Abstract
A functional device includes a light sensor for outputting a signal control signal relative to received light, a temperature sensor for outputting an additional control signal relative to an ambient temperature, a control means for controlling the signal control signal, and an output means for outputting a sensory signal perceivable by a sensory organ based on the signal control signal. The control means controls the signal control signal by using the additional control signal.
