摘    要:数字化交互界面中的信息呈现方式对操作员信息特征搜索的任务执行效率起着至关重要的作用.文中以信息特征及呈现方式作为变量,展开视觉搜索实验.首先提出搜索不同复杂程度的信息单元、不同形态特征对凝视/扫视及瞳孔幅度呈规律性变化等3个假设,并以核电安注系统为例进行实验设计;其次通过眼动实验数据记录的凝视/扫视时间及路径指标、瞳孔直径进行比较,并讨论信息复杂程度与瞳孔幅度变化、凝视时间与瞳孔幅度的一致性效应.实验结果表明,图标形态和信息呈现方式对视觉搜索均具有显著性影响,凝视/扫视时间及路径能够反映图标形态的复杂程度及信息呈现的难易程度;瞳孔变化幅度与凝视/扫视指标相同,也可作为视觉认知绩效的灵敏指标,单一图标-形态组B到信息块形态组A呈线性递增趋势,具有一致性效应.该结论揭示了信息特征搜索的影响因素,瞳孔幅度变化与凝视/扫视指标的一致性效应可作为信息呈现方式的重要指标应用于未来界面优化设计中.

关 键 词:信息特征  视觉搜索  凝视/扫视  瞳孔幅度  一致性效应

Abstract:Information presentation form of digital interactive interface plays a vital role in operators’task execution efficiency of information features search.This paper takes information features and presentation form as variables to conduct visual search experiments.Firstly,taking nuclear safety injection system as an example for experimental design,three hypotheses are proposed,that is,searching for information units with different levels of complexity,different shape features have regular changes in fixation/saccade and pupil size and so on.Secondly,the fixation/saccade time,path indicator and pupil diameter recorded in eye-movement experiment are compared and analyzed.Congruent effects on different levels of complexity of information,fixation time and pupil dilation are discussed.The experimental results show that both icon shape and information presentation form have significant influence on visual search.The fixation/saccade time and path can reflect the complexity of icon shape and the difficulty of information presentation.Pupil changing size and fixation/saccade indicators can be used as sensitive indicators of visual cognitive performance.From single icon-shape B to information block-shape A,there is a linear increasing trend with congruent effect.This conclusion reveals the influencing factors of information feature search.Congruent effects between pupil changing size and fixation/saccade indicators,important indicators of information presentation form,can be applied to future interface optimization design.
Keywords:information feature  visual searching  fixation/saccade  pupil dilation  congruent effect
