1. A method for processing gesture input, the method comprising:
determining a virtual gesture-space defined in a received input frame of a sequence of frames, the virtual gesture-space being associated with a primary user from a ranked user list of one or more users and the virtual gesture-space being smaller than a total field of view captured in the received input frame;
processing only the virtual gesture-space in one or more frames in the sequence of frames to detect and track a hand;
using a hand bounding box generated by detecting and tracking the hand, performing gesture classification to determine a gesture input associated with the hand; and
outputting the determined gesture input to cause processing of a command input associated with the determined gesture input.
