DSS | Seeing Machines
The DSS-IVS (in vehicle system) measures the eyelid opening of the driver, and based on this data derives the drowsiness state. No sensors need to be worn by the driver; a remote sensor on the dashboard observes the face of the driver and measures eyelid closure. There is also no calibration procedure required for new drivers. This means any driver can get behind the wheel without any time consuming calibration, annoying sensor attachment process, or any special knowledge about the system.
