1. A computationally-implemented method, comprising: soliciting to provide to a limb wearable computing device from one or more functional devices that are within the communication range of the limb wearable computing device gesture indicative data that is indicative of one or more user gestures, the communication range being a spatial volume that includes the limb wearable computing device and being externally defined by an enveloping boundary, where low-power signals transmitted by the limb wearable computing device being discernible over background noise within the enveloping boundary and not discernible over background noise outside the enveloping boundary, the limb wearable computing device being designed to be worn around a limb of a user; and facilitating the limb wearable computing device to receive the gesture indicative data from the one or more functional devices.
