NEW YORK—For PlayStation 3 fans who want to do more than mash buttons when playing games on the console, Sony Corp. is introducing a wireless keypad that can be attached to the system’s controller for typing and Web browsing.

The Bluetooth-enabled keypad, available in November, is intended to make it easier to chat during multiplayer games. Currently players talk to each other over headsets with microphones. Gamers tired of hearing inane banter from their peers may welcome the ability to put down their earpieces and communicate through typing instead.

Another feature is a button on the keypad that will let users turn it into a touch pad and use the entire surface as a mouse by sliding their finger over the surface. This, Sony says, will make it easier to browse the Web using the console.

There is already a wireless “ThumbPad” ($30) available for the PS3 from Mad Catz Inc., but this is a first from Sony itself. Sony has not yet announced a price.
