Embodiments for Carrying Out the Invention

[0009] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. [1. First Embodiment] [1-1. Configuration] The environmental management system 1 shown in FIGS. 1 and 2 is mounted on a vehicle as an example. The environmental management system 1 includes a first vibration device 2a, a second vibration device 2b, a third vibration device 2c, a first sound device 3a, a second sound device 3b, a control unit 4, a monitor 5, and a seat 6. Hereinafter, the first vibration device 2a, the second vibration device 2b, and the third vibration device 2c may be collectively referred to as the vibration device 2. Also, the first sound device 3a and the second sound device 3b may be collectively referred to as the sound device 3. The environmental management system 1 can control the vibration device 2 and the sound device 3, and induces the occupant 10 into one of a plurality of states by executing a vibration operation by the vibration device 2 when sound is output from the sound device 3. Hereinafter, sound refers to an audible sound output from the sound device 3, and music refers to the artistic part of the sound.

[0010] The vibration device 2 is a device for applying a vibration stimulus to the occupant 10. The vibration device 2 vibrates in accordance with a vibration waveform set by the control unit 4. The first vibration device 2a is embedded at a position near the back of the occupant 10 in contact with the backrest of the seat 6 so as to be able to apply a vibration stimulus.

[0011] The second vibration device 2b is embedded at a position in the backrest of the seat 6 where it can contact near the waist of the occupant 10 and apply a vibration stimulus. The third vibration device 2c is embedded at a position on the seat surface of the seat 6 where it can contact near the back of the occupant 10's thighs and apply a vibration stimulus.

[0012] The audio device 3 is a speaker for playing sound. The audio device 3 outputs the sound set by the control unit 4. The first audio device 3a is installed near the ear of the occupant 10 on the seat 6.

[0013] The second audio device 3b is installed near the navigation device. The second audio device 3b is provided at a position farther from the position of the ear of the occupant 10 at the time of seating than the first audio device 3a. The control unit 4 is mainly composed of a well-known microcomputer having a CPU, ROM, RAM, flash memory, etc. The CPU executes a program stored in the ROM which is a non-transitory tangible recording medium. When the program is executed, the method corresponding to the program is executed. Specifically, the control unit 4 executes the mode process shown in FIG. 7 described later according to the program. Note that the control unit 4 may include one microcomputer or a plurality of microcomputers.

[0014] The method for realizing the functions of each part included in the control unit 4 is not limited to software, and a part or all of the functions may be realized using one or a plurality of hardware. For example, when the above functions are realized by an electronic circuit which is hardware, the electronic circuit may be realized by a digital circuit, an analog circuit, or a combination thereof.

[0015] The control unit 4 is configured to output voice to at least one acoustic device 3 and execute a vibration operation on at least one vibration device 2 in a combination corresponding to a state mode described later among combinations of at least one acoustic device 3 out of the plurality of acoustic devices 3 and at least one vibration device 2 out of the plurality of vibration devices 2.

[0016] The control unit 4 includes a music generation device 41 and a vibration generation device 42. The music generation device 41 acquires music data stored in a storage medium such as a flash memory, a CD (Compact Disc), or the cloud, and generates a voice signal of the music from the acquired data. The music generation device 41 outputs the generated voice signal to the acoustic device 3. At this time, the music generation device 41 outputs the voice signal to the acoustic device 3 corresponding to the state mode. More specifically, the music generation device 41 can be selectively connected to a terminal 6a connected to the first acoustic device 3a or a terminal 6b connected to the second acoustic device 3b. Note that the music generation device 41 may be connectable to the terminal 6a and the terminal 6b simultaneously.

[0017] The control unit 4 outputs a vibration signal to the vibration device 2 corresponding to the state mode. The control unit 4 can output the voice signal output from the music generation device 41 to the vibration device 2 as a vibration signal, or can output the vibration signal set by the vibration generation device 42 to the vibration device 2.

[0018] The audio signal output from the music generation device 41 passes through the low-pass filter 43, and only the low-frequency component is output to the vibration device 2 as a vibration signal. For example, the cut-off frequency of the low-pass filter 43 is set to near the lower limit of the audible frequency or a frequency lower than that. In this embodiment, the cut-off frequency of the low-pass filter 43 is set between 20 Hz and 40 Hz. By connecting any one or more of the terminal 6c connected to the first vibration device 2a, the terminal 6d connected to the second vibration device 2b, and the terminal 6e connected to the third vibration device 2c to the terminal 7a, the vibration signal in the low-frequency band that has passed through the low-pass filter 43 is output to the vibration device 2. Note that the control unit 4 may include a band-pass filter instead of the low-pass filter 43.

