Seeing Machines is an award-winning technology company focused on designing vision-based human machine interfaces, including the Driver State Sensor (DSS) a robust, automatic sensor platform that uses cutting-edge face tracking techniques to deliver information on operator fatigue and operator distraction.

Driver State Sensor for fatigue management

No matter the industry, the human brain responds in the same way when subjected to long shifts, night driving, disrupted or reduced sleep and rapidly changing schedules.
The brain becomes tired and begins to slowly fade – resulting in driver performance levels that fall away predictably.

Continuous operations and the 24/7 pace of the global economy is here to stay. Keeping humans to such schedules is a difficult and sometimes dangerous task, primarily because driver fatigue in the cab has until now been a big unknown. When and how rapidly do driver performance levels drop? Without an understanding of the driver, the only tool we have is guess-work.

Stop guessing with the Driver State Sensor (DSS) from Seeing Machines: know how fatigue affects drivers, understand why critical events occur, prevent accidents before they happen. The DSS delivers this critical information through its revolutionary face tracking technology.

The DSS measures the driver’s eyelid opening, and uses this data to determine the presence or onset of fatigue. It also measures head orientation, providing information on distraction. The driver does not carry or wear any cumbersome equipment, the DSS is installed in the vehicle – not on the driver. The DSS operates invisibly to the driver, and does not change or impact the driving task in any way.

Automatic driver fatigue and distraction monitoring

With its dashboard mounted sensor, the DSS “sees” the driver’s face and measures the amount of eyelid closure and orientation of the driver’s head. Eyelid closure information is processed to determine the level of driver fatigue, and by tracking head movement, the DSS is able to detect driver distraction.

Once installed in the vehicle, the DSS is fully automatic. There is no calibration procedure for new drivers, and slip-seat operations are handled transparently. Any driver can get behind the wheel without a time consuming setup process, annoying sensor attachment, or any special knowledge about the system. There is no disruption to work processes and no additional driver training required.

Fatigue warning system

The DSS, once deployed, can raise the driver’s awareness of fatigue and distraction. Instant audio feedback is available to drivers when fatigue or distraction events are detected, but fatigue warnings are modulated such that the system cannot be abused to stay awake. Raising the awareness of fatigue and distraction through driver feedback promotes recognition of the value of sleep and which will help to reduce incidents across an organization.

Fleet management integration

In addition to in-cab feedback, the DSS can be integrated into fleet management. The data relating to fatigue and distraction events can be stored for later analysis, or critical data can be sent directly via GPRS or satellite to provide real-time information to fleet management. Event reporting allows managers to pinpoint issues within the fleet and address these specifically.

Benefits of advanced fatigue management

There are numerous benefits from employing DSS advanced fatigue management beyond in-cabin alarms, including:

Understand the current baseline level of fatigue in your fleet
Better manage driver scheduling
Detect changes in the organisation which affect driver fatigue levels
Increase awareness of fatigue as a key issue
Reduce fatigue related crashes
