Driver inattention assessment has become a very active field in intelligent
transportation systems. Based on active sensor Kinect and computer vision
tools, we have built an efficient module for detecting driver distraction and
recognizing the type of distraction. Based on color and depth map data from the
Kinect, our system is composed of four sub-modules. We call them eye behavior
(detecting gaze and blinking), arm position (is the right arm up, down, right
of forward), head orientation, and facial expressions. Each module produces
relevant information for assessing driver inattention. They are merged together
later on using two different classification strategies: AdaBoost classifier and
Hidden Markov Model. Evaluation is done using a driving simulator and 8 drivers
of different gender, age and nationality for a total of more than 8 hours of
recording. Qualitative and quantitative results show strong and accurate
detection and recognition capacity (85% accuracy for the type of distraction
and 90% for distraction detection). Moreover, each module is obtained
independently and could be used for other types of inference, such as fatigue
detection, and could be implemented for real cars systems.

基于 Kinect 和计算机视觉技术，构建了一个有效的模块，用于检测驾驶员注意力分散和识别分散类型，每个子模块独立获得并可用于其他类型的推理，如疲劳检测，并可用于实际汽车系统。
