User Testing Lab

We've created our User Testing Lab: an evaluation framework...

We believe that legal innovation through design is the key to legal efficiency. But beyond words, we are passionate about KPIs and tangible results.

Mathilde Amurabi

With Mathilde da Rocha, PhD in cognitive neuroscience, we have developed a testing methodology adapted to legal documents based on internationally recognized standards.

Our Lab allows us to perform expert audits, user tests, online accessibility tests (taking into account color blindness for example) and usability tests.

Our evaluation methods

We apply two methods: expert evaluation and user testing. Combined, these methods allow us to evaluate the quality of legal documents according to the user characteristics and their information needs, tasks, and environment.

Evaluation
expert

This method applies to
object characteristics

' It consists of evaluating the artifact by focusing on the experience of the evaluators (without direct involvement)

' It helps to identify potential interaction problems

It concludes with concrete recommendations

Often used in addition to user testing because it is more cost-efficient,
this evaluation is done without users. We rely on internationally recognized criteria such as Scapin & Bastien (1997) and Nielsen's heuristic principles to evaluate the way users interact with legal documents, taking into account their individual biases.

Tests
users

This method requires
the direct participation
of users

' It consists in putting a sample of users in a situation of use of the artifact

During the test, objective and subjective measures are collected

' Analyses allow us to confirm or refute the initial hypotheses

We evaluate the accessibility of documents using readability tests such as Flesch, Gunning Fog, ARI, Coleman Liau, and SMOG. Beyond all of these acronyms, the method is fairly simple: we measure the level of education needed to understand a text on first reading, based on sentence length, sentence density, and word length.

Why have your documents tested at
?

Improve

Evaluate the design with users to improve solutions based on their feedback

Minimize risk

Submit a prototype during development to minimize the risk that the document will not meet user or organizational requirements

Prioritize

Obtain data to define and prioritize areas for intervention

User test example

Test carried out for the CNIL within the framework of cookies settings.

Comprehensibility: Average

The children were again very receptive to the content of the prototype and the issues involved. However, the analogy and link to the illustrations was questioned. The analogy with the crystal ball led to misunderstandings among the participants.
The ease of use is good (except for the home screen where the guidance can be improved). The illustrations contribute to the pleasure of using the prototype.

"It's good that they're taking a little bit of interest in us because it's not always safe"
"It's not clear enough because of the crystal ball, I don't understand why we're talking about this with cookies"

"I always say no to ads. So I click on "refuse all".

Conclusion: the term "crystal ball" creates confusion, but the hero of the game and the illustrations promote acceptability.
Prototype to be abandoned, in favor of the n°2 of 15-17 (restructured video plus action buttons, without the quiz that did not work well).
