Claim One:
1. A method for calculating an energy consumption based on three-dimensional (3D) motion tracking, comprising: obtaining a weight and a height of a user's body comprising a plurality of body segments, each body segment attached with a reference point; obtaining volumetric weights of each body segment by summing a body segment factor, a weight factor, and a height factor; selecting at least one body segment of the plurality of body segments as an analysis target; calculating a motion quantity of the analysis target by multiplying each volumetric weight of at least one body segment by an amount of a movement of respective reference point of the analysis target using a 3D vector to analyze the reference point; and determining an energy consumption of the analysis target on the basis of the motion quantity, wherein the weight factor is calculated by multiplying a first variable of the body segment and the weight, and wherein the height factor is calculated by multiplying a second variable of the body segment and the height.
