1. A user wearable augmented reality (AR) system, comprising:
a viewing device operable to output AR data to a user, the viewing device comprising a secondary orientation sensor; and
a power pack linked to the viewing device, wherein the power pack comprises:
a power supply;
a primary orientation sensor operable to measure a power pack orientation;
an orientation engine, operable in response to polling the primary orientation sensor at a first rate so as to calculate a viewing device orientation on a basis of a relationship between the power pack orientation and the viewing device orientation; and
an AR engine, operable to generate AR data for output by the viewing device, wherein the AR data varies in response to the calculated viewing device orientation, and wherein the orientation engine is operable to determine or update the relationship between the power pack orientation and the viewing device orientation by polling the secondary orientation sensor in the viewing device at a second rate that is lower than the first rate.
