Study Notes
HCI Guidelines Overview
- HCI principles are broad and applicable across various aspects of interaction design; guidelines are specific recommendations for implementation.
- Challenges in applying guidelines arise from complex design considerations, particularly in enterprise systems, and potential conflicts between guidelines necessitating prioritization by designers.
Categories and Criteria of HCI Guidelines
- Guidelines can be categorized into types and criteria, such as:
- General HCI Design: Includes display layout, input solicitation, output visualization, and overall user experience.
- User Type: Considers demographics such as age, disability, occupation, and culture.
- Platform/System Setup: Involves different devices like mobile, desktop, cloud-based systems.
- Vendor/Organization Identity: Recognizes design styles associated with specific brands or organizations.
- Interface Style/Modality: Covers types of interfaces, including WIMP and non-WIMP interactions.
- Task/Operational Context: Refers to environment factors like location and time that affect user interaction.
- Applications: Examples include gaming, media services, and social networking interfaces.
Display Layout Guidelines
- Effective display layout organizes content and interface elements for optimal visibility.
- U.S. government guidelines recommend:
- Avoidance of clutter and optimization of display density.
- Consistent alignment and positioning of important items, particularly at the top center.
- Structuring content for easy comparisons and appropriate length considerations.
Data Entry Guidelines
- Guidelines for facilitating efficient user input in interactive systems include:
- Ensuring consistency in data-entry actions and minimizing required input by users.
- Designing clear forms and dialog boxes with logically placed and clearly labeled buttons.
- Matching entry sequences with natural hand movements to reduce cognitive load.
Accessibility Standards
- WCAG 2.1 introduced by W3C focuses on web content accessibility for users with disabilities, highlighting:
- Perceivable: Must provide alternatives for non-text content and ensure information can be easily seen and heard.
- Operable: Functionality must be navigable via keyboard, with enough time given to users for content consumption.
- Understandable: Text must be readable and web pages predictable in operation.
- Robust: Content should be compatible with various user agents, including assistive technologies.
Mobile Device Guidelines
- Increased focus on usability for smartphones and mobile applications, summarized guidelines include:
- Providing fast status updates for connectivity and services.
- Reducing user input through multiple control methods (touch, voice, etc.).
- Enhancing task focus to minimize confusion in information-heavy environments.
- Designing large hit targets for easy selection and interaction, while effectively utilizing screen space.
