Abstract
For the decline in birthrate, the labor shortage of young generation becomes social problem. In order to solve this problem, it is necessary to improve the social surrounding of working by the parent with the infant feeling easy. In this study, the system for shortening the distance of the parent and the infant who was left to the house of parent or the nursery is developed. This system gives comfort and peace of mind to the infant by transmitting the heartbeat of the parent which the child is hearing through Internet and reproducing it in the doll which the child has held. At the same time, this system also gives peace of mind to the parent by observing the condition of the infant by the network camera anytime. Then, it is confirmed that the steady artificial heartbeat could be accurately transmitted and confirmed that the unsteady heartbeat could be almost accurately transmitted using the crosscorrelation function and the power spectrum.
