A newly discovered Sony patent application reveals a device that literally sticks together the functionality of the PlayStation Move and its Navigation Controller with the form factor of the DualShock. The "Hybrid Separable Motion Controller," filed last May, consists of two halves of a standard DualShock shape, each with a Move-style orb at the top.
Both sides have accelerometers, gyroscopes, and magnetometers to sense motion, and can be operated either separately or locked together into one unit. It's designed such that games will be able to detect the configuration in use.
We're asking Sony if the company intends to use this concept in the PS3 or future devices.
