当然都是人类的生命活动,无畏隐私
A team from MIT has developed a system that uses wireless radio signals to monitor a person’s movement and activities without the need to film them. Researchers from the Computer Science and Artificial Intelligence Lab (CSAIL) suggest the system could help caregivers keep tabs on vulnerable people while maintaining their privacy.
RF-Diary can generate text descriptions of a person’s activities and interactions with objects. As such, it can provide updates about a loved one’s day-to-day life to those who live far away from home, which could give them peace of mind about a parent’s wellbeing.
The CSAIL team has already used the system in hospitals and assisted living facilities to monitor people for issues including Parkinson’s, dementia and COVID-19. The researchers have improved the system, which uses deep machine learning. It can identify activities, such as sleeping, reading, cooking and watching TV, and items like laptops. RF-Diary is accurate in classifying more than 30 household activities over 90 percent of the time, according to the researchers.
