Japanese Patent Laying-Open No. 2005-04058

  However, in the information presentation apparatus as described above, although the predetermined information can be transmitted to the user by realizing a predetermined raised height in a predetermined area by a plurality of tactile pins, the user operates the touch panel. In the above, the degree of freedom for freely setting feedback information for the user from the device such as operation reaction force corresponding to the user, and the arrangement and form of the operation unit constituted by a plurality of tactile pins on the touch panel, that is, the switch type Increase the degree of freedom to match the user's preferences, and in turn, not be able to realize the degree of freedom that induces a series of user operations, and make it more user-friendly to meet the diversifying market needs There was a problem that it was not possible.

  In view of the above problems, an object of the present invention is to provide a user-friendly information presentation apparatus that can meet diversified market needs.

To solve the above problem,
An information presentation apparatus according to the present invention is:
An operation surface, a drive unit that forms an operation unit with unevenness at an arbitrary position on the operation surface, an operation history detection unit that detects an operation history given to the operation unit, and the operation history or a predetermined operation Control means for controlling the drive means based on a guidance procedure is provided.

here,
It is preferable that the driving means is a plurality of tactile pins arranged in a matrix and capable of adjusting a raised height and a reaction force, and the control means controls the raised height and the reaction force of the tactile pin.

  The raised height is a height at which the tactile pin is raised from the operation surface to the user side by adjusting a relative displacement between a piston and a cylinder constituting the tactile pin, and the reaction force Is a stress fed back to the user when the operation unit is pressed by the user.

  According to this, on the basis of the user's operation history made on the operation surface of the information presentation device or a predetermined operation guidance procedure, the height of the ridges and the reaction force arranged in a matrix are generated by the control means. By controlling the driving means including a plurality of adjustable tactile pins, the operation unit on the operation surface is controlled, and the operational feeling and the operability corresponding to the operation history are fed back to the user. It can be perceived by touch.

  Thereby, the user can perceive the relevance and transition of a series of operations, and the relevance can be given to the series of operations of the user. Alternatively, the information presenting device can respond to the user with a tactile sensation with respect to a series of operation histories and can perform operation guidance. At the same time, the degree of freedom can be increased by changing the position, size, and shape of the operation unit on the operation surface. By these things, the said information presentation apparatus can be made more user-friendly.

  Here, the operation history may be a pressing operation. In this case, it is preferable that the reaction force of the plurality of tactile pins corresponding to the pressing portion of the operation unit is smaller than the reaction force of the plurality of tactile pins in the peripheral portion of the pressing portion.

  According to this, in the information presentation device, by making the reaction force at the pressing portion of the operation portion smaller than the reaction force at the peripheral portion with respect to the user's pressing operation on the operation portion, The user is made to perceive the area of the pressing portion by touch, and the user's operation is guided so as to press only the pressing portion of the operation unit, and feedback information for the user's pressing operation of the operation unit is provided to the user. It can be given and the user's sense of pressing operation can be enhanced.

  The reaction force of the plurality of tactile pins corresponding to the pressing portion of the operation unit may be changed in accordance with the stroke of the pressing operation.

  According to this, the reaction force of the tactile pin is increased at a position where the stroke of the pressing portion of the operation unit is long, and the user is made to perceive the end or stage of the pressing operation by tactile sense. The feedback information for the pressing operation of the operation unit can be provided to the user, and variations of the feedback information can be diversified, and the user's sense of pressing operation can be enhanced.

  Or it is good also as changing the protruding height of tactile pins other than the said tactile pin corresponding to the press part of the said operation part.

  According to this, the operation part on the operation surface is used for the on / off of a conventional mechanical switch form, for example, an electric lamp for home use. By pressing alternately, it is possible to imitate a switch that turns on and off the lamp, and the user's operational feeling can be further enhanced.

here,
The operation history may be a movement operation.

In this case,
The operation unit may be moved in the direction of the moving operation. According to this, when the operation history of the user with respect to the operation unit is a moving operation for moving the operation unit, the operation unit is moved in the direction of the moving operation, and the operation unit is moved to the operation surface. The operation feeling of the user can be enhanced by imitating a so-called slide switch that moves in the surface direction or a switch such as a dial that adjusts a control amount such as a volume.

