Abstract
Systems, methods, software and apparatus enable linking of a wearable end user communication device (EUD) to an intermediate communication device (ICD) utilizing optical symbol sequence matching. Optical symbol reference data corresponding to an optical symbol sequence displayed on the EUD is obtained from the EUD by the ICD. Optical symbol input data is also acquired by the ICD (e.g., via user inputs, EUD device proximity data, image acquisition). The devices are linked if the optical symbol reference data and optical symbol input data match. The optical symbol reference data can be displayed, allowing user confirmation of a match with the optical symbol sequence displayed on the EUD. An ICD user interface touchscreen can present users with selectable color inputs to replicate the optical symbol sequence displayed on the EUD, for example using an LED array. Communications between the devices before and after linking can utilize Bluetooth low energy.
