Hager Intercom Outdoor

Software

Summary

On this hardware/software project, I supported the team in the UX/UI validation of the interface of a connected intercom, integrating facial recognition. My role was to verify graphic consistency, the behavior of micro-interactions, and to design the animations informing the user of the state of recognition.

Context

Product : Connected video intercom with touch screen and facial recognition
Company : Hager
Target users : Residents, visitors, installers
Challenges :
- Ensure consistency between the device screens and the design system guidelines
- Create a clear, smooth, and reassuring experience during facial recognition
- Ensure intuitive handling for varied user profiles

Problems to solve

Discrepancies between the mockups and the final implementation on the device
Lack of visual feedback during facial recognition
Translation or terminology inconsistencies between language versions

Methodology

Research and Inspiration :
- Study of competing intercom interfaces
- Observation of real usage on pilot site
Ideation and Prototyping :
- Definition of micro-interactions by scenario (successful recognition, failure, waiting)
- Creation of simple and explicit animations with Lottie
- Graphic harmonization with other Hager products
Collaboration & Tools :
- Work on Figma and Lottie files
- Functional reviews with developers and QA testers
- Use of Lokalise for multilingual validation
Testing and Iterations :
- Display and readability tests in outdoor conditions
- User feedback during internal demonstrations

Results & Impact

Deliverables :
- Validated screens with animated micro-interactions
- Documented UX behaviors for development
Impact :
- Better understanding of the system status for end users
- Reduction of interaction errors and the need for assistance
Feedback :
- A great opportunity to work at the intersection of industrial design and digital design, with a strong impact on tangible user experience.
