The head of Sony Computer Entertainment believes that automatic stereoscopic 3D technology (S3D)  employed by Nintendo for 3DS game console will not work in a long term. Sony conducted the appropriate research back in the past and did not find the technology – which Sony calls naked eye 3D – flawless.

“Based on internally conducted research, naked-eye 3D for portables does not have high precision, and at present there are limitations,” said Kazuo Hirai, the head of SCE, reports Edge-Online web-site.

Sony itself is trying hard to promote stereo-3D technologies so that to sell its PlayStation 3 game console along with its latest Bravia televisions which support S3D technology. Still, the company has not announced plans to update its PlayStation Portable console with an S3D screen due to the aforementioned concerns.

It is noteworthy that Nintendo itself admits that the technology featuring stereo-3D screen on the 3DS is not suitable for large screen HDTVs.

“With this parallax barrier technology, the LCD must be a certain distance away from the screen. It also needs a certain viewing angle. We think it is not a great match for the home TV set. As one of the engineers, I can anticipate that someone will invent a 3D TV that does not require you to wear 3D glasses. As far as today is concerned I do not think they can do it well. We need an invention to make it happen. If you ask me when, I have no idea,” said Satoru Iwata, chief executive officer of Nintendo.
