task may, thus, permit a user to command a system using a signal that is intuitive, repeatable, and voluntary even while their hands, or other body portions, associated with one or more sensors are occupied. [0019] In some embodiments, a system may need to identify commands from a user that may be distinct from the signals generated by the sensors during normal performance of a task. That is, the system may need to distinguish between task signals (i.e., sensor signals associated with nominal performance of a task) and command signals that the user may generate to command a system to perform a desired operation of the system while the user is performing the task. Accordingly, in one embodiment, a system may include multiple sensors located on a user’s body. The multiple sensors may be configured to detect forces applied by corresponding portions of a user’s body and generate multiple signals in response to those applied forces. A system may further include a processor that receives the multiple signals. Based at least in part on the multiple received signals, the processor may identify commands from the user using an operational range of the signals associated with nominal performance of the task as detailed further below. [0020] In some embodiments, task signals and command signals may be distinguished after an appropriate calibration, initialization, or training period of the system. In the training period, the user may perform repeated executions of a given task, and the system may record the signals generated by the sensors. During the repeated executions of the task, only task signals may be generated. As such, the system may learn characteristics of the task signals associated with the given task to define an expected operational range of the signals during task performance. After the training period, when a user is performing the same task but may additionally wish to provide a command to the system, the system may be able to identify the command signals that may be superimposed on the task signals. That is, the user may intentionally apply signals outside of the expected operational range of the sensors in order to communicate commands to the system. Of course, embodiments in which a system is already calibrated with an expected operational range of signals associated with performance of a given task are also contemplated as the disclosure is not limited to how this range is established. Specific ways in which the operational range of signals generated during task performance used to identify commands from a user are discussed further below.
