And a plate-like portion supported by an external structure connected to the stretchable film in a state where bending stress is generated from the stretchable film. In this configuration, the stretchable film has elasticity in the normal direction of the main surface, and since the contacted part is provided on the stretchable film, the contacted part is actually pushed in by the user's finger or the like. It is possible to give the user a feeling of pushing the contacted portion. In addition, when the plate-like portion vibrates in the thickness direction due to the vibration of the stretch film in the in-plane direction, the plate-like portion is supported by the external structure, so not only the plate-like portion but also the stretch film has a main surface normal. Directional vibration is caused. Then, the contacted part works as a weight against the vibration in the main surface normal direction of the stretchable film, so that this amplifies the vibration in the main surface normal direction of the stretchable film so that the contacted part is Can be vibrated greatly in the normal direction of the main surface of the stretchable film. At this time, the contacted part generally vibrates in the normal direction of the main surface of the stretchable film, so that variation in vibration amount at each position of the contacted part can be reduced. Therefore, it is said that when a user's finger or the like comes into contact with the contacted portion, a large tactile feedback can be reliably transmitted to the user.

(本発明の実施の形態に係る触覚呈示装置1の動作)
以下、図3に示すフローチャートのステップに従って触覚呈示装置1の動作を説明する。
(Operation of the tactile sense presentation device 1 according to the embodiment of the present invention)
Hereinafter, the operation of the tactile sense presentation device 1 will be described according to the steps of the flowchart shown in FIG.
触覚呈示装置1の動作がスタートすると、制御部30は振動発生部10に振動駆動信号Svを出力して振動を発生させる。これにより、ステアリング12を振動させて乗員90に振動呈示を行なう(Step1)。 When the operation of the tactile sense presentation device 1 starts, the control unit 30 outputs a vibration drive signal Sv to the vibration generation unit 10 to generate vibration. Thereby, the steering 12 is vibrated to present the vibration to the occupant 90 (Step 1).
制御部30は、生体情報検出部20により生体情報信号Shを取得する(Step2)。この生体情報信号Shは、心拍数である。 The control unit 30 acquires the biological information signal Sh by the biological information detection unit 20 (Step 2). This biological information signal Sh is a heart rate.
制御部30は、生体情報信号Shが閾値Sth以上かどうかを判断する(Step3)。閾値Sthは、例えば、乗員90の心拍数が運転に適した所定の心拍数に設定されている。この閾値Sth(心拍数)は、任意に設定することが可能である。 The control unit 30 determines whether or not the biological information signal Sh is greater than or equal to the threshold value Sth (Step 3). The threshold value Sth is set to a predetermined heart rate suitable for driving, for example, the heart rate of the occupant 90. This threshold value Sth (heart rate) can be set arbitrarily.
制御部30は、生体情報信号Shが閾値Sth以上の場合はStep4に進み(Step3:Yes)、生体情報信号Shが閾値Sth未満の場合はStep5に進む(Step3:No)。 When the biological information signal Sh is equal to or greater than the threshold value Sth, the control unit 30 proceeds to Step 4 (Step 3: Yes), and proceeds to Step 5 when the biological information signal Sh is less than the threshold value Sth (Step 3: No).
制御部30は、振動強度を弱める(Step4)。すなわち、制御部30は、振動駆動信号Svを小さくして振動発生部10の発生する振動強度を弱める。これにより、乗員90の緊張度が高い場合に振動強度を弱めることができる。 The control unit 30 weakens the vibration intensity (Step 4). That is, the control unit 30 decreases the vibration drive signal Sv and weakens the vibration intensity generated by the vibration generation unit 10. Thereby, when the tension | tensile_strength of the passenger | crew 90 is high, a vibration intensity | strength can be weakened.
また、制御部30は、振動強度を強める(Step5)。すなわち、制御部30は、振動駆動信号Svを大きくして振動発生部10の発生する振動強度を強める。これにより、乗員90の緊張度が低い、あるいは、反応がない場合に振動強度を強めることができる。 Further, the control unit 30 increases the vibration intensity (Step 5). That is, the control unit 30 increases the vibration drive signal Sv to increase the vibration intensity generated by the vibration generation unit 10. As a result, the vibration intensity can be increased when the occupant 90 has low tension or no response.
