Research on artificial intelligence and sensitivity control technology progmses in recent years, and the technology of imitating human thinking, feeling, and sensitivity have been established. However, research on Sentience as the way of idea generation and intuition that are the origin of human being's intellectual production activity seems to have just started. Moreover, although thg field of quantum computer is also being researched briskly, no practical results have been produced yet. In this paper, a new machine called Sentience System Computer (SSC) is presented. SSC is an intuition computer system having self-intention. According to the interpretation in the many-worlds quantum theory, the spontaneous intuition of human can be defined as what is produced by interference from the self multiple worlds which are resulted from all piles of self-history. In this paper, we present the principles and practices of SSC, the basic spontaneity type algorithm. When applying SSC to sensitivity control technique, the process of generating sentience, the procedure of human conceives, the state of Idea Database and some recent results of SSC, are given also.
