The broadband signal generator 1816 may generate the actuator signals 1818 by encoding the parameters from the sensor signals 1806 into the broadband carrier signals 1828 in a number of ways. In one embodiment, the physical location on the body 1826 of the user that is being actuated may be encoded into the broadband carrier signals 1828. For example, the location of the particular one or more actuators that are driven by the actuator signals 1818 convey information (e.g., identifying a particular phoneme) to the body 1826 of the user. In another embodiment, the amplitude of each frequency component of speech signals or the sensor signals 1806 can be used to encode information. In another embodiment, sequences of activation of different actuators can be used to encode information. In another embodiment, features of the power spectrum 1862 can be used. For example, actuator signals 1818 whose power is concentrated in the lower frequencies can convey different information than signals whose power is concentrated at higher frequencies. Non-linguistic applications are possible as well. For example, in simulated social touch using the haptic communication device 1820, broadband actuator signals 1818 convey a stimulus that is more natural than sinusoidal stimuli, which have an intense, artificial, mechanical sensation.
