Abstract
An in-car phone localization scheme is proposed to determine, in real time, the locations of smartphones inside a moving car, with the goal of preventing smartphone-distracted driving. The localization system operates on commodity smartphones, and does not require any additional special/customized sensors or devices to be installed inside the car, making its deployment easy and attractive to users and carmakers. Even when a phone is moved from one location to another inside a moving car, the system will detect this movement, record the sensor data, and estimate the phone's destination location. The system captures the trajectory of each phone movement, the change of magnetic field, and the RSSI readings from the car Bluetooth transceiver, and then estimates the phone's destination location by matching the trajectory with the variation of magnetic field and the Bluetooth RSSI readings.
