Everyday Frustrations
Fundamentals of
Interaction Design
Inventions and technologies
that transform the human condition

What is interaction design ?
Metaphors based on the physical world
Graph of intersecting disciplines
I can't understand my air conditioner
.....so what?!?
This can lead to an accident or death
U.S. Fire Administration says “Cooking equipment, most often a range or stovetop, is the leading cause of reported home fires and home fire injuries in the United States.”
4 Approaches to Design
User Centered
Designers help the user reach their intended goal
Fit products to people
Goal oriented
Activity Centered
Concerned with an activity, like learning a language, which might take a long time
Designers focus narrowly on the tasks at hand and design products and tools that support that task
Systems Centered
Focuses on the system, such as software, and the way it functions
Instead of tailoring the software to the user needs, the interface acts as a way to teach the user the system itself
The positive side of this is that it is a holistic approach to seeing the problem
Rapid Expert Design
Relies on the wisdom and experience of the designer
User testing is limited
Being reduced by ATM’s, Gas Pumps, and Alarm Clocks
Design Research

The Design Process
In a Nutshell
Information Architecture
Wireframes and
Paper Prototype Testing
Comps (Comparison Designs)
Coding, Refinement & Development
Concepts to help create
more effective designs
Locus of Attention
In his book, “The Design of Everyday Things” Donald Norman defines an affordance as something of both actual and perceived properties.
Cognitive Load
In his book “Flow”, Mihaly Csikszentmihalyi describes a state of optimal experience, where people are so engaged in the activity they’re doing that the rest of the world falls away. Flow is what we’re looking to achieve through engaging interactions. We should allow users to concentrate on their work, not on the user interface.
Seems like a
lot of work...
“Humans have an amazing tendency to become accustomed to the terrible, inconvenient, and awkward”
— Dan Saffer
You can bring humanity to computing. Interfaces projected in our real world, that interact with real world items
Current metaphors will become obsolete and need new solutions.

Thank you! And Quetions?
The future holds more interaction between humans, the physical world and the virtual world — we will need usable interfaces

To Conclude
For today, question your interactions
