Nikkei Net reports via its "Tech On" technology site that Sony Computer Entertainment has filed for a patent which could end up being an answer to Nintendo's Wii controller.
The patent describes a technology for reading three-dimensional positional and directional information for an input device using a single two-dimensional camera. The patent specifically states that this technology could be used to control action in a videogame. It even goes so far as to suggest a use as an alternative for a joystick when creating game interfaces.
According to Nikkei, the special feature of the Sony technology is that it manages to grab 3D information about an object using a single camera rather than a pair of cameras.
Sony filed for the patent on December 5, 2005, Nikkei reports, but the information was made public only on the sixth of July. The following image was included as part of the filing.
E3 saw the unveiling of two motion-sensing PS3 products from Sony. The system's controller was shown for the first time with motion sensors, allowing it to detect limited motion. Additionally, Sony demonstrated its next-generation EyeToy camera, using the device to recognize player-manipulated cards as part of a card-based RPG.
Presumably, if the technology mentioned in this patent becomes a part of the PlayStation 3, it would be through the EyeToy.
