Strategies and guidelines for designing effective user interfaces include organizing related elements together, keeping tasks simple, ensuring all needed options are visible without distractions, providing clear feedback, and allowing for flexibility and reuse. Tools for designing user interfaces enable independence from code, rapid prototyping, and consistency. They include Tcl/Tk for menus, Java for animations, JavaScript for form validation, and programs for evaluation and critiquing. User interface design involves following principles of structure, simplicity, visibility, feedback, and tolerance while using tools to create prototypes and enforce standards.

- 2. Q No. 1. How to design an effective User Interface? Explain in terms of tools, technologies , guidelines and strategies. Ans. Strategies for designing effective user interface 1.The structure principle Design should organize the user interface purposefully, putting related things together and separating unrelated things. 2.The simplicity principle Design should make simple, common tasks simple to do, communicating clearly and simply in the user’s own language. 3.The visibility principle Design should keep all needed options and materials for a given task visible without distracting the user with extraneous or redundant information. 4.The feedback principle Design should keep users informed of action, changes and errors that are relevant to the user through clear, concise, and unambiguous language familiar to users. 5.The tolerance principle Design should be flexible and tolerant, reducing the cost of mistakes and misuse by allowing undoing and redoing and by interpreting all reasonable actions reasonable. 6.The reuse principle Design should reuse internal and external components and behaviors, maintaining consistency. Guidelines for Designing an Effective User interface 1. Create hierarchies of objects and actions that are complex 2. Set standards and stick to them to verify consistency 3. Set reasonable navigation between major user interface items 4. Place navigations within the page 5. Word your messages and labels effectively 6. Use color combinations appropriately 7. Follow the contrast rule effectively 8. Align fields effectively 9. Avoid busy user interfaces

Popular terms include 1. Rapid Prototyper 2. User Interface Builder 3. User Interface Management System 4. User Interface Development Environment 5. Rapid Application Developer 1. Features of Interface-Building Tools User Interface Independence Separate interface design from internals Enable multiple user interface strategies Enable multiple platform support Establish user interface architect role Enforce standards 2. Methodology & Notation Develop design procedures Find ways to talk about design Create project management 3. Rapid Prototyping Try out ideas very early Test, revise, test, revise,...and continue Engage end users, managers, and others 4. Software Support Increase productivity Offer some constraint & consistency checks Facilitate team approaches Ease maintenance 2). Software Engineering Tools Tcl / Tk : used to make hierarchy of menus and sub menus Java : used to make animations Javascript : class library of Java used for form validation 3). Evaluationand Critiquing Tool Tullis' Display Analysis Program, Version 4.0 Doctor HTML - Web Page Analyzer 4). Menus, icons and Form fillings To take data in forms, and makes easy selections
