while others are highly frustrating?
Why are some objects easy to interact with,
Principles of Design
the process of making artifacts that will be used by people.
the artifacts you make.
Purpose of Design:
to transform the world from the
In relation to Art:
the making of artifacts that will be used to stimulate reflective thought and emotion
In relation to Engineering:
the application of science and mathematics to solve human problems
Seven Stages of

Apply to playing an instrument. Fill in each stage.
Mental representation of how an object works and why it works that way.
Approximate, incomplete, and evolving!
How does the Focusrite 2x2 work?
“... refers to the perceived and actual properties of the thing, primarily those fundamental properties that determine just how the thing could possibly be used. A chair affords support and, therefore, affords sitting.” [DOET, page 9]
Allowable actions perceived from "clues"

Effective clues convey correct set of actions
1. From relations between actions and outcomes
2. Follow cultural standards
3. Leverage physical analogies
How do Max objects leverage physical analogies?
conveying what action has been done and what the result was
Physical limitations constrain actions
Meaning of situation constrains actions
Relies on accepted conventions
When all else fails...
Reduces cognitive load on user
Reduces learning time
Improves adaption to new situations
Fewer things to memorize

UI Design Checklist
• Put all information in the interface
• Surface the conceptual model
• Use constraints
• Follow standards
• Design for error
• Provide affordances
• Make controls visible
• Use effective mappings
Facilitate transfer of mental models
Borrow vocabulary and actions from physical world to describe abstract concepts
Interface Metaphors in Music Tech?
Do they work?
Should they go here?
Are they evident?
Is there a better one?
What is this?
Why does it work?
Actions determined by reason
errs, they need
Especially when the user causes errors!
