Abstract:
An autonomic device behaving adaptively to a user, comprising:a sensing unit which senses signals of a user's command and predetermined user-related signals relevant to accomplishment of the command but not part of the command;a recognition unit which recognizes the user's command and a current user-related status based on the sensed signals of the command and the sensed predetermined signals;a first memory which stores the recognized command and the recognized user-related status;a pseudo-personality-forming unit which establishes each element of predetermined pseudo-personality elements based on the user-related status accumulated for a predetermined period of time in the first memory to form pseudo-personality, said pseudo-personality-forming unit having a memory storing a predetermined relationship between the predetermined pseudo-personality elements and the user-related status;a second memory which stores the formed pseudo-personality;a pseudo-emotion-forming unit which establishes each element of predetermined pseudo-emotion elements based on the user-related status stored in the first memory and the pseudo-personality stored in the second memory to form pseudo-emotions, said pseudo-emotion-forming unit having a memory storing a predetermined relationship between the predetermined pseudo-emotion elements, the user-related status, and the pseudo-personality;an autonomic behavior-establishing unit which selects a pattern of autonomic behavior based on the user-related status, the pseudo-personality, and the pseudo-emotions, said autonomic behavior-forming unit having a memory storing a predetermined relationship between patterns of autonomic behavior, the user-related status, the pseudo-personality, and the pseudo-emotions, each pattern constituted by plural predetermined elements;a new behavior pattern generation unit which generates new patterns of autonomous behavior by selecting and combining patterns' elements randomly or under predetermined rules, said new behavior pattern generation unit having a database storing a pool of elements of patterns of autonomous behavior, said generated new patterns transmitted to the memory of the autonomous behavior-establishing unit, wherein the new patterns override the previous patterns under predetermined conditions;a commanded behavior-establishing unit which constitutes a pattern of commanded behavior in accordance with the recognized user's command;a behavior control unit which controls behavior by combining the selected pattern of autonomic behavior and the constituted pattern of commanded behavior based on a predetermined priority order; andan output device which outputs the controlled behavior.
