1. An estimating apparatus comprising:
- a detector that detects accelerations;
an identifying unit that identifies a gravity direction using an average of the accelerations that the detector detects in a certain state; and
an estimating unit that estimates a travel direction based on the gravity direction that the identifying unit identifies from the accelerations that the detector detects.
