(Specific examples of facial expressions according to the degree of prompting)
The display of a facial expression according to the degree of prompting the user to act according to the output value from the sensor unit 60 will be described using a specific example.

  Below, the case where the sensor part 60 detects temperature is demonstrated. When the output value from the sensor unit 60 is a high temperature outside a predetermined range set for the temperature, the degree setting unit 12 sets the degree of prompting the user to perform the cooling operation of the air conditioner according to the output value. . The degree setting unit 12 sets the degree to which the predetermined range set for the temperature is less than 28 ° C. and the output value from the sensor unit 60 is 28 ° C. or more and less than 30 ° C. as “small”. The degree of prompting is set as “medium”. Thus, first, the degree setting unit 12 sets the degree of prompting the user to take an action according to the output value from the sensor unit 60 based on the output value from the sensor unit 60.

  In accordance with the setting of the degree setting unit 12, the display control unit 11, when the degree of prompting is small, is slightly a little sweat with a little sweat shown in FIG. A facial image with a facial expression that turns red is displayed. At this time, the utterance control unit 13 outputs sound data associated with the case where the degree is small, for example, “It is hot today”. When the degree of prompting is medium, the display control unit 11 has a facial expression that is slightly reddish with a little more sweat as shown in FIG. Display a face image. At this time, the utterance control unit 13 is voice data associated when the degree of prompting is medium, and more voice data than the voice data associated when the degree of prompting is small, for example, "I sweat a lot."

  When the output value of the sensor unit 60 after the elapse of a predetermined time after displaying the face image of FIG. 3A is the same as or higher than the previous time, the degree setting unit 12 sets the degree of soot to “medium”. The display control unit 11 displays the face image shown in FIG. 3B, and the utterance control unit 13 outputs the voice data associated with the voice data when the degree of prompting is medium. To do.

  When the output value from the temperature sensor of the sensor unit 60 after the elapse of a predetermined time after displaying the face image of FIG. 3B is the same as or higher than the previous time, the degree setting unit 12 determines the degree of reduction. Set as “large”, the display control unit 11 displays the facial expression face image that turns red in the face with a lot of sweat shown in FIG. Then, the utterance control unit 13 outputs voice data associated when the degree of prompting is large, for example, “Hot, sweaty and face turned red”. Further, when the output value from the temperature sensor of the sensor unit 60 after the predetermined time has passed is the same as or higher than the previous time, the display of the facial image of the facial expression of (c) of FIG. 3 may be repeated. Further, an expression that encourages a greater degree may be displayed, or the display may be stopped. Such a display is performed to prompt the user to perform the cooling operation of the air conditioner.

  In the above description, the case of high temperature has been described as an example, but the degree of prompting the user to perform the heating operation of the air conditioner is set similarly in the case of low temperature, and facial images of facial expressions corresponding to the set degree of prompting are set. Show it. Further, in the above, when starting from the display of the face image of FIG. 3A, the degree is increased in three stages, and when starting from the display of the face image of FIG. 3B, the degree is increased in two stages. Although it is large, it can be changed in any number of steps. In addition, the degree is decreased in accordance with the output value from the sensor unit 60 in the middle of increasing the degree stepwise, and conversely, the degree in accordance with the output value from the sensor unit 60 in the middle of decreasing the degree stepwise. You may enlarge it.

  As described above, the degree setting unit 12 responds to the output value from the sensor unit 60 based on at least one of the output value from the sensor unit 60 and the elapsed time after the output value is out of the predetermined range. Set the degree of prompting the user to take action. Then, when the output value is out of the predetermined range, the display control unit 11 displays a facial image having a facial expression corresponding to the degree of prompting set by the degree setting unit 12. Therefore, the display of the facial image of the expression according to the degree of prompting can inform the user that the output value of the sensor unit is out of the predetermined range, and the user can behave according to the output value from the sensor unit 60. Can be encouraged. By setting the predetermined range to a value that is comfortable or safe for the user, it is possible to prevent an unfavorable environment such as discomfort and danger for the user. Furthermore, since the user is prompted by facial expressions, it is not intimidating, and the user can be urged while being softened or healed. As described above, the control unit 10 can control the robot 1 so as to prompt the user to take spontaneous action.

  A facial expression that prompts the user to take an action according to the output value from the sensor unit 60 is an expression that prompts the user to take an action to return the output value from the sensor unit 60 within a predetermined range (in the above example, to lower the temperature). If the output value from the sensor unit 60 of the robot 1 is out of the predetermined range, the face image having a facial expression corresponding to the degree of prompting is displayed to prompt the user to take an action for returning to the predetermined range. Can do.

