Abstract: A computing system includes a viewing screen, user interface means, a plurality of application processes, a data file and agent engine means. The viewing screen displays images. The user interface means enables a user to select and move the images displayed by the viewing screen. Each application process in the plurality of application processes includes command processor means and action processor means. The command processor means receives semantic commands and executes the semantic commands. The action processor means monitors selection and movement of the images on the viewing screen and generates the semantic commands by lexical and syntactical analysis of the selection and movement of the images on the viewing screen. The semantic commands are sent to the command processor for execution. The data file includes first semantic commands executable by a first application process from the plurality of application processes.
