A control information input method and system for an intelligent terminal

The present invention relates to an intelligent terminal control information input method and system, the method for three-dimensional control information input events are movable in three-dimensional space into a two-dimensional control information to control information of the intelligent terminal by a specific two-dimensional information operation, the method comprising the following steps: step triaxial acceleration sensor and a triaxial angular acceleration sensor sensing information acquired control information for the input terminal, and said rotation angle sensing information comprising initial value input terminals a0, b0 and c0, at any time, and the rotation angle value of the terminal a1, b1 and c1, and the above angle values ​​are determined based on the set three-dimensional coordinate system; for a difference between the rotational angle values ​​of the two moments of the acquired coordinate system conversion, and thus obtain the difference in the two-dimensional coordinates x and y coordinate system is set; dimensional coordinate values ​​(x, y) as the control for the acquired input information to the intelligent terminal, thereby controlling intelligent terminal behavior.
