1. A computer implemented method for conducting machine control, comprising: conducting scanning of a region of space including: directing at least two emission cycles to form at least two scan patterns from an emission region to a region of space that might include a control object; detecting a reflectance of the at least two scan patterns; and determining that the detected reflectance indicates a presence of an object in the region of space; determining a first object attribute set of one or more object attributes of the object for a first one of the at least two scan patterns and a second object attribute set of one or more object attributes of the object for a second one of the at least two scan patterns; analyzing the first object attribute set and the second object attribute set to determine a potential control portion of the object; comparing the first object attribute set and the second object attribute set to determine control information; and responding to the indicated control information according to response criteria.
