Abstract: An object growth control system and method are provided. The object growth control system includes a weighting unit, a growth state analyzer, and an object operation controller. The weighting unit detects external environments and a user's state, loads weights on predetermined user emotional states, predetermined object growth tendencies, and predetermined object emotional states according to the result of detection and the user's tendency, and outputs the results of loading of the weights as state data. The growth state analyzer applies a predetermined statistical model to the state data input for a predetermined period to analyze the user's tendency and outputs a degree of education on the object with respect to the user's tendency based on the state data to which the predetermined statistical model has been applied.

Abstract: An apparatus and method for perceiving a physical and emotional state, which allows easy attachment to and detachment from a human body, and through which a bio-signal is simply detected, are provided. The apparatus includes a bio-signal detection part attached to a predetermined portion of a body for performing analog signal processing on at least one bio-signal detected from the body and outputting the processed bio-signal, and a bio-signal recognizing part for performing digital signal processing on the processed bio-signal received from the bio-signal detection part, perceiving the physical and emotional state from the result of the digital signal processing, and representing the physical and emotional state.

Abstract: Disclosed is a nervous system-based emotion synthesizing apparatus which enables an emotion of a humanoid to be synthesized in a manner similar to that of a human using a nervous system-adjusting mechanism of a human body according to emotions The human nervous system-based emotion synthesizing apparatus, includes a stimulus sensor portion having at least a stimulus sensor for sensing an external stimulus, an emotion generator for generating an predetermined emotion corresponding to the sensed external stimulus, a physiological signal generator for generating at least one artificial physiological signal in response to the sensed stimulus and the generated emotion, and an emotional behavior generator for generating at least one emotional behavior through a predetermined physical reaction in response to the sensed stimulus and the generated emotion, whereby the generated artificial physiological signal is fed back to the emotion generator and the emotional behavior generator, and the generated emotional behavio
