Chapter 2: The process of interaction design

What are some practical issues of user centered design?

Practical issues of user centered design: • Who are the users? • What are the users' needs? • How to generate alternative designs • How to choose among alternatives • How to integrate interaction design activities with other lifecycle models

What principles can the early focus on users and tasks principles be divided into:

The early principles and tasks principles can be divided the following principles: -Users' tasks and goals are the driving force behind the development. -Users' behavior and context of use are studied, and the system is designed to support them -Users' characteristics are captured and designed for -Users are consulted throughout development from earliest phases to the latest. -All design decisions are taken within the context of the users, their activities, and their environment.

What are the four approaches to interaction design?

The four approaches to user-centered design, activity-centered design, systems design, and genius design

What are the four basic activities of Interaction Design?

The four basic activities of Interaction Design: 1.Discovering requirements: it is focused on discovering something new about the world and defining what will be developed. 2.Designing alternatives 3.Prototyping 4.Evaluating: It is the process of determining the usability and acceptability of the product or design measured in terms of a variety of usability and user-experience criteria.

What are the four phases in interaction design?

The four pahases in interaction design are: • Discover: Designers try to gather insights about the problem. • Define: Designers develop a clear briefthat frames the design challenge. • Develop: Solutions or concepts are created, prototyped, tested, and iterated. • Deliver: The resulting project is finalized, produced, and launched.

Explain understanding the user space?

Understanding the userspace involves: -Exploring(What is the current user experience? and Why is a change needed? -Articulating the problem space(Team effort and exploring different perspectives)

What are the principles of user-centered approach?

User centered approach is based on the principles: •Early focus on users and tasks: directly studying cognitive, behavioral, anthropomorphic, and attitudinal characteristics •Empirical measurement: users' reactions and performance to scenarios, manuals, simulations, and prototypes are observed, recorded, and analyzed •Iterative design: when problems are found in user testing, fix them and carry out more tests

How to find users needs?

Users needs can be found by: -Exploring the problem space -Investigating who are the users are -Investigating user activities to see what can be improved -Try out ideas with potential users Focusing on peoples' goals, usability, and user experience goals, rather than expect stakeholders to articulate requirements

What are the activities involved in interaction design?

Activities involved in interaction design: -Designing alternatives -Discovering requirements -Evaluating -Prototyping

Explain the degrees of user involvement?

Degrees of user involvement: -Member of design team -Face-to-face group or individual activities -Online contributions from thousands of users -User involvement after product release

Explain the importance of involving users?

Importance of involving users: -Expectation management(Realistic expectations and no surprises, no disappointments) -Ownership(Make the users active stakeholders which can make a big difference in acceptance and success of product
