Online gaming publication Games Beat has revealed that Sony issued a Wii U like patent during 2010. The patent is Titled Position-Dependent Gaming 3-D controller, and Handheld as a Remote. Here’s a brief description of the intriguing patent which bears a striking resemblance to what Nintendo has proposed with Wii U:
Methods and systems for using a position of a mobile device with an integrated display as an input to a video game or other presentation are presented. Embodiments include rendering an avatar on a mobile device such that it appears to overlay a competing user in the real world. Using the mobile device’s position, view direction, and the other user’s mobile device position, an avatar (or vehicle, etc.) is depicted at an apparently inertially stabilized location of the other user’s mobile device or body. Some embodiments may estimate the other user’s head and body positions and angles and reflect them in the avatar’s gestures.