[0019] The vibration generation device 42 sets a vibration waveform and outputs a vibration signal corresponding to the vibration waveform to the vibration device 2. For example, the vibration generation device 42 sets the frequency, period, intensity of the vibration, and the time for applying the vibration stimulus, etc. By connecting any one or more of the terminal 6c connected to the first vibration device 2a, the terminal 6d connected to the second vibration device 2b, and the terminal 6e connected to the third vibration device 2c to the terminal 7b, the set vibration signal is output to the vibration device 2.

[0020] The monitor 5 is a display device for presenting the state mode to the occupant 10. For example, the monitor 5 is provided with a touch panel, and the occupant 10 touches the icon of the desired state mode from the displayed state mode icons. A signal indicating the state mode of the icon touched by the occupant 10 is input to the control unit 4. Also, when the fatigue reduction mode described later is selected among the state modes, icons indicating the fatigue positions are displayed so that the fatigue positions where the fatigue reduction mode is to be executed can be selected. In this embodiment, icons indicating the back, waist, and back of the thigh are displayed as the icons indicating the fatigue positions. A signal of the icon indicating the fatigue position touched by the occupant 10 is input to the control unit 4.

[0021] [1-2. Explanation of the state mode] Using FIG. 3, each state mode will be described. The solid line represents the vibration waveform of the vibration device 2 or the voice waveform of the acoustic device 3, and the dotted line represents the envelope of the voice of the acoustic device 3.

[0022] First, the concentration mode will be described. The concentration mode refers to a mode in which the comfort and arousal level of the occupant 10 are moderately increased, and an effect of enhancing the concentration of the occupant 10 can be expected. In the concentration mode, the control unit 4 causes the first acoustic device 3a to output voice and causes the first vibration device 2a to execute a vibration operation. Specifically, the control unit 4 causes the first vibration device 2a to execute a vibration operation so that the shape of the envelope of the vibration waveform in the vibration operation executed by the first vibration device 2a matches the shape of the envelope of a specific voice among the voices output from the first acoustic device 3a. The specific voice refers to the voice in the low-frequency band that has passed through the low-pass filter 43. For example, the bass voice that beats the tempo of the music corresponds to the specific voice. Also, the fact that the shapes of the envelopes match includes both completely matching and substantially matching. As an example of the concentration mode, the control unit 4 outputs music with a fast tempo as the voice and outputs a vibration stimulus linked to the music. Music with a fast tempo is, for example, music with a tempo faster than the heart rate of a human at rest. As an example, it refers to music with a tempo of about 140 bpm for a specific voice.

[0023] Next, the relaxation mode will be described. The relaxation mode is a mode that can be expected to have an effect of promoting relaxation of the occupant 10 by increasing the comfort of the occupant 10 and decreasing the wakefulness. Note that when the relaxation mode is maintained for a long time, an effect of putting the occupant 10 to sleep can also be expected. In the relaxation mode, the control unit 4 causes the first acoustic device 3a to output sound and causes the first vibration device 2a to execute a vibration operation. Specifically, the control unit 4 controls the first vibration device 2a to intermittently execute a vibration operation such that the shape of the envelope of the vibration waveform in the vibration operation executed by the first vibration device 2a does not match the shape of the envelope of a specific sound among the sounds output from the first acoustic device 3a, and the amplitude of the vibration waveform in the vibration operation executed by the first vibration device 2a is smaller than that in other modes. As an example of the relaxation mode, the control unit 4 outputs a vibration stimulus having a frequency that is easily felt by the skin of the occupant 10. The frequency that is easily felt by the skin refers to a frequency at which vibration is easily felt by the receptors of the skin and at which no noise is generated from the vibration device 2. As an example, a frequency of 40 Hz or 30 Hz or less is preferable, and a frequency of 20 Hz or less is more preferable. Further, for example, the control unit 4 outputs music with a slow tempo as sound and outputs a vibration stimulus with a tempo even slower than that of the music. Music with a slow tempo is, for example, music with a tempo slower than the heart rate of a human at rest. As an example, it refers to music with a tempo of about 65 bpm for a specific sound. The vibration stimulus with a tempo even slower than that of the music is, for example, a vibration stimulus with a tempo of about 30 bpm. Note that in the relaxation mode, the control unit 4 may cause the second acoustic device 3b to output sound.

