【摘要】：随着复杂信息系统在军事领域和民用领域的不断发展和广泛应用,人们对复杂信息系统显示界面的设计有了更高层面的要求。通过可用性评估指导复杂信息系统界面设计改良,降低系统复杂性带给用户的工作认知负荷,提高用户绩效成为亟待解决的问题。本文研究了现有的可用性评估方法,分析了复杂信息系统的界面复杂性和认知复杂性。确定了界面复杂度模型和基于复杂信息界面的可用性评估指标体系,并设计和实现了可用性评估资源库。主要工作有以下几个方面:1、通过专家访谈和用户调研确定影响界面复杂性的主要特征,用层次分析法构建了评估系统复杂度的模型,并确定了模型中各个因素的权重值。2、基于复杂度模型提炼出十余个可用性指标,丰富并完善了各个指标的内涵,并制定适宜的评估方法,最终构建出复杂信息系统可用性指标体系。3、选用一组可用性指标对复杂信息系统的显控布局方式进行试验评估,基于E-prime行为测试系统、Tobii眼动仪和NASA-TLX量表,对用户的反应时、正确率、工作负荷等指标进行评估,最终从四种设计方案中选出最佳方案,并基于评估结论对设计方案进一步完善。4、设计并开发了可用性评估资源库,根据实际评估工作的使用场景和用户需求,确立资源库软件信息架构、页面布局与交互逻辑,进一步提高研究成果的应用价值。
[Abstract]:With the continuous development and wide application of complex information systems in military and civil fields, the design of display interfaces for complex information systems has higher requirements. It is an urgent problem to improve the interface design of complex information system through usability evaluation to reduce the workload brought by the complexity of the system and to improve the user's performance. In this paper, the existing usability evaluation methods are studied, and the interface complexity and cognitive complexity of complex information systems are analyzed. The interface complexity model and the usability evaluation index system based on the complex information interface are determined, and the usability evaluation resource base is designed and implemented. The main work includes the following aspects: 1. Through expert interviews and user research to determine the main characteristics of the impact of interface complexity, using the Analytic hierarchy process to build a model to evaluate the complexity of the system. The weight value of each factor in the model is determined. Based on the complexity model, more than ten usability indexes are extracted, which enriches and perfects the connotation of each index, and formulates an appropriate evaluation method. Finally, the usability index system of complex information system is constructed. A set of usability indexes are selected to test and evaluate the display and control layout of complex information system. Based on the E-prime behavior test system, Tobii eye movement meter and NASA-TLX scale, the response to users is analyzed. The correct rate, workload and other indicators are evaluated, and the best scheme is selected from the four design schemes. Based on the evaluation conclusion, the design scheme is further improved. Finally, the usability evaluation resource bank is designed and developed. According to the usage scenarios and user requirements of the actual evaluation work, the information architecture, page layout and interactive logic of the resource library software are established to further improve the application value of the research results.
