Designs for low-cost air monitors and associated performance data appear in many peer-reviewed articles; however, few manuscripts provide feedback from end user's experiences or comprehensive evaluation. The present study addresses the usability of the wireless outdoor individual exposure indicator system from the viewpoint of the Malaysian Traffic Police (end users). This study is one of the first to chronicle end user experiences for low-cost pollution sensing.
The evaluation involved 12 target end users to assess the usability of a prototype for Malaysian Traffic Police to manage their exposure to outdoor air pollution. The test evaluation includes a pre-test, post-task and post-test questionnaire (Post-Study System Usability Questionnaire). The main components in this Post-Study System Usability Questionnaire are Overall satisfaction, System Usefulness, Information Quality and Interface Quality.
The results of the Post-Study System Usability Questionnaire indicated the mean score of the Overall satisfaction item (2.33), System Usefulness (2.25), Information Quality (2.36) and Interface Quality (2.17) on a scale of 1-10. Prototype users were satisfied with the system because the score is close to 1 on the Post-Study System Usability Questionnaire.
A user-friendly wireless outdoor individual exposure indicator system is now available for Malaysian Traffic Police. Users have stated that they are happy to use the system at work. However, in addition to more technological advances, practical implementation requires evidence supporting its efficacy, viability and effectiveness.
许多同行评审文章中都出现了低成本空气监测器的设计及相关性能数据；然而，很少有手稿提供终端用户体验的反馈或全面评估。本研究从马来西亚交警（终端用户）的角度探讨了无线户外个人暴露指标系统的可用性。本研究是最早记录低成本污染传感终端用户体验的研究之一。
评估涉及12名目标终端用户，以评估一款供马来西亚交警管理其户外空气污染暴露的原型产品的可用性。测试评估包括预测试、任务后和测试后问卷调查（研究后系统可用性问卷）。这份研究后系统可用性问卷的主要组成部分包括总体满意度、系统有用性、信息质量和界面质量。
研究后系统可用性问卷的结果显示，总体满意度项目（2.33）、系统有用性（2.25）、信息质量（2.36）和界面质量（2.17）的平均得分在1至10分的量表上。原型用户对该系统感到满意，因为在研究后系统可用性问卷上的得分接近1分。
现在有一款用户友好型无线户外个人暴露指标系统可供马来西亚交警使用。用户表示他们很乐意在工作中使用该系统。然而，除了更多的技术进步外，实际应用还需要有证据支持其有效性、可行性和效能。
