The process of interaction design
Evaluating the design
(is the process of determining the usability and acceptability of the product or design)
The most sensible way for users to evaluate such designs is to interact with them
This is the core activity of desiging
Involves producing the
for the product
Conceptual model: describes an abstraction outlining what people can do with a product and what concept are needed to understand how to interact with it
considers the detail of the product including colors, sound and images
Focus attention on users and their goals
Involving users in the development
Is the process of making sure that users expectations of the new product are realistic
Degrees of the user involvement
Co-opted (major contributors)
limited time only
the real users and their goals are the driving force behind product development
Early focus on users and tasks
undestanding the user behavior, tasks etc
Users 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 thorought development
All design decisions are taken within the context of the users
observation of the user and their reaction for different scenarios
Redesigning after each problem found
Lifecycle model for interaction design
Rinse and repeate until the product is complete in the best possible way
Who are the users?
What do we mean by needs?
What are they trying to achieve, how they achieve it currently and whether they would achieve their goals more effectively and have a more enjoyable experience if they were supported differently
How do you generate alternative designs?
Very little in this world is completely new
Cross-fertilization may result by discussing ideas with other designers
Seeking different perspectives and looking at other designs
How do you choose among alternatives?
By letting users and stakeholders interact with them and by discussing their experiences, preferences, and suggestions for improvement
How do you integrate interaction design activities with other lifecycle models?
