- However, there are also potential dangers concerning the risks of extremes, terrorism, oppressive social policies, racial hatred.
- In addition, powerful social media needs a balance between legal protections, police powers, and privacy.
Usability Motivation by Domain
- Consumer Electronics & Social Media: UI designs are vital marketing tools for consumer electronics sales, impacting personal communication, education, healthcare, and entertainment. Relevant products are often featured in advertisements and media coverage.
- Games & Entertainment: Computer games have expanded, impacting education, rehabilitation, and home entertainment. UI design has become a significant factor in attracting players and driving market growth.
- Professional Environments: PoS (Point of Sale) teller applications, nuclear reactor control panels, and other critical systems require robust USI to ensure reliability and effectiveness, even under stress.
- Exploratory, Creative & Collaborative Platforms: Web browsers, search engines, data visualization tools, and collaboration platforms rely on UI design to foster discovery, creativity, and knowledge sharing, while also prioritizing user-friendliness.
- Socio-Technical Systems: Usability in systems with prolonged user interaction is crucial. Systems like healthcare, community service, and disaster response systems rely on user-friendly interfaces that encourage user trust and ensure proper functionality.
Usability Goals
- These design principles include safety, effectiveness, efficiency, learnability, retrievability, and user satisfaction, which encompass safety, effectiveness (e.g., conducting tasks), efficiency (e.g. time considerations), learnability (e.g., ease of learning, remembering), high speed of user task output, low error rate, satisfaction.
Interaction Design (ID)
- ID is a concept comprising a set of aspects aimed at researching and designing computer-based systems that serve human needs.
- It focuses on supporting how people communicate and interact in everyday and professional contexts.
HCI & Interaction Design
- HCI and ID are linked and involve various interconnected disciplines.
Improving Interfaces
- Improving interfaces involves changing software professionals' attitudes to adopt and enhance UI design methods and techniques within their development methodologies.
- Ease of use is vital for computer products as ease of access impacts user success rates.
- Knowing the user, including their physical, cognitive, personality, skill sets, cultural influences, motivation, and special needs is essential for enhancing interface design.
- For a good user interface, the UI structure must match the capabilities of the system and should help the user develop an intuitive mental model of how the system functions.
- A good user interface is adaptive, helping users absorb information based on usability goals, first-time use, infrequent use, or expert use.
Human Computer Interaction Design (HCID) Scope
- The main goal of HCID is crafting systems that are user-friendly.
- Understanding the users, including their motivations, levels of experience, and the tasks they intend to perform, is paramount in HCID.
- It's essential to consider the working environment and its feasibility constraints within HCID.
HCID Principles
- Understanding users and applications, ensuring self-evident feature operation, leveraging users' familiarity across systems, and prioritizing user-friendliness are key principles in HCID.
- Avoiding hindering user progress with design choices, like creating simple ways for users to address errors, is essential.
The User's Experience
- A user's experience goes beyond the operational aspects of an object and considers feelings and satisfaction.
- People's experiences depend on how a product behaves and is used in real-world contexts, including satisfaction or pleasure with a product.
Two Crucial Errors in Design
- Avoiding errors like assuming all users are identical or that all users function like designers is critical in interaction design.
Core Characteristics of Interaction Design
- User involvement in design, defining specific usability goals, and emphasizing iteration through design are crucial aspects of effective interaction design.
User-Centered Design (UCD)
- UCD is a framework and focus on user needs, engaging users throughout the design process, integrating design, and incorporating continuous user testing and iteration.
- Its objective aligns designed features with user abilities and expectations.
- Complexity levels are more pronounced when considering many users rather than a limited few.
- User differences highlight the need for designing a universal user experience.
Typical UCD Cycle
- The UCD cycle comprises stages such as defining the application, gathering user requirements, conducting task analysis, gathering information about users and tasks, exploring new ideas/questions, creating the first design, evaluating the design, developing the app, following up the development, and eventually, releasing the app.
UCD Phases
- Key phases include defining the application, identifying user requirements, analyzing tasks, gathering user information, exploring ideas, designing prototypes, testing designs, and implementing developments, following up on usability assessments, and eventually releasing the product. Evaluating the product post-release is also a key consideration.
Skills in HCI
- Designers utilize visual and audio design and design processes, programmers employ systems, toolkits, and languages with strong software engineering techniques, and researchers apply cognitive principles, theories, and experimental techniques to the field.
Professionals in Interaction Design (ID)
- Different specialists are needed for effective interaction design, including interaction designers, usability engineers, web designers, information architects, and UX designers.
Working in Multidisciplinary Teams
- Multidisciplinary teams bring different perspectives and diverse expertise while working on a project.
- However, communication challenges and navigating conflicting ideas can arise.
Seven Deadly Mistakes in User Interface Design