Furthermore, in the information presentation device,
The operation unit may be moved from a first predetermined position on the operation surface to a second predetermined position.

  According to this, by moving the operation unit on the operation surface, for example, the information presentation device presents a series of operations to the user, and then the operation unit to be operated next, The next operation can be guided.

  Furthermore, when the operation unit is moved from the first predetermined position to the second predetermined position, the size or shape of the operation unit may be changed.

  According to this, by moving the operation unit on the operation surface, for example, the information presenting apparatus presents a series of operations to the user, and then an operation unit to be operated next, and one step before The operation unit of this time can be differentiated from the operation unit that has been operated to make the user perceive it by touch.

  In the information presentation device described above, the operation surface may include a display surface. According to this, it is possible to make the user perceive the position of the operation unit by the visual information on the display surface.

  ADVANTAGE OF THE INVENTION According to this invention, the user-friendly information presentation apparatus corresponding to the diversified market needs can be provided.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram showing an embodiment of an information presentation apparatus according to the present invention. FIG. 2 is a schematic block diagram showing an embodiment of the information presentation apparatus according to the present invention. FIG. 3 is a schematic diagram showing an embodiment of the information presentation apparatus according to the present invention.

  An information presentation device 1 according to the present invention includes a touch panel device 2 and a main control device 3. The touch panel device 2 arranges a display surface 4, actuators 5 arranged in a matrix, and sensors 6 in this order. The main controller 3 includes a calculation unit 3a, a sensor control unit 3b, an actuator control unit 3c, and a display control unit 3d.

  The display surface 4 is composed of, for example, a flexible organic electroluminescence display (EL) to constitute an operation surface. The organic EL is a display using a substance that emits light when a voltage is applied, and is configured by vapor-depositing a light emitter made of an organic substance such as diamines on a glass substrate. In addition to constituting the surface, it has a function of visually perceiving the position of the switch by changing the luminance and color of the portion corresponding to the switch constituted by the matrix-like actuator 5 described later.

  The actuator 5 includes a cylinder, a piston, and an adjustment mechanism (not shown) that can adjust the relative displacement of the piston with respect to the cylinder, and directs the central axis thereof in a direction perpendicular to the display surface 4, that is, the operation surface. The cylinder side is fixed to the surface of the sensor 6 and the piston side is arranged to face the back surface of the display surface 4.

  The actuator 5 constitutes a tactile pin, and the actuators 5 arranged in a matrix form are driven to form an operation part, specifically a switch, by unevenness at an arbitrary position on the display surface 4, that is, the operation surface of the information presentation device 1. Configure the means. Specifically, an electrostatic type, an electromagnetic type, a piezoelectric element type, or the like can be used as the adjustment mechanism. This adjustment mechanism is driven based on the control of an actuator control unit 3c described later, and the height of the protrusion of the actuator 5 is reduced. Force (output) is controlled. The flexible display surface 4 is deformed following the unevenness of the driving means.

  The sensor 6 detects an operation history (input) given by the user to the display surface 4, that is, the operation surface together with a pressure change and a position. Although details are not shown here, the pressure applied by the operation history is detected. When it changes, it comprises a pressure-sensitive conductive rubber layer whose conductivity changes, and a vertical and horizontal horizontal electrode.

  The main control device 3 is composed of, for example, a CPU, a ROM, a RAM, and a data bus that interconnects them. The main control device 3 performs each control described below in accordance with a program stored in the ROM. The controller 3b, the actuator controller 3c, and the display controller 3d are configured.

  The sensor control unit 3b constitutes an operation history detection unit that detects an operation history given by the user detected by the sensor 6, and outputs the detection result to the calculation unit 3a. The calculation unit 3a stores a predetermined position and shape of the switch as a bulge map, and stores the reaction force of each actuator 5 as a stress map and a stress transition map. An operation received from the bulge map from the sensor control unit 3b Based on the history, the uplift map before and after the update, the stress map, and the stress transition map are output to the actuator control unit 3c. The actuator control unit 3c uses the uplift map, the stress map, and the stress transition map to form a matrix. The control means for controlling the height and reaction force of the actuator 5 is configured. The display control unit 3d performs control to change the luminance and color of the portion corresponding to the switch on the display surface 4 described above.

