operational range and/or null space of the plurality of signals for a task being performed by the user, and controlling an operation of the system based on the identified commands. [0006] In yet another embodiment, a method for controlling a system includes: receiving a first plurality of signals from a plurality of sensors, wherein the first plurality of signals are associated with routine performance of a task; determining one or more command codes based at least in part on the first plurality of signals; receiving a second plurality of signals from the plurality of sensors during operation of the system; identifying the one or more command codes from the second plurality of signals; and controlling an operation of the system based on the identified command codes. [0007] It should be appreciated that the foregoing concepts, and additional concepts discussed below, may be arranged in any suitable combination, as the present disclosure is not limited in this respect. Further, other advantages and novel features of the present disclosure will become apparent from the following detailed description of various non- limiting embodiments when considered in conjunction with the accompanying figures. [0008] The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component that is illustrated in various figures may be represented by a like numeral. For purposes of clarity, not every component may be labeled in every drawing. In the drawings: [0009] FIG. 1A is an exploded view of one embodiment of a sensor of a system; [0010] FIG. 1B is a top view of one embodiment of a system that includes the sensor shown in FIG. 1A; [0011] FIG. 2 shows one embodiment of a system being used in a task; [0012] FIGs. 3A-3D show different arrangements of sensor activation for operation of a system; [0013] FIG. 4 is a flow diagram of one embodiment of a system; [0014] FIG. 5A is a graph of finger position data used to determine commands from a user in some embodiments of a system; BRIEF DESCRIPTION OF DRAWINGS
