When My Car Whispers Secrets to My Home: Envisioning the Opportunities and Challenges of Human-Vehicle-Home Integrated Ecosystems through Probes

This paper explores the concept of human-vehicle-home (HVH) integrated intelligent experiences and its potential to transform everyday life through seamless connectivity between smart vehicles and smart homes.While existing research has largely focused on technical advancements, this study adopts a human-centered approach to uncover the design opportunities and socio-technical challenges inherent in HVH systems.Using a probe-based method, we engaged eight participants from diverse living conditions across China to envision future scenarios of HVH integration, capturing their expectations, concerns, and values.Our findings highlight the potential of HVH systems in enhancing cross-space well-being, fostering continuums in activity and memory, and strengthening interpersonal support, particularly within families.However, participants also identified critical challenges, including privacy risks, safety concerns, mismatches in technological literacy, and usability disparities across regions.This work provides the first exploration of HVH systems and design implications that move beyond technical advancement to prioritize human needs and values, as well as embrace the diversity of communities and lifestyles.
