In the exemplary embodiment, the interaction device  100  at least includes a biomedical sensor  10 , a processor  20 , a number of indicator lights  30 , and a storage device  40 . The indicator lights  30  have different colors. The biomedical sensor  10  detects physiological data of a user, such as heart rate, blood pressure, respiratory rate. The storage device  40  stores a first relationship between a number of physiological data ranges and a number of colors of the indicator lights. The processor  20  determines which color of the indicator lights  30  should be turned on, according to the detected physiological data and the first relationship stored in the storage device  40 . Then the processor  20  controls one indicator light  30  having the determined color to turn on, to indicate the emotion or mood of the user.
