MENLO PARK, Calif. -- Facebook is testing a new system which tracks the on-screen habits of users.
The scale of the data collection would be unprecedented with Facebook now surpassing 1 billion users.
Facebook analytics chief Ken Rudin told the Wall Street Journal the system can track exactly where users' mouse cursors hover. It can also monitor how mobile users see their news feeds.
The system is only in its testing phase, Rudin said, and Facebook won’t make final decision on the technology until probably around the end of the year.
The data would primarily be used to improve targeted ads on the social media web site.
Users who are against the idea of Facebook using this technology to monitor on-screen habits can share their concerns online.
