Being able to tell a responder roughly what floor a user is on if help is requested
The app could potentially use the barometer in some smartphones such as newer iPhones to better locate people within buildings if help is requested, the barometer could be used to roughly tell a responder what floor the user is on in order to reach them quicker.
Thanks for the feedback. The way we understand the barometer and altimeter function on the newer iPhones is that it returns an altitude rather than an elevation, which means each building would need to have a base altitude configured to give a meaningful estimate. We also have concerns around accuracy and efficacy of using elevation to determine floor number. Currently we provide indoor positioning solutions utilising BLE iBeacon technology. To discuss this please ask your organisation to contact firstname.lastname@example.org. We will take a look at this suggesting though just in case there is something we missed.
