The U.S. Patent and Trademark Office has published a patent application on April 10 by Microsoft for a gyroscopic-based input device for use on computers and games consoles such as the Xbox 360. According to the application: Described is a technology by which a computer pointing device (generally a mouse but alternatively a game controller or remote control device) may be worn on the hand and operated without needing to contact a mousing surface. The controller is apparently still at the research and design stage and it is unclear if it will ever be released. Check the forums for a more detailed description from a source at TXB.
We were told that the motion sensing controller that Microsoft was researching had the functionality of both the Nintendo Wii Remote and the Nunchuk packed into a single device, with a shape that is neither that of a banana, nor a remote controller, but more like a “pistol grip.” On top, it is supposed to have an analog stick (that could be replaced by a trackball) surrounded by the four action buttons.
