In-Vehicle Phone Localization for Prevention of Distracted Driving
Chun‐Yu Chen, Kang Geun Shin · IEEE Transactions on Mobile Computing · 2022
A new in-vehicle phone localization scheme, calledDAPL(Detection andAlarming of in-vehiclePhoneLocation), is proposed to determine the locations of smartphones inside a moving car, with the goal of preventing smartphone-distracted driving.DAPLoperates on commodity smartphones and cars, and does not require additional special/dedicated hardware 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,DAPLwill detect this movement, acquire the sensor data, and estimate the phone's destination location.DAPLcaptures the trajectory of each phone movement, the change of magnetic field, and the RSSI readings from the Bluetooth transceiver built in most cars, and then estimates the phone's destination location by matching the trajectory with the variation of magnetic field and the Bluetooth RSSI readings. Our extensive experimentation has shownDAPLto achieve an average of 91.71% accuracy of in-car phone localization at low energy overhead, i.e.,$<$2.5% reduction of actual usage (screen-on) time.
