Researchers develop face 'e-tattoo' to track mental workload in high-stress jobs

New wireless forehead e-tattoo measures EEG and EOG signals to monitor cognitive fatigue and performance

Scientists say that they have formulated a way to help people in stressful and demanding work environments track their brainwaves and brain usage — an electronic tattoo device, or "e-tattoo," on the person's face.

In a study posted in the science journal Device, the team of researchers wrote that they found e-tattoos to be a more cost-effective and simpler way to track one’s mental workload.

Dr. Nanshu Lu, the senior author of the research from the University of Texas at Austin, wrote that mental workload is a critical factor in human-in-the-loop systems, directly influencing cognitive performance and decision-making.

Lu told Fox News Digital in an email that this device was motivated by high-demand, high-stake jobs such as pilots, air traffic controllers, doctors and emergency dispatchers.

Lu also said ER doctors and robot/drone operators can also leverage this technology for training and performance enhancements. 

One of the goals of this study was to find a way to measure cognitive fatigue in high leverage and mentally straining careers.

The e-tattoo is temporarily attached to the subject's forehead, and is smaller than current devices in use today.

According to the study, the device works by using electroencephalogram (EEG) and electrooculogram (EOG) to measure both brain waves and eye movements.

While most EEG and EOG machines are bulky and expensive, the e-tattoo offers a compact and cost-effective solution.

Lu wrote that in this study, "we propose a wireless forehead EEG and EOG sensor designed to be as thin and conformable to the skin as a temporary tattoo sticker, which is referred to as a forehead e-tattoo."

Lu also added that "human mental workload is a crucial factor in the fields of human-machine interaction and ergonomics due to its direct impact on human cognitive performance."

The way the study was conducted was with six participants being shown a screen on which 20 letters flashed up, one at a time, at various locations. 

The team found that as the tasks became harder, the different types of brainwaves detected showed shifts in activity that corresponded to a higher mental workload response. (iStock)

Participants were asked to click a mouse if either the letter itself, or its location, matched one shown a given number of letters.

Each participant carried out the task multiple times, corresponding to four levels of difficulty.

The team found that as the tasks became harder, the different types of brainwaves detected showed shifts in activity that corresponded to a higher mental workload response.

The device consists of a battery pack and reusable chips with a disposable sensor.

Lu said that the device is currently a lab prototype.

"Before it can be ready for commercialization, it will need more development, such as real-time, on-tattoo mental workload decoding and validation on more people and in more realistic environments," she said. "The prototype currently costs $200."

When I get stressed, fatigued, brain fuzz and just plain tired, I don't need a gadget to let me know.
My God created body lets me know.  Nap time.

Now, what about that frog. (Dead)frogs should be roasted or BBQ'ed. Never boiled.

What does the devil have to do with frogs.
The frog will jump out of the water pot as it becomes hot, by the way.

I know, he puts a lid on it...

Thanks Orion...

Yes, Sower. It is a common saying that if you put a frog in cool water, it will  fall asleep as the water slowly heats until it boils, killing the frog.  While this saying might not be scientifically accurate, it is used to illustrate the gullible nature of man, who is all too ready to believe something simply because it sounds utilitarian, all the while it is part of the devil's grand scheme of deceiving and charming man. 

It will not be long before society has become so comfortable with e-tatoos for other things, that we read about, or are ordered to sign-up and receive your very own e-tatoo in order to buy and sell. 

Peace
