Acceleration- or magnetometer-based checks of GPS location?

[kshunterco]

Hi,

I am working on an indoor navigation app to help people with intellectual and developmental disabilities (IDDs) compete tasks of daily living, like going to a supermarket. In early research, we simply created (2D) indoor maps based on measurements for proof-of-concept, but as we try to expand usability, we need to enable caretakers to be able to create their own maps - which means allowing them to put down waypoints indoors (and likely adding our own internal waypoints as they travel along indoor paths). We have some experience with using accelerometers to track location (noisy!!!) but are wondering if this app (or others) have already made progress on using non-GPS technology to create map locations. If not, no worries.

Thanks

Hi Kendall,

OpenTracks only records data as provided by the GPS (position) or other sensors (speed, cadence etc).
It has itself no concept of a map or routing capabilities.

For indoor navigation usually Wifi or Bluetooth beacons are used - however, require a defined setup (at least some calibration phase).

What you could look for is using using cameras to capture the indoor environment (at least for mapping).
Then drawing waypoints becomes feasible - however, navigation is a different story.

No, OpenTracks doesn't do anything in this regard.
If a sensor provides absolute position, it will be used. All the heavy lifting is done in Android (e.g. network-based location or beacon-based) or actual physical sensor like GPS.

Thanks! Guess I should have expected as much, given what I've seen so far in indoor navigation.
