What are different considerations while designing user interface for an information system. ## Short answer A standard UI includes input forms, control buttons, output reports, search screens, and help. Design considerations: know the user, ensure consistency, simplicity, clear feedback, error prevention, easy navigation, accessibility, adequate performance, help, security, and device compatibility. ## Answer #### Standard user interface in terms of parts of an information system A **user interface (UI)** is the point where the user interacts with the system. In an information system, it has a standard form for each part: - **Input (data entry):** forms, menus, dialog boxes, drop-down lists, checkboxes, barcode or touch entry; with validation, default values and error messages. - **Processing / control:** command buttons, menus and function keys to start, save, search and cancel; progress indicators and confirmation of actions. - **Output:** reports, screens, charts, dashboards, print previews and alerts, in a clear and consistent format. - **Database / storage access:** search screens, query forms and record browsing with filters. - **Help and navigation:** help text, tooltips, breadcrumbs, links and menus. - **Types of interface:** command line, menu driven, graphical (GUI), form based, natural language/voice, web and mobile interfaces. #### Considerations when designing a user interface 1. **Know the user:** skill level, role, language and disabilities. 2. **Consistency:** the same layout, colours, terms and shortcuts on all screens. 3. **Simplicity:** uncluttered screens showing only needed information. 4. **Feedback:** the system should respond to each action, with clear and helpful error messages. 5. **Error prevention and recovery:** validation, confirmations and undo. 6. **Ease of navigation:** logical flow and few steps to complete a task. 7. **Accessibility and readability:** font size, contrast, colour use, and support for local language (Nepali). 8. **Response time and performance.** 9. **Help and documentation.** 10. **Security:** login, roles and hiding sensitive data. 11. **Device compatibility:** works on desktop, tablet and mobile. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. Which interface features belong to the input part of an information system? A. Forms, drop-down lists and checkboxes with validation and defaults B. Print previews and charts C. Breadcrumbs and tooltips only D. Backup schedules Answer: A. Data entry uses forms, menus and lists with validation, default values and error messages. (Key point: Input part) 2. What does the consistency consideration require? A. Different layouts per screen B. The same layout, colours, terms and shortcuts on all screens C. Random colours D. Frequent term changes Answer: B. Consistency means uniform layout, colours, terminology and shortcuts. (Key point: Consistency) 3. What does the feedback principle require? A. The system responds to each action with clear, helpful error messages B. Silent failures C. Messages only in code D. No confirmation of actions Answer: A. The system should respond to each action with clear messages. (Key point: Feedback) 4. Which accessibility consideration is mentioned for Nepal? A. Support for local language (Nepali), font size and contrast B. Only English text C. Tiny fonts D. Colour-only signals Answer: A. Accessibility includes font size, contrast, colour use and Nepali language support. (Key point: Local needs) ## Related in Information System - [Strategic information system and benefits](https://www.bctengineer.com/question.md?key=semester_8%2Finformation_system%3Astrategic-is-benefits) — Information System, chapter 1, asked 2× - [Geographic Information System](https://www.bctengineer.com/question.md?key=semester_8%2Finformation_system%3Agis-characteristics-uses) — Information System, chapter 1 - [Short note: HR information system](https://www.bctengineer.com/question.md?key=semester_8%2Finformation_system%3Ashort-note-hris) — Information System, chapter 6 - [Recommender system design and types](https://www.bctengineer.com/question.md?key=semester_8%2Finformation_system%3Arecommender-design-types) — Information System, chapter 7 - [Information audit and its benefits](https://www.bctengineer.com/question.md?key=semester_8%2Finformation_system%3Ainformation-audit-benefits) — Information System, chapter 2 - [MIS vs DSS information and processing](https://www.bctengineer.com/question.md?key=semester_8%2Finformation_system%3Amis-vs-dss-information-processing) — Information System, chapter 4 ## Related in other subjects - [Multimedia user interface design process](https://www.bctengineer.com/question.md?key=semester_8%2Fmultimedia_system%3Aui-design-process) — Multimedia System, chapter 6, asked 2× - [Input/output interface unit design factors](https://www.bctengineer.com/question.md?key=semester_5%2Finstrumentation_ii%3Aio-interface-unit-importance) — Instrumentation II, chapter 7 - [System administration; special vs general user](https://www.bctengineer.com/question.md?key=semester_6%2Foperating_system%3Asysadmin-special-vs-general-user) — Operating System, chapter 9 - [Special considerations in hill road design](https://www.bctengineer.com/question.md?key=semester_6%2Ftransportation_engineering_i%3Ahill-special-considerations) — Transportation Engineering I, chapter 5, asked 5×
