Claim Text:
1. A hold state judging apparatus comprising: an acquiring section that acquires output signals of an angular velocity sensor and an acceleration sensor mounted in a mobile device held by a user; a pattern storage section that stores, in association with each other, information indicating a plurality of hold states of the mobile device and reference characteristic amounts of the output signals of the angular velocity sensor and the acceleration sensor obtained in advance respectively for the plurality of hold states; a hold state judging section that judges the hold state of the mobile device based on which of the reference characteristic amounts stored in the pattern storage section characteristic amounts of the output signals of the angular velocity sensor and the acceleration sensor acquired by the acquiring section correspond to; a plurality of positional change detecting sections that are provided to correspond respectively to the plurality of hold states of the mobile device and each detect positional change of the user; and a selecting section that selects, as the positional change of the user, the positional change output by the positional change detecting section corresponding to the hold state judged by the hold state judging section from among the hold states of the mobile device, wherein at least one positional change detecting section among the plurality of positional change detecting sections outputs the positional change of the user corresponding to a step length of the user and fluctuation of the output signals of the angular velocity sensor and the acceleration sensor.
