Abstract: An information processing apparatus configured to determine a condition of an animal that is other than a human and moving on a mobile body. The information processing apparatus includes one or more processors and one or more memories communicatively coupled to the one or more processors. The one or more processors are configured to execute: obtaining a first vibration detection result indicating vibration of the animal and a second vibration detection result indicating vibration in a surrounding environment of the animal; and determining the condition of the animal based on the first vibration detection result, the second vibration detection result, and a vibration pattern that is accumulated in a database.
