Abstract
A wearable computing device includes an electro-optical sensor to translate received light into an electrical signal. During a first mode of operation of the wearable computing device, a physical parameter of a wearer of the wearable computing device is assessed from the electrical signal. During a second mode of operation of the wearable computing device, encoded communication data is extracted from the electrical signal.
