Claim 22:
23. A power pack for a user wearable augmented reality (AR) system of a type having a viewing device, the viewing device being operable to output AR data and the power pack linked to the viewing device, wherein the viewing device has a secondary sensor, the power pack comprising:
a power supply;
a primary orientation sensor operable to measure a power pack orientation;
an orientation engine operable in response to the primary orientation sensor to calculate a viewing device orientation at a first rate and 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, where 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.
