 48, 50 is conducting, that is, if the touch panel 42 is not pressed, it is determined in step 110 that there is no virtual intersection, and in step 124 the RAM 20 is up to that point. The history of virtual intersections stored in etc. is deleted. Therefore, immediately after this selection processing program is executed, or when the finger 62 is once released from the touch panel 42 and then the touch panel 42 is pressed again, there is no history of virtual intersections in the RAM 20 or the like. Therefore, basically, the function or the like corresponding to the selection button 26 in the first selection area 28 including the virtual intersection is selected, and the selection button 26 is selected.
Is reversed.

If it is determined in step 116 that the history of the previous virtual intersection exists in the state where the operation signal is fed back, the position of the virtual intersection included in the received operation signal is within the second selection area 30. It is determined in step 130 whether or not the vehicle is located at. When it is determined in step 130 that the position of the virtual intersection included in the received operation signal is located in the second selection area 30, the color of the selection button 26 in the second selection area 30 including the virtual intersection is reversed. In step 132, it is determined whether or not (that is, whether or not the function or operation corresponding to the selection button 26 is in the selected state).

As a result, if the color of the selection button 26 has not been inverted, in step 118 the inversion processing of the selection button 26 and the selection processing of the function or operation corresponding to this selection button 26 are performed. If it is determined in step 132 that the corresponding selection button 26 has already been highlighted and the function or operation corresponding to the selection button 26 has been selected, the process proceeds to step 120.

On the other hand, if the position of the virtual intersection included in the received operation signal is not within the second selection area 30, step 1
When it is determined in step 30, it is determined in step 134 whether the position of the virtual intersection included in the received operation signal is located within the gray zone 32. When it is determined in step 134 that the position of the virtual intersection is not in the gray zone 32, the process proceeds to step 120.

In this state, since there is a history of virtual intersections before that, basically the color of any one of the selection buttons 26 is reversed and the function or operation corresponding to this selection button 26 is selected. It is in the state of being However, by proceeding directly from step 134 to step 120, the inverted state of the selection button 26 and the selection button 2
The selected states of functions and operations corresponding to 6 are maintained.

On the other hand, if it is determined in step 134 that the position of the virtual intersection is within the gray zone 32, the process proceeds to step 136. In step 136, it is judged from the history of the virtual intersection just before read in step 114 whether or not the virtual intersection just before was located in the cancel zone 34. If it is determined that the previous virtual intersection is not located in the cancellation zone 34, step 120
Go to. Therefore, even in this case, the inverted state of the selection button 26 and the selection state of the function or operation corresponding to the selection button 26 are maintained.

On the other hand, when it is determined in step 136 that the previous virtual intersection is located in the cancel zone 34, in step 138, the history when the virtual intersection is located in the gray zone 32 is read from the RAM 20 or the like. And
Of the history of virtual intersections located in the gray zone 32 in step 140, in the history that is closest in time (immediately before), the gray zone 32 in which the virtual intersection is located,
It is determined whether or not the gray zone 32 in which the current virtual intersection is located is in the same first selection area 28.

If it is determined in step 140 that the gray zone 32 located most recently is the same as the gray zone 32 in which the current virtual intersection is located, step 12
Go to 0. That is, in this state, the movement locus of the virtual intersection corresponding to the position of the finger 62 on the touch panel 42 passes through the cancel zone 34, but basically returns to the original gray zone 32. Therefore, in this case, the inverted state of the selection button 26 and the selection state of the function or operation corresponding to the selection button 26 are maintained.

On the other hand, if it is determined in step 140 that the gray zone 32 in which the current virtual intersection is located is different from the gray zone 32 in which it was located in the latest, the process proceeds to step 142. In step 142, the selection button 26 whose color has been inverted until then is restored to the original color, and the selection state of the function or operation corresponding to this selection button 26 is canceled.

As described above, in the present embodiment,
Basically, even if the virtual intersection is separated from the selection button 26 or the second selection area 30 around it by moving the finger 62 on the touch panel 42, if the virtual intersection is located in the gray zone 32, the selection button The selected state including the color inversion of 26 is not released. Therefore, even if the finger 62 vibrates or shakes on the touch panel 42 due to vibration of the vehicle or the like, the selected state is inadvertently released, or the color of another adjacent selection button 26 is reversed. (That is, the function or operation corresponding to another adjacent selection button 26 is not selected).

