Flexible sensors, friendly interfaces, and intelligent recognition are important in the research of novel human-computer interaction and the development of smart devices. However, major challenges are still encountered in designing user-centered smart devices with natural, convenient, and efficient interfaces. Inspired by the characteristics of textile-based flexible electronic sensors, in this article, we report a braided electronic cord with a low-cost, and automated fabrication to realize imperceptible, designable, and scalable user interfaces. The braided electronic cord is in a miniaturized form, which is suitable for being integrated with various occasions in life. To achieve high-precision interaction, a multi-feature fusion algorithm is designed to recognize gestures of different positions, different contact areas, and different movements performed on a single braided electronic cord. The recognized action results are fed back to varieties of interactive terminals, which show the diversity of cord forms and applications. Our braided electronic cord with the features of user friendliness, excellent durability and rich interaction mode will greatly promote the development of human-machine integration in the future.
灵活的传感器、友好的界面和智能识别在新型人机交互和智能设备的发展中非常重要。然而，在设计以人为中心的智能设备时，仍然面临着自然、方便和高效接口的重大挑战。受纺织基柔性电子传感器特性的启发，本文报道了一种编织电子线，它具有低成本和自动化制造的特点，可实现隐形、可设计和可扩展的用户界面。编织电子线采用微型化形式，适合集成到生活中的各种场合。为了实现高精度交互，设计了一种多特征融合算法，以识别单个编织电子线上不同位置、不同接触面积和不同运动的手势。识别的动作结果反馈到各种交互终端，展示了线绳形式和应用的多样性。我们的编织电子线具有用户友好、出色的耐用性和丰富的交互模式等特点，将极大地促进未来人机一体化的发展。