  Thus, for example, a pressing type thin columnar circular switch A as shown in FIG. 3 is constituted by a plurality of actuators 5 arranged in a matrix, and constitutes an operation unit. When the user's finger presses the circular switch A and the piston of the actuator 5 in the portion constituting the circular switch A is pressed down, the reaction force of the actuator 5 is controlled based on the pressed stroke. A specific example of the reaction force control will be described below.

  FIG. 4 is a schematic diagram showing the control contents of one embodiment of the information presentation apparatus according to the present invention, and FIG. 5 is a flowchart showing the control contents of one embodiment of the information presentation apparatus according to the present invention.

  As shown in FIG. 4, in this information presentation device 1, in a steady state before the user performs a pressing operation, an outward map of the information presentation device 1 is used by using a bump map as shown in FIG. When viewed from above, the raised heights of the plurality of actuators 5 on the outer peripheral side of the circular switch A are set to 0, and the raised heights of the plurality of actuators 5 constituting the circular switch A on the inner peripheral side of the circular switch A are set to 1.

  In addition, by using the stress map as shown in FIG. 4C, the reaction force of the plurality of actuators 5 in the region (attribute) of Type 1 corresponding to the pressing portion by the user's finger of the circular switch is expressed as the peripheral edge of the pressing portion. It is smaller than the reaction force of the plurality of actuators 5 in the region (attribute) of Type 2 that is a portion.

  Further, in the process in which the user performs a pressing operation and the pistons of the plurality of actuators 5 constituting the circular switch A are pressed down and the protruding height decreases based on the stroke of the pressing operation, the reaction force corresponding to the protruding height is In the Type 1 region, as shown in FIG. 4D, the raised height is a constant value from 1 to a predetermined value α, and when the raised height is smaller than the predetermined value α, it gradually becomes larger than the fixed value. The reaction force of the plurality of actuators 5 is changed in correspondence with the stroke of the pressing operation so that the maximum value is reached and the maximum height is 0 in the vicinity of 0.

  Such control is executed by the main controller 3, and the main control contents of the main controller 3 will be described with reference to the flowchart shown in FIG.

  In S1, whether or not the sensor control unit 3b has detected (sensed) the user's operation history by the sensor 6 is determined by the calculation unit 3a. If there is a detection, the process proceeds to S2, and if not, the process proceeds to S5. In S2, the actuator control unit 3c detects the pressing depth of the pressed portion of the circular switch A, that is, the height of protrusion of the actuator 5, outputs the detection result to the calculation unit 3a, and the calculation unit 3a evaluates the pressing depth.

  In S3, the calculation unit 3a acquires the attribute (Type 1 or 2 region) from the stress map, and proceeds to S4. The calculation unit 3a acquires the stress from the stress transition map and proceeds to S5. In S5, the calculation unit 3a The elevation height is acquired from the elevation map, and the process proceeds to S6. In S6, the calculation unit 3a outputs the stress and the elevation height to the actuator control unit 3c, and the actuator control unit 3c determines the elevation heights of the plurality of actuators 5 based on these.

  Further, the reaction force of the plurality of actuators 5 corresponding to the pressing portion of the circular switch A that is the operation unit, that is, the region of Type 1, is set to be smaller than the reaction force of the plurality of actuators 5 in the peripheral portion of the pressing portion, that is, the region of Type 2. Thus, the user's operation is performed so that the user senses that the type 1 region of the pressing portion of the circular switch A is easier to press than the type 2 region by tactile sense, and presses only the pressing portion of the circular switch A. While guiding the operation, it is possible to give the user feedback information for the pressing operation of the circular switch A, and the user's feeling of pressing operation can be enhanced.

  In addition, the reaction force of the plurality of actuators 5 corresponding to the pressing portion of the circular switch A is changed corresponding to the stroke of the pressing operation, and the reaction force of the actuator 5 is at a position where the stroke of the pressing portion of the circular switch A is long. , And the user can perceive the end of the pressing operation by touch. Thereby, while responding to the pressing operation of the circular switch A by the user, that is, giving feedback information to the user, variations of the feedback information can be diversified, and the user's feeling of pressing operation can be enhanced.

