📝 摘要(中文)

随着汽车工业向自动化和半自动化车辆的快速发展,传统的车辆交互方法(如触摸和语音命令)已无法满足日益增长的非驾驶相关任务需求,如引用车外物体。因此,研究逐渐转向手势输入(如手势、视线和头部姿态)作为更适合的交互方式。然而,由于驾驶的动态特性和个体差异,驾驶者的手势输入表现存在显著差异。为了解决这一问题,本文提出了一种名为IcRegress的新型基于回归的增量学习方法,能够适应驾驶者在驾驶和引用物体的双重任务中的行为变化和个体特征。我们的方法通过持续的终身学习来增强驾驶体验、安全性和便利性,并在车外物体引用的使用案例中进行了评估,显示出增量学习模型在不同驾驶者特征下的优越性。最后,我们将该方法作为开源框架提供,以促进可重复性和进一步研究。

🔬 方法详解

问题定义:本文旨在解决现有单实例训练模型在个体驾驶者手势输入表现上的适应性不足问题。这些模型无法有效应对驾驶者行为的动态变化和多样化的驾驶场景。

核心思路:IcRegress采用增量学习的方法,能够在驾驶过程中持续适应驾驶者的个体特征和行为变化,从而提供更个性化的交互体验。通过这种设计,系统能够在不同驾驶条件下保持高效的物体引用能力。

技术框架:整体架构包括数据采集模块、增量学习模型和用户反馈机制。数据采集模块负责收集驾驶者的手势输入数据,增量学习模型则基于这些数据进行训练和更新,而用户反馈机制则用于优化模型性能。

关键创新:最重要的技术创新在于引入了增量学习的概念,使得模型能够在实际应用中不断学习和适应,区别于传统的静态训练模型,后者无法应对个体差异和环境变化。

关键设计:在模型设计中,采用了适应性损失函数和动态更新机制,以确保模型能够实时调整其参数。此外,网络结构设计上考虑了多模态输入的融合,以提升对手势输入的理解能力。

📄 摘要(原文)

The rapid advancement of the automotive industry towards automated and semi-automated vehicles has rendered traditional methods of vehicle interaction, such as touch-based and voice command systems, inadequate for a widening range of non-driving related tasks, such as referencing objects outside of the vehicle. Consequently, research has shifted toward gestural input (e.g., hand, gaze, and head pose gestures) as a more suitable mode of interaction during driving. However, due to the dynamic nature of driving and individual variation, there are significant differences in drivers' gestural input performance. While, in theory, this inherent variability could be moderated by substantial data-driven machine learning models, prevalent methodologies lean towards constrained, single-instance trained models for object referencing. These models show a limited capacity to continuously adapt to the divergent behaviors of individual drivers and the variety of driving scenarios. To address this, we propose \textit{IcRegress}, a novel regression-based incremental learning approach that adapts to changing behavior and the unique characteristics of drivers engaged in the dual task of driving and referencing objects. We suggest a more personalized and adaptable solution for multimodal gestural interfaces, employing continuous lifelong learning to enhance driver experience, safety, and convenience. Our approach was evaluated using an outside-the-vehicle object referencing use case, highlighting the superiority of the incremental learning models adapted over a single trained model across various driver traits such as handedness, driving experience, and numerous driving conditions. Finally, to facilitate reproducibility, ease deployment, and promote further research, we offer our approach as an open-source framework at \url{https://github.com/amrgomaaelhady/IcRegress}.
