76. 2 Chapter 2: Program and Graphical User Interface Design76 Phase 2: Design the User Interface ►Principles of User Interface Design The GUI should be easy to use and follow ►Users will not be satisfied with the application if the user interface is not easy to use Three primary means of interacting in a user interface are the keyboard, a pointing device, and voice input Use of the interface should feel natural and normal Provide the most appropriate object for each requirement

77. 2 Chapter 2: Program and Graphical User Interface Design77 Phase 2: Design the User Interface Once an object is used for a particular purpose, then that object should be used for the same purpose throughout the program interface Arrange objects in the sequence in which they are used The interface should be kept as simple as possible, while maintaining functionality The user interface should be intuitive
