Operation input system, control apparatus, handheld apparatus, and operation input method
First Claim
1. An operation input system that includes a casing and a motion sensor for detecting a movement of the casing inside the casing and calculates a position of the casing in a predetermined space based on an output of the motion sensor, the operation input system comprising:
- a position sensor configured to directly detect the position of the casing in the predetermined space;
correction circuitry configured to correct the output of the motion sensor using an output of the position sensor;
switch circuitry configured to switch on/off the output of the motion sensor; and
coordinate reference change circuitry configured to change one of a reference of spatial coordinates of the position sensor and a reference of spatial coordinates of the motion sensor using a difference between a first position of the casing calculated right before the output of the motion sensor is switched off by the switch circuitry and a second position of the casing calculated right after the output of the motion sensor is switched on by the switch circuitry.

Abstract
An operation input system includes a casing and a motion sensor for detecting a movement of the casing inside the casing and calculates a position of the casing in a predetermined space based on an output of the motion sensor. The operation input system includes a position sensor and a correction section. The position sensor directly detects the position of the casing in the predetermined space. The correction section corrects the output of the motion sensor using an output of the position sensor.
