A driver assistance system (DAS) should support the driver by monitoring road and vehicle events and presenting relevant and timely information to the driver. It is impossible to know what a driver is thinking, but the driver’s gaze direction can be monitored and compared with the position of information in the driver’s viewfield to make inferences. In this way, not only the driver’s actions are monitored, the driver’s observations are monitored as well. In this paper the automated detection and recognition of road signs are presented, combined with the monitoring of the driver’s response. A complete system is presented that reads speed signs in real-time, compares the driver’s gaze, and provides immediate feedback if it appears the sign has been missed by the driver.
