A ubiquitous natural user system comprising: one or more sensors configured to provide sensed input including measurements of motion of a user during performance of a task by the user, the motion including a gesture performed in a three-dimensional zone in an environment of the user, the 3D zone being one of a plurality of 3D zones in the environment that are defined to accept respective, distinct gestures of the user; and a front-end system coupled to the one or more sensors, and configured to 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 being configured to identify the gesture based on the one of the plurality of 3D zones in which the gesture is performed, wherein the front-end system is configured to form and communicate an input to cause the electronic resource to perform the operations and produce an output, wherein the front-end system is configured to receive the output from the electronic resource, and communicate the output to a display device, audio output device or haptic sensor, wherein the gesture is a first gesture, and the motion further includes a second gesture performed in the environment of the user and that is distinct from the respective, distinct gestures that the plurality of 3D zones are defined to accept, and wherein the front-end system being configured to receive and process the sensed input includes being configured to receive and process the sensed input to further identify the second gesture, the operations of the electronic resource including operations identified from the first gesture and operations identified from the second gesture, the front-end system being configured to identify the second gesture without regard to the plurality of 3D zones. one or more sensors configured to provide sensed input including measurements of motion of a user during performance of a task by the user, the motion including a gesture performed in a three-dimensional zone in an environment of the user, the 3D zone being one of a plurality of 3D zones in the environment that are defined to accept respective, distinct gestures of the user; and a front-end system coupled to the one or more sensors, and configured to 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 being configured to identify the gesture based on the one of the plurality of 3D zones in which the gesture is performed, wherein the front-end system is configured to form and communicate an input to cause the electronic resource to perform the operations and produce an output, wherein the front-end system is configured to receive the output from the electronic resource, and communicate the output to a display device, audio output device or haptic sensor, wherein the gesture is a first gesture, and the motion further includes a second gesture performed in the environment of the user and that is distinct from the respective, distinct gestures that the plurality of 3D zones are defined to accept, and wherein the front-end system being configured to receive and process the sensed input includes being configured to receive and process the sensed input to further identify the second gesture, the operations of the electronic resource including operations identified from the first gesture and operations identified from the second gesture, the front-end system being configured to identify the second gesture without regard to the plurality of 3D zones.