[0024] Next, the fatigue reduction mode will be described. The fatigue reduction mode refers to a mode in which an effect of reducing the fatigue feeling of the occupant 10 can be expected. In the fatigue reduction mode, the control unit 4 causes the second sound device 3b to output sound, and causes the vibration device 2 at the fatigue position designated by the occupant 10 to execute a vibration operation. In the present embodiment, the first vibration device 2a and the second vibration device 2b are caused to execute a vibration operation. Specifically, the control unit 4 causes the first vibration device 2a and the second vibration device 2b to execute a vibration operation so that the shape of the envelope of the vibration waveform in the vibration operation executed by the first vibration device 2a and the second vibration device 2b does not match the shape of the envelope of a specific sound among the sounds output from the second sound device 3b. As an example of the fatigue reduction mode, the control unit 4 outputs a vibration stimulus at a frequency that is not linked to music and is easily felt by the skin of the occupant 10. In the fatigue reduction mode, the control unit 4 may cause the first sound device 3a to output sound, or may not cause any of the sound devices 3 to output sound. Further, if the vibration stimulus is continuously output, the occupant 10 may get used to the vibration stimulus and it may become difficult to feel the vibration stimulus. Therefore, the vibration stimulus may be intermittently performed.

[0025] Next, the awakening mode will be described. The awakening mode refers to a mode in which an effect that the occupant 10 can instantaneously wake up from a sleeping state can be expected. In the awakening mode, the control unit 4 causes the first sound device 3a to output sound, and causes the third vibration device 2c to execute a vibration operation. Specifically, the control unit 4 intermittently causes the third vibration device 2c to execute a vibration operation so that the shape of the envelope of the vibration waveform in the vibration operation executed by the third vibration device 2c does not match the shape of the envelope of a specific sound among the sounds output from the first sound device 3a. The sound output from the first sound device 3a is preferably an alarm sound. The alarm sound is a sound with a relatively high frequency that the occupant 10 feels is noisy, for example, a sound of about 2000 Hz. As an example of the awakening mode, the control unit 4 outputs an alarm sound and a vibration stimulus at a frequency that is easily felt by the skin of the occupant 10.

[0026] [1-3. Sensory evaluation] [1-3-1. Experiment to confirm the effect of the concentration mode] Six subjects were tested for their ability to track a sine-wave curve moving across a screen using a mouse. The sine-wave curve had a certain width, and the amount of deviation of the mouse operation from the center line was recorded.

[0027] Figure 4 shows a graph plotting the amount of deviation of mouse operation in (i) the case where neither music nor vibration stimulation was given and (ii) the case where music and vibration stimulation in the focused mode were given. In the pattern (i) described above, the average value of the amount of deviation of mouse operation among the six subjects was 12.1%. On the other hand, in the pattern (ii), the average value of the amount of deviation of mouse operation among the six subjects was 10.5%. When taking the average value of the amount of deviation of mouse operation in the pattern (i) as a reference, the average value of the amount of deviation of mouse operation in the pattern (ii) decreased by approximately 13.5%.

[0028] [1-3-2. Experiment to confirm the effect of the relaxation mode] An experiment to confirm the effect of the relaxation mode was conducted on six subjects. Figure 5 shows a graph plotting the time until falling asleep in (iii) the case where neither music nor vibration stimulation was given and (iv) the case where music and vibration stimulation in the relaxation mode were given. In this experiment, in a darkened room, the subjects' faces were photographed, and it was determined that they had fallen asleep when the state of closing their eyes continued for a certain period of time.

[0029] In the pattern (iii) described above, the average value of the time until falling asleep among the six subjects was 20 minutes. On the other hand, in the pattern (iv), the average value of the time until falling asleep among the six subjects was 15 minutes. When taking the average value of the time until falling asleep in the pattern (iii) as a reference, the average value of the time until falling asleep in the pattern (iv) decreased by 25%.

[0030] [1-3-3. Experiment to confirm the effect of the fatigue reduction mode] An experiment was conducted on 7 subjects to confirm the effect of the fatigue reduction mode. This experiment was carried out while having the 7 subjects operate a driving simulator. Specifically, after having the subjects continuously use the driving simulator for 50 minutes, vibration stimulation was applied to the part with higher fatigue degree between the shoulder and the waist. Four subjects answered that the shoulder had a higher fatigue degree, and three subjects answered that the waist had a higher fatigue degree. The fatigue degree was indicated in 6 levels from 0 to 5, and the subjects were verbally surveyed and asked to answer every 2 minutes. The vibration stimulation was set at a frequency of 30 Hz, a period of 1.5 Hz, and a duty ratio of 90%, and was applied for 15 minutes. As shown in Figure 6A, the fatigue degree of the shoulder was reduced after the vibration stimulation compared to immediately before the vibration stimulation. Also, as shown in Figure 6B, the fatigue degree of the waist was reduced after the vibration stimulation compared to immediately before the vibration stimulation.