  After the pressing operation of the region β by the user, as shown in the right of FIG. 6, the pattern of the protruding heights of the plurality of actuators 5 in the region γ is set to the region β with respect to the pattern of the protruding heights of the region β before pressing. It is changed so as to be line symmetric at the boundary line of the region γ. Similarly, the raised height pattern of the plurality of actuators 5 in the region β is changed so as to be line symmetric with respect to the raised height pattern of the region γ before pressing at the boundary line between the region β and the region γ. .

  After the pressing operation of the region β, and after the user further presses the region γ, the ridge pattern is formed in a wedge shape as shown in the left of FIG. 6, and the plurality of actuators 5 in the adjacent region γ are The raised pattern is a flat plate.

  Further, when the user performs the moving operation of the circular switch A, the piston of the actuator 5 in the portion located on the opposite side to the moving operation direction among the plurality of actuators 5 constituting the Type 4 region of the circular switch A is the user's finger. Since the sensor 6 detects the pressure by being pressed down by this, the pressed position is detected as the pressed position as shown in FIG. 7E or FIG. 7F, and the center of the circular switch A is detected from this pressed position. A direction toward the coordinates (cx, cy) is detected as a moving direction as shown in FIG. 7E or 7F, and an arbitrary direction in the same direction with respect to the raised portion of the actuator 5 constituting the circular switch A As shown in FIG. 7B, the circular switch A is moved in the same direction at a speed corresponding to the speed of the user's finger. That is, as shown in FIG. 7B, the actuator 5 on the front side in the movement direction of the circular switch A is raised, and the actuator 5 on the rear side in the movement direction is settled.

  In addition, when the region Type 4 and the region Type 3 are pressed down simultaneously, the circular switch A is turned on in response to the pressing force by the user's finger inputted near the center of the switch A by reversing the moving direction. Can be moved.

  Such control is executed by the main controller 3, and the main control contents of the main controller 3 will be described with reference to the flowchart shown in FIG.

  In S11, it is determined by the arithmetic unit 3a whether or not the sensor control unit 3b has detected (sensed) the user's operation history by the sensor 6, and the process proceeds to S12 when there is a detection, and proceeds to S15 when there is no detection. In S12, the actuator control unit 3c detects the pressing depth of the pressing portion of the circular switch A, particularly the type 4 region, that is, the height of the actuator 5, and outputs the detection result to the calculating unit 3a.

In S18, the calculation unit 3a outputs the stress and the height of the bump to the actuator control unit 3c. Based on these, the actuator control unit 3c controls the heights and stresses of the plurality of actuators 5.

  According to this, when the operation history of the user with respect to the circular switch A which is the operation unit is a moving operation for moving the circular switch A, the circular switch A is moved by moving the circular switch A in the direction of the moving operation. The user's operational feeling can be enhanced by imitating a so-called slide switch that moves in the surface direction on the operation surface or a switch such as a dial that adjusts a control amount such as a volume.

  Further, when the user performs an upward movement operation of the rectangular switch B, the pistons of the actuators 5 of the plurality of actuators 5 constituting the region of Type 7 below Type 6 of the rectangular switch B are pushed down by the user's finger. Since the sensor 6 detects the pressure, the depressed position is detected as a pressed position, the upward direction from the pressed position is detected as the moving direction, and the raised portion of the actuator 5 constituting the rectangular switch B is detected. On the other hand, given an arbitrary acceleration in the same direction, the rectangular switch B is moved upward at a speed corresponding to the speed of the user's finger.

  In addition, when the region Type 7 and the region Type 5 are pressed down at the same time, the rectangular switch B is made to correspond to the pressing force by the user's finger inputted near the center of the switch A by reversing the moving direction. Can be moved.

  According to this, when the user's operation history with respect to the square switch B which is the operation unit is a moving operation for moving the square switch B, the square switch B is moved by moving the square switch B in the direction of the moving operation. The user's operational feeling can be enhanced by imitating a so-called slide switch that moves in the surface direction on the operation surface or a switch such as a dial that adjusts a control amount such as a volume.

