(Regarding tactile adjustment using the tactile adjustment unit 7)
FIG. 3A is a schematic view of the operation surface of the tactile sensation presentation apparatus according to the embodiment as seen from the side surface, and FIG. 3B is a top view schematically showing a region where the operation surface vibrates. In FIG. 3A, the vertical axis represents the deflection amount x, and the horizontal axis represents the operation surface 30 in a reference state to which no excitation force is applied. Note that the vibration of the operation surface is performed not only in the positive direction of the vertical axis in FIG. 3A but also in the negative direction, but the amplitudes in the positive direction and the negative direction are substantially the same. The amplitude in the positive direction will be described. In addition, the first region 301 to the third region 303 shown in FIG. 3B do not necessarily oscillate the entire region, but schematically show a region including the oscillating region.

  A first region 301 shown in FIG. 3A is a region obtained by combining a diagonally-upward portion with a larger right-angled diagonal line and the second region 302 to the third region 303. . A second region 302 shown in FIG. 3A is a region obtained by combining the diagonally rising portion with the upper left and the third region 303. A third area 303 shown in FIG. 3A is an area of a hatched portion that rises to the right and has a narrower interval between the shaded lines.

  The tactile sense adjustment unit 7 is configured to adjust the amount of deflection of the operation surface 30 by changing the rigidity of the touch panel 3 to adjust the tactile sense.

  In addition, the tactile presentation device 1 adjusts the tactile sensation transmitted to the hand by the operator operating the tactile adjustment unit 7 instead of the excitation force applied to the touch panel 3 by the tactile presentation unit 5 being constant. If so, it is configured to be able to adjust the strength of the stimulus transmitted to the hand.

  This tactile adjustment can be performed by changing the pressure applied to the back surface 31 of the touch panel 3 via the screw shafts 715 to 745 of the tactile adjustment unit 7.

  In the state where the pressure applied to the touch panel 3 via the screw shaft 715 to the screw shaft 745 of the tactile sense adjusting unit 7 is the smallest, that is, the state where the rigidity of the touch panel 3 is the lowest, it is shown in FIGS. As described above, the first region 301 that is the entire area of the operation surface 30 mainly vibrates.

  Since this vibration is the primary mode as described above, the manner in which the operation surface 30 bends like a hemispherical surface is only in the positive direction, but is schematically shown in FIG. Hereinafter, this state is referred to as a first state.

  Here, taking the case of the first tactile adjustment unit 71 as an example, the screw shaft 715 moves in the direction of arrow C in FIG. 2A by being operated in the direction of arrow A in FIG. Thus, the first state can be created.

In this first state, as shown in FIG. 3A, the deflection amount x at the center 300 of the operation surface 30 is maximized and becomes _xmax . In this first state, since the amount of deflection is maximum, that is, the amplitude is maximum, the tactile sensation transmitted to the operator is maximum.

  When the operator operates the adjustment dial 710 to the adjustment dial 740 of the tactile sense adjustment unit 7 to move the screw shaft 715 to the screw shaft 745 against the back surface 31 of the touch panel 3, the screw shaft 715 to the screw shaft 745 are passed through. Thus, the pressure applied to the touch panel 3 increases more than in the first state. Hereinafter, a state where the pressure is between the minimum and maximum will be referred to as a second state.

  Here, taking the case of the first tactile adjustment unit 71 as an example, the screw shaft 715 is moved in the direction of arrow D in FIG. 2A by being operated in the direction of arrow B in FIG. Then, pressure is applied to the touch panel 3 to partially increase the rigidity, and the second state can be created.

In the second state, as shown in FIG. 3 (b), since the pressure applied to the screw receiving portion 310a~ screw receiving portion 310d of the touch panel 3, the deflection quantities x ₁ around the first state It is smaller than the deflection amount x ₂ near the in. This is because pressure is applied to the touch panel 3 by the screw shafts 715 to 745 and the amount of deflection around the screw receiving portions 310a to 310d is restricted. In other words, the rigidity around the screw receiving portion 310a to the screw receiving portion 310d is higher than the rigidity in the first state. As a result, in the second state, the touch panel 3 in the second region 302 having a smaller area than the first region 301 mainly vibrates. As shown in FIG. 3B, in the second region 302, since the deflection around the screw receiving portion 310a to the screw receiving portion 310d is restricted, the screw receiving portion 310a to the screw receiving portion 310d are arranged on the operation surface 30. This is the area that contains the image mapped to.