  Further, by outputting audio data corresponding to the degree of prompting, the user can be prompted more effectively.

  Further, the degree setting unit 12 sets the degree of promotion to be increased stepwise according to the length of the elapsed time until the output value from the sensor unit returns to a predetermined range. By setting to increase in steps, it is possible to prompt the user effectively.

  The degree setting unit 12 sets the degree to be smaller than the previous value when the output value from the sensor unit changes in a direction approaching the predetermined range, and the output value from the sensor unit 60 is set to the predetermined range. The degree may be set to be greater than the previous time when the distance is changed away from the previous position.

  In this way, by reducing or enhancing the degree of prompting according to the change in the output value from the sensor unit 60, it is possible to display a facial image with a greater degree of prompting. Another facial expression image that is displayed when the output value from the sensor unit 60 changes in a direction approaching a predetermined range is, for example, a facial expression with a joyful expression to convey that discomfort is being resolved. May be. Moreover, the facial image of the expression of joy may change stepwise.

  Further, the degree setting unit 12 may change the degree of prompting based on the voice recognition result by the voice recognition unit 14. With such a configuration, the degree of prompting is changed according to the input voice by the user, and the facial expression is changed accordingly. Therefore, increasing the variation variation makes the facial expression richer and makes the user more loving the robot.

  In addition, you may make it display the face image of the facial expression according to the degree of prompting only when the robot 1 detects a user. The user may be detected by the camera unit 70 or, if the sensor unit 60 is provided with a human sensor, the human sensor.

  Similarly to the above, when the sensor unit 60 detects humidity, when the output value from the sensor unit 60 is high humidity outside the predetermined range set for humidity, the degree setting unit 12 outputs the output value. The degree of prompting the user to perform the dehumidifying operation of the air conditioner is set according to. In accordance with this degree, the display control unit 11 displays facial images of facial expressions. When the degree of prompting is “small”, the face image of the slightly sweated expression shown in FIG. 4A associated with the case where the degree of prompting is small is displayed, and the degree of prompting is “medium” In such a case, a face image with a slightly sweated expression shown in FIG. 4B associated with the case where the degree of prompting is medium is displayed. In addition, when the output value of the sensor unit 60 after a predetermined time has elapsed since the face image of FIG. 4A is displayed is the same as or higher than the previous time, the display control unit 11 ( The face image of b) is displayed. When the output value of the sensor unit 60 after the elapse of a predetermined time after displaying the face image of FIG. 4B is the same as or higher than the previous time, the display control unit 11 determines that the display control unit 11 of FIG. A face image with a lot of sweating expression is displayed.

  Also in these cases, the utterance control unit 13 performs step-by-step voice data associated with the degree of prompting, for example, “Do not steam”, “Steamed, sticky”, or “Steamed, unpleasant”. Audio output. Such a display is performed to prompt the user to perform a dehumidifying operation of the air conditioner. Similarly, in the case of low humidity, the degree of prompting the user to operate the humidifier may be set, and a facial image of a facial expression corresponding to the set degree of prompting may be displayed.

  Even when the sensor unit 60 detects illuminance, as described above, when the output value from the sensor unit 60 is low outside the predetermined range set for illuminance, the degree setting unit 12 determines whether the output value is low. The degree of prompting the user to turn on the lighting device is set. In accordance with this degree, the display control unit 11 displays facial images of facial expressions as follows. When the degree of prompting is “small”, the face image of the facial expression with open eyes shown in FIG. 5A and the face image with closed eyes shown in FIG. 5B are alternately displayed. The face image that blinks is displayed at a low frequency. When the degree of prompting is “medium”, the facial image shown in FIG. 5A and the facial image shown in FIG. The face image of is displayed. When the degree of prompting is “medium”, the frequency of alternately displaying the face image shown in FIG. 5A and the face image shown in FIG. Display facial images of facial expressions. Also in these cases, the utterance control unit 13 outputs voice data associated with the degree of prompting, for example, “has not darkened”, “has become invisible”, or “cannot be seen” step by step. . Such a display is performed to prompt the user to turn on the lighting device.

  The above is merely an example, and the display of a facial image of an expression according to the degree of prompting is not limited to the above. Further, in the above description, the case where facial expressions according to the output values from the temperature sensor, humidity sensor, and illuminance sensor are used individually has been described, but complex facial expressions are displayed according to the output values from a plurality of sensors. It may be configured to.
