Sony Computer Entertainment Worldwide Studios president Shuhei Yoshida told VentureBeat that virtual reality technology is in its infancy and that the experiments both companies are doing are of great benefit to each other and the technology overall.
"Even though we don't work with each other directly, we're helping each other as far as announcing something or showing a proof of concept or publishing some documents or something like that," he said.
"We are still really trying to define or discover what works and what's required for the hardware tech. Our team feels that we're getting closer, but there are certain things that still have to be improved to make a good consumer product. The Oculus guys are saying the same thing. Even their DK2 [development kit 2] is pretty good, but still, they see some other areas they still have to work on.
"So in trying these things, we are kind of helping each other. For example, DK2 has low persistence. It's pretty good. We don't have that. What we have is the 3D audio worked out ... how we're going to mix that and make it much easier, more comfortable to wear, for the PlayStation Move interaction that's integrated with the headset. The positional tracking."
Yoshida went on to say that sharing knowledge between the two companies is vital to solving many of the hurdles VR faces.
"We're pushing different things," he explained. "Like everything in engineering, once someone does it, it's common knowledge. Engineers, when they see that another person has done it, that elevates their perspective to push further. At this stage, we're helping each other and trying to find solutions to a lot of problems that we're trying to solve."
Sony officially revealed its PS4 virtual reality headset at GDC in March. In development for three years, it currently features a five inch LCD screen, a 90 degrees field of view, an accelerometer, a gyroscope and 3D audio support.
