晃动环境下信息元素设计对视觉搜索的影响

Influences of information element design on visual search in vibration environments

随着舰船先进信息系统的发展,越来越多有关信息界面的人机交互任务需要在晃动状态下进行.针对3种晃动状态,进行低(8个)、中(28个)、高(48个) 3种元素密度,大(6. 98 mm)、中(5. 24 mm)、小(3. 49 mm) 3种元素大小的人机交互界面设计,通过对重复测量实验结果采用方差分析和卡方检验的方法,研究不同晃动状态下视觉搜索界面元素设计方式对视觉搜索绩效和用户偏好的影响.结果表明,元素大小和密度对视觉搜索效率和用户偏好有显著影响,但晃动状态对视觉搜索绩效并无显著影响.用户更偏好于中低密度和中大尺寸的元素设计.实验结果可供船舰信息界面的交互设计参考.

With the development of advanced shipboard information systems, an increasing number of human-computer interaction tasks related to information interface are required to be performed in vibration state. For three vibration states, the human-computer interaction interface design with three element densities of low (8), medium (28 ), high (48) and three element sizes of large (6.98 mm), medium (5.24 mm) and small (3.49 mm) is carried out. By using analysis of variance and chi-square on the experimental results of repeated measurement, the effects of element design on visual search performance and user preference in different vibration states are studied. The results show that element size and density have significant effects on visual performance and user preference, while the vibration envi ronment has no effect on visual search performance. Users prefer medium-low density and medium-large size element design. The experimental results provide a reference for the interaction design of shipboard information interface.
