I-Jogging：基於震動回饋穩定步頻以增進跑步效率的穿戴式系統

Abstract

健康，對於現代人是一個相當重要的課題，而維持健康不外乎就是良好的飲食、充足的睡眠以及規律的運動。而要維持最規律運動最沒有成本以及最沒有門檻的就是跑步了。其中，穩定步頻為跑步中極為重要的元素。因此，本研究基於震動回饋穩定步頻以增進跑步效率，設計出 I-Jogging，由智能互動襪及手機應用程式所組成的穿戴式系統。\n本研究欲達成的目標為：讓使用者能在獨自一人的情況下，有穩定的頻率作為步頻跟隨的標準；使用裝置時減少對裝置的注意力，增加跑步時的安全性；使用裝置時不會因為額外過多的重量而影響跑步效率；可以自行調整震動頻率以符合自身跑步需求。上述目標旨於設計出一種新型態、增加使用裝置時安全性且用於跑步之穿戴式裝置。未來亦可望將此一方法擴大運用於其他運動中。\n本研究採觀察法及訪談法，實作 I-Jogging 穿戴式系統中的智能互動襪及手機應用程式作為原型工具。在經過三次系統迭代後，徵集五位受試者進行測試。實驗後發現，震動作為受試者跟隨步頻之依據是有效果的，能讓受試者輕易的穩定步頻。除此之外，手機應用程式步頻紊亂提示能清楚告訴使用者需要修正步頻，可以在跑步途中任意調整頻率，使得使用者也可以依據自身需求自行調整，震動回饋之於提升跑步效率是明顯有成效的。

Health and fitness are important to modern people. Main approaches for health and fitness include a good diet, adequate sleep, and regular exercise. Among these practices, jogging is one of the most popular approaches as it is with low cost and low barrier. For jogging, stabilizing stride frequency is the key to the effectiveness of the exercise. In this thesis, the author aims to investigate the design of a wearable system that helps the runner to maintain stable stride frequency based on vibration feedback devices. The prototype of the proposed design is called I-Jogging, which is a system with smart interactive socks and an App for mobile phones. The goal of this system is to assist the user to have a stable frequency without paying too much attention to the system. The smart interactive sock is made using conductive thread so that it is lightweight and does not affect running efficiency. Moreover, users can adjust the vibration frequency by themselves to meet their running needs.\nThe prototype went through three system iterations. To evaluate the prototype, this research follows the observation and the interview methods simultaneously. The results indicate that vibration feedback is effective for users to follow the stride frequency, allowing users to easily stabilize the stride frequency. In addition, the mobile phone application stride frequency disorder prompt can tell the user that the stride frequency needs to be modified, and the frequency can be adjusted dynamically when jogging. In this way, the user can also adjust stride frequency according to their own needs.
