Ricebrans are software-based sensors used to collect data from objects around a room, but they have a history of being abused.
The sensor has been used to record people’s movements in the house, and to collect body temperature.
This month, a Brazilian man died in his home from hypothermia, after Ricebrains found him asleep on a couch in his apartment.
The project is part of Google’s effort to better understand what it calls “the human microbiome,” which is a collection of bacteria, fungi, viruses and other organisms that live in the human body.
Google said it plans to use the data it collects to improve its mapping software, the Street View feature of Google Maps, and other products.
The company has also announced plans to make Ricebranes available to researchers for their research.
