Among all the recent talks of a new DS on the way, patent hawks have spotted a filing from Nintendo that appears to patent a force feedback-enabled stylus.
A source told CVG recently that DS 2 development kits are already in the hands of the Pokémon Company, but they couldn't reveal any specifics about the hardware.
Previous patents have already suggested motion control (iPhone style) and force feedback will be included, but this newly uncovered patent (via BMC) offers what could be the first proper hint as to what Nintendo has planned for its DS follow-up - a rumbling stylus. Here's a snippet of the patent:
"A game apparatus includes an LCD, and a touch panel is placed on a top surface of the LCD. A player instructs an enemy character displayed on the LCD by use of a stick to attack the enemy character. For example, in a case that the enemy character exists at a depth of a game screen, little damage is applied to the enemy character, and a weak vibration is applied to the game apparatus. Conversely, in a case that the enemy character exists at a front of the game screen, much damage is applied to the character, and a strong vibration is applied to the game apparatus. In either case, the vibrations are transmitted to the fingers or hands of the payer via the stick."
How's that sound to you?
