Reeves, a professor at Stanford University, and two colleagues announced the launch of the Human Screenome Project today in Nature. The project aims to more accurately capture our digital footprint using an eyebrow-raising technique: background software that screenshots a volunteer’s phone every five seconds while it’s activated. The idea is that just as the Human Genome Project and genomics changed our understanding of diseases, big data could give us a better idea of how technology is linked with social problems.
