Claim Text:
1. A method of determining a position of an electronic device located within a moving vehicle, the method comprising: determining that the electronic device is located in a cabin of the vehicle based on first motion data provided by motion sensors of the electronic device; determining an average direction of motion of the electronic device using the first motion data; determine an average direction of motion of the electronic device over time; dividing an area representing the cabin into a front-right quadrant, a front-left quadrant, a back-right quadrant, and a back-left quadrant, based on the average direction of motion of the electronic device; receiving second motion data from the motion sensors; determining, using the second motion data, that the vehicle is accelerating; determining a rate of change of acceleration for the vehicle; receiving, from a barometer of the electronic device, first air pressure data within the vehicle; determining a rate of change of the air pressure within the vehicle based on the first air pressure data for a first time period, wherein the first time period starts after the vehicle starts accelerating and overlaps in time with a second time period during which the vehicle is accelerating; comparing the rate of change of the air pressure to the rate of change of the acceleration to determine that a reduction in air pressure within the vehicle at a beginning of the first time period was caused by the acceleration; determining that the device is located in the front-right quadrant based on a direction of the acceleration that caused the reduction in the air pressure being in a direction of the front-right quadrant; and changing a configuration of the electronic device.