As described above, in the present embodiment, when operating the controller 36, it is not necessary to pay close attention to the slight shaking and vibration of the finger 62 on the touch panel 42, and the operability is extremely high.

On the other hand, when the finger 62 moves on the touch panel 42, the virtual intersection moves from the gray zone 32 to the cancellation zone 34, and further, the first selection area 28 different from the first selection area 28 including the previous gray zone 32. When it moves to the gray zone 32 in the 1 selection area 28, the selection state of the selection button 26 and the function or operation corresponding to this selection button 26 is canceled. That is, when the position of the virtual intersection (in other words, the position of the finger 62 on the touch panel 42) is already largely separated from the selection button 26 in the selected state due to the movement of the virtual intersection along the movement trajectory as described above, The selection state of the selection button 26 and the function or operation corresponding to the selection button 26 is released.

Therefore, the finger 62 on the touch panel 42 is
It is possible to reduce or eliminate the sensory (operational feeling) difference between the position of and the position of the selection button 26 in the selected state, and in this sense, the operability is improved.

In the present embodiment, the gray zone 32 is set around the second selection area 30 as described above, but the setting method and setting conditions of the gray zone 32 are not particularly limited. Absent. Therefore, for example, the range of the gray zone 32 may be set in advance for each menu screen, or automatically based on the position of the selection button 26 displayed on the screen 14, the interval between the adjacent selection buttons 26, and the like. Alternatively, the gray zone 32 may be set.

<Second Embodiment> Next, another embodiment of the present invention will be described. In describing each of the following embodiments, the same parts as those of the above-described embodiments are substantially the same as those of the above-described embodiments including the first embodiment. A reference numeral is given and its description is omitted.

Further, in describing the selection processing program in each of the following embodiments, the above-described embodiment including the selection processing program applied in the first embodiment will be described. With respect to the step performing substantially the same process as the step number given in the flowchart of the selection processing program applied in the above form, the same step number is given and the description thereof will be omitted.

FIG. 9 shows a center control device 1 to which the screen operation device according to the second embodiment of the present invention is applied.
A schematic of the configuration of 60 is shown. As shown in this figure, the basic configuration is the same as that of the center control device 10 according to the first embodiment, but the control unit 16
The processing in 2 is different from that of the control unit 16 of the center control device 10 in the first embodiment.

That is, as shown in the schematic flow chart of the selection processing program in the present embodiment of FIG. 10, in the present embodiment, the selection processing program is executed in step 180 and various initials are executed in step 102. When the setting is performed, in step 106, the scan circuit 54 is activated to connect the line electrodes 48 to the power supply 58 in a predetermined order, and the scan circuit 56 is activated to electrically connect the line electrodes 50 in a predetermined order. The state is detected, and the operation signal including the information on the conduction state is sent to the CPU 18.

Next, in step 182, the operation signal is basically processed in the same manner as in step 108 (see FIG. 8), but in step 184, the finger 62 on the touch panel 42 is operated based on the processing result of this operation signal. The pressing range is determined.

That is, when the finger 62 is raised and touches the touch panel 42 as shown in FIG.
As shown in (A), the pressing range of the finger 62 has a small difference (ratio) between the width dimension of the finger 62 and the longitudinal direction (direction from the base of the finger 62 to the fingertip), and in contrast to this, FIG.
Lay down your finger 62 as shown in (B) (ie,
When the touch panel 42 is touched (with the belly portion of the finger 62), the longitudinal dimension of the finger 62 becomes larger than the width dimension of the finger 62, as shown in FIG.

Therefore, the number of conductive portions with the line electrodes 48 and 50 along the X2 direction and the number of conductive portions with the line electrode 48 along the Y2 direction are detected (step 182) to detect the touch panel 42. The posture of the finger 62 above is determined (step 184).

Then, in step 186, step 1
The second selection area 30, the gray zone 32, and the cancel zone 34 are set for each selection button 26 based on the detection results and the determination results in 82 and 184.

