Study Notes
HCI Guidelines Overview
- HCI principles are broad and apply to various aspects of human-computer interaction design.
- Guidelines offer specific advice on design implementation yet can be challenging to integrate due to multiple factors and potential conflicts.
- Guidelines can be categorized into criteria and categories, and while detailed, they lack explicit incorporation instructions in design.
Important Contributors
- Jennifer Tidwell is a notable figure in interaction design, known for compiling user interface design patterns into guidelines.
- She has worked with companies like Google and MathWorks, focusing on interaction design and pre-design analysis.
Criteria and Categories of Guidelines
- General HCI Design: Focuses on display layout, information structure, user experience, and aesthetics.
- User Type: Considers demographic factors like age, disability, occupation, and culture to tailor design.
- Platform/System: Differentiates designs for mobile, desktop, and embedded systems.
- Vendor/Organization: Reflects design styles and identities, e.g., NASA, iOS, Android.
- Interface Style/Modality: Involves traditional interfaces (WIMP) and emerging multimodal interfaces.
- Task/Operational Context: Accounts for environmental factors affecting user interaction.
- Applications: Covers various domains like gaming, e-commerce, and design/editing tools.
Visual Display Layout
- Emphasizes the organization of information on screens or scrollable pages.
- U.S. Department of Health and Human Services guidelines for web layout include:
- Avoidance of clutter and optimization of display density.
- Consistent alignment and strategic placement of important items.
- Structuring content for easy comparison and establishing visual hierarchy.
Taking User Input
- Focus on enhancing user input mechanisms to improve efficiency and accuracy in high-interaction systems.
- Graphical User Interface (GUI) elements include buttons, text boxes, and icons designed for user engagement.
- Guidelines to facilitate data entry include:
- Consistency in actions and clear labeling for fields and buttons.
- Minimization of user inputs and memory load.
- Logical arrangement of entry fields for intuitive scanning.
User Accessibility Guidelines (WCAG 2.1)
- Created by the World Wide Web Consortium (W3C) to enhance web content accessibility for individuals with disabilities.
- Key principles of WCAG:
- Perceivable: Information must be accessible in various formats.
- Operable: All functionality should be keyboard accessible; navigation aids are essential.
- Understandable: Content should be easy to read with predictable interactions.
- Robust: Content should be compatible with assistive technologies and evolving user agents.
Mobile Device Usability
- Emphasizes the significance of user experience on smartphones and mobile applications due to their widespread use.
- Summary of HCI guidelines for mobile devices includes:
- Provision of fast status information related to connectivity.
- Reduction of typing through diverse input methods (touch, voice).
- Intense task focus to minimize confusion in dense information.
- Design of large hit targets for ease of use.
- Efficient utilization of screen space to enhance user interaction.
