The present invention accurately estimates the travel direction of a user on the basis of a sensor signal from a mobile device held by the user even if the user moves the mobile device to the left and right while traveling. Provided are a travel direction information output device, travel direction information output method, and program. The travel direction information output device is provided with a travel direction estimation unit for estimating the travel direction of a user, a rotation amount calculation unit for calculating the amount by which a mobile device held by the user rotates around a gravity axis, and a selection unit that is connected to the travel direction estimation unit and rotation amount calculation unit and selects, on the basis of the calculated rotation amount, whether to output travel direction information corresponding to a travel direction calculated by the travel direction estimation unit or to output travel direction information in which already output travel direction information is maintained. |
