An information processing device includes: a posture change determining unit that determines, based on an output value of an inertial sensor, whether a posture state of a moving object has changed; a reference orientation generating unit that, when it is determined that the posture state of the moving object has changed from a first posture state into a second posture state, generates a reference orientation corresponding to an orientation of the moving object at that time calculated from the output value of the inertial sensor; and an orientation error calculating unit that, when it is determined that the posture state of the moving object has changed from the second posture state into the first posture state, calculates an error of an orientation of the moving object according to the reference orientation, and an orientation at that time calculated from the output value of the inertial sensor.

A direction estimating device estimates a user direction indicating a direction of a body of a user. The direction estimating device includes: a storage unit that stores direction information indicating a direction determined in advance as the user direction of when the user operates an input device with a particular attitude; a detecting unit that detects that the user is in the particular attitude; and an estimating unit that estimates the user direction based on the direction information when the user has been detected to be in the particular attitude.

The present invention is concerning an information processing apparatus includes a record-information storage unit, a determining unit, a measuring unit, and an identifying unit. The record-information storage unit stores therein an already-identified person's motion together with time. The determining unit determines possible motions that a person can make from the already-identified person's motion. The measuring unit measures measurement information according to a person's motion. The identifying unit performs a pattern detecting process for detecting a pattern similar to the measurement information measured by the measuring unit in patterns corresponding to the possible motions determined by the determining unit out of predetermined patterns of measurement information for person's motions, and identifies a motion corresponding to the detected pattern as a motion that the person made.

An information processing apparatus includes a storage unit, an estimating unit, a judging unit, and a determining unit. The storage unit stores therein information of a walking state and a first location representing a location where the walking state occurs in an associated manner. The estimating unit estimates the walking state on the basis of measurement information measured in response to person's walking. When the walking state has been estimated, the judging unit judges whether or not the first location associated with the estimated walking state exists near a second location representing a location calculated by autonomous navigation based on the measurement information. When it has been judged that the first location exists near the second location, the determining unit determines the first location to be person's current location.
