Interaction Design
Some products are designed with the user in mind, some are engineering just to perform a set of
functions
Goal is to elicit positive responses from users and reduce negative aspects
Interaction Design: designing interactive products to support the way people communicate and
interact in their everyday working lives
Knowing the users
1.
Knowing the technology
2.
Knowing the methodology
3.
Key Elements of Interaction Design
Labels and control buttons look the same in an elevator
•
Need to push a button to activate bill reader on vending machine
•
Hotel phone has many steps to access voicemail system
•
Examples of bad design
Who the users are and their comfort level
○
What activities are being done
○
Where the interaction is taking place
○
Take into account
•
Optimize the interactions so the they match the users' activities and needs
•
How to do good design
Take into account what people are good and bad at
•
Consider how to help people in the way they currently do things
•
Think about what might provide quality user experiences
•
Listen to what people want and get them involved
•
User tried and tested user-centered methods
•
How to understand users' needs
Every interactive system is a distributed system running on two processers, the human user
and the computer user
•
UI design specifies/constrains both user and system behaviour
•
Dual Processor Theory
Class (manager, salesperson, shipper, client etc…)
•
Personality Type
•
Ability
•
Users can be categorized by:
User productivity = functionality of computer * usability by user
Kind and number of tasks
•
Characteristics of user
•
Work environment
•
Training and documentation
•
Functionality and usability of software and hardware
•
Factors influencing user productivity

Document Summary
Some products are designed with the user in mind, some are engineering just to perform a set of functions. Goal is to elicit positive responses from users and reduce negative aspects. Interaction design: designing interactive products to support the way people communicate and interact in their everyday working lives. Labels and control buttons look the same in an elevator. Need to push a button to activate bill reader on vending machine. Hotel phone has many steps to access voicemail system. Who the users are and their comfort level. Optimize the interactions so the they match the users" activities and needs. Take into account what people are good and bad at. Consider how to help people in the way they currently do things. Think about what might provide quality user experiences. Listen to what people want and get them involved. Every interactive system is a distributed system running on two processers, the human user and the computer user.
