Device Capability

Plain old motion tracking on the devices is quite stable, with minor drift over large amounts of movement. However, capturing a good sufficient ADF can be quite the chore, and the area learning occasionally makes mistakes which can result in wildly varying interpretations of a space though they are usually short lived. This issue is compounded if there are lots of objects moving through the space during play, or if the area capture is from a different time of day with different lighting.

For these reasons it is recommended that areas are always scanned before starting a game unless the same area was used immediately prior even if all devices already know the space, and play should generally be done in areas with minimal through traffic.
