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, comprises:

an input unit which receives signals of a user'"'"'s command and other external signals;

a pseudo-personality-forming unit which establishes each element of predesignated pseudo-personality elements based on one or more of the other external signals accumulated for a predetermined period of time to form pseudo-personality, said pseudo-personality-forming unit storing a predesignated relationship between said pseudo-personality elements and said accumulated external signals;

a pseudo-emotion-forming unit which establishes each element of predesignated pseudo-emotion elements based on at least one predesignated signal of the other external signals and the pseudo-personality to form pseudo-emotions, said pseudo-emotion-forming unit storing a predesignated relationship between said pseudo-emotion elements, said external signals, and said pseudo-personality;

an autonomous behavior-establishing unit which selects a pattern of autonomous behavior based on at least one predesignated signal of the other external signals, the pseudo-personality, and the pseudo-emotions, said autonomous behavior-forming unit storing a predesignated relationship between patterns of autonomous behavior, said external signals, said pseudo-personality, and said pseudo-emotions;

a commanded behavior-establishing unit which constitutes a pattern of commanded behavior in accordance with the user'"'"'s command signals;

a behavior control unit which controls behavior by combining the selected pattern of autonomous behavior and the constituted pattern of commanded behavior; and

an output device which outputs the controlled behavior.

2. The device according to claim 1, wherein the input unit comprises sensors selected from the group consisting of a microphone, camera, touch sensor, keyboard, thermometer, light sensor, pressure sensor, obstacle sensor, movement sensor, and communication signal receiver.

3. The device according to claim 1, wherein the external signals include a signal of the user'"'"'s identification.

4. The device according to claim 1, wherein the output device includes facial parts, a tail, or translocating parts, and the patterns of autonomous behavior include movements or changes of the foregoing.

5. The device according to claim 1, wherein the selected patterns of autonomous behavior by the autonomous behavior-establishing unit include multiple patterns corresponding to the respective pseudo-emotions.

6. The device according to claim 1, wherein the behavior control unit combines the selected pattern of autonomous behavior and the constituted pattern of commanded behavior based on priority order determined by at least one predesignated signal of the other external signals the pseudo-personality, and the pseudo-emotions.

8. The method according to claim 2, wherein the signal receiving step comprises receiving signals by sensors selected from the group consisting of a microphone, camera, touch sensor, keyboard, thermometer, light sensor, pressure sensor, obstacle sensor, movement sensor, and communication signal receiver.

9. The method according to claim 2, wherein the external signals include a signal of the user'"'"'s identification.

10. The method according to claim 2, wherein the controlled behavior is outputted by a device includes facial parts, a tail, or translocating parts, and the patterns of autonomous behavior include movements or changes of the foregoing.

11. The method according to claim 2, wherein the selected patterns of autonomous behavior include multiple patterns corresponding to the respective pseudo-emotions.

12. The method according to claim 2, wherein in step (f), the selected pattern of autonomous behavior and the constituted pattern of commanded behavior are combined based on priority order determined by at least one predesignated signal of the other external signals, the pseudo-personality, and the pseudo-emotions.

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

(a) receiving signals of a user'"'"'s command and other external signals;

(b) establishing each element of predesignated pseudo-personality elements based on at least one predesignated signal of the other external signals accumulated for a predetermined period of time to form pseudo-personality, in accordance with a predesignated relationship between said pseudo-personality elements and said accumulated external signals;

(c) establishing each element of predesignated pseudo-emotion elements based on at least one predesignated signal of the other external signals and the pseudo-personality to form pseudo-emotions, in accordance with a predesignated relationship between said pseudo-emotion elements, said external signals, and said pseudo-personality;

(d) selecting a pattern of autonomous behavior based on at least one predesignated signal of the other external signals, the pseudo-personality, and the pseudo-emotions, in accordance with a predetermined relationship between patters of autonomous behavior, said external signals, said pseudo-personality, and said pseudo-emotions;

(e) constituting a pattern of commanded behavior in accordance with the user'"'"'s command signals;

(f) controlling behavior by combining the selected pattern of autonomous behavior and the constituted pattern of commanded behavior; and

(g) outputting the controlled behavior.
