几份事故报告已经确定移动的计算机终端（MCT）是警车事故的主要原因。之前的MCT可用性评价仅关注特定功能，可能无法推广到所有MCT模块。11名警察参与了这项研究，以评估MCT界面的可用性，并提供一套全面的指导方针，以改善其设计。可用性评估方法的组合，包括分层任务分析，大声思考，认知性能建模，启发式评估。调查结果显示，一些MCT任务，包括权证检查和事件查询是更复杂的相比，其他模块，不应该在驾驶时执行。发现了几个可用性问题，包括令人困惑的缩写、数据输入格式不一致、严重依赖工作记忆、错误信息不足以及不必要或冗余的信息。为提高警务人员使用流动电话测试系统的成效、效率和满意度，警方建议了一套实用指引。
Several crash reports have identified the mobile computer terminal (MCT) to be the main cause of police vehicle crashes. Prior MCT usability evaluations only focused on specific functionalities and might not be generalizable to all MCT modules. Eleven police officers participated in this study to assess the usability of an MCT interface and provide a comprehensive set of guidelines to improve its design. A combination of usability evaluation methods including hierarchical task analysis, think aloud, cognitive performance modeling, and heuristic evaluation were used. The findings revealed that some MCT tasks including warrant check and event query are more complex as compared to the other modules and should not be performed while driving. Several usability issues were identified including confusing abbreviations, inconsistencies in data entry format, heavy reliance on working memory, insufficient error messages, and unnecessary or redundant information. A set of usability guidelines was proposed to improve the effectiveness, efficiency and satisfaction of police officers in using the MCTs.
