Spatial motion pattern input system and input method

A spatial control input device for sensing spatial motion patterns to cause a control target device to perform control according to a spatial motion pattern drawn by an operator, comprising:

• move sensing means for sensing at least an amount of movements of the spatial control input device on two axes from an amount of movements of the spatial control input device on three specific nonparallel axes in space, by means of an element built in the spatial control input device which operates in response to a change in velocity of the spatial control input device;
• conversion means for converting said amount of spatial movement of the spatial control input device on two axes into a first arbitrary direction motion vector sequence;
• identification means for performing identification by comparing a second arbitrary direction motion vector sequence, corresponding to a basic motion pattern which was previously entered, with said first arbitrary direction motion vector sequence;
• and
• transmission means for transmitting a recognition result from said identification means to the control target device.

A spatial motion pattern input method for causing a control target device to perform control according to spatial motion patterns of a spatial control input device, the method comprising the steps of:

• sensing at least an amount of movement of the spatial control input device on two axes from an amount of movement of the spatial control input device on three specific nonparallel axes in space, by means of an element built in the spatial control input device which operates in response to a change in velocity of the spatial control input device;
• converting said amount of movement of the spatial control input device on two axes, sensed at said move sensing means, into a first arbitrary direction motion vector sequence;
• comparing a second arbitrary direction motion vector sequence, corresponding to a basic motion pattern previously entered, with said first arbitrary direction motion vector sequence;
• and
• controlling said control target device based on a result of said comparing step.