Here, in the present embodiment, step 18
From the detection result and the determination result in 2, 184, the number of conductive portions of the line electrodes 48, 50 along the X2 direction and Y
When the difference between the number of conductive portions with the line electrodes 48 and 50 along the two directions is small, as shown in FIG.
The width of the gray zone 32 and the cancel zone 34 along the X1 direction on the screen 14 is widened, and the range of the second selection area 30 along the X1 direction is narrowed by the increase in the width of the gray zone 32 and the cancel zone 34. . Further, the widths of the gray zone 32 and the cancel zone 34 along the Y1 direction on the screen 14 are narrowed, and the range of the second selection area 30 along the Y1 direction is reduced by the width reduction of the gray zone 32 and the cancel zone 34. (That is, the range of the first selection area 28 does not change).

By the way, the direction of shaking of the finger 62 on the touch panel 42 varies depending on the posture of the finger 62.
The shake in the 2) direction is large, but the shake in the vertical direction (Y2) tends to be small. On the other hand, when the finger 62 is laid down, the shaking in the vertical direction (Y2) is large,
The swing in the lateral direction (X2) tends to be small. Here, as described above, the line electrode 4 along the X2 direction is used.
When the difference between the number of conducting portions of 8 and 50 and the number of conducting portions of the line electrodes 48 and 50 along the Y2 direction is small, the widths of the gray zone 32 and the cancel zone 34 along the X1 direction are small. The area of the second selection area 30 along the X1 direction is narrowed by the expansion.

Therefore, in this case, even if the finger 62 in the X2 direction from the side of the selection button 26 in which the color is reversed (that is, the selection processing has been performed) sways comparatively greatly, the gray set wider than usual is set. Second, including adjacent selection buttons 26 across the zones 32 and cancel zones 34
As long as the finger 62 does not move to the selection area 30, the selected state up to that point will not be canceled or changed.

Therefore, even if the finger 62 is swayed in the X1 direction relatively greatly due to the vibration of the vehicle because the touch panel 42 is pressed while the finger 62 is standing, the unintentional release or change of the selected state is accompanied by this. It is possible to prevent the color of the selection button 26 from being changed, and in this sense, the operability is improved.

On the other hand, in this case, the widths of the gray zone 32 and the cancel zone 34 along the Y1 direction are narrowed, and the second selection area 3 along the Y1 direction is reduced by this decrease.
The range of 0 becomes wide.

Therefore, in this case, the gray zone 32 and the cancel zone 34 are relatively easily moved by shaking the finger 62 in the Y2 direction from the side of the selection button 26 whose color has been inverted (that is, the selection processing has been performed). Finger 6 to the second selection area 30 that includes the selection buttons 26 that are adjacent to each other across
2 moves, and the selected state up to that point is canceled or changed.

However, as described above, when the finger 62 is raised and the touch panel 42 is pressed, the shaking of the finger 62 in the Y2 direction becomes small. Therefore, unless the finger 62 is intentionally moved in the Y2 direction, that is, unless it is intended to select another selection button 26, the second selection area 30 including the adjacent selection buttons 26 is easily included.
The finger 62 is not moved to.

Further, as described above, the finger 6 in the Y2 direction when the touch panel 42 is pressed while the finger 62 is upright.
Since the swing of 2 is small, the relatively large movement of the finger 62 in the Y2 direction is often intentional. Here, the gray zone 3 along the Y1 direction in this case
2 and the cancellation zone 34 are narrow, and the range of the second selection area 30 is widened accordingly. Therefore, the selected state is immediately canceled or changed even by moving the relatively small finger 62 in the Y2 direction. That is, the screen 1 when the finger 62 is intentionally moved while the finger 62 is basically upright
The response of No. 4 is fast, and the operability and the state of the screen 14 quickly coincide with each other, so that the operability becomes extremely high.

On the other hand, as described above, when the number of conductive portions with the line electrodes 48 and 50 along the Y2 direction is relatively large with respect to the number of conductive portions with the line electrodes 48 and 50 along the X2 direction ( That is, when the finger 62 is laid down and the touch panel 42 is pressed), as shown in FIG. 12, the widths of the gray zone 32 and the cancellation zone 34 along the Y1 direction widen, and the increase along the Y1 direction corresponds to this increase. Further, the range of the second selection area 30 becomes narrow.

