Scientists have developed an AI that uses WiFi to detect people behind walls and then model what the people are doing. It's believed this new tech will help the care for people with diseases like Alzheimer's or Parkinson's and older people living in assisted living facilities. It will sense how people are walking and whether they are starting to tremble and this data can be used to track the treatment of disease. However, I believe this tech is going to be used in hunter/killer drones and then modified for install into the T800, but that's just me. Check out the demo video. Watch the video here. Along with law enforcement applications, Katabi said the technology could be used for interactive gaming. But the team’s main focus is on healthcare applications, particularly for neurodegenerative diseases like Parkinson’s, Alzheimer’s, and Multiple Sclerosis.
