<First Embodiment>
Hereinafter, the first embodiment of the control device and the input device will be described with reference to the drawings.
As shown in FIG. 1, the input device 1 includes an operation unit 2 operated by a user and a control device 3 that performs processing based on an operation input to the operation unit 2. The input device 1 is provided in, for example, a vehicle 4 (see FIG. 2) and is used when operating an in-vehicle device such as an in-vehicle air conditioner, an audio device, a navigation system, and a mirror device. The input device 1 of this example operates an in-vehicle device based on the input of the user interface type switch unit 5. The user interface is preferably, for example, a graphical user interface.

The vehicle 4 is equipped with a sound generating unit 6 that outputs a sound to the user when the operating unit 2 is operated. The sound generating unit 6 is connected to the control device 3, and its operation is controlled by the control device 3.

The operation unit 2 of the present embodiment is a touch pad that selects and designates, for example, the display body 11 as the switch unit 5 displayed on the display unit 10 through a touch operation on the touch surface. The display unit 10 is, for example, a display of a navigation system. The display body 11 is a display button displayed on the display unit 10 and selected and designated by the operation of the operation unit 2. A plurality of display bodies 11 are displayed on the display unit 10 according to various functions of the vehicle-mounted device. Further, when the display body 11 is selected and specified via the operation unit 2, it is preferable to perform visual feedback notifying that the selection is specified, for example, displaying an animation in which a button is pressed.

The control device 3 includes a monitoring unit 12 that monitors the operation of the display body 11. The monitoring unit 12 of the present embodiment recognizes which display body 11 is selected based on the input from the operation unit 2. As a result, the control device 3 causes the user to execute the operation of the in-vehicle device according to the function item corresponding to the display body 11 selected and designated.

The control device 3 includes an output processing unit 13 that outputs an operation reaction sound when the monitoring unit 12 recognizes that the display body 11 has been operated. The operation reaction sound notifies the user that the display body 11 has been operated. That is, the output processing unit 13 provides auditory feedback to the user by the operation reaction sound. In the case of the present embodiment, the output processing unit 13 outputs an operation reaction sound when the display body 11 is selected and designated by the operation of the operation unit 2.

As shown in FIG. 2, the sound generating unit 6 is arranged in the vicinity of the operating unit 2. Here, the vicinity of the operation unit 2 refers to a range A in which the user in the vehicle 4 can perceive that the sound from the sound generation unit 6 is heard from the operation unit 2. Note that FIG. 2 schematically shows the range A. The actual range A is appropriately changed, for example, through an experiment.

As shown in FIG. 1, the control device 3 includes a display setting unit 21 for setting the design of the display body 11. The display setting unit 21 sets the display designated by the user's manual operation as the design of the display body 11. The display of the display body 11 is, for example, a texture that imitates the appearance of a physical material. The display setting unit 21 sets the design of the display body 11 to one selected by the user from a plurality of types of textures registered in advance. The plurality of types of textures include, for example, metal textures, wood textures, and rubber textures. The image data of these textures is stored in the memory 23 as a storage unit of the control device 3. The display setting unit 21 of the present embodiment uniformly sets the textures of the plurality of display bodies 11.

The control device 3 includes a sound setting unit 22 that sets an operation reaction sound emitted from the sound generation unit 6 when the display body 11 is operated. The sound setting unit 22 is a sound that matches the impression of the design of the display body 11, that is, a sound that expresses the visual impression of the display body 11, when, for example, the display body 11 is selected by the operation of the operation unit 2. Set the operation reaction sound so as to generate. The sound setting unit 22 sets the sound data corresponding to the texture currently set on the display body 11 as the operation reaction sound from the plurality of types of sound data stored in advance. Then, when the display body 11 is selected, the control device 3 generates a set operation reaction sound as auditory feedback. A plurality of types of sound data corresponding to a plurality of types of textures are stored in the memory 23.

FIG. 3 shows the waveforms of sound pressure with respect to the frequencies of the basic sound data D, the metal sound data D1, the wood sound data D2, and the rubber material sound data D3 as a plurality of types of sound data. The metal sound data D1, the wood sound data D2, and the rubber material sound data D3 are generated by setting the sound pressure according to the sound frequency with respect to the basic sound data D. The metal sound data D1, the wood sound data D2, and the rubber material sound data D3 correspond to the metal texture, the wood texture, and the rubber material texture, respectively.

