A psychological condition estimation system includes an acquisition unit and an estimation unit. The acquisition unit acquires information about respective activity levels of a plurality of sensory areas of a subject's brain. The estimation unit estimates a sense, which is highly related to the subject's psychological condition, out of a plurality of types of senses corresponding respectively to the plurality of sensory areas, based on the information, acquired by the acquisition unit, about the activity levels of the plurality of sensory areas when the subject is exposed to multiple types of stimuli.

A biological signal measurement system includes: a biological signal measurer that measures a biological signal including external noise of biological noise and of environmental noise; biological noise measurer that measures a signal including the biological noise; a biological noise estimator that estimates the biological noise from the signal measured by the biological noise measurer; an environmental noise measurer that measures a signal including the environmental noise; an environmental noise estimator that estimates the environmental noise from the signal measured by the environmental noise measurer; and a calculator that calculates the biological signal in consideration of an effect of the external noise using the signal measured by the biological signal measurer, the biological noise estimated by the biological noise estimator and the environmental noise estimated by the environmental noise estimator.

An illumination control system includes a signal detection unit for detecting a signal changed depending on an eye state of a person, an opening/closing determination unit for determining an opening/closing state of an eye of the person based on the detected signal, and a sight line detection unit for detecting a person's sight line direction with respect to an illumination device based on the detected signal. The illumination control system further includes a control unit for controlling the illumination device to reduce an illuminance when the opening/closing determination unit determines that the eye of the person is in a closed eye state, and to change an illuminance and a light color based on the sight line direction detected by the sight line detection unit when the opening/closing determination unit determines that the eye of the person is in an open eye state.
