An executive from virtual reality company Oculus says consumers shouldn't be concerned about an invasion of their privacy when using the Oculus Rift. Jason Rubin, Oculus' head of worldwide studios, is downplaying questions raised about the VR system's privacy policy.Sen. Al Franken (D-Minn.) wrote an open letter to Oculus CEO Brendan Iribe earlier this month asking for details about user data collected by the new VR system, which is worn on users' heads and can detect movement, location and sound. "We're going to answer all of that in due time," said Rubin, a video game industry veteran who joined Oculus in 2014."We're absolutely confident that people are going to say, 'Oh. Yeah. Right.'" The Oculus Rift began shipping to consumers March 28. It costs $599 and features a headset with a microphone and a pair of high-definition screens capable of broadcasting images when connected to a high-powered PC.
