The broadband signal generator 1816 (illustrated and described in more detail below with respect to FIG. 18C) encodes parameters of the sensor signals 1806 to generate the actuator signals 1818. In one embodiment, the broadband signal generator 1816 extracts parameters from the sensor signals 1806 describing the message for transmission to a body 1826 of a user. The parameters may include changes in amplitude or frequency of the sensor signals 1806 over time or parameters of haptic input, such as pressure, temperature, sheer stress, duration, and space dimensions of a haptic touch.
The broadband signal generator 1816 generates broadband carrier signals (e.g., the broadband carrier signals 1828 shown below in FIG. 18B) by aggregating frequency components. The broadband signal generator 1816 generates the actuator signals 1818 by encoding the parameters from the sensor signals 1806 into the broadband carrier signals 1828. The bandwidth of the actuator signals 1818 is limited to the range of the responsiveness of the mechanical receptors of the body 1826, between 10 and 300 Hz. The actuator signals 1818 thus carry information from the sensor signals 1806 encoded within the broadband carrier signals 1828. Portions of the broadband signal generator 1816 may be implemented in software or hardware. For example, the broadband signal generator 1816 may be part of a PC, a tablet PC, an STB, a smartphone, an internet of things (IoT) appliance, or any machine capable of executing instructions that specify actions to be taken by that machine.
