Literature shows incidence of musculoskeletal disorders in bricklaying workers as well as the relevance of good designed hand-held tools in musculoskeletal disorders prevention. In this framework, it can be supposed that providing usable hand-held tools and material in construction worksites will help to improve bricklayers' working conditions. Here a study is presented aimed at framing a methodology for usability assessment of bricklayers handled objects, in order to provide employers with practical indicators for choosing tools and materials best fitting workers needs, under the effectiveness, efficiency and satisfaction perspective. On the basis of a task analysis, usability requirements for bricklaying hand-held tools and materials have been detailed and related, quantitative and qualitative, technical specifications have been elicited. Theoretical framework and usability assessment methodology are presented and, finally, findings from a field application are discussed.
文献表明砌砖工人肌肉骨骼疾病的发病率，以及设计良好的手持工具在预防肌肉骨骼疾病方面的相关性。在此框架下，可以推测在建筑工地上提供可用的手持工具和材料将有助于改善砌砖工人的工作条件。本文提出了一项研究，旨在构建一种用于评估砌砖工人操作对象可用性的方法，以便从有效性、效率和满意度的角度为雇主提供实用指标，用于选择最符合工人需求的工具和材料。在任务分析的基础上，详细阐述了砌砖手持工具和材料的可用性要求，并得出了相关的定量和定性技术规范。介绍了理论框架和可用性评估方法，最后讨论了现场应用的结果。
