The present invention relates to a user-interaction toy and an interaction method of the toy, and more particularly, to a user-interaction toy and an interaction method of the toy that recognize an intention of a user's action and select a reaction thereto, and output the intention and the reaction to a user. According to embodiments of the present invention, there is a provided a user-interaction toy that can more accurately determine a user's intention by sensing means including two or more sensors, and as a result, an appropriate response is made to a user to commune with the user through voice, sound, an action, and video, thereby enjoying the toy more vividly, a toy which interacts with the user.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method for recognizing, by a user's interaction toy (hereinafter, referred to as ‘user's interaction toy’), a user's intention and expressing a reaction thereto, the method comprising: (a) determining a meaning (hereinafter, referred to as ‘user's intention’) which a user intends to transfer the user-interaction toy based on information acquired by two or more different types of sensors sensing a stimulus (hereinafter, referred to as ‘input stimulus) caused by the user; and (b) selecting a reaction to be output to the user and outputting the selected reaction to the user based on the determined user's intention. 2. The method of claim 1, wherein in step (a), information acquired by the input of each sensor for the input stimulus is at least one of visual information, auditory information, tactile information, olfactory information, taste information, motion information, and pose information. 3. The method of claim 1, wherein step (a) includes: (a11) acquiring an input value for a specific stimulus of the user sensed by each of two or more different types of sensors; (a12) determining contents of information (hereinafter, referred to as ‘input information’) indicating the input stimulus sensed by the corresponding sensor by analyzing the input value sensed by each sensor; and (a13) determining the user's intention for the input information by combining the contents of the input information determined in step (a12). 4. The method of claim 1, further comprising: between steps (a) and (b), (b01) generating, when the user's intention is not confirmed in step (a), at least one output of the voice information, the sound information, the action information, and the video information for the user for the confirmation; and (b02) determining the user's intention based on the user's reaction to the output in step (b01). 5. The method of claim 1, wherein in step (b), when the reaction to be output to the user is selected and output to the user based on the determined user's intention, at least one of the voice information, the sound information, the action information, and the video information is output. 6. The method of claim 4, wherein in the case where the user's intention is confirmed or not confirmed in step (a), when the reaction to be output to the user is selected and output to the user, contents of the output are determined through a scenario stored in a database. 7. A user's interaction toy (hereinafter, referred to as ‘user's interaction toy’) recognizing a user's intention and expressing a reaction thereto, the toy comprising: a sensor input unit sensing a stimulus (hereinafter, referred to as ‘input stimulus’) caused by the user to acquire an input value for the input stimulus; an output unit generating an output corresponding to a user's input; a user's intention determination unit determining a meaning (hereinafter, referred to as ‘user's intention) which the user intends to transfer to the user-interaction toy based on information acquired by inputs of two or more different types of sensors of the sensor input unit sensing the input stimulus; an output determination unit selecting a reaction to be output to the user based on the user's intention determined by the user's intention determination unit; and a determination reference database storing reference data for determining the user's intention. 8. The toy of claim 7, wherein information acquired by the input of each sensor for the input stimulus is at least one of visual information, auditory information, tactile information, olfactory information, taste information, motion information, and pose information. 9. The toy of claim 7, further comprising: an input information content determination unit analyzing an input value of a specific input stimulus acquired by each of two or more different types of sensors of the sensor input unit to determine contents of information (hereinafter, referred to as ‘input information’) indicating the input stimulus sensed by the corresponding sensor, wherein the user's intention determination unit combines contents of the input information determined by the input information content determination unit by using the input value sensed in each sensor to determine the user's intention for the input stimulus. 10. The toy of claim 7, wherein the user's intention determination unit further includes an output information database further including a function to control the output determination unit to at least one output of the voice information, the sound information, the action information, and the video information for confirmation when the user's intention is not confirmed from the determination based on the information acquired by two or more different types of sensor inputs of the sensor input unit and determine the user's intention based on a user's reaction to the corresponding output, and storing at least one of the voice information, the sound information, the action information, and the video information. 11. The toy of claim 7, further comprising: when the output determination unit selects a reaction to be output to the user and outputs the selected reaction to the user based on the determined user's intention, an output information database outputting at least one of the voice information, the sound information, the action information, and the video information and storing at least one of the voice information, the sound information, the action information, and the video information. 12. The toy of claim 10, further comprising: in the case where the user's intention is confirmed or not confirmed by the user's intention determination unit, when the reaction to be output to the user is selected and output to the user, a scenario database storing a scenario to determine contents of the output.
