Researchers from the University of Chicago and Sony are developing a wearable electrical muscle stimulation system that boosts your physical reaction time without making it feel like you've lost control of your body. The latter is particularly important when considering the development of exoskeletons and other systems that bring us physically closer to machines for augmenting human capabilities. The system essentially zaps your muscles into contracting at precisely the right time while making it seem as if you're still controlling the movement. From IEEE Spectrum:
The typical reaction time for a human is about 250 milliseconds—meaning it takes you about a quarter of a second after you see something to physically react to it. But the researchers explain that "our conscious awareness of intention takes a moment to arise, around 200 ms." In other words, it takes you about 200 milliseconds for your brain to turn sensory input into a decision to do something like move a muscle, and then another 50 or so milliseconds for that muscle to actually start moving. The researchers suggest that this 50-ish millisecond gap between intention and action is a window that they can exploit to make humans react more quickly while still feeling like the action they take is under their control.
The video below shows a series of experiments that demonstrate how reflexes can be usefully accelerated without decreasing the sense of control, or agency, that the user experiences. It turns out that an EMS-driven improvement in reflexes of up to 80 milliseconds is possible while still maintaining the user's sense of agency, which is the difference between success and failure in these particular experiments.

WordPress is a fantastic tool for building web pages – if you know how to use it. Even with all the accessibility, a lot of the deeper features of WordPress are lost in translation to the average user. Enter WP Page Builder, a tool that not only makes WordPress site design easy but also more […]
In this age of ever-shrinking gadgets, it bears reminding that sometimes bigger is actually better. And if you care about audio quality, we can’t think of a better example of this principle than these TREBLAB Z2 Bluetooth 5.0 Noise-Cancelling Headphones. We know tiny Bluetooth earbuds are all the rage right now. But their battery life […]
In this Instagram age, pictures aren’t just worth a thousand words; they can be worth a pretty penny, too, which makes graphic designers a highly sought-after profession. But being a graphic artist takes more than just the ability to draw a picture, and certainly more than the ability to navigate through Photoshop. The School of […]
