Week 4
This Week we learnt about INTERACTION DESIGN
So what is INTERACTION DESIGN thing, The INTERACTION DESIGN is the design of interactive products and services in which a designer’s focus goes beyond the item in development to include the way users will interact with it.
What is involved in Interaction Design?
Understanding the problem space. Importance of involving users. Degrees of user involvement. What is a user-centered approach? Four basic activities of interaction design. A simple lifecycle model for interaction design.
This is the process of involved in Interaction Design
- Focused on discovering requirements
- designing to fulfil requirements
- producing prototypes and evaluating them
- Focused on users and their goals
- Involves trade-offs to balance conflicting requirements
Four approaches :
- user-centered design
- activity-centered
- design systems design
- genius design
Understanding the problem space
Explore
- What is the current user experience?
- Why is a change needed?
- How will this change improve the situation?
Articulating the problem space
- Team effort
- Explore different perspectives
- Avoid incorrect assumptions and unsupported claims
Importance of involving users
Expectation management
- Realistic expectations
- No surprises
- Timely training
- Communication
Ownership
- Make the users active stakeholders
- More likely to forgive or accept problems
- Can make a big difference in acceptance and success of product
Degrees of user involvement
consists of 4 things
- Member of the design team
- Face-to-face group or individual activities
- Online contributions from thousands of users
- User involvement after product release
What is a user-centered design?
User-Centered Design is an iterative design process in which designers focus on the users and their needs in each phase of the design process. In UCD, design teams involve users throughout the design process via a variety of research and design techniques, to create highly usable and accessible products for them.
Four basic activities of Interaction Design
- Discovering requirements
- Designing alternatives
- Prototyping alternative designs
- Evaluating product and its user experience throughout

Key Points
Four basic activities in interaction design process
- Discovering requirements
- Designing alternatives
- Prototyping
- Evaluating
User-centered design rests on three principles
- Early focus on users and tasks
- Empirical measurement using quantifiable and measurable usability criteria
- Iterative design
