PROBLEM TO BE SOLVED: To more accurately estimate a travel direction according to a user action state.SOLUTION: An information processing device comprises an acceleration acquisition unit 51, an action estimation unit 53, and a travel direction estimation unit 55. The acceleration acquisition unit 51 acquires an acceleration generated by a user action. The action estimation unit 53 estimates whether the user action is walking or running on the basis of the acceleration acquired by the acceleration acquisition unit 51. The action estimation unit 53 selects one from a plurality of travel direction estimation methods for estimating a user travel direction on the basis of the estimation results of the user action. The travel direction estimation unit 55 estimates the user travel direction according to the travel direction estimation method selected by the action estimation unit 53.SELECTED DRAWING: Figure 2

    【課題】ユーザの行動状況に応じて、より正確に進行方向を推定する。【解決手段】情報処理装置は、加速度取得部51と、行動推定部53と、進行方向推定部55を備える。加速度取得部51は、ユーザの行動によって発生する加速度を取得する。行動推定部53は、加速度取得部51によって取得された加速度に基づいて、ユーザの行動が歩行であるか走行であるかを推定する。また、行動推定部53は、ユーザの行動の推定結果に基づいて、ユーザの進行方向を推定するための複数の進行方向推定方法から1つを選択する。進行方向推定部55は、行動推定部53によって選択された進行方向推定方法によって、ユーザの進行方向を推定する。【選択図】図2
