Abstract
In one embodiment, an apparatus (12) is presented that detects wireless signals from external devices (18) that uniquely identify each of the external devices, records, in memory (30), information about the external devices without access to an external database, and compares information from the external devices to determine a relative location of the wearable device without using additional, power-hungry position location functionality if there is a threshold match in the compared information. In some embodiments, the invention uses the determined relative location to trigger an action at another device. The invention, using self-contained functionality, enables improvements in same location or home location determination accuracy, memory conservation, and power consumption.
