1. An information processing system comprising a sense of augmented reality presentation apparatus that is able to synthesize and display an image of real space and computer graphics image data, and a failure analysis apparatus that is able to analyze a fault having occurred in a computer system, wherein the failure analysis apparatus comprises: obtaining means that obtains information associated with an operational status of the computer system; determination means that determines information regarding fault repair work for the computer system, based on the information associated with the operational status obtained by the obtaining means; and transmission means that transmits the information regarding the fault repair work determined by the determination means, to the sense of augmented reality presentation apparatus, the sense of augmented reality presentation apparatus comprises: presentation means that synthesizes and presents computer graphics image data for providing guidance for a method of the fault repair work, with the image of the real space, based on the information regarding the fault repair work, and in the failure analysis apparatus: after the fault repair work according to the guidance presented by the sense of augmented reality presentation apparatus, if the information associated with the operational status of the computer system is newly obtained by the obtaining means, the information regarding the fault repair work for the computer system is newly determined by the determination means based on the information associated with the operational status, and the newly determined information regarding the fault repair work is transmitted to the sense of augmented reality presentation apparatus by the transmission means.