Therefore deflection amount _{x 11} at the center 300 of the operation surface 30 becomes smaller amount than the maximum amount of deflection _{x max.} In this second state, the tactile sensation transmitted to the operator is smaller than in the first state.

  Further, when the operator further operates the adjustment dial 710 to the adjustment dial 740 of the tactile adjustment unit 7 to move the screw shaft 715 to the screw shaft 745 against the back surface 31 of the touch panel 3 with the maximum amount of movement, the screw The pressure applied to the touch panel 3 via the shaft 715 to the screw shaft 745 is maximized. Hereinafter, the state where the pressure is maximum is referred to as a third state.

  Here, taking the case of the first tactile adjustment unit 71 as an example, in addition to the above-described operation, the operation is further performed in the direction of arrow B in FIG. It is possible to move in the direction of arrow D in a) and create the third state.

In this third state, for example, as shown in FIG. 3A, the amount of deflection of the screw receiving portion 310a to the screw receiving portion 310d is substantially zero, and the vibration is caused by the screw receiving portion 310a to the screw receiving portion 310d. It is defined in a third region 303 that is inside the mapping of the operation surface 30. That is, the vibration of the touch panel 3 is mainly defined in the third region 303. Deflection amount _{x 10} of the center 300 of the operation surface 30 is smaller than the deflection amount _{x 11} in the second state. Therefore, the tactile sensation transmitted to the operator is smaller than that in the second state.

  In this way, the operator operates the tactile adjustment unit 7 to adjust the tactile sense, in other words, the stimulus transmitted to the hand, from the first state where the tactile sense is maximum to the third state where the tactile sense is minimum. It becomes possible to do.

  The tactile adjustment described above has been performed by adjusting the first tactile adjustment unit 71 to the fourth tactile adjustment unit 74, but is not limited to this, and operates at least one tactile adjustment unit. Thus, the tactile sense may be adjusted.

  Below, operation | movement of the tactile sense presentation apparatus 1 is demonstrated, referring each figure.

(Operation)
First, when the power of the vehicle is turned on, the control unit 9 of the tactile presentation device 1 periodically acquires detection information from the touch panel 3.

  When detecting an operation performed on the operation surface 30 based on the detection information, the control unit 9 generates a control signal for presenting a tactile sensation to the operator and outputs the control signal to the tactile sense presenting unit 5.

  The tactile sensation providing unit 5 applies a predetermined excitation force to the touch panel 3 based on the acquired control signal.

  The operator recognizes that the operation has been accepted by feeling the vibration of the operation surface 30. If the presentation of the tactile sensation due to the vibration of the operation surface 30 is not a desired tactile sense, the operator uses at least one of the first tactile adjustment unit 71 to the fourth tactile adjustment unit 74 of the tactile adjustment unit 7, Adjust tactile sensation.

Specifically, in the haptic presentation device 1, the amount of deflection of the operation surface 30 generated based on a predetermined excitation force by the haptic adjustment unit 7 while the excitation force generated by the tactile presentation unit 5 is constant. The tactile sensation imparted to the operator can be made different by adjusting.

  This tactile sensation presentation apparatus 1 is manufactured at a low cost without requiring high-level processing such as changing a control signal in accordance with the tactile sensation to be presented because the excitation force generated by the tactile sensation presentation unit 5 is constant. can do.

  Since the operator can adjust the tactile sensation, the tactile sensation presentation apparatus 1 can adjust the strength of the stimulus transmitted to the hand, and the operability is improved as compared with the one that cannot be adjusted.

  Here, as a modified example, the tactile adjustment unit 7 is configured using a ball screw, but is not limited thereto, and can adjust a vibrating region of the touch panel 3 such as a piezoelectric element or an artificial muscle. In other words, the touch panel 3 may be configured to include an actuator that partially changes the rigidity. As an example, a plurality of the piezoelectric elements are arranged on the back surface 31 of the touch panel 3.
