1. A method for determining moods of a horse, comprising the steps of: determining, by a plurality of sensors, physiological parameters of the horse, including determining at least one of a movement and position of at least one ear of the horse, wherein one of the sensors used for determining the at least one of a movement and position of the at least one ear is a motion sensor determining intensity of movement and/or orientation in space of the at least one ear, the motion sensor being one of a magnetic field sensor and an acceleration sensor, and determining at least one of a movement and position of the head of the horse and calculating the at least one of a movement and position of the at least one ear relative to the head; recognizing and quantifying body language signals mediated by the at least one of a movement and position of the at least one ear relative to the head determined in said step of determining; and outputting a statement derived from the determined physiological parameters indicating the moods of the horse.
