Claim Text:
1. A method comprising, at a mobile device: estimating a trajectory of said mobile device within a particular environment comprising an indoor region, said trajectory extending from a first position towards a second position; determining a measure of potential hindrance for at least a portion of said trajectory based, at least in part, on an electronic map that is indicative of a presence or an absence of one or more obstacles within at least said portion of said trajectory; and presenting an indication of a position uncertainty to a user of said mobile device, said position uncertainty being based, at least in part, on said measure of potential hindrance, wherein said indication of said position uncertainty indicates an increased position uncertainty responsive to a higher measure of potential hindrance for said at least a portion of said trajectory and said indication of said position uncertainty indicates a decreased position uncertainty responsive to a lower measure of potential hindrance.
