Barometers are often used to improve motion tracking accuracy, not sure if this is a common use case for phones.
- stusmall 12y agoHow is that helpful in motion tracking?
- danbruc 12y agoWith sensor fusion you can improve the accuracy over just using GPS and accelerometers; it is quite common in quadcopters.
- RyJones 12y agoaltitude is usually the least accurate position given by a GPS. A barometer helps you get closer, faster.
- was_hellbanned 12y agoI have some MPX5100 pressure sensors connected up to an Arduino. When I first experimented with them, I was shocked to find that they were accurate enough to report pressure change simply from lifting the device off my desk and up to eye level. Not that this says anything about the sensor used in the iPhone, but it's not unreasonable to expect that it could be used as some form of motion input.
