Description

  The present invention relates to an input device that enables an input operation by an operation body such as a finger, such as a touch pad or a touch panel.

  As a conventional input device, for example, the one described in Patent Document 1 is known. The input device (the tactile sense presentation device) of Patent Document 1 is provided at another position with respect to the display device, and detects the operation position of the finger on the operation surface (operation detection unit), and the detection result of the touch pad And an actuator (oscillator) that controls the frictional force between the finger and the operation surface, and a controller that controls the operation of the actuator. The input device is a device that enables input to an icon (operation button) displayed on the display device by performing finger operation on the touch pad.

  On the touch pad, an area corresponding to the icon of the display device is defined as a target area, and an area corresponding to the periphery of the icon is defined as the peripheral area. Then, when the finger moves on the operation surface of the touch pad, passes from the area other than the peripheral area to the peripheral area, and reaches the target area, in the peripheral area, the actuator is activated by the control unit to generate vibration. It is supposed to be

  When the finger moves in an area other than the peripheral area, no vibration occurs and a predetermined frictional force is generated on the finger. In addition, when the finger passes through the peripheral area, the occurrence of vibration generates a squeeze effect between the finger and the operation surface, and the frictional force of the finger on the operation surface is reduced. At this time, the moving speed of the finger is increased. Furthermore, when the finger moves in the target, no vibration occurs and a predetermined frictional force is generated on the finger. Therefore, when the operator operates the finger so as to pass through the peripheral area from the area other than the peripheral area to reach the target area, the frictional force is reduced in the peripheral area so that a feeling of retraction is recalled into the target area. It has become.

  However, the moving speed of the finger when the operator operates the finger is different for each person. In addition, there are individual differences in the time taken to stop the finger on the target due to the feeling of retraction obtained by vibration and the feeling of retraction. Therefore, the position where the finger is stopped after the pull-in operation may deviate from the expected position (for example, the center position) in the target, and the next finger operation is started to start the next finger operation. The difference between fast and slow until a feeling of retraction is obtained, that is, a difference in the feeling of operation, occurs. Alternatively, if the position of the stopped finger is within the target and close to the peripheral area, vibration may be generated or the vibration may be stopped with slight finger movement. Can occur. Therefore, the operator feels uncomfortable.

First Embodiment
The input device 100 of the first embodiment is shown in FIGS. The input device 100 of the present embodiment is applied to, for example, a remote control device for operating the navigation device 50. The input device 100 is mounted on the vehicle 10 together with the navigation device 50. The navigation device 50 corresponds to a predetermined device of the present invention.

  The navigation device 50 is a route guidance system that displays current position information of the vehicle on a map, traveling direction information, guidance information to a destination desired by the operator, and the like. The navigation device 50 has a liquid crystal display 51 as a display unit. The liquid crystal display 51 is disposed at the center of the instrument panel 11 of the vehicle 10 in the vehicle width direction, so that the display screen 52 can be viewed by the operator.

  The navigation device 50 is formed separately from the input device 100, and is set at a position away from the input device 100. The navigation device 50 and the input device 100 are connected by, for example, a Controller Area Network bus (CAN bus (registered trademark)).

  On the display screen 52 of the liquid crystal display 51, the position of the vehicle on the map is displayed, and various operation buttons 52a1 to 52a4 for operating the navigation device 50 are displayed (FIGS. 4 and 9). ). The various operation buttons 52a1 to 52a4 are, for example, buttons for enlarged display, reduced display of a map, and destination guide setting, etc., and the first operation button 52a1, the second operation button 52a2, the third operation button 52a3, and The fourth operation button 52a4 and the like are provided. The various operation buttons 52a1 to 52a4 are so-called operation icons. Further, on the display screen 52, for example, a pointer 52b (display screen 52) designed in an arrow shape so as to correspond to the position of the operator's finger F (operating body) on the operation unit 110 (operation surface 111) described later. The upper coordinate position is displayed.

