A recent patent filed by Sony Computer Entertainment Inc. has revealed what are believed to be some attachments for Sony's upcoming Motion Controller Wand PS3 accessory.
To quote: "The patent for an "Expandable Control Device Via Hardware Attachment" touches on a number of control options. According to details from the patent, Sony's motion controller may offer the option to join two motion control units together lengthwise or in an H-shape.
And as pictured above, a unique, secondary controller attachment may offer a solution to the one DualShock in one hand, one motion controller in the other hand scheme seen at Sony's Tokyo Game Show press conference.
Other potentially interesting add-on possibilities are attachments shaped like a baseball bat, a the business end of a flashlight and a rattle-like sphere that's very maraca like.
Perhaps more interesting is a proposed biometric reader attachment, including a "thumb reader used to validate the identity of the person holding the controller by analyzing the biometric data provided by the attachment."
Additional possibilities included microphone attachments and swappable control faceplates-letting the player customize whether a motion controller has buttons or a d-pad or even a dial."