The sound data D1, D2, and D3 are generated by setting the sound pressure according to the frequency with respect to the basic sound data. Further, the sound data D1, D2, and D3 are generated so that the impression of each sound matches the impression of the corresponding texture. For example, the metal sound data D1 is set by raising the sound pressure in the high frequency band with respect to the sound data D so as to give a high and sharp impression. Further, the sound data D2 of wood raises the sound pressure in the midrange frequency band between the treble range and the low range with respect to the sound data D so as to give a slightly low and dull impression, and the sound pressure in the high range frequency band. It is set with the sound pressure lowered. Further, in the sound data D3 of the rubber material, the sound pressure in the low frequency band is increased and the sound pressure in the other frequency bands is decreased with respect to the sound data D so as to give a low and soft impression. ..

Hereinafter, the setting of the operation reaction sound will be described as the operation of the present embodiment.
As shown in FIG. 4, in S101 (S is an abbreviation for a step, the same applies hereinafter), the display setting unit 21 of the control device 3 sets the texture of the display body 11 by a manual operation of the user. The display setting unit 21 sets the texture selected by the user among the plurality of types of textures stored in the memory 23 as the texture of the display body 11.

In S102, the sound setting unit 22 of the control device 3 sets the sound data corresponding to the texture set by the display setting unit 21 as the operation reaction sound. The sound setting unit 22 selects the sound data corresponding to the texture from the plurality of types of sound data stored in the memory 23, and sets this as the operation reaction sound.

When the monitoring unit 12 recognizes the operation of the display body 11, the output processing unit 13 of the control device 3 outputs the operation reaction sound set by the sound setting unit 22 from the sound generation unit 6. When the display body 11 is selected by the operation of the operation unit 2, the output processing unit 13 generates an operation reaction sound corresponding to the selected display body 11 from the sound generation unit 6. As a result, when the display body 11 is selected, a sound expressing the visual impression of the display body 11 can be generated as an operation reaction sound.

By the way, conventionally, in the touch operation of the operation unit 2, there is a problem that it is difficult to recognize the feeling of performing the operation, that is, the operation feeling. On the other hand, in the case of the present embodiment, the operation feeling is easily recognized by providing auditory feedback to the operation input.

Here, there is a cross-modal perceptual effect in which other sensations are complemented when the stimuli of two or more sensations of a person are consistent. In auditory feedback, it was expected that the user could feel as if he / she had manipulated a real material by matching the visual sense with the auditory sense to generate a cross-modal perceptual effect.

In the case of the present embodiment, the sound setting unit 22 sets the sound data corresponding to the texture set in the design of the display body 11 as the operation reaction sound. Therefore, the control device 3 can make the user feel as if he / she has operated the real material by listening to the operation reaction sound of the impression that matches the visual impression of the display body 11. As a result, it is possible to give the user not only the feeling of operating the display body 11 but also a feeling of luxury and an uplifting feeling obtained from the texture of the material, for example. Therefore, the operation feeling can be improved as compared with the case where an operation reaction sound, for example, a beep sound, which has little relation to or has nothing to do with the visual impression of the display body 11, is emitted.

Further, in the case of the present embodiment, the sound generating unit 6 is arranged in the vicinity of the operating unit 2. Therefore, when the user operates the operation unit 2, it becomes easy to perceive through the operation reaction sound whether or not the selection can be completed according to the operation intention. Further, if the sound generating unit 6 is arranged in the vicinity of the display unit 10, the visual stimulus and the auditory stimulus can be easily matched.

Hereinafter, the effects of this embodiment will be described.

According to this configuration, the design of the display body 11 can be set according to the user's preference. Further, the operation reaction sound can be set as a sound expressing the design of the display body 11.

(4) The sound generation unit 6 is arranged in the vicinity of the operation unit 2 used when the display body 11 is selected and designated. According to this configuration, by arranging the sound generating unit 6 in the vicinity of the operating unit 2, it is possible to preferably perform auditory feedback.

(5) The sound setting unit 22 expresses a plurality of types of sound data D1, D2, and D3 by setting the sound pressure according to the frequency of the sound with respect to the basic sound data D.
