United States Patent and Trademark Office (USPTO) issued a very broad patent on "Method and apparatus for controlling a computer system ". According to the authors, patented method “facilitates an intuitive motion control of the application by physically manipulating the electronic device…it enables a user to intuitively control the state and/or displayed content of a computing device without the conventional need of pressing button(s), or manipulating a trackpad, trackball, etc. In this regard, the motion control agent represents a new paradigm in user control of computing systems.”
So handheld devices like iPhones and Androids might be covered. But I always wonder about these patents.
There is a lively conversation going on at Slashdot where they say it is a narrow patent.
