LED technology, which is a more cost- effective solution that offers fewer features – or the pixel technology, which is higher-end. And we’re the only one on the market right now who can really develop both chip technologies and can offer them to customers.” When asked about how the technology
could deal with the subjectivity of what a driver ‘distraction’ is, Wittman said: “We use very sophisticated algorithms. We work together with a Swedish company called Smart Eye, which is also part of the demonstrator we were building. “Te algorithm is very important.
Te algorithm shouldn’t have false detection, otherwise people are just going to turn it off.” Indeed, one challenge with DMS is
that drivers may find it invasive or even frustrating, and thereby be reluctant to use it. Talking about how a driver would be
notified, Wittman said: “It’s an audio-visual alert with visible LEDs. For example, the dashboard could turn red to say, ‘Hey, eyes on the road, please!’ Tere will also be vibrations on the steering wheel.” Ams Osram also released a proof-of- concept last year called Icarus, which aims to upgrade DMS designs to include features such as an augmented reality head-up
display, secure driver authentication, and advanced drowsiness detection. Te Icarus system accurately measures the position of the driver’s eyes and head pose in 3D using a depth map, Ams Osram says, and supports software that can detect micro-

sleeps, alongside other signs of drowsiness. Te same technology could also one day be used to support online shopping features for passengers riding in the back of future autonomous vehicles. “We built a 3D sensing demo that has more functionalities, such as identifying a person to authorise a payment, for example while shopping on Amazon,” said Wittman. One of the biggest hurdles for DMS
manufacturers is cost. Te systems can be expensive to install and maintain, which makes rolling them out commercially a challenge. Tat’s why companies such as Ams Osram are developing compact, cost- effective models. “You really want to hide [the DMS],”
Wittmann says. “Everything needs to look super slick. You don’t want to necessarily tell the drivers ‘Oh, there is a camera sensor monitoring you all the time’. Terefore, the component size is very important. Tis latest generation is very compact and very powerful.”
