摘要:
Reproducing characteristics of an audio sound are controlled by an audio controller 8 and reproducing characteristics of a video image are controlled by a video controller 11. Whether or not a viewpoint of the user is directed to a display 13 side of a television receiver is detected by a viewpoint detector 14. On the basis of a detection signal from the viewpoint detector 14, a discriminating unit 15 discriminates which of a normal monitoring state, a "while watching" state, and the "concentration" state the present state corresponds to, and generates a control signal to control the reproducing characteristics so as to be adaptive to the state. If it is determined that the present state changes from the "while watching" state to the "concentration" state, a sound volume is reduced and the reproducing characteristics are automatically switched so as not to obstruct the concentration.
摘要:
An image-generating unit receives numerical values and outputs an image that varies according to changes in the numerical values. The numerical values are bio-information measured by a bio-information sensor and environmental information measured by an environmental sensor. Since the bio-information and the environmental information are variables whose changes are unpredictable, an output image changes in a variety of forms. The image generated by the image-generating unit is displayed on a displaying unit.