[0031] [1-4. Processing] The mode processing executed by the control unit 4 will be described using the flowchart shown in Figure 7. Note that this processing is executed when the occupant 10 touches any of the icons of the status modes displayed on the monitor 5.

[0032] First, in S101, the control unit 4 acquires the status mode and sets one of the status modes. Specifically, the control unit 4 acquires the status mode input from the monitor 5, determines whether the status mode is any of the concentration mode, relaxation mode, fatigue reduction mode, and arousal mode, and sets the status mode according to the determination. When the fatigue reduction mode is set, the fatigue position input from the monitor 5 is also acquired to identify the fatigue position of the occupant 10. Note that S101 corresponds to the setting unit and the identification unit.

[0033] When the control unit 4 determines in S101 that the status mode is the concentration mode, it proceeds to S102. In S102, the control unit 4 outputs the sound and vibration stimulation in the above-described concentration mode. Then, the control unit 4 ends the mode processing.

[0034] When the control unit 4 determines in S101 that the state mode is the relaxation mode, it proceeds to S103. In S103, the control unit 4 outputs the voice and vibration stimulation in the relaxation mode described above. Then, the control unit 4 ends the mode process.

[0035] When the control unit 4 determines in S101 that the state mode is the fatigue reduction mode, it proceeds to S104. In S104, the control unit 4 outputs the voice and vibration stimulation in the fatigue reduction mode described above. Then, the control unit 4 ends the mode process.

[0036] When the control unit 4 determines in S101 that the state mode is the arousal mode, it proceeds to S105. In S105, the control unit 4 outputs the voice and vibration stimulation in the arousal mode described above. Then, the control unit 4 ends the mode process. Note that S102 to S105 correspond to the control unit.

[0037] [1-5. Effects] According to the embodiment described in detail above, the following effects can be obtained. (1a) The control unit 4 is configured to output voice to at least one acoustic device 3 and execute a vibration operation on at least one vibration device 2 in a combination according to the state mode. According to such a configuration, effective influence can be exerted in many scenarios by various voices and vibration stimulations.

[0038] (1b) In the concentration mode, the control unit 4 causes the first vibration device 2a to execute a vibration operation such that the shape of the envelope of the vibration waveform in the vibration operation executed by the first vibration device 2a matches the shape of the envelope of a specific voice among the voices output from the first acoustic device 3a. According to such a configuration, as described above in [1-3-1. Experiment to confirm the effect of the concentration mode], it is possible to improve the performance of the work of the occupant 10, and an effect of enhancing the concentration of the occupant 10 can be expected. In addition, since voice is output from the first acoustic device 3a installed near the ear of the occupant 10, an effect of enhancing the sense of presence and comfort can be expected, and it is possible to suppress sound leakage to the surroundings even at a high volume.

[0039] (1c) In the relaxation mode, the control unit 4 intermittently causes the first vibration device 2a to execute a vibration operation so that the shape of the envelope of the vibration waveform in the vibration operation executed by the first vibration device 2a does not match the shape of the envelope of a specific voice among the voices output from the first sound device 3a, and so that the amplitude of the vibration waveform in the vibration operation executed by the first vibration device 2a is smaller than that in other modes. According to such a configuration, as described above in [1-3-2. Experiment for confirming the effect of the relaxation mode], an effect of prompting the occupant 10 to relax can be expected. Further, by making the amplitude of the vibration waveform smaller than that in other modes, it is possible to avoid a state in which the vibration stimulus is too strong and the relaxation effect is weakened.

[0040] (1d) In the fatigue reduction mode, the control unit 4 causes the first vibration device 2a and the second vibration device 2b to execute a vibration operation so that the shape of the envelope of the vibration waveform in the vibration operation executed by the first vibration device 2a and the second vibration device 2b does not match the shape of the envelope of a specific voice among the voices output from the second sound device 3b. According to such a configuration, as described above in [1-3-3. Experiment for confirming the effect of the fatigue reduction mode], it becomes possible to apply a vibration stimulus to the fatigue position, and an effect of reducing the sense of fatigue can be expected.

[0041] (1e) In the arousal mode, the control unit 4 intermittently causes the third vibration device 2c to execute a vibration operation so that the shape of the envelope of the vibration waveform in the vibration operation executed by the third vibration device 2c does not match the shape of the envelope of a specific voice among the voices output from the first sound device 3a. According to such a configuration, an effect of instantaneously arousing the occupant 10 can be expected. Further, since an alarm sound is output from the first sound device 3a installed near the occupant 10's ear, it is easier to arouse the occupant 10.