  In the display screen 52, an area between the various operation buttons 52a1 to 52a4 is defined as an intermediate area ca. Then, a predetermined position (for example, a center position or an arbitrary position in the middle) in the middle area ca is defined as the middle position cp.

  Further, in the present embodiment, the coordinate position of the finger F on the operation surface 111 and the coordinate positions of the various operation buttons 52a1 to 52a4 and the pointer 52b on the display screen 52 are associated with each other.

  The input device 100 is provided at a position adjacent to the arm rest 13 at the center console 12 of the vehicle 10, as shown in FIGS. 1 to 4, and is disposed in a range easily accessible by the operator. The input device 100 includes an operation unit 110, a drive unit 120, a control unit 130, and the like.

  The operation unit 110 forms a so-called touch pad, and is a part that performs an input operation on the navigation device 50 with the finger F of the operator. The operation unit 110 includes an operation surface 111, a touch sensor 112, a housing 113, and the like.

  The operation surface 111 is exposed to the operator side at a position adjacent to the armrest 13 and is a flat portion where the operator performs a finger operation. For example, a material or the like for improving the slip of the finger over the entire surface is provided It is formed by

  On the operation surface 111, an input for operation (selection, depression determination, and the like) on various operation buttons 52a1 to 52a4 displayed on the display screen 52 is set by an operator's finger operation. Around the operation surface 111, a rib 111a extending to the side opposite to the operation side is provided.

  The touch sensor 112 is, for example, a capacitance type detection unit provided on the back surface side of the operation surface 111. The touch sensor 112 is formed in a rectangular flat plate shape, and is configured to detect an operation state of the sensor surface by the finger F of the operator.

  The touch sensor 112 is formed by arranging electrodes extending along the x-axis on the operation surface 111 and electrodes extending along the y-axis in a grid. These electrodes are connected to a control unit 130 described later. Each electrode is configured such that the generated capacitance changes in accordance with the position of the finger F of the operator in proximity to the sensor surface, and the signal (sensitivity value) of the generated capacitance is a controller It is output to 130. The sensor surface is covered by an insulating sheet made of an insulating material. The touch sensor 112 is not limited to the above-described electrostatic capacitance type, and various types such as other pressure-sensitive types can be used.

  The housing 113 is a support portion that supports the operation surface 111 and the touch sensor 112. The housing 113 is formed in a frame shape, and is disposed, for example, inside the center console 12.

  The drive unit 120 vibrates the operation surface 111 in the expanding direction of the operation surface 111 in two axial directions of the x and y axes, and at least one of four sides around the operation surface 111, the rib 111a and the housing It is provided between them. The drive unit 120 is connected to a control unit 130 described later, and the control unit 130 controls vibration generation.

  The driving unit 120 generates vibration in one axial direction (x-axis direction or y-axis direction) on the operation surface 111 by validating vibration in only one axial direction among the two axial directions. By simultaneously making vibration in two axial directions effective, it is possible to generate an oblique vibration in which both vibrations are combined on the operation surface 111.

  As the drive unit 120, it is possible to use, for example, an electromagnetic actuator such as a solenoid or a voice coil motor, or a vibrator such as piezo, or a combination of the vibrator and a spring. For example, if one vibrating body generates vibrations in two axial directions, the driving unit 120 is formed by providing one vibrating body on at least one of the four sides around the operation surface 111. be able to. Alternatively, if the vibrator generates vibration in only one axial direction, the drive unit 120 may be provided by providing one vibrator (two in total) on two adjacent side portions around the operation surface 111. Can be formed. Alternatively, the drive unit 120 can be formed by providing a combination of a vibrating body in one axial direction and a spring on opposing sides and providing two sets of vibration directions crossing each other. In the present embodiment, as shown in FIG. 3, in the drive unit 120, vibrators are provided on four sides around the operation surface 111.

