    1. State some features which affect popularity of web user interface. (June 2011Graphics revolutionized design and the user interface. Graphics assumes three dimensional look whereastext based system assumes one dimensional look. Information can appear or disappear through floatingwindows and navigation and commands can be done through menu or pull downs or screen controlsIncreased computer power and the vast improvement in the display enable the users actions to be reactedto quickly dynamically and meaningfully.

    2. !efine "uman #omputer Interaction . (June 2012!ser interface design is a subset of a field of study called human"computer interaction #$%I&. $uman"computer interaction is the study planning and design of how people and computers work together so thata persons needs are satisfied in the most effective way.

    'nother researcher has reported that reformatting inquiry screens following good design principles reduceddecision"making time by about () percent resulting in a savings of *+ person"years in the affected system.,ther benefits also accrue from good design #-arat 1++*&. raining costs are lowered because trainingtime is reduced support line costs are lowered because fewer assist calls are necessary and employeesatisfaction is increased because aggravation and frustration are reduced.

    ypical examples include those for letting customers check on an orders status or letting suppliers viewrequests for proposals. 'n extranet is a blend of the public Internet and the intranet and its design shouldreflect this.
