Abstract: The present invention put forth a method for users to give commands directly in computer software through use of a command input module, a command dictionary or database with synonyms, a user command dictionary or database, a command search engine and a dynamical command execution module. The command search engine gets the command input from the command input module and searches the command dictionary or database and the user command dictionary or database, if a matching command with the command input is found, the dynamical command execution module is called to execute the command directly; if one or more synonymous or similar commands are found, a dynamical user interface with all the found commands is displayed for the user to select and execute; if no matching commands or synonymous commands are found, a message stating that the command input cannot be found in the software is displayed to the user.

Abstract: A human-machine interface with learning while using functionality, is involved with the fields of communication interface between human and machine. The present invention lets users obtain intelligent and pertinent operation guides and/or help according to the user's operation situations and/or the document state without resorting to the user manual or the help system, providing an intelligent human-machine interface with learning while using functionality, thus augments greatly the ease of use for computers and electronic appliances.
