Abstract
A motion sensing program for executing a motion sensing based on at least a biaxial output of a magnetic sensor, which includes the steps of determining with respect to execution of the motion sensing based on the output of the specific biaxial output of the magnetic sensor upon its rotation in a predetermined direction, and identifying the rotating direction when execution of the motion sensing is determined.
Claims11
A method of motion sensing based on at least a biaxial output of a magnetic sensor, comprising the steps of:
- determining with respect to execution of the motion sensing based on a specific biaxial output of the magnetic sensor upon its rotation in a predetermined direction within a predetermined period of time;
- and
- identifying a rotating direction of the magnetic sensor when the execution of the motion sensing is determined,
- wherein in the step of determining with respect to execution of the motion sensing, the execution of the motion sensing is determined when a distance between a measurement starting point to a most distal measurement point from the measurement starting point in a coordinate of the specific biaxial output of the magnetic sensor is equal to or larger than a first predetermined value, and a distance between a measurement point resulting from substantially returning the magnetic sensor to a rotation starting position and the measurement starting point is equal to or smaller than a second predetermined value.

- determining with respect to execution of the motion sensing based on a specific biaxial output of the magnetic sensor upon its rotation in a predetermined direction within a predetermined period of time;
- and
- identifying a rotating direction of the magnetic sensor when the execution of the motion sensing is determined,
- wherein in the step of identifying the rotating direction, the rotating direction is identified based on a direction of a normal vector defined by a virtual line which connects a midpoint between a measurement starting point and the most distal measurement point to the measurement starting point, and a virtual line which connects the midpoint to the most distal measurement point.
