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
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
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.
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.
