Study Notes

Interaction Design and the User Experience

Interaction design involves understanding users and their primary objectives, such as designing an efficient system or a learning tool.

Objectives of Interaction Design

Classifying objectives into:
- Usability
- User Experience
- Goals

Usability Goals

Typically operationalized as questions to assess various aspects of an interactive product and the UX.
Purposes of usability goals:
- To provide a concrete means of assessing the design.
- To alert designers to potential design problems and conflicts early in the design process.

Breaking Down Usability Goals

Usability is broken down into the following goals:
- Effectiveness: ensuring the product does what it is supposed to do.
- Efficiency: supporting users in carrying out their tasks.
- Safety: protecting users from dangerous conditions and undesirable situations.
- Utility: providing the right kind of functionality.
- Learnability: how easy is the product to learn.
- Memorability: how easy is the product to remember how to use.

Effectiveness

Refers to how good a product is at doing what it is supposed to do.
Question: Is the product capable of allowing people to learn, carry out their work efficiently, access the information they need, or buy the goods they want?

Efficiency

Refers to the way a product supports users in carrying out their tasks.
Question: Can users sustain a high level of productivity once they have learned how to use the product?

Safety

Involves protecting users from dangerous conditions and undesirable situations.
Questions:
- What is the range of errors that are possible using the product?
- What measures are there to permit users to recover easily from them?

Safety (Ergonomic Aspects)

Refers to:
- Dangerous conditions: external conditions where people work (e.g., hazardous conditions).
- Undesirable situations: helping users avoid dangers of carrying out unwanted actions accidentally.

Utility

Refers to the extent to which the product provides the right kind of functionality.
Question: Does the product provide an appropriate set of functions that will enable users to carry out all their tasks?
