SCEE R&D boss Paul Holman told Edge at Develop this week that PS3's upcoming motion technology will cause advancement in games thanks to its precision.
"I think we can just say that it’s very, very precise," he said. "People are going to be able to take games in this space forward because of the precision aspects."
Kish Hirani, head of dev services, gave an example.
"The classic example I give to people is that the most precise thing you can do is write your name using a [piece of] chalk on a blackboard," he said.
"Try doing that with a mouse and it’s bloody difficult."
More through there. Sony showed the tech in action at the UK conference yesterday.
