Though there are several reasons for accidents to occur, one of the main reasons can be the drowsiness of the driver. Drowsiness and Weariness are amongst the significant causes of road accidents. This Book gives an insight into how we can detect the drowsiness of a driver. An alert will be sent to the driver as well as passengers on board if we detect that the driver is drowsy.
