초록

웨어러블 디바이스의 대중화에 따라 디바이스 내에 탑재된 다양한 센서를 활용하여 동작 인식, 헬스케어, 안전 보조 등 다양한 스마트 서비스를 제공하는 애플리케이션이 급증하고 있다. 본 논문에서는 9축 관성 센서가 탑재된 스마트워치를 이용하여 운전자를 인식하고, 운전 중 운전자의 자동차 핸들의 회전각을 탐지하는 방법을 제안한다. 제안하는 시스템은 i) 스마트워치 위치 인식, ii) 운전자 인식, iii) 핸들의 회전각 계산, 3가지 단계로 구성되어 있다. 이를 위해, IMU 센서와 아두이노(Arduino)를 이용하여 웨어러블 디바이스의 시제품을 자체 제작하고 제안하는 시스템을 구현 하였다. 실험을 통해 핸들의 회전 방향을 높은 정확도로 계산할 수 있고 회전각 또한 평균 $11.77^{\circ}$의 낮은 오차를 보여 제안하는 시스템의 실효성을 입증하였다.

As wearable technology is becoming more common and a part of our lives, there have been many efforts to offer various smart services with wearable devices, such as motion recognition, safety of driving, and so on. In this paper, we present a method that exploits the 9-axis inertial sensors embedded in a smartwatch to identify whether the user is a vehicle driver or not and to estimate the steering wheel turning direction in the vehicle. The system consists of three components: (i) position recognition, (ii) driver recognition, and (iii) steering-wheel turning detection components. We have developed a prototype system for detecting user's motion with Arduino boards and IMU sensors. Our experiments show high accuracy in recognizing the driver and in estimating the wheel rotation angle. The average experimental error was $11.77^{\circ}$ which is small enough to perceiver the turning direction of steering-wheel.
