Claim One:
1. A system for selecting one or more features to identify one or more human activities in a human-computer interacting environment, the system comprising: a processor; a non-transitory memory coupled to the processor, wherein the processor is capable of executing a plurality of modules stored in the memory, and wherein the plurality of modules comprise: a receiving module that receives skeleton points associated with one or more humans, wherein the one or more humans perform the one or more human activities, and wherein the skeleton points comprise a plurality of position coordinates of the one or more humans; a computation module that calculates a data variation factor for the skeleton points, wherein the data variation factor identifies a variation between two or more of the plurality of position coordinates of the one or more human; a selection module that selects a set of skeleton points from the skeleton points based on the data variation factor; a feature defining module that: identifies a change in position coordinates associated with the set of skeleton points by using one or more statistical parameters, wherein the set of skeleton points defines the one or more human activity to be identified; and extracts one or more features from the set of skeleton points based on the change in the position coordinates; and an identification module that uses the one or more features to identify the one or more human activities.
