ACCESSIBILITY & USABILITY
Looking at the retail industry to improve accessibility, usability and adherence to heuristic principles.
What's the problem?
Based the Louis Vuitton site, there are many issues which hinder the user's experience and make it difficult to complete the goals they set out with.
Who are the users?
The participants we recruited were female university students aged 25-34 years old as this was the most popular demographic who used the site (according to similarweb).
Why should we care?
Accessibility ensures that everyone, including those with any form of disabilities, can have the same experience as anyone else. This helps to improve brand status, company profit and overall user experience.
How did I test it?
Using the WAVE tool and manually checking features against the WCAG 2.2 guidelines.
Creating 3 tasks and carrying out usability assessments - measuring task time, task completion, errors made, lostness and SUS scale.
Heuristic analysis against the 10 core principles.
What did I find?
Quantitative data
Accessibility: 6 perceivable, 2 operable and 2 understandable errors.
Usability:
Task 2 - had the highest errors and exceeded task time set.
17% unacceptable SUS score values.
Task 3 Lostness exceeded threshold.
Qualitative data
Heuristics: Failure to meet principles #2, #4, #5, #7, #8 and #9.
4 main issues
Validating user information
Alternative text for images
Retaining previously searched items
Product organisation/layout
What's my solution?
Adding alt text to all images (WCAG 1.1.1)
Storing previous searches in memory (Heuristic #7)
Add text to category dividers (Dual coding)
Providing clear error messages (Heuristic #9)
