[0021] In the embodiments described herein, a system may be used generally to control one or more operations of any applicable system capable of being controlled by an input from a user. For example, a user may control a robot using the system. The robot could take any of a number of form factors, but supernumerary robotic limbs (SRLs) may be especially interesting. A user may be able to provide commands to the SRLs using sensors disposed on the user’s hands, even while the user’s hands are otherwise engaged. The commands communicated to the system may be general control commands related to motions, actions, or adjustments of the system. In addition, specialized commands may be useful. For example, a user may send a command to enable an emergency stop function to the system, even while the user’s hands are constrained. Such an application has obvious benefits for user safety. 

[0022] The multiple sensors of the systems described herein may be disposed at any location on the body of a user where a sensor signal may be manipulated. Humans have the most dexterous control of and most sensing feedback from their hands, as illustrated by large portions of the sensory and motor cortex devoted to the hands. Thus, one attractive solution may be to locate sensors on one or more portions of one or more hands of the user, including the fingers. Of course, other sensor locations are possible. Sensors may be located on any portion of a user’s body that may change states that a sensor can sense. For example, sensors located on a user’s shoulders may detect when the user shrugs their shoulders. Sensors located on a user’s elbows may sense when a user extends their arms. Sensors may be located on a user’s foot, ankle, knee, hip, shoulder, elbow, wrist, finger, or neck, to name a few examples. The multiple sensors of the system may be placed in any of a number of appropriate locations on the user’s body, as the disclosure is not limited in this regard. [0023] In some applications, sensor positions that constrain actions associated with certain tasks may be undesirable. For example, sensors located on the palms of a user’s hand may interfere with grasping tasks. As such, in some embodiments, sensor locations may be chosen so as to be unobtrusive and limit any constraints or interference in a task caused by the sensors. For example, placing sensors on multiple fingertips of a user may provide a rich source of signals while not interfering with a task. 

[0024] It should be understood that a system may use any appropriate sensor types for
