There is provided an information processing apparatus that includes a plurality of pieces of sensing data in different forms obtained from a plurality of sensors each sensing a state related to a performance by a motion of a user, an information processing section that processes the sensing data converted by the conversion section, and an information output section that outputs feedback information to the user on the basis of a processing result of the information processing section. The conversion section converts the sensing data in an analog form from the sensors into sensing data in a digital form and outputs the sensing data in the digital form to the information processing section, and converts the sensing data in the digital form from the sensors into sensing data in the analog form and outputs the sensing data in the analog form to the analog-digital signal conversion section.
