uxlearn

An R Package for Learning User Experience

DOI

Learn UX. Measure Experience. Design Better.

Website and documentation: https://pablosancheznunez.com/uxlearn/

uxlearn is an open-source R package designed to support the teaching and learning of User Experience (UX) through practical exercises, usability metrics, data analysis, and reproducible simulations.

The package provides accessible tools for exploring how users interact with digital products and services, interpreting usability results, and understanding the principles behind UX evaluation.

Features

1. UX Metrics

Calculate and explore fundamental usability indicators:

  • Task success rate
  • Task completion time
  • Error rate
  • System Usability Scale (SUS) score

2. Usability Analysis

Analyse usability studies through descriptive summaries:

  • Overall study performance
  • Results by task
  • Results by task difficulty
  • Results by participant experience

3. UX Study Simulation

Generate reproducible synthetic usability studies to explore relationships between:

  • Participant experience
  • Task difficulty
  • Task success
  • Completion time
  • User errors
  • Satisfaction

4. Educational Dataset

uxlearn includes a synthetic usability dataset with 150 observations across 30 participants and five tasks.

The dataset contains participant profiles, task characteristics, success outcomes, completion times, errors, and satisfaction scores.

All simulated observations are synthetic and do not represent real users.

5. UX Learning Exercises

Generate structured exercises at beginner, intermediate, and advanced levels. Students can explore usability results, task-level analysis, interpretations, and questions designed to develop their UX evaluation skills.

exercise <- ux_learning(
  data = usability_test,
  level = "intermediate"
)
exercise$results
exercise$task_analysis

6. UX Recommendations and Case Studies

Explore data-driven recommendations and practical UX case studies across e-commerce, digital banking, online education, and e-government.

ux_recommendations(usability_test)
ux_case_study(domain = "education", level = "beginner")

7. Educational Materials

uxlearn includes an educational workbook and an answer key to support independent learning and practical classroom activities. ## Installation

uxlearn is currently under development and is not yet available on CRAN.

Install it from GitHub:

# install.packages("remotes")
remotes::install_github("pablosancheznunez/uxlearn")

Getting started

Load the package:

Calculate task success rate 

success <- c(1, 1, 0, 1, 0, 1)

ux_task_success(success)

Calculate task completion time 

times <- c(45, 52, 61, 38, 70, 49)

ux_task_time(times)

Calculate error rate 

ux_error_rate(
  errors = 8,
  opportunities = 40
)

Calculate a SUS score 

responses <- c(4, 3, 4, 2, 5, 3, 4, 2, 5, 3)

ux_sus_score(responses)

Simulate a usability study 

study <- ux_simulate_study(
  n_participants = 30,
  seed = 2026
)

head(study)

Summarise usability results 

results <- ux_usability_summary(study)

results$overall
results$by_task
results$by_difficulty
results$by_experience

Educational purpose

uxlearn aims to make UX evaluation more accessible to students, educators, and researchers.

Its educational approach combines:

  • Learning by doing.
  • Reproducible data analysis.
  • Practical interpretation of usability metrics.
  • Exploration of user behaviour through simulated studies.
  • Critical understanding of UX evaluation methods.

The package is intended as an open educational resource that can be used in university courses, workshops, and independent learning.

Accessing the learning materials

The UX Learning Workbook and its Answer Key can be read online in the Learning materials section of the website. They are also included in the package. Use ux_learning_materials() to locate the files:

# List all educational materials
ux_learning_materials()

# Open the workbook
ux_learning_materials("workbook", open = TRUE)

# Open the answer key
ux_learning_materials("answer_key", open = TRUE)

Development status

uxlearn is under active development.

The current version includes initial usability metrics, descriptive analysis functions, a synthetic educational dataset, and a reproducible usability study simulator.

Automated tests are used to check the reliability of the implemented functions.
