Study Notes

Evaluation

Evaluation is a crucial part of the design process.
It involves gathering and analyzing data about user experiences with a design.
The goal is to enhance the design and ensure a positive user experience.

Why Evaluate?

User experience encompasses all aspects of interaction with a product.
Modern users expect more than just functional systems.
Well-designed products tend to be successful in the market.

What to Evaluate

Evaluation applies to a wide range of design aspects.
This can include prototypes, complete systems, specific features, entire workflows, and aesthetic elements.

Where to Evaluate

The location of evaluation depends on the specific aspect being assessed.
Lab settings are advantageous for controlled investigations of certain characteristics, like web accessibility.

When to Evaluate

The timing of evaluation depends on the development stage and product type.
Formative evaluations are conducted during the design process to ensure ongoing user satisfaction.
Summative evaluations assess the success of a finished product.

Types of Evaluation

There are three main categories of evaluation methods.

Controlled Settings with Users

These methods directly involve users in a controlled environment, such as usability labs.
Users' activities are carefully monitored to test hypotheses and measure specific behaviors.
Key methods include usability testing and experiments.

Expert Reviews

Experts leverage their knowledge and experience to identify potential problems and design flaws.

Heuristic Evaluation

Experts analyze a design based on established principles and guidelines.
Multiple experts independently review the design and document issues.
It involves identifying heuristics and finding solutions.

Usability Engineering

A quick evaluation method focusing on usability criteria like learnability, effectiveness, and satisfaction.
Provides rapid feedback for design improvements.

Cognitive Walkthrough

A thorough paper-based technique for evaluating the design logic and user interaction steps.
Based on cognitive theories and detailed documentation of the interface.
Focuses on ensuring users can successfully complete tasks.

Participant Methods

Involve real users representative of the target audience.
Aim to gather insights from genuine user interactions.

Participant Evaluation

Allows for various degrees of user involvement in the evaluation process.
Ranges from observing users working with the system to leaving them to explore independently.

Cooperative Evaluation

Users actively participate as co-evaluators, contributing to the data collection process.

Participatory Heuristic Evaluation

Incorporates user input as domain experts alongside usability experts.

Co-discovery

A naturalistic approach that captures initial user impressions.
Focuses on observing users' interactions with the system.

Controlled Experiments

Useful for comparing different design variations.
Quantitative data is collected to measure the effectiveness of each design.

Metrics and Measures

Usability metrics like effectiveness, efficiency, and satisfaction help in evaluating applications.

Guidelines from Perception

Gestalt principles of perception provide insights for organizing visual elements in interfaces.
These include proximity, similarity, continuity, and closure.

Principles from Memory and Attention

Short-term memory capacity is limited.
Chunking helps optimize information processing for working memory.
Timeliness is crucial for preserving information in short-term memory.
Recall and recognition play roles in information retrieval.

Navigation design is a key aspect of information architecture.
Important features include labeling, navigation support, and search mechanisms.

Web Analytics

Tracks user behavior and website performance.
Provides data for optimizing website design and functionality.
