MIT’s “RF-Diary” technology can help keep residents safe, and maintain privacy in communal care facilities. It can also keep an eye on older people living at home alone.
“The system, which is dubbed “RF-Diary” by the research team that created it, can identify whether a person is sleeping, reading, cooking, watching TV or more, by combining a map of a person’s living space with the types of activities that happen in different activities. The research team behind it trained the system on wireless signals generated by people performing known activities in these spaces, and was subsequently able to categorize activities from new people, in entirely new locations using the knowledge it gained through training.”
