Study Notes
- Human-Computer Interaction is the subject of this lecture.
Interaction Methods
- Interaction methods include multitouch, speech, GUI, text-based UI, head-up displays, augmented reality, and gesture-based interfaces.
Interaction Types
- Interaction can be categorized into instructing, conversing, manipulating, and exploring:
- Instructing involves users issuing commands to a system through typing, menu selection, speaking, gesturing, or pressing buttons.
- Conversing involves a dialogue with a system where users input questions via text or speech, and the system responds accordingly.
- Manipulating is direct interaction with objects in a virtual or physical space, such as opening, holding, closing, or placing items.
- Exploring involves users navigating through virtual or physical environments like 3D worlds, augmented reality, or smart homes.
Practical Exercise: Interactive GPS/TV System
- Design an interactive GPS/TV system for new vehicle lines in a group of four within 10 minutes.
- Define the environment setup (sensors, devices), sketch the screen layout, and describe how users will interact with the system.
Identifying the Problem Space
- When designing, consider problems with existing products or user experiences.
- Investigate potential problems, reasons behind them, and how design ideas address them.
- For new user experiences, evaluate how design ideas support, change, or extend current practices.
Understanding the Problem Space
- Assumption: Taking something for granted that needs further investigation.
- Claim: Stating something as true when it is still open to question.
Use Cases: 3D TV vs Curved TV
- 3D TV:
- Assumptions: People accept wearing glasses and paying more.
- Claims: Enhanced clarity and color detail are appreciated through 3D.
- Unknowns: The actual desirability of the living room experience.
- Curved TV:
- Assumptions: Offers more flexibility for viewers to optimize viewing angles.
- Claims: Appeals to big families with its new display experience.
- Unknowns: The actual desirability of the living room experience.
Interaction Design Approaches
- User-Centered:
- The user is the guide.
- Designer translates user needs and goals into the system solution.
- Activity-Centered:
- User behavior is captured.
- The user is important, but the behavior, not there needs and goals is important.
- System:
- The user defines the goals of the system.
- Structured, rigorous, and holistic
- Genius:
- Based on creativity and experience.
- The user only validates ideas generated by the designer.
User Intervention
- Methods involve users in design through prototypes.
- Involves managing user expectation such that disappointment = expectation / reality.
User-Centered Design Principles
- Early and continuous focus on users and tasks.
- Consider Tasks & Goals: What and how a user does his/her job.
- Consider Behavior and Context of use: Priorities, preferences, and implicit intentions.
- Consider User Characteristics: Size of hands, length, age, etc.
- Define usability and user experience goals empirically.
- Goals include effectiveness, efficiency, safety, utility, learnability, and memorability.
- Iterate the design through testing, measuring, and redesign.
Exercise: User-Centered Online Flower Shop
- Design an online shop for selling flowers using a user-centered approach.
Identifying Users for Design
- Identifying users is not straightforward; they can be primary, secondary, or tertiary:
- Primary Users: Frequent, hands-on users of the system.
- Secondary Users: Occasional users or those who use the system through an intermediary.
- Tertiary Users: Those affected by the system's introduction or who influence its purchase.
User Needs
- It's important to remember that stakeholders don't necessarily always need the product.
- It is important to study characteristics and capabilities of the user.
- Determine what they are trying to achieve.
- Evaluate how they achieve it correctly?
- Assess how to achieve more effectively and enjoyable experiences
'Un-dreamed-of' Need
- People don't necessarily know what is possible.
Exercise: Traveller Planner Web-Site
- What are user needs?
- Make a list of the top user experience and usability goals for the system.
- Outline the initial screen or two for this system
