GamesIndustry: The controller. You showed off the boomerang, then said it was a prototype, and now you've come back and done the Dual Shock but with a twist - no pun intended. How long have you known that this was the plan?
Phil Harrison: The motion sensing controller has been thought about since about 1994, but in reality, you can't make some of the ideas that we have because the technology is not available in sufficient quantity or at a low enough price, and you kind of have to wait for certain things to converge. We had the concept of PlayStation Portable for many years before we could actually deliver it at a price and at a standard that was acceptable.
GI: The controller is obviously a surprise to the industry. We've been thinking about it for a while, but it's a relatively recent addition to the format. We didn't show it last year, because we weren't ready to. The boomerang, as you call it, was very clearly designed as a design concept, and was never intended to be the final controller, despite what everybody said about it.
PH: I think we certainly saw the strength of feeling that existed about the boomerang - even though nobody in the world ever held it in their hand. I thought that was very interesting, that people were criticising it for what it looked like, not how it felt.
GI: When you made the decision to put the tilt functions into the pad, how heavily influenced was that by the great response Nintendo has had to the same kind of technology in the Wii controller?
PH: I think that some of the research that we've done, clearly other companies have been doing as well - so there's nothing completely surprising about that. But I know that the strategy was to take what was already a winning formula - to have a controller as well regarded as it, and kind of the de facto industry standard that this PlayStation shape controller has become. If you include the ones that are packed in, the secondary ones and the knock-offs that are the same shape, there are probably around 400 million of these things that have been sold on PSone and PS2.
So, we kind of took an "if it ain't broke, don't fix it" strategy - but by adding motion sensitivity to the controller... Well, we didn't start the wave, but we've kind of jumped onto that wave. I'm quite happy to admit that, but that will be one of the defining characteristics of next-generation gaming, the complexity and sophistication of input that you can get from a very simple device.
