What should a good interface design incorporate

1. I believe the answer is C. underlying structure of the applicationunderlying structure of the application would determine the type of pattern that would act like some sort of skeleton for the organized parts of the composition. Mistakes in this would be fatal for the overall design
2. That statement is true.In the end, the purpose of most application design is to enhance the experience of the users. So designer have to be able to distinguish which would be good to be used 'professionally' and which would be good to be used by common users.
3.WYSIWYG interfaces shield users from: A. CodeWYSIWYG stands for What you see is what You get. This allows the designer to see the end result while the interface is being created. This give the ability to change the layout of a document without needing to remember names of The commands
4. I believe the answer is c. Form follows functionForm follows function means that during the creation process, the shape should always be intended to serve the actual function/purpose rather than for purely aesthetical, which is very important in designing underlying structure.
5.I believe the answer is A. level of support the interface needs to provideIf the technology is intended for professional users, than the designer could afford to make minimum support for the interface. But if the technology is intended for entry level, more support for the interface would be needed.
6. That statement is true.Poor interface design will make the users confuse in how to use the actual application for its purpose. This could led them to believe the actual core of the application is in bad quality or even believe that the application is corrupted.
7.They shoul start it at: b. at the start of the design processAudience analysis will give you information on what type of audience are using it (including age and intent.) Based on this, you should design it for the purpose on serving that specific audience.
8. The one that considered an interface is: A. . the buttons on the screen of an ATMInterface is the medium that help the users use a certain technology. The interface does not include the core of what make the actual technology itself.
9. I believe the answer is C.Both the size of the database and the amount of menu options shall be determined by the IT department and the creator of the application. Even though the appealing visual is important, but the user experience is much more important for the designer.
10. The menu system would illustrate: A. interfaceThe menu system is used by the DVD users to interact with the technology and give appropriate commands for it. This serve the very definition of interface.
