Sony is not at all a stranger to patenting video game console-compatible controllers and devices. Over the past few months, several designs were unearthed at the official website of U.S. Patent and Trademark Office.

While this does not guarantee anything, it's amazing to know that Sony seems preparing for the future of the video game industry. What we have here are several bio-feedback devices which are far more complicated than the "handheld computer interactive device" that we shared with you before.

We read through almost the whole thing (via our Read link below) and if we are not mistaken, the bio-feedback devices are being controlled by some sort of a headset. Several peripherals can then be attached to this headset.

One statement from the patent reads, "One or more bio-feedback devices for transmitting to a video game system physiological data of a participant". The said devices include more sensitive buttons, wearable motion-sensing as well as voice recognition.

We have no idea when these patents will become a reality. But if you ask us, our wish for now is much more simpler than this - a rumbling SIXAXIS at this year's Tokyo Game Show.