Therefore, in this case, even if the finger 62 in the Y2 direction from the side of the selection button 26 in which the color is reversed (that is, the selection processing has been performed) sways comparatively greatly, the gray set wider than usual is set. Second, including adjacent selection buttons 26 across the zones 32 and cancel zones 34
As long as the finger 62 does not move to the selection area 30, the selected state up to that point will not be canceled or changed.

Therefore, even if the finger 62 is relatively swayed in the Y1 direction due to the vibration of the vehicle because the touch panel 42 is pressed with the finger 62 lying down, the unintentional release or change of the selected state is accompanied by this. It is possible to prevent the color of the selection button 26 from being changed, and in this sense, the operability is improved.

On the other hand, in this case, the widths of the gray zone 32 and the cancel zone 34 along the X1 direction are narrowed, and the second selection area 3 along the X1 direction is reduced by this reduction.
The range of 0 becomes wide.

Therefore, in this case, the gray zone 32 and the cancel zone 34 are relatively easily moved by shaking the finger 62 in the X2 direction from the side of the selection button 26 whose color has been reversed (that is, the selection processing has been performed). Finger 6 to the second selection area 30 that includes the selection buttons 26 that are adjacent to each other across
2 moves, and the selected state up to that point is canceled or changed.

However, as described above, when the finger 62 is laid down and the touch panel 42 is pressed, the shaking of the finger 62 in the X2 direction becomes small. Therefore, unless the finger 62 is intentionally moved in the X2 direction, that is, unless it is intended to select another selection button 26, the second selection area 3 including the adjacent selection buttons 26 is easily included.
The finger 62 is never moved to 0.

Since the finger 62 swings in the X2 direction when the touch panel 42 is pressed with the finger 62 lying down, the relatively large movement of the finger 62 in the X2 direction is as follows. Often intentional.

Here, in this case, the widths of the gray zone 32 and the cancel zone 34 along the X1 direction are narrow, and the range of the second selection area 30 is widened accordingly, so that a relatively small finger in the X2 direction. The movement of 62 also immediately cancels or changes the selected state. That is, finger 6
Basically, the reaction of the screen 14 when the finger 62 is intentionally moved in a state where the person 2 is laid down is fast, and the operability and the state of the screen 14 quickly coincide with each other, so that the operability becomes extremely high.

As described above, in the present embodiment, the second selection area 30, the gray zone 32, and the cancel zone 3 are appropriately selected according to the posture of the finger 62 on the touch panel 42.
Since the range of 4 is set, it is possible to reduce or prevent inadvertent release or change of the selected state due to shaking or the like, and moreover, for the movement of the finger 62 for the purpose of releasing or changing the selected state, the selected state is quickly switched The state of the screen 14 can be made to correspond to each other, and the operability is extremely high.

<Third Embodiment> Next, the third embodiment of the present invention will be described.
The embodiment will be described.

FIG. 13 shows an outline of the configuration of the center control device 210 to which the screen operation device according to this embodiment is applied. As shown in this figure, the basic configuration is the same as that of the center control device 10 according to the first embodiment, but the processing in the control unit 212 is the same as that of the center control device 10 according to the first embodiment. The control unit 16 of FIG. Further, in the center control device 10, the computer 2 of the control unit 212 is used.
A suspension control computer 214 is connected to the CPU 18 constituting the CPU 4.

The suspension control computer 214 basically constitutes an electronically controlled suspension device of the vehicle, and various kinds of sensors such as a speed sensor, an acceleration sensor, a steering angle sensor, and a vehicle height sensor provided at appropriate positions of the vehicle are provided. For example, the vibration state of the vehicle is determined based on the signal from the sensor, and the shock absorber is adjusted according to the vibration state (above, those not shown are not shown).

Here, in the present embodiment, the suspension control computer 214 sends a vibration signal corresponding to the vibration state of the vehicle to the CPU 18 of the computer 24. In the ROM 22 and the like of the computer 24, the second selection area 3 having a different range (width) according to the vibration signal is provided.
The patterns of 0, gray zone 32, and cancel zone 34 are stored.

That is, as shown in the flow chart of FIG. 14, in this embodiment, when the selection processing program is executed in step 230 and various initial settings are made in step 102, the suspension control computer 214 is executed in step 232. The vibration signal from is read.

