摘要： 形状特征是影响人机交互界面视觉工效的关键因素，为使人机交互界面能更好地
适应用户的生理及心理特性、提升用户体验，需要建构一种人机交互界面中形状特征的视觉显
著度计算模型。在分析形状特征对视觉显著度影响程度的基础上，针对人机交互界面中的典型
形状，利用内接正方形将形状分割为多个部分，使用相关三角形对形状部分的视觉显著度进行
计算，取其中最大值作为形状的视觉显著度，实现形状视觉显著度的量化分析与计算，并通过
眼动追踪实验验证该方法的有效性。

Abstract: Shape feature is an important element of visual ergonomics of human-machine interface. In
order to improve the user experience and increase operation efficiency, a visual saliency calculation
model for shape features of human-machine interface isproposed. The influence of shape features to
visual saliency is analysed and several specific shapes are obtained which are used in
huaman-machine interface frequently at first. The inscribed square is used to segment the shapes and
some specific parts are got consequently. The triangle is related to the parts to calculate the parts’
visual saliency. The maximal value of parts’ visual saliency is taken as the visual saliency of the shape.
An eye tracking experiment verifies the effectiveness of the proposed visual saliency calculation
model.
