A system is provided that includes sensor(s) configured to provide sensed input including measurements of motion of a user during performance of a task, and in which the motion may include a gesture performed in one of a plurality of 3D zones in an environment of the user that are defined to accept respective, distinct gestures. A front-end system may receive and process the sensed input including the measurements to identify the gesture and from the gesture, identify operations of an electronic resource. The front-end system may identify the gesture based on the one of the plurality of 3D zones in which the gesture is performed. The front-end system may then form and communicate an input to cause the electronic resource to perform the operations and produce an output. And the front-end system may receive the output from the electronic resource, and communicate the output to a display device.
