1. An interaction device for interacting with an object, comprising:

  • a central processing unit;

    an input unit that receives input information;

    an output unit that outputs output information;

    a controller that maps the input information into the output information;

    an optimization unit that optimizes the controller,wherein the output unit outputs an imitation of a movement of the object,wherein the controller implements a Bayesian'"'"'s estimation that determines a degree of belief or conviction of an existence of an interaction object by comparing past records on the basis of a plurality of variables including a first variable indicating a total number of background periods until a predetermined time point, a second variable indicating a total number of agent periods until the predetermined time point, a third variable indicating a total number of sensors that receive an input within the total number of background periods indicated by the first variable, and a fourth variable indicated a total numbers of sensors that receive an input within the total number of agent periods indicated by the second variable, andwherein the controller uses a time counter to determine whether a current time is within an agent period or a background period, and the time counter is set to an initial value when a sensor of the interaction device receives an input and is increased when sensors of the interactive device receive no input for a predetermined time step, andwherein the optimization unit optimizes the controller to maximize an expectation of returned information about a hypothesis of an interaction object.
