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.

Claims

1. A method for determining a position indicator, comprising:

obtaining position data indicating a position of a mobile device;

accessing a map based on the position of the mobile device, the map having a plurality of regions wherein each region is bounded by one or more features of the map;

determining the position indicator based on;

the position of the mobile device, and

at least one region of the plurality of regions of the map, wherein the position of the mobile device is located within the at least one region,

wherein a type of the position indicator is determined 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,

wherein the type of position indicator is indicative of a shape of the at least one region of the map; and

displaying the position indicator on a device display.

2. The method of claim 1, further comprising displaying, by the device display, the map.

3. The method of claim 1, wherein the accuracy level is determined using a horizontal dilution of precision (HDOP) value.

4. The method of claim 1, 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.

5. The method of claim 1, 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.

6. The method of claim 1, wherein the at least one region of the map is a room of a floor plan.

7. The method of claim 1, wherein the at least one region of the map is a geographical subdivision.

8. 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;

access a map based on the position of the mobile device, the map having a plurality of regions wherein each region is bounded by one or more features of the map;

determine the position indicator based on;

the position of the mobile device, and

at least one region of the plurality of regions of the map, wherein the position of the mobile device is located within the at least one region,

wherein the processor is configured to determine a type of the position indicator 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; and

display the position indicator on a device display.

9. The system of claim 8, wherein the map is displayed by the device display.

10. The system of claim 8, wherein the accuracy level is determined using a horizontal dilution of precision (HDOP) value.

11. The system of claim 8, 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.

12. The system of claim 8, 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.

13. The system of claim 8, wherein the at least one region of the map is a room of a floor plan.

14. The system of claim 8, wherein the at least one region of the map is a geographical subdivision.

15. 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;

accessing a map based on the position of the mobile device, the map having a plurality of regions wherein each region is bounded by one or more features of the map;

determining the position indicator based on;

the position of the mobile device, and

at least one region of the plurality of regions of the map, wherein the position of the mobile device is located within the at least one region,

wherein a type of the position indicator is determined 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; and

displaying the position indicator on a device display.

16. The non-transitory computer-readable storage medium of claim 15, further comprising displaying, by the device display, the map.

17. The non-transitory computer-readable storage medium of claim 15, wherein the accuracy level is determined using a minimum horizontal dilution of precision (HDOP) value.

18. The non-transitory computer-readable storage medium of claim 15, 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.

19. The non-transitory computer-readable storage medium of claim 15, wherein the at least one region of the map is a room of a floor plan.

20. The non-transitory computer-readable storage medium of claim 15, wherein the at least one region of the map is a geographical subdivision.

21. A mobile device for determining a position indicator, comprising:

means for obtaining position data indicating a position of the mobile device;

means for accessing a map based on the position of the mobile device, the map having a plurality of regions wherein each region is bounded by one or more features of the map;

means for determining the position indicator based on;

the position of the mobile device, and

at least one region of the plurality of regions of the map, wherein the position of the mobile device is located within the at least one region of the map,

wherein a type of the position indicator is determined 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; and

means for displaying the position indicator on a device display.