  The control unit 130 includes a CPU, a RAM, a storage medium, and the like. The control unit 130 acquires the contact position (coordinate position of the finger F), the movement direction, the movement distance, and the like of the finger on the operation surface 111 as the operation state of the finger F of the operator from the signal obtained from the touch sensor 112 Do. The control unit 130 also calculates the coordinates of the pointer 52 b on the display screen 52 based on the acquired touch position of the finger F, and causes the display screen 52 to display the pointer 52 b. In addition, the control unit 130 acquires, as an operation state, the presence or absence of the pressing operation on any of the operation buttons on the operation surface 111, and the like.

  Then, the control unit 130 controls the generation state of the vibration by the drive unit 120 according to the operation state. In addition, a vibration control parameter (vibration map) at the time of vibration control is stored in advance in the storage medium of the control unit 130, and the control unit 130 performs vibration control based on the vibration control parameter. There is. Further, the control unit 130 performs another operation when the coordinate position of the pointer 52b on the display screen 52 enters the area of another operation button (52a2) from any of the operation buttons (52a1) by vibration control. The coordinate position of the pointer 52b in the button (52a2) is moved to a predetermined position (for example, the center position cb of the operation button) to update the coordinate data (described in detail later).

  The configuration of the input device 100 according to the present embodiment is as described above, and the operation and effect will be described below with reference to FIGS.

  First, based on the flowchart shown in FIG. 5, the control unit 130 controls pulling in to the operation area which is the movement destination of the finger F. In step S100, the control unit 130 determines whether the finger F of the operator touches (touches) the operation surface 111 based on a signal (operation state of the finger F) obtained from the touch sensor 112. The control unit 130 repeats step S100 if determined as negative, and proceeds to step S110 if determined affirmative. As shown in FIGS. 4A and 4B, when the finger F of the operator is touched on the operation surface 111, the display of the pointer 52b on the display screen 52 becomes effective, and the operation on the operation surface 111 is performed. The pointer 52 b is displayed on the display screen 52 so as to correspond to the position of the person's finger F.

  Hereinafter, as shown in FIG. 4B, the case where the position on the display screen 52 corresponding to the finger F is moved from the first operation button 52a1 to the second operation button 52a2 will be described as one model.

  In step S110, the control unit 130 controls the second operation button 52a2 (another operation button) on the first operation button 52a1 (any operation button) of the operator's finger F among the various operation buttons 52a1 to 52a4. Determine if it is moving or stopped. If the control unit 130 determines that the finger F is moving, the process proceeds to step S120, and if it is determined that the finger F is stopped, the process proceeds to step S140.

  In step S120, the control unit 130 calculates a vector between the current position of the pointer 52b and the closest operation button (second operation button 52a2). In calculating the vector, the control unit 130 determines the distance between the position of the pointer 52b and the second operation button 52a2 (the length of the vector) and the direction (direction of the vector) from the position of the pointer 52b toward the second operation button 52a2. calculate.

  Then, in step S130, the control unit 130 drives to draw (guide) the operator's finger F from the first operation button 52a1 to the second operation button 52a2 according to the vector (length and direction). The unit 120 is driven to generate vibration on the operation surface 111. First, the control unit 130 causes the operation surface 111 to generate a vibration that reciprocates in the direction of the vector (the direction of the movement destination of the operation body) with respect to the drive unit 120.

  Here, since the operation buttons 52a1 to 52a4 are set to line up in the x-axis direction, the direction of the vector is the x-axis direction, and the control unit 130 generates vibration along the x-axis direction.

Then, as shown in FIG. 6, according to the movement position of the finger F, the control unit 130 sets the vibration intensity between the first operation button 52a1 and the second operation button 52a2 (in the middle of the middle area ca). , Control to form the maximum value. The control unit 130 makes a linear change when giving the maximum value to the vibration intensity.

  In FIG. 4A, the intermediate position cp in the intermediate area ca is displayed at the central position between the first operation button 52a1 and the second operation button 52a2 for better understanding. The intermediate position cp is not limited to the center position of both operation buttons 52a1 and 52a2, and may be any position between the first operation button 52a1 and the second operation button 52a2 (arbitrary position) And can).

