The patent I've seen referenced is this one: https://patents.google.com/patent/US10912502B2/en https://patents.google.com/patent/US10912502B2/en It seems to be a combination of describing an arrangement of sensors, strapping those sensors onto someone, and having the strapped-thing be a touchscreen device with wireless comms. As a layperson it does sound like one of those patents which we like to make fun of -- the "X but with a computer" ones that're conceptually incredibly obvious. That said, I don't know if the sensor arrangement they describe is actually a novel thing that wasn't already out-of-patent elsewhere.
