This document provides an introduction to interaction design. It defines interaction design and outlines its key stages and practices. It discusses personas, which are archetypal user descriptions used to guide design. Scenarios and user stories are also examined - scenarios describe how users might interact with a system, while user stories outline sequences of actions and events. The document uses examples to illustrate how personas, scenarios, and user stories are written and applied in the design process.

6. Interaction Design
• The practice of designing interactive digital
products, environments, systems, and services
• Focuses on understanding the goals and needs of
users and trying to design tools for users to
achieve those goals
• Taking into account a user's environment and
technological limitations
• Defining the structure and behavior of interactive
systems

9. Developing Personas

10. Personas
• A description of a user archetype that can
serve as a guide to the design process
• Composed from a series of field activities
such as interviews and observations
• The descriptions are summarized in 1-2
pages

11. Use of Personas in
Design
• Designers use personas when it is not
possible or practical to turn to users
• Personas cannot substitute involving real
users in the design process

13. Writing Scenarios

14. Scenarios
• A narrative describing foreseeable
interactions of types of users (characters) and
the system
• Include information about goals, expectations,
motivations, actions and reactions
• Attempts to reflect on or portray the way in
which a system is used in the context of daily
activity

15. Example
It’s Friday afternoon and Joe is flying to Sydney. He
doesn’t have enough money for a taxi to the airport
and he’s running late.
He goes to a local ATM and identifies himself.
He specifies that he wants $100 from his savings
account. He’d like the money in $20 notes so that
he can give the taxi driver the correct change.
He doesn’t want a printed receipt, as he doesn’t
bother keeping track of transactions in his account.

16. Writing User Stories

17. User Stories
• Descriptions of a sequence of actions and
events that lead to an outcome
• Each user story is limited, and should fit on
a small paper note/card to ensure that it
does not grow too large
• A quick way of handling customer
requirements

18. Examples
• "As a <role>, I want <goal/desire> so that
<benefit>"
• As a user, I want to search for my
customers by their first and last names so
that I can find customers faster.