  The control unit 130 responds by changing the amplitude as shown in FIG. 7 in order to give a maximum value to the vibration intensity. Specifically, the amplitude of vibration is increased by sequentially increasing the amplitude while the finger F reaches the intermediate position cp from the first operation button 52a1. The control unit 130 maximizes the amplitude at the intermediate position cp. Then, after the finger F exceeds the intermediate position cp, the amplitude is successively reduced to return to the original amplitude, thereby reducing the strength of the vibration. By such a change in amplitude, as shown in FIG. 4C, a valley of resistance is formed on the operation surface 111, and the finger F becomes an image operated (moved) while crossing over this mountain. .

  After step S130, the control unit 130 repeats steps S100 to S130 until the finger F of the operator is stopped by any operation button.

  By the steps S100 to S130, when the finger F moves from the first operation button 52a1 to the second operation button 52a2, the finger F receives resistance by the vibration generated on the operation surface 111. In addition, as the finger F moves from the first operation button 52a1 to the intermediate position cp, the magnitude of the vibration is controlled to form a maximum value, so that the resistance to the finger F increases. Further, as the finger F moves from the intermediate position cp to the second operation button 52a2, the maximum value is passed and the vibration intensity is controlled to decrease, so that the resistance to the finger F decreases.

  Therefore, the finger F gets over the resistance (the peak in FIG. 4C) at the middle position cp and reaches the second operation button 52a2, and the finger F moves from the middle position cp to the second operation button 52a2. It will receive a feeling (action) as if it were induced (retracted). The sense of guidance at this time can be reworded as a sense of overtaking the mountain.

  Thus, in the present embodiment, when the operator moves the finger F, the finger F is guided in the movement direction, and a feeling of guidance to the movement destination can be obtained.

  If it is determined that the movement of the finger F is stopped in step S110 while repeating steps S100 to S130, the control unit 130 determines in step S140 whether or not any operation button has been pressed. judge. The pressing operation is an operation indicating the determination of selection of the operation button by the operator, and is performed by the operator pressing a finger on the operation surface 111 at a position corresponding to the operation button. If an affirmation judging is carried out at Step S140, control part 130 will perform pushing decision processing at Step S150. That is, an instruction corresponding to one of the operation buttons is issued to the navigation device 50. If the negative determination is made in step S140, the process returns to step S100.

  Here, as shown in FIGS. 8 to 10, the control unit 130 controls the coordinate position (coordinate position of the pointer 52b) on the display screen 52 corresponding to the finger F to be the first operation button 52a1 by pull-in control. When entering the area of the second operation button 52a2 (the other operation button) from any of the operation buttons, the coordinate position on the display screen 52 is moved to a predetermined position in the second operation button 52a2 Correct and update to that coordinate position. The predetermined position is, for example, an inner position apart from the boundary line of the second operation button 52a2, and here, is a central position cb in the second operation button 52a2.

  Specifically, the control unit 130 moves and updates the coordinate position of the pointer 52b based on the flowchart shown in FIG.

  That is, in step S200, the control unit 130 first determines whether or not the pointer 52b has entered the area of the second operation button 52a2 (another operation button) by pull-in control. The control unit 130 makes an affirmative determination, for example, when the coordinate position of the pointer 52 b is on the boundary of the second operation button 52 a 2. If an affirmative determination is made in step S200, the process proceeds to step S210, and if a negative determination is made, the process proceeds to step S250.

In step 210, as shown in FIG. 9, the control unit 130 moves the coordinate position (internal coordinate) of the pointer 52b on the display screen 52 to the central position cb (induction point). When the control unit 130 moves the coordinate position of the pointer 52b to the center position cb, as shown in FIG. 10, the pointer 52b is continuously moved from the boundary position of the second operation button 52a2 to the center position cb. Animate to move.