  In addition, it is possible to input a direction in an analog manner by a user's finger using the square switch B, and the information presentation device 1 can be used for dimming of a lighting device having relatively few gradations or a stepless wiper such as an intermittent wiper. It can be used as an input mechanism.

  In the above-described fourth embodiment, the rectangular switch B is divided into three regions, and the configuration in which the user's moving operation is detected as pressure in the upper and lower regions is shown. It is also possible to detect a movement operation on the operation surface as a pressing operation. This will be described below.

  FIG. 11 is a schematic diagram showing the control contents of an embodiment of the information presentation apparatus according to the present invention.

  Further, when the user performs the movement operation of the circular switch A, the pistons of the actuators 5 of the plurality of actuators 5 constituting any region of the Type 4 of the circular switch A are pushed down by the user's finger, and the sensor 6 applies pressure. Therefore, the circular switch A is configured by detecting the depressed position as a pressed position, and detecting the circumferential direction with a line segment connecting the pressed position as a radius as a moving direction. An acceleration in the same direction is applied to the raised portion of the actuator 5, and the circular switch A is moved in the circumferential direction at a speed corresponding to the speed of the user's finger.

  According to this, when the operation history of the user with respect to the circular switch A which is the operation unit is a moving operation for moving the circular switch A, the circular switch A is moved by moving the circular switch A in the direction of the moving operation.

Further, the circular switch A that is a raised portion constituting the operation unit is moved from the first predetermined position C on the operation surface to the second predetermined position E, and the circular switch A that is the operation unit is moved to the first predetermined position C. In moving from the predetermined position C to the second predetermined position E, the size of the circular switch A as the operation unit is changed. Of course, the shape may be changed.

  According to this, by moving the circular switch A which is an operation unit on the operation surface, for example, the information presentation device 1 presents a series of operations to the user, and then an operation unit to be operated next, The next operation can be guided to the user. In addition, by moving the circular switch A, which is an operation unit on the operation surface, the information presentation apparatus 1 presents a series of operations to the user, and then presents a switch that is the operation unit to be operated next. The current operation unit can be differentiated from the operation unit operated before the stage, and the user can perceive it by touch.

  More specifically, when there is an incoming call to the in-vehicle phone, a user's finger is guided to the answer button, and a specific operation such as “decision” or “cancel” is performed for the operation operated by the user. When necessary, specific switches that select those specific operations can be made to allow the user's finger to be guided and perceived by the sense of touch. Further, on the initial screen immediately after the user purchases the car, the user can perceive the switch to be operated first by tactile sense. In addition, when performing an operation tutorial (operation guidance, teaching), the position of the switch can be explicitly communicated to the user by various sections.

  Thereby, the user can perceive the relevance and transition of a series of operations, and the relevance can be given to the series of operations of the user. In addition, the information presentation device 1 can respond to the user with a tactile sense with respect to a series of operation histories, and can perform operation guidance. By these things, the information presentation apparatus 1 can be made more user-friendly.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions are made to the above-described embodiments without departing from the scope of the present invention. be able to.

  For example, the actuator 5, i.e., the tactile pin, may have a configuration other than a configuration including a piston and a cylinder, and forms an unevenness on the operation surface such as an electrostatic type, an electromagnetic type, or a piezoelectric element. Any format can be used as long as it can be used. The sensor 6 is not limited to the matrix detection method described in the above-described embodiment as long as it can detect the pressure and the operation position by the user's finger on the operation surface. Various types such as a method, a capacitance detection method, and an optical detection method can be adopted.

  Moreover, as a specific mounting form in the vehicle of the information presentation apparatus 1 of the above-described embodiment, the following form can be taken as an example. FIG. 13 is a schematic diagram showing an application example of the information presentation apparatus according to the present invention to a vehicle.

  As shown in FIG. 13, the information presentation device 1 according to the present invention can be arranged at, for example, the position of 10:10 on the handle or the position of the armrest on the center console. In addition, information can be presented to the user from the in-vehicle device without stopping the user from viewing the front.

  In particular, in the conventional vehicle, the switch for operating various in-vehicle devices such as the shift operation, the operation of the car navigation device, and the air conditioner is concentrated on the front portion of the vehicle. By using, it is possible to make the switch arrangement easier and to reduce the number of apparent switches.
