Facebook owns plenty of other apps and services — including the Oculus virtual reality platform, which (like all VR platforms) collects incredibly detailed information about where users are looking and how they’re moving. VR headsets have a clear potential for surveillance and data harvesting, and Facebook has a bad track record regarding protecting privacy. So what exactly is the link between Oculus and Facebook as far as user privacy is concerned? >A VR platform like Oculus offers lots of data points that could be turned into a detailed user profile. Facebook already records a “heatmap” of viewer data for 360-degree videos, for instance, flagging which parts of a video people find most interesting. If it decided to track VR users at a more detailed level, it could do something like track overall movement patterns with hand controllers, then guess whether someone is sick or tired on a particular day. Oculus imagines people using its headsets the way they use phones and computers today, which would let it track all kinds of private communications.
