Vehicle central screen

Embedded software

Summary

I conducted a series of qualitative user tests to evaluate different interfaces embedded in a vehicle prototype. The aim was to validate comprehension, ease of use, and user preferences to guide design choices.

Context

  • Product : Prototype interface for central screen and dashboard

  • Company : Faurecia

  • Target users : Representative test drivers of everyday use

  • Issues :

    • Assess the effectiveness and intuitiveness of the proposed interfaces

    • Gather qualitative data in the concept phase

    • Identify user preferences among several options (A/B/C)

Problems to solve

  • Uncertainties about the clarity of the proposed pathways

  • Difficulty in predicting user behaviors without real testing

  • Need for user data to guide product choices

Methodology

  • Research and Inspiration :

    • Review of cognitive ergonomics principles in driving

    • Comparative analysis of competing embedded interfaces

  • Test Organization :

    • Writing scenarios and questionnaires

    • Selection of a diverse panel (age, experience, type of driving)

    • Conducting A/B/C tests with observation of behaviors

  • Analysis :

    • Compilation of verbatims and behavioral measures

    • Definition of recommendations by tested interface

Results & Impact

  • Deliverables :

    • Comprehensive analysis report

    • UX recommendations integrated into the final project

  • Impact :

    • Improvement in the fluidity of user journeys

    • Better adherence of target users to the proposed choices

  • Feedback :

    • A very educational project that strengthened my interest in user testing in a semi-controlled environment.
