Researchers led by Massachusetts Institute of Technology professor Dina Katabi developed software that analyzes variations in radio signals to identify the silhouettes of people on the other side of a wall and track their movements. Researchers say the technology will assist health-care providers and help families keep track of the elderly and toddlers. Law enforcement and the military could also use the tool.
"Think of it just like cameras, except that it's not a camera," MIT researcher Fadel Adib told Phys.org. "It's a sensor that can monitor people and allow you to control devices just by pointing at them."
Research began in 2012, and researchers now expect to release a commercial device, through a company called Emerald, for around $300 early 2017.
