This thesis explores the potential and complexities that arise from the integration of wearable technology with connected vehicles. With the rise of hyper-connected lifestyles, wearable devices like smartwatches, smart bands, and fitness trackers are not only ubiquitous but are also collecting valuable biophysical data that can potentially enhance driver and passenger safety and comfort. Likewise, vehicles have evolved beyond mere transportation modes, transforming into sophisticated, sensor-laden, communication-enabled systems. Despite their distinct advancements, little research has engaged with the interconnectivity of heterogeneous wearable devices with third-party systems, particularly connected vehicles. To bridge this research void, this work presents a novel wearable-vehicle integration platform. Through a systematic three-phased methodology encompassing exploration, conceptualization, and experimentation, an innovative architecture emerges. Designed with components such as the device layer, device manager, service proxy, and backend connector, it not only addresses the fragmentation problem identified through technical market research in the exploration phase but also aspires to foster a cohesive ecosystem for varied wearable manufacturers. By promoting a unified ecosystem for wearables and connected vehicles, the proposed architecture not only promises enhanced user experiences and safety measures but also paves the way for manufacturers to exploit a broader spectrum of wearable data. Consequently, industries and end-users are expected to benefit from more personalized, efficient, and interconnected vehicular systems. Insights from this study underline that the challenge of wearable-vehicle integration is multidimensional. It is not just about bridging technological divides; it is also about navigating the dynamic business landscapes, vendor challenges, and overarching safety and security considerations. As technological frontiers expand, the findings of this research stand foundational, laying a groundwork for future innovations and studies in wearable technology and vehicular interconnectivity.
