Abstract

In ballet, synchronizing movement with music is essential for both technical precision and expressive performance. However, younger dancers often struggle with abstract concepts such as timing due to the lack of continuous, personalized feedback in traditional instruction. This paper introduces KneeEcho Box, an interactive sonification interface for ballet training that uses real-time computer vision to track knee movements during the plié and translates them into MIDI-based xylophone tones, reminiscent of a music box. KneeEcho Box was evaluated in a between-subjects study with 22 young ballet dancers. Results show that sonification enhanced movement precision, spatiotemporal awareness, and user engagement, particularly among younger participants. These findings suggest that integrating interactive auditory feedback into ballet practice can enrich traditional instruction and open new avenues for research at the intersection of human–computer interaction and the performing arts.

膝回声盒：一个实时超声接口，用于提高芭蕾训练的时间精度

在芭蕾中，动作与音乐的同步对于技术精确性和表现力都是至关重要的。然而，由于传统教学中缺乏持续的、个性化的反馈，年轻的舞者经常在时间等抽象概念上挣扎。本文介绍了膝回声盒，这是一个用于芭蕾训练的交互式超声界面，它使用实时计算机视觉来跟踪膝盖运动，并将其转换为基于midi的木琴音调，让人联想到音乐盒。膝关节回声盒在22名年轻芭蕾舞者的受试者间研究中进行了评估。研究结果表明，声音增强了运动精度、时空意识和用户参与度，尤其是在年轻参与者中。这些发现表明，将交互式听觉反馈融入芭蕾舞练习可以丰富传统教学，并为人机交互与表演艺术的交叉研究开辟新的途径。

期刊介绍： The International Journal of Human-Computer Studies publishes original research over the whole spectrum of work relevant to the theory and practice of innovative interactive systems. The journal is inherently interdisciplinary, covering research in computing, artificial intelligence, psychology, linguistics, communication, design, engineering, and social organization, which is relevant to the design, analysis, evaluation and application of innovative interactive systems. Papers at the boundaries of these disciplines are especially welcome, as it is our view that interdisciplinary approaches are needed for producing theoretical insights in this complex area and for effective deployment of innovative technologies in concrete user communities. Research areas relevant to the journal include, but are not limited to: • Innovative interaction techniques • Multimodal interaction • Speech interaction • Graphic interaction • Natural language interaction • Interaction in mobile and embedded systems • Interface design and evaluation methodologies • Design and evaluation of innovative interactive systems • User interface prototyping and management systems • Ubiquitous computing • Wearable computers • Pervasive computing • Affective computing • Empirical studies of user behaviour • Empirical studies of programming and software engineering • Computer supported cooperative work • Computer mediated communication • Virtual reality • Mixed and augmented Reality • Intelligent user interfaces • Presence ...
