The Ohio-based Impulse Technology has sued Microsoft,
claiming that the motion-sensing Kinect hardware for Xbox 360 violates
seven of its patents relating to tracking users' movements for the
purpose of playing video games without a controller.
Impulse's patents in question describe a "system and method for tracking
and assessing movement skills in multidimensional space," and an
"education system challenging a subject’s physiologic and kinesthetic
systems to synergistically enhance cognitive function," reports Patent Arcade.
Impulse says that it had notified Microsoft of these patents previously,
telling the company that the patents covered a "wide variety of games
where the movement of a player is tracked in three dimensions ... and
certain exercise games where the motion of the player is tracked to
effect movement of a virtual avatar, and the exertion of the user is
monitored, including where the tracking of the player is done by use of a
camera."
The company claims that Microsoft is willfully infringing on these
patents, and Impulse now seeks a permanent injunction, damages,
interest, attorney's fees and costs.
Impulse also named eight Kinect game developers, including EA, Sega, and
Konami, as defendants in the case, accusing them of making, selling and
importing into the U.S. games that infringe on its patents.
