Characterizing an indoor structure based on detected movements and/or position locations of a mobile device
First Claim
1. A method comprising, at a mobile device:
- in response to said mobile device accessing a radio signal heatmap to determine that said mobile device is entering or within an area of location uncertainty identified, at least in part, in said radio signal heatmap, gathering a plurality of measurements during a period of time, said plurality of measurements comprising at least a first measurement generated by one or more environmental sensors, and a second measurement generated by a radio based, at least in part, on one or more wireless signals received by said radio; and
in response to a determination that said mobile device is to report a travel history corresponding to at least a portion of said period of time;
generating a travel log for at least said portion of said period of time based, at least in part, on at least said first measurement and said second measurement; and
transmitting one or more signals representing said travel log to an external device.

Abstract
Various methods, apparatuses and articles of manufacture are provided which may be implemented in various devices for use in characterizing environments. In an example, a mobile device may, gather a plurality of measurements during a period of time, including one or more first measurements generated by one or more environmental sensors, and one or more second measurement generated by a radio based, at least in part, on one or more wireless signals received by the radio. In response to a determination that the mobile device is to report a travel history corresponding to at least a portion of the period of time, the mobile device may generate a travel log based, at least in part, on at least one first measurement and at least one second measurement, and transmit the travel log to an external device.

9. A mobile device comprising:
-
memory; a network interface comprising a radio; an environmental sensor; and a processing unit configured to; access a radio signal heatmap to determine whether said mobile device is entering or within an area of location uncertainty identified, at least in part, in said radio signal heatmap; in response to a determination that said mobile device is entering or within said area of location uncertainty, gather in said memory a plurality of measurements during a period of time, said plurality of measurements comprising at least a first measurement generated by said environmental sensor, and a second measurement generated by said radio based, at least in part, on one or more wireless signals received by said radio; and in response to a determination that said mobile device is to report a travel history corresponding to at least a portion of said period of time;
generate a travel log for at least said portion of said period of time based, at least in part, on at least said first measurement and said second measurement; and
initiate transmission of said travel log to an external device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus for use in a mobile device, the apparatus comprising:
-
means for gathering a plurality of measurements during a period of time, said plurality of measurements comprising at least a first measurement generated by one or more environmental sensors, and a second measurement generated by a radio based, at least in part, on one or more wireless signals received by said radio in response to said mobile device accessing a radio signal heatmap to determine that said mobile device is entering or within an area of location uncertainty identified, at least in part, in said radio signal heatmap; means for determining whether said mobile device is to report a travel history corresponding to at least a portion of said period of time; means for generating a travel log for at least said portion of said period of time based, at least in part, on at least said first measurement and said second measurement; and means for transmitting one or more signals representing said travel log to an external device. - View Dependent Claims (18, 19, 20)
