Abstract

Methods, systems, computer-readable media, and apparatuses for determining a position indicator are presented. In some embodiments, position data indicating a position of a mobile device is obtained. A position indicator is determined based on at least one region of a map. The position of the mobile device is located within the at least one region. The position indicator indicates a map-feature-dependent region of the map. The position indicator is provided.

First claim

What is claimed is:

1 . A method for determining a position indicator, comprising:
obtaining position data indicating a position of a mobile device; determining the position indicator based on at least one region of a map, wherein the position of the mobile device is located within the at least one region, wherein the position indicator indicates a map-feature-dependent region of the map; and providing the position indicator.

2 . The method of claim 1 , wherein the determining the position indicator is further based on at least one of a privacy setting, an accuracy level of the position data, a variation of the position over a span of time, or any combination thereof.

3 . The method of claim 1 , further comprising displaying, by a display, the position indicator and the map.

4 . The method of claim 2 , wherein the accuracy level is determined using a horizontal dilution of precision (HDOP) value.

5 . The method of claim 2 , wherein the position data includes received signal strength indication (RSSI) data received by the mobile device from at least one access point (AP), wherein the accuracy level is determined using minimum number of access points (APs) with an associated RSSI exceeding a threshold value.

6 . The method of claim 2 , wherein the accuracy level includes a minimum divergence between the position data for a period of time and output of an accelerometer of the mobile device for the period of time.

7 . The method of claim 1 , wherein the map-feature-dependent region of the map is a room of a floor plan.

8 . The method of claim 1 , wherein the map-feature-dependent region of the map is a geographical subdivision.

9 . The method of claim 1 , wherein the position indicator has a shape indicating the shape of the map-feature-dependent region.

10 . A system for determining a position indicator, the system comprising:
a processor; and a memory coupled to the processor and configurable for storing instructions; wherein the processor is configured to:
obtain position data indicating a position of a mobile device;
determine the position indicator based on at least one region of a map, wherein the position of the mobile device is located within the at least one region, wherein the position indicator indicates a map-feature-dependent region of the map; and
provide the position indicator.

11 . The system of claim 10 , wherein the determining the position indicator is further based on at least one of a privacy setting, an accuracy level of the position data, a variation of the position over a span of time, or any combination thereof.

12 . The system of claim 10 , further comprising a display, wherein the position indicator and the map are displayed by the display.

13 . The system of claim 11 , wherein the accuracy level is determined using a horizontal dilution of precision (HDOP) value.

14 . The system of claim 11 , wherein the position data includes received signal strength indication (RSSI) data received by the mobile device from at least one access point (AP), wherein the accuracy level is determined using a minimum number of access points (APs) with an associated RSSI exceeding a threshold value.

15 . The system of claim 11 , wherein the accuracy level includes a minimum divergence between the position data for a period of time and an output of an accelerometer of the mobile device for the period of time.

16 . The system of claim 10 , wherein the map-feature-dependent region of the map is a room of a floor plan.

17 . The system of claim 10 , wherein the map-feature-dependent region of the map is a geographical subdivision.

18 . The system of claim 10 , wherein the position indicator has a shape indicating the shape of the map-feature-dependent region.

19 . A non-transitory computer-readable storage medium storing computer executable code for determining a position indicator, comprising:
obtaining position data indicating a position of a mobile device; determining the position indicator based on at least one region of a map, wherein the position of the mobile device is located within the at least one region, wherein the position indicator indicates a map-feature-dependent region of the map; and providing the position indicator.

20 . The non-transitory computer-readable storage medium of claim 19 , wherein the determining the position indicator is further based on at least one of a privacy setting, an accuracy level of the position data, a variation of the position over a span of time, or any combination thereof.

21 . The non-transitory computer-readable storage medium of claim 19 , further comprising displaying, by a display, the position indicator and the map.

22 . The non-transitory computer-readable storage medium of claim 20 , wherein the accuracy level is determined using a minimum horizontal dilution of precision (HDOP) value.

23 . The non-transitory computer-readable storage medium of claim 20 , wherein the accuracy level includes a minimum divergence between the position data for a period of time and output of an accelerometer of the mobile device for the period of time.

24 . The non-transitory computer-readable storage medium of claim 19 , wherein the map-feature-dependent region of the map is a room of a floor plan.

25 . The non-transitory computer-readable storage medium of claim 19 , wherein the map-feature-dependent region of the map is a geographical subdivision.

26 . The non-transitory computer-readable storage medium of claim 19 , wherein the position indicator has a shape indicating the shape of the map-feature-dependent region.

27 . A mobile device for determining a position indicator, comprising:
means for obtaining position data indicating a position of the mobile device; means for determining the position indicator based on at least one region of a map, wherein the position of the mobile device is located within the at least one region of the map, wherein the position indicator indicates a map-feature-dependent region of the map; and means for providing the position indicator.

28 . The mobile device of claim 27 , wherein the determining the position indicator is further based on at least one of a privacy setting, an accuracy level of the position data, a variation of the position over a span of time, or any combination thereof.