Next, in step 234, the vibration signal is processed to determine the current vibration state of the vehicle. further,
In step 236, the patterns of the second selection area 30, the gray zone 32, and the cancellation zone 34, which are preset and stored in the ROM 22 or the like, are read, and the patterns are set within the range set in the pattern suitable for the determined vibration state. The 2 selection area 30, the gray zone 32, and the cancel zone 34 are set on the screen 14 at step 238.

Here, in the present embodiment, the second selection area 30, the gray zone 32, and the cancel zone 3 are used.
In the pattern No. 4, the larger the vibration, the second selection area 30
Is narrower, and accordingly, the gray zone 32 and the cancel zone 34 are wider. Therefore, even if the finger 62 shakes greatly on the touch panel 42 due to the large vibration of the vehicle,
The finger 62 must move across the relatively wide gray zone 32 and the cancel zone 34 to a position corresponding to the second selection area 30 including other selection buttons 26 adjacent to the selection button 26 in the selected state. For example, the selection status will not be changed or canceled.

On the other hand, when the vibration of the vehicle is relatively small, such as when the vehicle is stopped, the second selection area 30 is wide, and accordingly the gray zone 32 and the cancel zone 34 are narrow. The selection state is easily changed or canceled by moving the finger 62 on the touch panel 42.

That is, in this state, since the finger 62 rarely shakes carelessly, the finger 6 on the touch panel 42
The movement of 2 is basically an intentional movement for the purpose of changing or canceling the selection state. Here, in this state, as described above, the selection state is easily changed or canceled by the movement of the finger 62 on the touch panel 42, and the screen 14 reacts quickly.

As described above, in the present embodiment, when the finger 62 is easily shaken, it is possible to effectively prevent the release or change of the selected state due to the shake of the finger 62, and the finger 62 is hard to shake. In the state, since the screen 14 and the like can be quickly reacted to the movement of the finger 62, the operability is extremely high.

<Fourth Embodiment> Next, a fourth embodiment of the present invention will be described.
The embodiment will be described.

FIG. 15 shows the outline of the configuration of the center control device 250 to which the screen operation device according to this embodiment is applied. As shown in this figure, the basic configuration is the same as that of the center control device 10 according to the first embodiment, but the processing in the control unit 252 is the same as that of the center control device 10 according to the first embodiment. The control unit 16 of FIG.

That is, in this embodiment, the selection processing is basically performed by the same selection processing program as the selection processing program described in the first embodiment. However,
In the present embodiment, the selection button 26 as the arrival signal displayed on the monitor television 12 as the arrival signal transmitting means.
The change of the color (that is, the wavelength of light) is not only the inversion and restoration, but also the change of the intermediate color.

As shown in the flow chart of FIG. 16, in the present embodiment, after the selection processing program is executed in step 260, the same processing as in the first embodiment is performed, and in step 116, immediately before. If it is determined that the history of the virtual intersection of No exists, step 262.
At, the color change pattern stored in advance in the ROM 22 or the like is read. Next, in step 264, the selection process is performed, and the color of the corresponding selection button 26 is changed to the color corresponding to the position of the virtual intersection.

Here, as shown in FIG. 7 (see the selection button 26 at the upper right of FIG. 7), in the present embodiment, when the virtual intersection is at the approximate center position of the selection button 26,
In step 264, so-called color reversal processing is performed.

On the other hand, when the virtual intersection is near the periphery of the selection button 26 or at a position other than the selection button 26 in the first selection area 28 including the selection button 26, the original color (that is, not selected). The color of the selection button 26 is changed to an intermediate color between the color of the selected button 26 and the color of the inverted state (see the selection button 26 at the upper right of FIG. 17).

Thus, by observing the color of the selection button 26, the screen 14 of the selection button 26 to be selected is displayed.
The degree of deviation between the position on the touch panel 42 and the position of the finger 62 on the touch panel 42 can be grasped, and how much the finger 62 should be moved with respect to the selection button 26 to be selected can be grasped.

On the other hand, when it is determined in step 130 that the virtual intersection is located in the second selection area 30,
In step 266, the position of the current virtual intersection is compared with the position of the previous virtual intersection based on the history of the previous virtual intersection. Next, in step 268, if the position of the current virtual intersection is displaced with respect to the position of the previous virtual intersection, the process proceeds to step 264 via step 262.