  Next, in step S220, the control unit 130 increases the count number of the timer for time (timer) by one. Then, in step S230, with the coordinate position of the moved pointer 52b fixed, the control unit 130 determines whether a predetermined condition assuming that the finger F is stopped is satisfied. The predetermined condition uses a predetermined time (set timer) here. The predetermined time is set as a time taken to stop after the finger F is pulled from the first operation button 52a1 to the second operation button 52a2.

  Note that as the predetermined condition, the movement speed or movement acceleration of the finger F may be used. For example, when the moving speed, the moving acceleration, and the like become zero, the predetermined condition can be satisfied.

  If an affirmative determination is made in step S230, the control unit 130 returns the count number of the timer to zero in step S240, and in step S250 the central position cb at which the coordinate position of the pointer 52b on the display screen 52 is moved in step S210. Update to If a negative determination is made in step S230, steps S220 and S230 are repeated.

As described above, according to the present embodiment, the second operation button 52 a 2 on the display screen 52 is obtained even if a shift (variation) occurs at a position where the finger F is actually stopped after the retraction control. The coordinate position in the other operation button is moved and updated to the central position cb (predetermined position). Therefore, since the start position of the finger F to be moved next is set to the center position cb of the operation button, it is possible to suppress the variation in the feeling of retraction (difference in operation feeling) generated at the time of the next finger operation. In addition, when the position of the finger F that has actually stopped is a position close to the boundary of the second operation button 52a2 (the other operation button), a vibration for retraction is generated along with a slight movement of the finger F. An unstable condition may occur such as vibration or vibration being stopped. However, since the coordinate position in the second operation button 52a2 on the display screen 52 is moved and updated to the central position cb, such a defect can be suppressed. In general, it is possible to prevent the operator from feeling uncomfortable.

  Further, in the present embodiment, the predetermined position for moving the coordinate position of the pointer 52b is set as the central position cb in the operation button. Thereby, the start position at the time of the next operation can be made more stable.

  In addition, when moving the coordinate position of the pointer 52b, the control unit 130 displays an animation so that the pointer 52b continuously moves to the central position cb. Thus, the pointer 52b does not move suddenly (like flying) from the boundary area of the second operation button 52a2 toward the center position cb, and the operator follows the movement of the pointer 52b with eyes be able to.

  The control unit 130 moves the coordinate position of the pointer 52b to the center position cb and then fixes the position, and updates the coordinate position of the pointer 52b to the center position cb when a predetermined condition assuming that the finger F stops is satisfied. I am trying to do it. As a result, the position of the pointer 52b does not move finely until the finger F stops, which makes it easy to view.

(Modification of the first embodiment)
The modification of 1st Embodiment is shown to FIG. 11, FIG. Here, in order to give a maximum value to the strength of the vibration, the control unit 130 has the same amplitude as shown in FIG. 11 and can cope with this by changing the frequency of the vibration. Specifically, while the finger F (pointer 52b) reaches the intermediate position cp from the first operation button 52a1, the vibration frequency is increased in order to increase the vibration intensity. Maximize the frequency at the intermediate position cp. Then, after the finger F (pointer 52b) exceeds the intermediate position cp, the vibration frequency is lowered and returned to the original frequency, thereby reducing the vibration intensity.

  Further, as shown in FIG. 12, the control unit 130 may change exponentially when giving the maximum value to the strength of the vibration. According to Weberfechner's law, the amount of human sense is proportional to the logarithm of the stimulus intensity, so that such an exponential change can be made more understandable to a human.

Second Embodiment
A second embodiment is shown in FIG. The second embodiment has the same configuration as the first embodiment, but at least one of the movement speed of the finger F, the movement acceleration of the finger F, the strength of a predetermined vibration during pull-in control, or a predetermined vibration pattern. Accordingly, the size corresponding to the moving direction of the finger F in the middle area ca is changed. Here, in accordance with the moving speed of the finger F, the size of the middle area ca is changed.

