Abstract

An autonomous device behaving adaptively to a user includes a sensing unit; a recognition unit for recognizing user'"'"'s command, a current user-related status, and a current user-unrelated status based on the sensed signals; a pseudo-personality-forming unit for establishing a pseudo-personality based on the result of the preceding recognition; a pseudo-emotion-forming unit for establishing pseudo-emotions based on the result of the preceding recognition and the pseudo-personality; an autonomous behavior-establishing unit for selecting autonomous behavior based on the result of the preceding recognition, the pseudo-personality, and the pseudo-emotions; a commanded behavior-establishing unit for constituting commanded behavior in accordance with the user'"'"'s command; a behavior control unit for controlling behavior by combining the autonomous behavior and the commanded behavior; and an output device outputting the controlled behavior. The device comes to be viewed as a “pet” or a “friend” with the passage of time.

Claims

1. An autonomous 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 and updates 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 memorizing a predetermined relationship between the predetermined pseudo-personality elements and the user-related status;

a second memory which stores and updates the formed pseudo-personality, wherein updating takes place under predetermined conditions;

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 memorizing a predetermined relationship between the predetermined pseudo-emotion elements, the user-related status, and the pseudo-personality;

an autonomous behavior-establishing unit which selects a pattern of autonomous behavior based on the user-related status, the pseudo-personality, and the pseudo-emotions, said autonomous behavior-forming unit memorizing a predetermined relationship between patterns of autonomous behavior, the user-related status, the pseudo-personality, and the pseudo-emotions;

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 autonomous behavior and the constituted pattern of commanded behavior based on a predetermined priority order; and

an output device which outputs the controlled behavior.

2. The autonomous device according to claim 1, wherein:

the sensing unit further senses predetermined user-unrelated signals relevant to accomplishment of the command but not part of the command;

the recognition unit further recognizes a current user-unrelated status based on the sensed predetermined signals;

the first memory further stores and instantaneously updates the recognized user-unrelated status;

the pseudo-emotion-forming unit establishes each element of predetermined pseudo-emotion elements based further on the user-unrelated status in addition to the user-related status stored in the first memory and the pseudo-personality stored in the second memory to form pseudo-emotions;

the predetermined relationship memorized in the pseudo-emotion-forming unit further includes the user-unrelated status to define a relationship between the predetermined pseudo-emotion elements, the user-related status, the user-unrelated status, and the pseudo-personality;

the autonomous behavior-establishing unit selects a pattern of autonomous behavior based further on the user-unrelated status in addition to the user-related status, the pseudo-personality, and the pseudo-emotions; and

the predetermined relationship memorized in the autonomous behavior-forming unit further includes the user-unrelated status to define a relationship between patterns of autonomous behavior, the user-related status, the user-unrelated status, the pseudo-personality, and the pseudo-emotions.

3. The autonomous device according to claim 1, further comprising a third memory which stores and updates the pseudo-emotion formed by the pseudo-emotion-forming unit, said third memory being linked to the behavior control unit, wherein the second memory is further linked to the behavior control unit, wherein the pseudo-emotion stored in the third memory and the pseudo-personality stored in the second memory are used as parameters of the predetermined priority order provided in the behavior control unit.

4. The autonomous device according to claim 2, further comprising a third memory which stores and updates the pseudo-emotion formed by the pseudo-emotion-forming unit, said third memory being linked to the behavior control unit, wherein the second memory is further linked to the behavior control unit, wherein the pseudo-emotion stored in the third memory and the pseudo-personality stored in the second memory are used as parameters of the predetermined priority order provided in the behavior control unit.

5. The autonomous device according to claim 3, wherein the first memory is further linked to the behavior control unit, wherein the user-related status stored in the first memory, the pseudo-personality stored in the second memory, and the pseudo-emotion stored in the third memory are used as parameters of the predetermined priority order provided in the behavior control unit.

6. The autonomous device according to claim 4, wherein the first memory is further linked to the behavior control unit, wherein the user-related status stored in the first memory, the pseudo-personality stored in the second memory, and the pseudo-emotion stored in the third memory are used as parameters of the predetermined priority order provided in the behavior control unit.

7. A method for adapting behavior of a device to a user'"'"'s characteristics, comprising the steps of:

(a) sensing signals of a user'"'"'s command and predetermined user-related signals relevant to accomplishment of the command but not part of the command;

(b) recognizing the user'"'"'s command and a current user-related status based on the sensed signals of the command and the sensed predetermined signals;

(c) storing and updating the recognized command and the recognized user-related status;

(d) establishing each element of predetermined pseudo-personality elements based on the user-related status accumulated for a predetermined period of time in step (c) to form pseudo-personality, with the use of a memory storing a predetermined relationship between the predetermined pseudo-personality elements and the user-related status;
