Xbox 360 and DS motion controllers detailed

Motion-controlled gaming peripherals specialists Performance Design Products have unveiled two new controllers at GDC this week – a Wii Remote style stick for the Xbox 360 and a bizarre-looking chunky pen-style controller for the Nintendo DS.

TechRadar has been aware of the development of the Xbox 360's "Gametrak Freedom" ultrasonic 3D motion sensing tech for some time now, along with the first game that will work with the device, called Squeeballs.
