Particulate matter (PM) pollution is a serious issue in Korea, but people are not actively engaged in preventive actions. Therefore, this study aimed to develop a PM website that includes interactive features where users can easily learn PM information; further, we aimed to explore the effects of website interactivity on behavioral intentions. We conducted an online experiment with four versions of a website with differs regarding the presence/absence of menu customization and highlighter options. Data from 100 participants in South Korea showed that menu customization was effective in increasing the users’ sense of agency and their intentions to recommend the website, seek more PM information, and engage in the activities of the website owner. However, a highlighter tool was not a significant prompt for enhancing perceptual bandwidth and behavioral intentions. The findings of this study can contribute to the development of interactivity research and models and better website design.

在韩国，颗粒物（PM）污染是一个严重的问题，但是人们并未积极地采取预防措施。因此，本研究旨在开发一个包含交互功能的PM网站，使用户可以轻松地学习PM信息。此外，我们旨在探讨网站互动对行为意图的影响。我们对网站的四个版本进行了在线实验，网站的四个版本在菜单自定义和荧光笔选项的存在与否方面有所不同。来自韩国100个参与者的数据显示，菜单自定义可以有效地提高用户的代理意识以及他们推荐网站，寻找更多PM信息以及参与网站所有者活动的意图。然而，荧光笔工具并不是增强感知带宽和行为意图的重要提示。这项研究的发现可以促进交互性研究和模型的发展以及更好的网站设计。
