This study explores the integration of blockchain technology in wearable health devices through the design and development of a Smart Fidget Toy. We aimed to investigate design challenges and opportunities of blockchain-based health devices, examine the impact of blockchain integration user experience, and assess its potential to improve data control and user trust. Using an iterative user-centered design approach, we developed a mid-fidelity prototype of a physical fidget device with a blockchain-based web application. Our key contributions include the design of a fidget toy using blockchain for secure health data management, an iterative development process balancing user needs with blockchain integration challenges, and insights into user perceptions of blockchain wearables for health. We conducted user studies, including a survey ( = 28), focus group ( = 6), interactive wireframe testing ( = 7), and prototype testing ( = 10). Our study revealed high user interest (70%) in blockchain-based data control and sharing features and improved perceived security of data (90% of users) with blockchain integration. However, we also identified challenges in user understanding of blockchain concepts, necessitating additional support. Our smart contract, deployed on the Polygon zkEVM testnet, efficiently manages data storage and retrieval while maintaining user privacy. This research advances the understanding of blockchain applications in health wearables, offering valuable insights for the future development of this field.
这项研究通过设计和开发一款智能手指陀螺玩具，探索了区块链技术在可穿戴健康设备中的集成。我们旨在调查基于区块链的健康设备的设计挑战和机遇，研究区块链集成对用户体验的影响，并评估其提高数据控制和用户信任的潜力。我们采用迭代的以用户为中心的设计方法，开发了一个具有基于区块链的网络应用程序的物理手指陀螺的中保真原型。我们的主要贡献包括使用区块链设计用于安全健康数据管理的手指陀螺玩具、平衡用户需求和区块链集成挑战的迭代开发过程，以及对用于健康的区块链可穿戴设备的用户感知的深入了解。我们进行了用户研究，包括一项调查（n=28）、一个焦点小组（n=6）、互动线框测试（n=7）和原型测试（n=10）。我们的研究表明，用户对基于区块链的数据控制和共享功能非常感兴趣（70%），并且区块链集成提高了用户对数据安全性的感知（90%的用户）。然而，我们也发现用户对区块链概念的理解存在挑战，需要提供额外的支持。我们的智能合约部署在 Polygon zkEVM 测试网上，有效地管理数据存储和检索，同时保护用户隐私。这项研究推进了对健康可穿戴设备中区块链应用的理解，为该领域的未来发展提供了有价值的见解。
