Ways of communicating location, maybe also orientation generally, maybe not... do not overlap with Rotate
Precision vs. accuracy, CEP circles always exist... zoom in enough. Digital display of precision must also follow... new caliper uses 5/0 flip for last digit as mechanical guages always did!
Annunciator row, and asking people about it!
Problem
Solution
Variations
explicit - maps, CEP circles, etc.
background - notify, behave appropriately... permission (one off and Android-style on-install), annunicator and example of "in a meeting because at the right location at the right time"
