Document Type and Number:
WIPO Patent Application WO/2008/069241
Kind Code:
A1
Abstract:
A motion-sensing program performs motion sensing by using an output of a magnetic sensor
having at least two axes. The program includes: a process for judging whether motion
sensing is present according to an output from the magnetic sensor of particular two
axes when the magnetic sensor is rotated in a predetermined direction; and a process
for identifying the rotation direction is the motion sensing is present.
