Joule
Improving human-machine interaction thanks to user testing
Joule is a smart career companion using
Artificial Intelligence to make the job hunting process more efficient and, above all, more human.
Understanding the roots of the problem
One of Joule's key principles is the awareness that the classic Curriculum Vitae is now an outdated model, unable to create an authentic connection with candidates due to its anonymity. Therefore, on Joule's platform, a video presentation was incorporated in place of the traditional CV. This made easier the evaluation of soft skills easier, as they are better highlighted through video interactions.
Joule's team came to us with a question:
“Why are users hesitant to record video presentations on Joule?”
To find an answer to this question we did
five rounds of interviews with users, each one of the duration of a hour, and this gave us fundamental answers.
What did we discover?
The prevailing feeling that stopped the user from recording the video was the fear of AI.
Although AI is the distinctive strength of Joule, we found that many users were afraid of it. The data speaks out plainly:
0% of users understood the usage of AI in Joule, the 80% wouldn't have completed the profile and only the 20% of them had a positive feeling about AI (Joule aside).
Building trust:
prototyping and usability testing
We had an ambitious goal:
inspiring trust in the AI of Joule and make the video recording less intimidating.
Not simply testing
We took a guerrilla testing approach to test our app prototypes. As the name suggests, it's a fast and fun process that aims to collect a large amount of data on the usability of a digital product in a short time, in a public setting. Plus, we offered a reward that was impossible to refuse!
With the contribution of more than
70 testers we were able to validate our proposal, showing that our vision could lead to a
better experience for the user.
Tone of Voice and perception
We also played with the “Tone of Voice” of the images, trying to understand whether photographs or illustrations had a more positive impact on the feelings of reliability and humanity perceived by users. The result? A shift from illustrations to photos that hit the mark.
Glammed up
We finalized the changes in the app design, moving from illustrations to photos and paying particular attention to the copywriting: we tested the prototype again with about 35 online users using the Maze platform. The feedback was significantly more positive than the first tests.
Empathy as a key data interpretation
The heart of this project was to listen carefully to users, understand their fears and offer solutions that would improve their experience with Joule. A qualitative research approach guided every step, proving that listening and responding to users' feelings can lead to significant improvements and a more rewarding user experience.
