Abstract: There is provided an information processing method to improve convenience for a user regarding correction of a drift error. The information processing method includes performing an estimation of posture information of a moving body including a first rotation angle around an axis in a gravity direction and a second rotation angle around an axis orthogonal to the gravity direction on the basis of an output from a gyro sensor attached to the moving body; and performing a correction of the first rotation angle in a case where a condition regarding the second rotation angle is satisfied.

Abstract: A tablet input device includes a manipulation pad with a group of parallel drive lines and a group of sense lines which are interlaced in parallel with the drive lines. A drive circuit is provided which sequentially scans the drive lines with a variable drive current. When an input pen indicates a point on the face of the manipulation pad and when one of the drive lines adjacent to this point is excited, a voltage is induced across one or more sense lines adjacent the excited drive line. A sense circuit is provided which detects the magnitude or the polarity of the induced voltage, thereby detecting the address of the point indicated by the input pen.