本実施の形態に係る触覚呈示装置1は、上記の一連のフローを実施することにより、生体情報検出手段の検出結果が規定範囲内となるように、振動発生部10の発生する振動強度を制御することができる。上記に説明したようなStep1からStep5のフィードバック制御により、乗員90の生体情報信号Shが閾値Sthに収束して規定範囲内となるような制御が実行される。すなわち、制御部30は、生体情報検出手段での検出結果が規定範囲を上回っている場合、触覚呈示手段による乗員90への呈示強度を小さくする。また、制御部30は、生体情報検出手段での検出結果が規定範囲を下回っている場合、触覚呈示手段による乗員90への呈示強度を大きくする。これにより、乗員90の緊張度が適度となるように、振動発生部10の発生する振動強度を制御して、触覚呈示をすることができる。 The tactile sensation presentation apparatus 1 according to the present embodiment controls the vibration intensity generated by the vibration generator 10 so that the detection result of the biological information detection means is within the specified range by performing the above-described series of flows. can do. By the feedback control from Step 1 to Step 5 as described above, control is performed so that the biological information signal Sh of the occupant 90 converges to the threshold value Sth and falls within the specified range. In other words, the control unit 30 reduces the strength of presentation to the occupant 90 by the tactile sense presenting means when the detection result by the biological information detecting means exceeds the specified range. Moreover, the control part 30 enlarges the presentation intensity | strength to the passenger | crew 90 by a tactile sense presentation means, when the detection result in a biometric information detection means is less than the regulation range. Thereby, tactile sensation can be presented by controlling the vibration intensity generated by the vibration generating unit 10 so that the degree of tension of the occupant 90 is appropriate.
したがって、生体情報から乗員の緊張度を推定し学習することで、その乗員にとって適切な触覚呈示強度を提供することが可能となる。 Therefore, by estimating and learning the occupant's tension level from the biometric information, it is possible to provide an appropriate tactile sensation intensity for the occupant.
図4に示すように、振動発生部10から振動が入力され、制御量である振動呈示が生体情報検出部20を介してフィードバックされる。生体情報検出部20の出力である生体情報信号Shはフィードバック係数Kにより、フィードバックされる。制御部30は、振動発生部10の信号Svと生体情報検出部20からのフィードバック信号K・Svとの差分が規定範囲内へと収束するように振動呈示を行なう。 As shown in FIG. 4, vibration is input from the vibration generating unit 10, and a vibration presentation as a control amount is fed back via the biological information detection unit 20. The biological information signal Sh that is an output of the biological information detection unit 20 is fed back by a feedback coefficient K. The control unit 30 presents the vibration so that the difference between the signal Sv of the vibration generating unit 10 and the feedback signal K · Sv from the biological information detecting unit 20 converges within a specified range.
このような生体情報に基づくフィードバック制御により、乗員の緊張度に対して、適切な触覚呈示強度を提供することが可能となる。 Feedback control based on such biological information makes it possible to provide an appropriate tactile sensation presentation strength with respect to the occupant's tension.
信号Svに基づく呈示振幅をA1とし、図5Aに示すように、時間t1からt3まで振動発生部10を駆動して振動呈示を行なう。制御部30は、図4に示したフィードバック制御により、図5Bに示すように、時間t1からt2までの過渡期間を経て、時間t2からt3まで期間において、乗員の緊張度に対して適切な呈示振幅A2で振動呈示を行なうことができる。 A presenting amplitude based on the signal Sv is A1, and as shown in FIG. 5A, the vibration generating unit 10 is driven from time t1 to time t3 to perform vibration presenting. As shown in FIG. 5B, the control unit 30 presents an appropriate presentation for the occupant's tension in the period from time t2 to t3 through the transition period from time t1 to t2, as shown in FIG. 5B, by the feedback control shown in FIG. The vibration can be presented with the amplitude A2.
本発明の実施の形態に係る触覚呈示装置の動作は、図3で示したような離散的なフィードバック制御が可能であり、また、図4、図5A、図5Bで示したような連続的なフィードバック制御も可能である。 The operation of the tactile sensation presentation apparatus according to the embodiment of the present invention is capable of discrete feedback control as shown in FIG. 3, and continuous as shown in FIGS. 4, 5A, and 5B. Feedback control is also possible.
また、図5A、Bで示したような連続的な振動波形ではなく、時系列的に離散化した振動波形列に対してもフィードバック制御が可能である。 Further, feedback control can be performed not on the continuous vibration waveform as shown in FIGS. 5A and 5B but also on the vibration waveform sequence discretized in time series.
