    presenting, on a display coupled to the computer, a first subset of the multiple interactive objects that are associated with one or more child nodes of one of the multiple interactive objects;

    receiving a sequence of three-dimensional (3D) maps including at least part of a hand of a user positioned in proximity to the display;

    identifying, in the sequence of three-dimensional (3D) maps, the hand performing a transverse gesture followed by a grab gesture followed by a longitudinal gesture followed by an execute gesture;

    selecting, in response to the transverse gesture, an object from the first subset of the multiple interactive objects; and

    performing, in response to the grab gesture, the longitudinal gesture and the execute gesture, an operation associated with the selected object.
