PROBLEM TO BE SOLVED : To provide an information processor, an information processing system and an information processing method for achieving practical speed or movement distance detecting accuracy by preventing the deterioration of the speed or movement distance detecting accuracy due to the accumulation of errors by arithmetic processing.SOLUTION : Since there exists a fact that the occurrence of an arithmetic error is rare in the first half period during the operation of an operation device 10 by a user, and that the occurrence of the arithmetic error is frequent in the latter half period during the operation, and there exists similarity between the characteristics of acceleration and deceleration in an unconscious operation, the information of the arithmetic result of the movement of the operation device 10 within a period from an acceleration end time to a movement end time is corrected on the basis of information acquired within an acceleration period when the occurrence of the arithmetic error is rare. Thus, it is possible to prevent the deterioration of movement detecting accuracy due to the accumulation of errors by arithmetic processing, and to achieve practical movement detecting accuracy.COPYRIGHT : (C)2012, JPO&INPIT