  That is, as shown in FIG. 13A, when the movement speed of the finger F is faster than a predetermined value, it is predicted that the distance from the middle region ca to the stop of the finger F becomes long. Therefore, by shortening the size in the movement direction of the finger F in the intermediate area ca, the position at which the finger F is stopped can be brought close to the center position cb of the second operation button 52a2 (the other operation button).

  Further, as shown in FIG. 13B, when the movement speed of the finger F is slower than a predetermined value, it is predicted that the distance from the intermediate region ca to the stop of the finger F becomes short. Therefore, by lengthening the size of the movement direction of the finger F in the intermediate area ca, the position at which the finger F is stopped can be brought close to the center position cb of the second operation button 52a2 (the other operation button).

  As described above, according to the present embodiment, by changing the size of the intermediate area ca, the stop position of the finger F due to retraction is aimed at the position on the operation button (52a2) according to the movement speed of the finger F. It can be close to (central position cb). Therefore, since the start position of the finger F to be moved next can be stabilized, it is possible to prevent the operator from feeling uncomfortable about the retraction in the next operation.

  In the present embodiment, instead of the moving speed of the finger F, the size of the intermediate area ca may be changed based on the moving acceleration of the finger F.

Third Embodiment
A third embodiment is shown in FIG. In the third embodiment, as in the second embodiment, according to at least one of the movement speed of the finger F, the movement acceleration of the finger F, the strength of a predetermined vibration during pull-in control, or a predetermined vibration pattern. The size corresponding to the moving direction of the finger F in the middle area ca is changed. Here, the size of the intermediate region ca is changed according to the strength of the predetermined vibration at the time of pull-in control.

  That is, as shown in FIG. 14A, when the magnitude (maximum value) of vibration during pull-in control is larger than a predetermined value, it is predicted that the distance from the intermediate region ca until the finger F becomes long becomes long. Be done. Therefore, by shortening the size in the movement direction of the finger F in the intermediate area ca, the position at which the finger F is stopped can be brought close to the center position cb of the second operation button 52a2 (the other operation button).

  Further, as shown in FIG. 14B, when the strength (maximum value) of vibration during pull-in control is smaller than a predetermined value, it is predicted that the distance from the intermediate region ca until the finger F is short becomes short. Be done. Therefore, by lengthening the size of the movement direction of the finger F in the intermediate area ca, the position at which the finger F is stopped can be brought close to the center position cb of the second operation button 52a2 (the other operation button).

  As described above, according to the present embodiment, as in the second embodiment, by changing the size of the intermediate region ca, the finger by the retraction is adjusted according to the intensity (maximum value) of the vibration during the retraction control. The stop position of F can be brought close to the target position (center position cb) on the operation button (52a2). Therefore, since the start position of the finger F to be moved next can be stabilized, it is possible to prevent the operator from feeling uncomfortable about the retraction in the next operation.

  In the present embodiment, the magnitude of the intermediate region ca may be changed based on the intensity pattern of vibration instead of the intensity (maximum value) of vibration during pull-in control. The intensity pattern of vibration indicates, for example, at which position in the movement direction of the finger F the maximum value of the vibration intensity is provided in the intermediate region ca.

  For example, in the case where the local maximum value of the vibration intensity is set on the side closer to the second operation button 52a2 (the other operation button) which is the movement destination, the finger F passes the local maximum value of the vibration intensity and then stops. It is predicted that the distance of Therefore, by shortening the size in the movement direction of the finger F in the intermediate area ca, the position at which the finger F is stopped can be brought close to the center position cb of the second operation button 52a2 (the other operation button).

  Conversely, if the maximum value of the vibration intensity is set closer to the first operation button 52a1 (any operation button) that is the movement source, the finger F stops after passing the maximum value of the vibration intensity. It is predicted that the distance to Therefore, by lengthening the size of the movement direction of the finger F in the intermediate area ca, the position at which the finger F is stopped can be brought close to the center position cb of the second operation button 52a2 (the other operation button).

  As a condition for changing the size of the intermediate area ca, the contents of the second embodiment and the third embodiment may be combined.
