The menu structure for Holiday Travel Vehicle’s existing character-based system is shown here. Develop and prototype a new interface design for the system’s functions, using a graphical user interface. Assume that the new system will need to include the same functions as those shown in the menus provided. Include any messages that will be produced as a user interacts with your interface (error, confirmation, status, etc.). Also, prepare a written summary that describes how your interface implements the principles of good interface design as presented in the textbook.
