An information processing apparatus includes: a memory; and a processor coupled to the memory and configured to: detect a change in a traveling direction of a walker with the information processing apparatus; detect, while a change amount of the traveling direction is less than a first threshold value, a first amount of travel of the walker for each step based on an amplitude component of the information processing apparatus in an up and down direction; estimate a position of the walker using the first amount of travel; and estimate, when the change amount of the traveling direction is equal to or more than the first threshold value, the position of the walker using the detected first amount of travel while the change amount is less than the first threshold value.
