ELECTRONIC APPARATUS, SPATIAL DISPLACEMENT COMPUTING DEVICE, AND SPATIAL DISPLACEMENT COMPUTATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electronic apparatus which has sufficient sensitivity to a linear movement and can detect a movement of the apparatus more reliably.

SOLUTION: The electronic apparatus is provided with: a case body of a size which can be held and operated by hand; an angular velocity sensor which is placed in the case body and outputs a signal in accordance with an angular velocity in the rotation direction by detecting a spatial movement amount of the case body; an acceleration sensor which is placed in the case body and outputs a signal in accordance of an acceleration in the linear direction by detecting the spatial movement amount of the case body; a means for compensating the output of the angular velocity sensor by the output of the acceleration sensor; and a means for calculating spatial displacement of the case body according to the output of the angular velocity sensor compensated by the output of the acceleration sensor.
