12. The device of claim 7 , wherein the operations further comprise: receiving information associated with a physical attribute of the user; creating a body language profile based upon the information associated with the physical attribute of the user; and causing the body language profile to be stored; and wherein selecting the body language reference model to compare to the modified signal received from the sensor network comprises selecting the body language reference model to compare to the modified signal based, at least in part, upon the body language profile.
7. A device comprising: a processor; and a memory that stores computer-readable instructions that, when executed by the processor, cause the processor to perform operations comprising generating a signal, sending the signal to a sensor network associated with a user, wherein the sensor network comprises a plurality of vibration sensors positioned at various locations on a body of the user, receiving a modified signal from the sensor network, wherein the modified signal comprises the signal received, from the device, by at least one vibration sensor of the plurality of vibration sensors and propagated by the at least one vibration sensor through at least one bone of the body of the user, thereby modifying the signal to create the modified signal, selecting a body language reference model to compare to the modified signal received from the sensor network, wherein the body language reference model identifies a plurality of body language features and associated signal features, comparing the modified signal to the body language reference model, determining, based upon comparing the modified signal to the body language reference model, a signal feature of the modified signal that maps to a body language feature of the plurality of body language features identified in the body language reference model, and outputting the body language feature of the plurality of body language features identified in the body language reference model to an application.
