This post (https://lnkd.in/dPfnQBaS) includes a video of #DMS from Seeing Machines. I grabbed the frame shown below to help with this explanation.
Early generation DMS gathered "raw data" such as head pose estimation (X,Y,Z) eyelid opening (a measure known as "PERCLOS" or percentage closure), and eye blinks. More recently, eye-gaze vector measurement (x,y,z) has also been possible, but is much more challenging and requires more computational resource. Frame rate has moved from 30fps to 60fps, with imager resolution moving from about 1 megapixel (MP) to 2MP. Occupant monitoring (OMS) is starting to move the imager resolution to 5MP.
The picture below shows the evolution of DMS from "raw data gathering" to "high level signals". The two signals shown are "DDE" or Driver Distraction Event and "DAS" or Driver Attention State. The high level signal classifiers tell us the driver is not distracted (by cellphone or the navigation system, say) and has had eyes on road continuously for 22.4 seconds.
Going from raw data gathering to actionable high level signals is the work of human factors and behavioral research and creates a model of parameters measuring visual distraction, cognitive distraction, drowsiness, attention state and impairment. In future, those signals can be used by an automaker to vary the sensitivity and performance of the braking and steering ADAS in real-time. In this example, the driver is not distracted and has eyes on road, so the "nag" on the lane-keep system can be temporarily turned off. The outcome? You clip the white lane markings in the road, no annyoing and distracting beeps.
There's more. Why is Qualcomm buying Veoneer? To own the perception stack and driving policy software developed by Arriver. Together with DMS from Seeing Machines, Qualcomm will have an automated driving and driver monitoring solution to offer to automakers that directly rivals Mobileye and Nvidia for Level 1 to Level 2+. This is where the battle for the #automotive market is playing out among the Silicon Valley tech giants, not in AVs, lidar and "self-driving".
If you are an investor and seek a deep dive on DMS technology and independent analysis of the potential for the leading DMS suppliers (Cipia, Jungo, Seeing Machines, Smart Eye and Xperi), I can be booked for telephone-based consultancy via GLG and Guidepoint. Just ask for me by name.
