This sounds like a very appropriate solution since GPS and WiFi are often only intermittently available indoors. Mapping programs are just starting to gather information about the insides of structures to make sense of tghe computed routes. It would be interesting to see the accumulated errors before a waypoint resolve after encountering the next one. I'm guessing the dead reckoning mapped route rescales to align with the known waypoints.

Yes, it must have a recalibration mechanism when fresh "reliable" data becomes available. The key here is the nature, cost and wider availability of the sensors used.

It's all in the details. Carry-context awareness is key, especially to avoid the erroneous reading of a 90 degree tilt. It's also important that this technology appears in a wide array of devices. The more pervasive, the more inherent to the user experience, the more indispensable in the long run.

Yet another indoor navigation technology

What's the accuarcy? Would it be a competitor of iBeacon indoor navigation? Or it is a complement.

Dead reckoning works anywhere, without beacons, say go get you to the indoor store at the mall, but once inside the story iBeacon could direct you to specific locations/shelf items.

Of course in practical devices, the sensor fusion that occurs can include other reference points such as RF beacon sensing to reduce the drift when GPS is unavailable.

In the end I'd expect in the most successful devices the software will integrate all avalable data including GPS, RF, video and the onboard movement and orientation sensors.

Stumble off a pier in Australia

Just read a news item where a woman tourist in Australia was so busy texting she walked off the end of a pier and had to be rescued.  Guess she should have used an outdoor navigation app...

@Zeeglen.....I'm sure there's Australians who could do that too. doesn't have to be a tourist.  Of course the main question is why, with Australia's culture of workplace safety and finding someone else to blame for your own incompetence, there was no railing at the end of said pier to stop people doing just this.  I can see the pier owners getting sued for not properly undertaking their "duty of care" to dumb phone users.....

BTW, did it say what happened to the phone??

Most likely a shark got it.  ("What are all those wierd noises in my stomach?")
