Output displays the processed results from a system. If forms are for data input, tables and charts are for data output, helping users understand, analyze, and make decisions. Tables are best for structured data in rows and columns, used when precise values, multiple attributes, specific data searches, or actions on data rows (edit, delete) are needed. Charts are ideal for visualizing patterns, trends, comparisons, or proportions quickly, rather than reading individual numbers. Examples of charts include bar charts, line charts, pie charts, and area charts.
The eleventh meeting of the Analysis and Software Design course focuses on user interface (UI) design. The speaker, Muhammad Diki Widianto, introduces himself and outlines the learning objectives: to design user interfaces for input and output, use UI design tools, and implement the designs in software.
A user interface is anything a user sees, touches, and uses to interact with a system, whether it's a desktop, mobile, or web application. A good UI is not only visually appealing but also functional, easy to understand, and efficient. Components of a UI include navigation, input forms, data output (tables, graphs), feedback mechanisms (notifications, alerts), and action elements (buttons, links).
Input forms are crucial for capturing data from users. Their main purposes are to collect data, ensure data validation and accuracy (e.g., email format, password complexity), facilitate transactions, personalize services, enable two-way communication, and provide authentication and security. Various form elements include text input, text area, password fields, dropdowns, radio buttons, checkboxes, toggles, date pickers, file uploads, sliders, and buttons.
Effective form design goes beyond aesthetics, considering psychological, cognitive, and technical aspects. Key principles include clear labels and instructions, structured grouping of fields, robust validation and error handling, distinguishing between mandatory and optional fields, appropriate size and touch targets, visual consistency, accessibility, and responsiveness across different devices. Providing clear feedback on user actions and system status (e.g., success/failure messages) is also vital.
When choosing a chart type, consider the communication goal (comparison, trend, composition). Avoid using pie charts for more than five or six categories; bar charts are a better alternative. Line or area charts are more suitable for time-series data. Maintain consistent and meaningful color usage, and always include clear labels, units, and legends. Accessibility, including color blindness considerations, should also be factored in by adding patterns, textures, or direct labels.
Before coding, designers use UI design tools to create visual mockups, wireframes, and interactive prototypes. Popular tools include Figma, Adobe XD, and Canva. These tools save time and cost during development. A demonstration of Figma shows how it's used to design a mobile academic information system, illustrating components like login screens and main dashboards, and highlighting features that help developers with spacing, sizing, and icon placement.
The speaker encourages students to explore Figma independently and provides an assignment: create a minimum 5-minute video summary of the lecture and upload it, submitting the link to Google Classroom within one week.
