基于眼动实验的核酸检测仪人机界面优化研究

Optimization of Nucleic Acid Detector Interface Based on Eye Movement Experiment

为了优化核酸检测仪人机界面的信息显示质量,提升界面操作效率和准确性,采用问卷调查和启发式评估对仪器的操作系统进行整体评估,利用眼动实验开展阶段性任务测试,使用系统可用性量表进行定量分析,通过用户访谈进行定性分析。根据评估和分析结果优化系统界面后再次对其进行眼动实验并要求被试填写系统可用性量表。实验结果发现,优化后的界面操作效率和准确性均更高。因此,以眼动实验为核心,采用定量与定性分析结合的优化设计方法能提高医疗器械界面的认读效率并减少检测人员的视觉疲劳和错误操作。

To optimize the human-machine interface and information display of nmuceie acid dector and improve the efficiency and accuracy of the instrument interface operation,questionaire and heuristice assessment are used to evaluale the system as a whole,and then lask based tests are conducted on the original interface based on eye movement experiment.System usability scale is used for quantitative analysis,and user interview is conducted for qualitative analysis.The interface is optimized with the resuls from evaluation and anaysis,and eye movement experiment is performed on the optimized interface again,and the SUS is flled in by subjects.Theoperation efficiency and accuracy of the optimized interface have been improved.Therefore,taking eye movement experiment as the core,combining quantitative and qualitative analysis can improve the reading eficiency of medical device interface and reduce visual fatigue and misoperation of inspectons.
