Commercial Solutions
The automobile industry has spent a significant amount of resources in recent
years to develop new features aimed at driver drowsiness detection. Moreover,
independent companies have also recognized that this market might grow and
become profitable and have developed products whose goals are comparable, but
work independently of the vehicle's brand or model. This chapter provides a
representative sample of those efforts.

Car Manufacturers
The ability to offer some type of 'driver assist' system as an added value to
their vehicle lineup has motivated many automobile manufacturers to offer built-in
solutions that are capable of detecting signs of driver drowsiness and warning
the driver accordingly. These are some examples (sorted alphabetically by car

position in the lane and estimate the driver's alertness level based upon driver
behavior, i.e, the ability to stay within the lane's limits. If the alertness level
is perceived to be lower than a certain threshold, a light audible and visual
warning—“Rest suggested”—appears in the car's instrument cluster; if it falls
even further, a more severe alert—“Rest now”—(with red light and chime sound)
is displayed until it is explicitly dismissed by the driver. The system also offers
