In the automotive sector, some engineering teams have developed driver monitoring systems (DMSs) that attempt to detect the driver yawning as a proxy for drowsiness. This is not only ineffective, but likely increases the risk of an accident due to drowsiness. Yawning is commonly associated with someone being tired or bored. However, recent research tells...
This year, I have spoken with key decision makers in nearly every major automaker and driver monitoring system (DMS) supplier. Within our team at Optalert, we have a very clear position on driver monitoring: If a driver is objectively impaired (whether by drowsiness, intoxication, or anything else), there must be an intervention. If they are...
From mid-2024, all new models of passenger vehicles in Europe require a driver monitoring system (DMS) that can detect drowsiness. Engineering teams across the automotive industry have scrambled to learn about the science of drowsiness and develop systems that can detect it in drivers. Each of these systems then needs to be validated and shown...
For the last decade Optalert’s focus has been driver drowsiness. We are now turning our attention to other health conditions and have developed an AI-based model that tests for obstructive sleep apnoea (OSA). The condition affects 13.2% of the world’s population and it is chronically underdiagnosed: 80% of people with OSA never undergo diagnosis or...
From mid-2024, all new models of passenger vehicles in Europe require a driver monitoring system (DMS) that can detect drowsiness. Engineers across the automotive industry have generally used one of three ground truths to measure drowsiness in drivers. Ground truth Description  JDS  Johns Drowsiness Scale Eyelid movements are a window into the cognitive state of...
Introduction Artificial intelligence (AI) is a hot topic. Amid all the noise about generative AI tools like ChatGPT and MidJourney, the myriad of other powerful AI applications has been drowned out. One such shift we foresee is that of health monitoring via the PC webcam. Enabled by increasingly powerful graphical processing units (GPUs) and tensor...
How can a remote mine site transmit data without wireless connectivity? We faced a unique difficulty: How could we transmit data on a remote mine site where there was no Wi-Fi or cellular coverage? Our team developed a novel solution that transmits real-time data over radio packet network. Given the low footprint of our system...
Drivers moving from 8-hour to 12-hour shifts were less drowsy! A large Brazilian mine evaluated the outcome of changing its truck drivers from working 8-hour shifts to 12-hour shifts. Optalert analysed the data from its fatigue management solution to assess the impact on driver drowsiness. Read on to learn how we reduced risk by 40%...
Imagine if automotive regulation allowed seat belts to unlatch or airbags to fail to deploy in over half of severe collisions. And legislators were dragging their feet on raising the minimum standard for fault tolerance. In such a scenario, who should fix the problem? Thankfully seatbelts and airbags are mature, well understood technologies, and the...
Optalert’s Johns Drowsiness Scale (JDS) accurately quantifies impairment caused by drowsiness, surpassing competing technologies in predictive power. This post outlines how Optalert has been able to quantify the relative risk of a driver’s impairment from drowsiness with a unique biomarker. It is independent of age, gender, or ethnicity. These claims are substantiated through both internal...
