1. A wearable computing device comprising:

  • a band configured to couple the wearable computing device to a wrist of a wearer;

    an electro-optical sensor arranged on the band to face the wrist and configured to translate received light into an electrical signal;

    an alignment mechanism configured to align the electro-optical sensor with an optical emitter of a communication cable, wherein the wearable computing device is configured to sense connection of the communication cable;

    a logic machine; and

    a storage machine holding instructions executable by the logic machine to;

    during a first mode, assess a physical parameter of the wearer of the wearable computing device from the electrical signal; and

    during a second mode, extract communication data encoded in the electrical signal that is translated, via the electro-optical sensor, from light received from the optical emitter of the communication cable, and wherein the wearable computing device is configured to automatically switch from the first mode to the second mode based on sensing connection of the communication cable to the wearable computing device.
