Software utilizing interaction designs that require extensive dragging or clicking of icons may increase users' risks for upper extremity cumulative trauma disorders. The purpose of this research is to develop a Self-report Ergonomic Assessment Tool (SEAT) for assessing the risks of software interaction designs and facilitate mitigation of those risks. A 28-item self-report measure was developed by combining and modifying items from existing industrial ergonomic tools. Data were collected from 166 participants after they completed four different tasks that varied by method of input (touch or keyboard and mouse) and type of task (selecting or typing). Principal component analysis found distinct factors associated with stress (i.e., demands) and strain (i.e., response). Repeated measures analyses of variance showed that participants could discriminate the different strain induced by the input methods and tasks. However, participants' ability to discriminate between the stressors associated with that strain was mixed. Further validation of the SEAT is necessary but these results indicate that the SEAT may be a viable method of assessing ergonomics risks presented by software design.
使用需要大量拖动或点击图标的交互设计的软件可能会增加用户患上肢累积性创伤疾病的风险。本研究的目的是开发一种自我报告式人体工程学评估工具（SEAT），用于评估软件交互设计的风险，并促进这些风险的缓解。通过合并和修改现有工业人体工程学工具中的项目，开发了一种包含28个条目的自我报告测量方法。在166名参与者完成四种不同任务后收集了数据，这些任务因输入方法（触摸或键盘和鼠标）和任务类型（选择或打字）而异。主成分分析发现了与压力（即需求）和应变（即反应）相关的不同因素。重复测量方差分析表明，参与者能够区分由输入方法和任务引起的不同应变。然而，参与者区分与该应变相关的压力源的能力参差不齐。虽然有必要对SEAT进行进一步验证，但这些结果表明，SEAT可能是评估软件设计所带来的人体工程学风险的一种可行方法。
