Sony is working on a visor-like personal 3D display known as the Headman, which enables game playing without the need for a TV - 3D or otherwise.
The firm's executive deputy president Hiroshi Yoshioka revealed he had been using the headset to play Gran Turismo 5. "Nobody - not even my wife - interrupted me, so I could get the highest score," he claimed at CES last night.
The device, which does not yet have a release date or price, contains two small displays, one per eye, and built-in earphones.
Focusing primarily on home electronics, Sony didn't have much more gaming news to reveal at its press conference, bar stating that the PlayStation Network now boasts 60 million sign-ups. The company did not reveal how many of these translated to active accounts.
Speculation that Sony might confirm the much-rumoured PlayStation phone at CES was left unrewarded, although CEO Kaz Hirai at one point hinted that the firm was "integrating into mobile the assets we've collected in the PlayStation family."
