CROSS-REFERENCE TO RELATEDAPPLICATIONS SENSING AND CONTROL SYSTEMS [0001] This application claims the benefit under 35 U.S.C. § 119(e) of U.S. provisional application serial number 62/832,684 filed April 11, 2019, the disclosure of which is incorporated by reference in its entirety. FIELD [0002] Disclosed embodiments are related to sensing and control systems. [0003] A user interacting with a system may wish to provide commands to the system in a manner that is easy and intuitive. Past work on providing commands from a user to a system has focused on finding a physically independent signal, such as control architecture based on EMG signals. However, even when given a physically independent signal, the user may not be able to take advantage of the signal due to a cognitive bottleneck. [0004] In one embodiment, a system includes a plurality of sensors and a processor. The plurality of sensors are configured to be worn on a user’s body and to detect forces applied by corresponding portions of a user’s body. The plurality of sensors generate a plurality of signals. The processor receives the plurality of signals, and identifies commands from the user based at least partly on the plurality of signals. The processor identifies commands from the user based at least partly on an operational range and/or null space of the plurality of signals for a task being performed by the user. The processor controls an operation of the system based on the identified commands. [0005] In another embodiment, a method for controlling a system includes receiving a plurality of signals from a plurality of sensors worn by a user, wherein the plurality of sensors detect forces applied by corresponding portions of a user’s body. The method includes identifying commands from the user based at least partly on the plurality of signals and an BACKGROUND SUMMARY
