Claim One:
1. A metabolic energy monitoring system comprising: a wearable device adapted to be worn on a human body and having a movement sensor providing movement information indicating a body motion, a temperature sensor providing temperature information indicating an amount of generated heat energy, and a pulse wave sensor providing pulse wave information indicating a pulse rate; a data server including an activity state decision unit determining a current activity state from a plurality of activity states based on the movement information and the activity state decision knowledge data, a metabolic state decision unit, a calorie consumption calculating unit calculating a calorie consumption value and a database storing activity state decision knowledge data and calorie consumption calculation knowledge data; and an output unit outputting the calorie consumption value, the plurality of activity states including a sleeping state, a resting state, and an active state, the calorie consumption calculation knowledge data including a first calorie consumption calculating algorithm that, upon being selected, calculates the calorie consumption value based on the movement information and a second calorie consumption calculating algorithm that, upon being selected, calculates the calorie consumption value based on the pulse wave information, the metabolic state decision unit detecting whether there is continuity of the current activity state, determining whether the temperature information and the pulse wave information indicate an ascending metabolic state upon detecting there is continuity of the current activity state, and selecting a current metabolic state from a plurality of metabolic states including a post-activity metabolic state and a metabolic state corresponding to each activity state of the plurality of activity states, the metabolic state decision unit selecting the post-activity metabolic state upon determining that the temperature information and the pulse wave information indicate the ascending metabolic state and determining that the current activity state is the active state, and the calorie consumption calculating unit selecting the first calorie consumption calculating algorithm upon the metabolic state decision unit selecting the current metabolic state to be a metabolic state other than the post-activity metabolic state, selecting the second calorie consumption calculating algorithm upon the metabolic state decision unit selecting the current metabolic state to be the post-activity metabolic state, and utilizing the selected calorie consumption calculating algorithm to calculate the calorie consumption value, wherein the selecting of the second calorie consumption calculating algorithm is based on the post-activity metabolic state being determined as a result of the current activity state being the active state and the temperature information and the pulse wave information indicating the ascending metabolic state, and the ascending metabolic state being determined upon a detection of continuity of the current activity state according to the movement information and the activity state decision knowledge data.
