History
The development of wearable items has taken several steps of miniaturization from discrete electronics over hybrid designs to fully integrated designs, where just one processor chip, a battery and some interface conditioning items make the whole unit.
Depending on how broadly one defines both wearable and computer, the first wearable computer could be as early as the first abacus on a string, or, later, a 16th century pocket watch. However common understanding is computer as a user-programmable item for complex algorithms, interfacing and data management.
