1. A method comprising:
identifying, by a user device, a surface via bone conduction, wherein the identifying comprises
generating a bone conduction signal,sending the bone conduction signal through a bone of a user and through the surface,receiving a modified bone conduction signal comprising the bone conduction signal as modified by the bone of the user and the surface,removing, from the modified bone conduction signal, a body characteristic associated with an effect of the bone of the user on the bone conduction signal,comparing the modified bone conduction signal sans the body characteristic to a plurality of surface signatures of a reference database, andreceiving, from the reference database, a surface identification associated with a surface signature of the plurality of surface signatures, wherein the surface signature uniquely identifies the surface to the user device; identifying, by the user device, a controllable device to control using the surface; detecting, by the user device, a user interaction with the surface; and providing, by the user device, an instruction to the controllable device to cause the controllable device to perform an operation in response to the user interaction with the surface. |
