Concepts and technologies are disclosed herein for surface determination via bone conduction. According to one aspect, a user device can identify a surface via bone conduction. The user device can identify one or more controllable devices to control using the surface. The user device can detect a user interaction, such as a gesture, performed by a user on the surface. The user device can provide an instruction to the controllable device(s) to cause the controllable device(s) to perform one or more operations in response to the user interaction with the surface.
