A new technology has been developed by Massachusetts Institute of Technology’s (MIT) scientists of artificial intelligence and computer science lab which uses RF waves to detect the human’s location and recreate the body structure in stick design. It tracks body activities and recreate posture of someone’s body while siting, standing, walking, sleeping, etc.
Neural network has been used by the scientists of MIT to examine radio signals that bounce off people’s bodies. The network has been trained with a video of a human walking next to the RF interference as RF signals appear everywhere and is easier to use than other sensors. The system wasn’t trained to see through walls, it only ‘generalizes its knowledge to handle through-wall movement.’
Diseases like Parkinson’s and Multiple Sclerosis (MS) could be analyzed with the help of this new technology and helps doctors to prescribe medications accordingly. It also provides additional security to elderly people by observing injuries, changes in activity due to health issues, etc.
According to researchers report, “All data the team collected has subjects’ consent and is anonymized and encrypted to protect user privacy. For future real-world applications, the team plans to implement a ‘consent mechanism’ in which the person who installs the device is cued to do a specific set of movements in order for it to begin to monitor the environment.”
The new technology has been introduced for healthcare section, emphasizing on health issues by keeping an eye on patients without using camera-like instruments.
Antonio Torralba, Professor and researcher of MIT said, “If you think of the computer vision system as the teacher, this is a truly fascinating example of the student outperforming the teacher.”