As a result, for example, the position of the virtual intersection immediately before is present at either the center of the selection button 26 or within the range of the same first selection area 28 excluding the center of the selection button 26. If either is the other, the color of the selection button 26 is changed. Thereby, the touch panel 42
It can be grasped that the position of the finger 62 above approaches the approximate center of the select button 26 or separates from the approximate center of the select button 26.

By the way, the finger 62 on the touch panel 42
As another means for grasping the position of the position on the screen 14 of the monitor television 12, for example, a pointer imitating an arrow mark or the like is used as a finger 6 on the touch panel 42.
There is a configuration in which it is moved on the screen 14 in conjunction with the movement of 2.

However, in this configuration, when the pointer overlaps the selection button 26, the characters or symbols displayed on the selection button 26 may be difficult to see.

Further, in the configuration to which the pointer is applied, when the shape of the selection button 26 is made small, the pointer is not made small so that the selection button 26 is largely overlapped with the selection button 26 and the selection button 26 becomes difficult to recognize, The pointers may overlap so as to straddle a plurality of matching selection buttons 26, and it may be difficult to understand the selection state. However,
If the pointer is made small, it becomes difficult to recognize the pointer itself.

On the other hand, in the present embodiment, the position of the finger 62 on the touch panel 42 can be grasped by changing the color of the selection button 26, so that the characters, symbols, etc. displayed on the selection button 26 can be seen. There is no difficulty, and it is possible to easily grasp which selection button 26 is in the selected state, and the operability is extremely high.

In this embodiment, a monitor television is applied to the arrival signal transmitting means, and the selection button 26 is used for the arrival signal.
However, the configuration of the arrival signal transmitting means and the arrival signal is not limited to this.

For example, a speaker may be applied to the arrival signal transmitting means, a sound may be applied to the arrival signal, and the scale (frequency of the sound) may be changed according to the position of the virtual intersection.

Further, for example, the controller 36 is provided with a motor as an arrival signal transmitting means in which an eccentric mass body is fixed to the rotating shaft, and the controller 36 is caused to generate vibration as an arrival signal by operating the motor. Vibration is transmitted to the hand touching the controller 36 via, and the rotation speed of the motor is changed according to the position of the virtual intersection, and vibration of a different mode is transmitted to the hand according to the position of the virtual intersection. May be

<Fifth Embodiment> Next, the fifth embodiment of the present invention will be described.
The embodiment will be described.

The outline of the configuration of the center control device 250 to which the screen operation device according to the present embodiment is applied is basically the same as the configuration of the first embodiment shown in FIG. However, in the present embodiment, as shown in the flowchart of FIG. 18, when the determination is negative in step 274, that is, when the current position of the virtual intersection is in the cancel zone 34, step 1
In step 42, the selection canceling process and the color restoring process of the selection button 26 are performed. On the other hand, if the determination is affirmative in step 274, the process proceeds to step 136.

As described above, in this embodiment, the selection is canceled when the virtual intersection is located in the cancel zone 34 in the first selection area 28, and the virtual intersection is moved when the virtual intersection is located in the gray zone 32. Deselect or maintain selection depending on history. Therefore, even if the unintended movement of the finger 62 occurs, the selection button 26 is displayed in an appropriate color, and the operability is improved.

In the first to fifth embodiments described above, if step 134 is affirmed, it is judged whether the immediately preceding history is the cancel zone 34 of the other first selection area 28, and the immediately preceding history is the other one. In the case of the cancel zone 34 of the first selection area 28, it is determined whether or not the selection button 26 of the other first selection area 28 has been selected and color changed, and if it has been selected and color changed, step 142. Alternatively, the selection state of the other first selection area 28 may be canceled and the process may proceed to step 120 if the selection and color change processing has not been performed.

If step 134 is denied,
The previous history is the gray zone 32 of the other first selection area 28.
If the previous history is the gray zone 32 of the other first selection area 28, it is determined whether or not the selection button 26 of the other first selection area 28 has been selected and color changed, If the selection and color change processing has been performed, the process proceeds to step 142 and the other first selection area 28.
It is also possible to cancel the selection state of and to proceed to step 120 if the selection and color change processing has not been performed.

[0135]

As described above, according to the present invention, it is possible to reduce the uncomfortable feeling at the time of operation and improve the operability.
