Abstract: Embodiments relate generally to a portable information device and associated wearable band and, more particularly, to thematic coordination of a portable information device and associated wearable band. One example embodiment includes a portable electronic information device comprising a display and a communication interface configured to receive identification from an attached wearable band—the received identification is used to determine one or more thematic elements intended to correspond with at least one visual attribute of a surface of the wearable band, and one or more of these thematic elements are presented on the information device display. Another example embodiment includes a wearable band comprising an interface configured for electrically coupling to a portable electronic information device—communication over the interface is used by the information device, the wearable band, or both to instantiate thematic coordination between the wearable band and the information device.
