separate from the main screen -- perhaps even on its back like the rumored PSP2 -- and Sony's trying to patent a way to manipulate objects through the screen as well. Second, there's a lot of mumbo-jumbo about being able to "enhance" or "transform" the user interface in response to different forms of input, which seems to boil down to this: Sony's trying to get some multitouch up in there, especially pinch-to-zoom.
Last but not least, the company's looking to cordon off a section of touchscreen buttons, including a 'paste' command, and patent a "prediction engine" that would dynamically change the onscreen layout based on your past behavior. If most of these ideas sound more at home in a new tablet computer rather than a gaming handheld, then great minds think alike. Still, SCEA is Sony's gaming division -- forlorn Linux computing aside -- so consider us stumped for now.
