A method includes arranging, by a computer, multiple interactive objects as a hierarchical data structure, each node of the hierarchical data structure associated with a respective one of the multiple interactive objects, and 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. A sequence of three-dimensional (3D) maps including at least part of a hand of a user positioned in proximity to the display is received, and the hand performing a transverse gesture followed by a grab gesture followed by a longitudinal gesture followed by an execute gesture is identified in the sequence of three-dimensional (3D) maps, and an operation associated with the selected object is accordingly performed.
