The DualShock 3 Wireless Controller (SCPH-98050/CECHZC2) is a gamepad for the PlayStation 3 that incorporates the design and features of the Sixaxis wireless controller with the haptic feedback capabilities of the DualShock and DualShock 2. The vibration function on the DualShock 3 does not interfere with the motion sensing function of the controller and both functions can be used at once. Like the Sixaxis, it is a wireless controller that uses both analog and digital signals simultaneously at all times and has a USB mini-B port for charging, as well as for playing while charging. It can also be used on a PSP Go via Bluetooth, but the controller and the PSP Go must be registered using a PS3.
