基于XML的数据可视化的一个重要目标是通过引导用户注意感兴趣的区域来检测数据集中的异常或管理复杂的搜索任务。先前的研究表明,用户的注意力与不同视角投影相遇的区域有关。我们描述了一种方法的透视变形的字形在一个虚拟场景中,而其余的场景是根据计算机图形相机的共同模型进行投影。结果是引导用户注意力的多视角图像。透视变形仅在用户聚焦于数据可视化的不相关区域时应用。一旦注视移向相关的目标,透视失真就逐渐消除。因此,我们在我们的原型实现中评估眼动跟踪数据。
An important goal of glyph based data visualization is to detect anomalies in data sets or to manage complex search tasks by guiding the users attention to regions of interest. Previous studies suggest that the user’s attention is tied to regions where different perspective projections meet. We describe a method for perspective distortion of glyphs within a virtual scene, while the rest of the scene is projected according to the common model of the computer graphics camera. The result is a multi-perspective image that directs the user’s attention. The perspective distortion is only applied if the user focuses on an irrelevant area of the data visualization. As soon as the gaze moves towards the relevant glyph, the perspective distortion is gradually removed. Therefore we evaluate eye tracking data in our prototypical implementation.