[0042] (1f) The audio signal output from the music generator 41 passes through the low-pass filter 43 and is output to the vibration device 2 as a vibration signal with only low-frequency components. The cut-off frequency of the low-pass filter 43 is set to a frequency near the lower limit of the audible frequency or a frequency lower than that. According to such a configuration, even if the vibration of the vibration device 2 is heard by the occupant 10 as sound, it is not recognized as noise, so it is possible to suppress the inhibition of the comfort of the occupant 10.

[0043] (1g) The control unit 4 outputs a vibration stimulus at a frequency that is easily felt by the skin of the occupant 10 in each state mode. According to such a configuration, although the vibration is easily felt by the receptors of the skin, it is difficult for noise to be generated from the vibration device 2, so the state of the occupant 10 can be more effectively transitioned.

[0044] [1-6. Corresponding relationship] The first vibration device 2a corresponds to the back vibration device, the first vibration device 2a, the second vibration device 2b, and the third vibration device 2c correspond to the specific vibration devices, the third vibration device 2c corresponds to the seat surface vibration device, the control unit 4 corresponds to the control device, and the environment management system 1 corresponds to the control system. Also, the monitor 5 corresponds to the selection device, and the seat 6 corresponds to the seating part.

[0045] [2. Other embodiments] As described above, the embodiments of the present disclosure have been described. Needless to say, the present disclosure is not limited to the above embodiments and can take various forms.

[0046] (2a) In the above embodiment, a configuration in which the three vibration devices 2, i.e., the first vibration device 2a, the second vibration device 2b, and the third vibration device 2c, are caused to vibrate has been exemplified. However, in each of the above-described modes, vibration may be executed on two or fewer vibration devices, or four or more vibration devices. Also, in the above embodiment, a configuration in which music is output to the two acoustic devices 3, i.e., the first acoustic device 3a and the second acoustic device 3b, has been exemplified. However, in each of the above-described modes, a configuration in which music is output to three or more acoustic devices may also be used.

[0047] (2b) In the above embodiment, an example is given of a configuration in which the occupant 10 touches an icon of a desired vibration mode from among the state mode icons displayed on the monitor 5, and the desired state mode is executed. However, the timing at which the execution of the state mode is started is not limited to this. For example, when the control unit 4 determines that the occupant 10 is feeling sleepy, the control unit 4 may cause the vibration device 2 to execute the awakening mode. As an example, the control unit 4 may analyze an image of the face of the occupant 10 taken by the driver status monitor to determine whether the occupant 10 is feeling sleepy. In this way, the vibration operation may be started using the state of the occupant 10 as a trigger. In addition to this, other factors such as the brightness, temperature, environment in which the vehicle is present such as road attributes, time, distance or time to the destination obtained by the navigation system, etc. may also be used as triggers.

[0048] (2c) In the sensory evaluation of the above embodiment, the relationship between music and vibration stimulation was described in detail. However, instead of music, non-music voices may be played, and the state of the occupant 10 may be induced by a combination of the voices and vibration stimulation.

[0049] (2d) In the above embodiment, an example is given of a configuration in which the environment management system 1 is mounted on a vehicle. However, the object on which the environment management system 1 is mounted is not limited to this. For example, the environment management system 1 may be mounted on a moving body other than an automobile, such as a railway vehicle, an aircraft, or a ship. Also, for example, the environment management system 1 may be mounted on a non-moving body component used indoors, such as an office chair.

[0050] (2e) In the above embodiment, an example is given of a configuration in which the occupant 10 selects an icon indicating the fatigue position, and the fatigue reduction mode is executed for the selected part. However, the fatigue position does not have to be selected. For example, the fatigue reduction mode may be executed by sequentially switching the vibrating vibration devices 2. According to such a configuration, the fatigue of the whole body can be evenly reduced.

[0051] (2f) In the wake-up mode of the above-described embodiment, a configuration in which voice is output to the first audio device 3a has been exemplified. However, using a plurality of audio devices 3, voice may be output so that the sound source moves from relatively far away to relatively close. According to such a configuration, the movement of the sound source can produce a greater sense of urgency.

[0052] (2g) The functions of one component in the above-described embodiment may be distributed among a plurality of components, or the functions of a plurality of components may be integrated into one component. Also, a part of the configuration of the above-described embodiment may be omitted. Further, at least a part of the configuration of the above-described embodiment may be added to, replaced with, etc., the configuration of another of the above-described embodiments.

[0053] (2h) The present disclosure can be realized in various forms, such as, in addition to the control device described above, a system including the control device as a component, a program for causing a computer to function as the control device, a medium recording this program, a method of vibration control, and the like.
