Action control device, action control method, and recording medium

Abstract

An action control device that controls the actions of a robot acquires an external stimulus; and in a case of executing an action corresponding to the external stimulus, controls so as to execute, based on an intimacy between a subject applying the external stimulus and the robot, different action content.

1 . An action control device that controls an action of a control target device, the action control device comprising:
 a controller that
 acquires an external stimulus, and 
 in a case where the controller executes an action corresponding to the external stimulus, controls so as to execute, based on an intimacy between a subject applying the external stimulus and the control target device, different action content. 
   
     
     
         2 . The action control device according to  claim 1 , wherein the controller controls so as to determine, based on a result of comparing the acquired external stimulus and the external stimulus acquired previously, the intimacy between the control target device and the subject applying the external stimulus. 
     
     
         3 . The action control device according to  claim 2 , wherein
 the controller
 acquires a sound as the external stimulus, and 
 controls so as to determine, based on a level of similarity between a characteristic quantity of a predetermined parameter included in the acquired sound and a characteristic quantity of the predetermined parameter included in sound acquired previously, the intimacy with the subject applying the external stimulus. 
   
     
     
         4 . The action control device according to  claim 3 , wherein
 the controller sets, based on the level of the similarity, an action mode in which the action content is defined, and   the action mode includes a normal action mode in which action content executed regardless of the intimacy with the subject is defined, and an intimate action mode in which action content executed based on the intimacy with the subject is defined.   
     
     
         5 . The action control device according to  claim 4 , wherein the controller controls so that, after the action mode is set to the intimate action mode, when a determination is made that a predetermined amount of time set in accordance with the level of similarity has elapsed, the action mode is transitioned to the normal action mode. 
     
     
         6 . The action control device according to  claim 5 , wherein the predetermined amount of time differs in accordance with the determined intimacy. 
     
     
         7 . The action control device according to  claim 4 , wherein the controller controls so as to continue the intimate action mode when, for an external stimulus acquired when set to the intimate action mode, the similarity determined from the external stimulus is a predetermined level. 
     
     
         8 . An action control method comprising:
 acquiring, by a controller, an external stimulus; and   in a case of executing an action corresponding to the external stimulus, controlling so as to execute, by the controller and based on an intimacy between a subject applying the external stimulus and the control target device, different action content.   
     
     
         9 . The action control method according to  claim 8 , wherein the controller
 controls so as to determine, based on a result of comparing the acquired external stimulus and the external stimulus acquired previously, the intimacy between the control target device and the subject applying the external stimulus.   
     
     
         10 . The action control method according to  claim 9 , wherein
 the controller
 acquires a sound as the external stimulus, and 
 controls so as to determine, based on a level of similarity between a characteristic quantity of a predetermined parameter included in the acquired sound and a characteristic quantity of the predetermined parameter included in sound acquired previously, the intimacy with the subject applying the external stimulus. 
   
     
     
         11 . The action control method according to  claim 10 , wherein
 the controller sets, based on the level of the similarity, an action mode in which action content is defined, and   the action mode includes a normal action mode in which action content executed regardless of the intimacy with the subject is defined, and an intimate action mode in which action content executed based on the intimacy with the subject is defined.   
     
     
         12 . A non-transitory computer-readable recording medium storing a program, the program causing a computer to:
 acquire an external stimulus; and   in a case of executing an action corresponding to the external stimulus, control so as to execute, based on an intimacy between a subject applying the external stimulus and the control target device, different action content.   
     
     
         13 . The non-transitory computer-readable recording medium according to  claim 12 , wherein the program causes the computer to control so as to determine, based on a result of comparing the acquired external stimulus and the external stimulus acquired previously, the intimacy between the control target device and the subject applying the external stimulus. 
     
     
         14 . The non-transitory computer-readable recording medium according to  claim 13 , wherein the program causes the computer to:
 acquire a sound as the external stimulus, and   control so as to determine, based on a level of similarity between a characteristic quantity of a predetermined parameter included in the acquired sound and a characteristic quantity of the predetermined parameter included in sound acquired previously, the intimacy with the subject applying the external stimulus.   
     
     
         15 . The non-transitory computer-readable recording medium according to  claim 14 , wherein
 the program causes the computer to set, based on the level of the similarity, an action mode for which the action content is defined, and   the action mode includes a normal action mode in which action content executed regardless of the intimacy with the subject is defined, and an intimate action mode in which action content executed based on the intimacy with the subject is defined.
