Spatial motion pattern input system and input method

DETAILED DESCRIPTION Accordingly, the object of the present invention is to provide a spatial motion pattern input device which can recognize the operator's spatial motion pattern in space to control a computer or multimedia equipment according to the spatial motion pattern, or offer a sensuous man-machine interface environment, in an input system using a three-dimensional input device such as a spatial control mouse enabling pointer operation in any imaginary plane and even spatial pointer operation.
The foregoing object is accomplished by providing a spatial motion pattern input system for causing a control target device to perform control according to a spatial motion pattern of a spatial control input device, comprising: a move sensing section for sensing at least the amount of movements of the spatial control input device on two axes among the amount of movements of the device on three specific nonparallel axes in space; a conversion section for converting the amount of spatial movements composed of at least two amounts sensed at the move sensing section into a motion vector sequence; an identification section for performing identification by comparing a motion vector sequence corresponding to a basic motion pattern previously entered with the motion vector sequence; and an execution section for controlling the control target device on the basis of the recognition result from the identification section.
Preferably, the identification section contains: a unit vector processing section for generating a unit vector function on the basis of a motion vector sequence obtained from the amount of movement of the spatial control input device and/or an addition vector processing section for generating a cumulative vector function on the basis of a motion vector sequence obtained from the amount of movement of the spatial control input device; and an identification section for comparing the generated unit vector function with a unit vector function obtained from a motion vector sequence corresponding to a basic motion pattern and/or comparing the generated cumulative vector function with a cumulative vector function obtained from a motion vector sequence corresponding to a basic motion pattern, and then on the basis of these comparison results, identifying the spatial motion pattern of the spatial control input device
