Sensing Vehicle Dynamics for Determining Driver Phone Use
Distinguishing driver and passenger phone use is a building block for a variety of mobile applications. Its greatest promise lies in helping to reduce driver distraction. Cell phone distractions have been a factor in high-profile accidents and are associated with a large number of automobile accidents. This work utilizes smartphone sensing of vehicle dynamics to determine the driver phone use, which can facilitate many traffic safety applications. We explore a low-infrastructure approach that senses acceleration due to vehicle dynamics to decide phone position. Our system uses embedded sensors in smartphones, i.e., accelerometer and gyroscope, to capture differences in centripetal acceleration due to vehicle dynamics. These differences combined with angular speed can determine whether the phone is on the left or right side of the vehicle. Our approach involves low infrastructure and is flexible with different turn sizes and driving speeds. Extensive experiments conducted with two vehicles in two different cities demonstrate that our system is robust to real-road driving environments. Despite of the noisy sensor readings from smartphones, our approach can achieve a classification accuracy of over 90% with a few percent of false positive rate. We also find that by combining sensing results in a few turns, we can achieve better accuracy (e.g., 95%) with a lower false positive rate. Our recent study towards a completely infrastructure-free approach for driver phone use determination will also be discussed.
