"Data from a personal device — a smartphone or smartwatch — is also sensitive, raising issues of data use and privacy, which complicates the collection of sensor data.

The development of software models using mobile sensor data has been hindered, said Deborah Estrin, a professor of computer science at Cornell Tech, because of “the absence of labeled data sets. And the reason for that is the lack of a community effort to do that in an ethical, efficient way.”

Ms. Estrin is one of several computer scientists from universities around the world who are advisers to CrowdSignals, as are researchers at companies like Microsoft and Intel."
