Summary
This paper outlines a research plan for developing an adaptive, user-centered multimodal interaction framework for referencing external objects from a moving vehicle. The work addresses the limitations of current automotive interfaces, which often rely on "one-model-fits-all" approaches that fail to account for individual driver behaviors and the dynamic, safety-critical nature of driving. While existing research has explored multimodal fusion (combining gestures, gaze, and speech) for in-vehicle tasks, there is a gap in understanding how to reliably reference objects outside the vehicle while driving. The author aims to bridge this gap by creating a system that enhances trust and reliability through personalization and continuous learning, aligning with Human-Centered Artificial Intelligence (HCAI) principles. The proposed methodology follows a multi-stage approach. First, the research investigates driver behavior variances by analyzing performance and timing metrics for individual modalities, such as pointing gestures and eye gaze, to categorize drivers into behavioral clusters. Second, it develops an end-to-end multimodal fusion framework using machine learning algorithms. This includes comparing early, late, and hybrid fusion techniques that exploit temporal dependencies between modalities. Third, the plan incorporates adaptation techniques, specifically transfer-of-learning, to generate personalized models. This involves training a generalized model on a broad dataset and then fine-tuning it on individual user data to optimize performance for specific drivers. Finally, the research proposes a continuous learning mechanism that adapts to changes in driver state (e.g., cognitive load, emotion) through implicit and explicit feedback. Preliminary results, published in prior works, demonstrate the viability of these adaptation strategies. Clustering analysis revealed distinct groups of drivers based on pointing and gaze accuracy, allowing for cluster-specific model adaptation. Transfer-of-learning experiments showed that personalized models significantly outperformed generalized models in object referencing accuracy, measured by Root Mean Square Error (RMSE). Specifically, emphasizing individual training data within the generalized model’s training set improved performance, whereas simple 1:1 data mixing was insufficient. These findings validate the hypothesis that user-specific adaptation enhances system reliability. The significance of this work lies in its contribution to reliable and trusted automotive interfaces. By moving beyond static, generic models, the proposed framework offers design insights for multimodal interaction that account for individual differences and situational variability. The research provides an open-source framework for adaptive models and publishes datasets to support reproducibility. Ultimately, this approach aims to reduce driver cognitive load and improve safety by ensuring that vehicle interfaces adapt seamlessly to the user’s unique behavior and current mental state, thereby advancing the field of Human-Centered AI in automotive applications.
