Understanding User Requirements for Creating Sensor-Powered Smart Car Cabins Through Retrofitting
Research with 33 participants uncovers design gaps in built-in car sensors, proposing retrofit solutions.
A team of researchers has published a forward-looking study, accepted for the prestigious CHI 2026 conference, that investigates how to upgrade existing vehicles with smart sensor technology. The paper, "Understanding User Requirements for Creating Sensor-Powered Smart Car Cabins Through Retrofitting," argues that aftermarket retrofitting presents a significant opportunity to complement and extend the often-limited capabilities of factory-installed smart cabin systems. This approach could democratize advanced features for owners of older or less-equipped vehicles.
To ground their proposals in real user needs, the authors conducted a rigorous two-phase study. First, they performed semi-structured interviews with 18 participants to identify the specific challenges and limitations of built-in smart cabin sensors. Following this, they engaged 15 different participants in probe-based participatory design sessions to collaboratively define user requirements and expectations for effective retrofit solutions. The culmination of this research is a concrete set of design recommendations intended to guide the future development of practical and user-centered retrofit kits for creating smarter car interiors.
- Study accepted to top-tier CHI 2026 conference, involving 33 participants across two research phases.
- Identifies gaps in manufacturer-built smart cabin sensors, proposing retrofitting as a complementary solution.
- Delivers actionable design recommendations for developing user-centered aftermarket smart cabin upgrade kits.
