What is interaction design?
Designing interactive products to support people in their everyday and working lives
Sharp, Rogers and Preece (2002)
The design of spaces for munication and interaction
Winograd (1997)
Goals of interaction design
Develop usable products
Usability means easy to learn, effective to use and provide an enjoyable experience
Involve users in the design process
Example of bad and good design
Elevator controls and labels on the bottom row all look the same, so it is easy to push a label by mistake instead of a control button
People do not make same mistake for the labels and buttons on the top row. Why not?
From:
Why is this vending machine so bad?
Need to push button first to activate reader
Normally insert bill first before making selection
Contravenes well known convention
From:
What to design

Who the users are
What activities are being carried out
Where the interaction is taking place
What the user believes about the interaction
Need to optimise the interactions users have with a product
Such that they match the users’ activities and needs
Understanding users’ needs
Need to take into account what people are good and bad at
Consider what might help people in the way they currently do things
Listen to what people want and get them involved
Use tried and tested user-based methods
