The invention discloses a man-
machine interactive
system which provides an operating platform for man-
machine interactive equipment to extend and even execute a human thinking expression on a
machine. The man-machine interactive
system comprises an input unit, a storage unit, a
processing unit and an output unit, wherein the input unit is used for a user to carry out initial input of original information and confirming input of
relevant information; the storage unit is used for storing a
database which establishes a mapping relationship between first information characterizing
user input information and second information characterizing a mapping function item; the
processing unit is used for adopting the original information as a key word of the first information, retrieving the second information relevant to the first information in the
database and adopting the second information as the
relevant information of the original information; and the output unit is used for outputting the
relevant information so as to be convenient to execute the conforming input with the user in an interactive manner. In order to execute the extended expression, a corresponding executing unit or a corresponding executing module is further needed. In addition, the invention also discloses a relevant
system, a device and a method. The invention realizes the man-machine interactive mode (namely, what you think is what you get) and changes man-machine interactive habits.
