detecting a plurality of external devices in the environment;

transmitting the interrogation signal comprises transmitting an interrogation signal to at least some of the plurality of external devices in the environment; and

analyzing the stream of images to detect the change in the at least one aspect of the external device comprises differentiating among the plurality of external devices based on the detected change.

14. A method for visually pairing with an external device, the method comprising:

receiving a stream of images captured from an environment of a user of a wearable apparatus;

analyzing the stream of images to detect the external device in the environment of the user;

causing at least one transmitter associated with the wearable apparatus to transmit an interrogation signal, the interrogation signal being configured to cause a change in at least one aspect of the external device, the change including a change in illumination of at least one infrared or visible light source associated with the external device;

analyzing the stream of images to detect the change in the at least one aspect of the external device; and

after detection of the change in the at least one aspect of the external device, storing information relating to the external device.
