Abstract

In recent years, with the increasing use of bicycles for environmental and health benefits, the importance of the feedback for cyclists is increasing. Moreover, as bicycles account for 23 % of all traffic accidents in 2022, improving bicycle safety is a crucial challenge. This study aimed to explore methods for enhancing safety and improving feedback to cyclists through auditory and tactile signals. Experiments were conducted using a cycling simulator and cross-modal reaction tests of tactile and auditory signals to simulate bicycle riding under actual external noise environments. The accuracy of the recognition and reaction times for both tactile and auditory signals were evaluated in situations with simulated road traffic sounds. Subsequently, the effectiveness of cross-modal feedback was assessed, optimal signal conditions were examined, and the relationship between variations in environmental noise and optimal auditory signals for cyclists was discussed. The results showed that cross-modal feedback led to faster reaction times, while the recognition accuracy of auditory signals varied depending on environmental noise levels. The present findings suggest the potential of cross-modal feedback to enhance cyclist safety, particularly when optimized for environmental conditions and individual perception.

在嘈杂环境中为骑车者提供触觉和听觉刺激的跨模态反馈

近年来，随着人们越来越多地使用自行车来保护环境和健康，对骑车人的反馈意见也越来越重要。此外，由于 2022 年自行车交通事故占所有交通事故的 23%，因此提高自行车的安全性是一项至关重要的挑战。本研究旨在探索通过听觉和触觉信号提高安全性和改善对骑车人反馈的方法。实验使用了自行车模拟器以及触觉和听觉信号的跨模态反应测试，模拟实际外部噪声环境下的自行车骑行。在模拟道路交通声音的情况下，对触觉和听觉信号的识别准确性和反应时间进行了评估。随后，评估了跨模态反馈的有效性，研究了最佳信号条件，并讨论了环境噪声变化与骑车人最佳听觉信号之间的关系。结果表明，跨模态反馈可加快反应时间，而听觉信号的识别准确率则因环境噪声水平而异。本研究结果表明，跨模态反馈具有增强骑车人安全的潜力，尤其是在根据环境条件和个人感知进行优化的情况下。
