1. A method for assigning a gesture dictionary, comprising: determining a characteristic of a user that is independent of a motion or pose made by the user; correlating the characteristic of the user to a first gesture dictionary of a plurality of gesture dictionaries, each gesture dictionary of the plurality of gesture dictionaries identifying a set of input commands to the computer that may be invoked by a performance of a corresponding gesture; assigning the first gesture dictionary to the user, the first gesture dictionary corresponding to the characteristic; and processing captured data with the first gesture dictionary to identify whether a second motion or pose by the user in the captured data invokes an input command to the computer.
