分析视线跟踪数据
我有一张图像，向对其内容具有不同领域知识的人群展示。然后我记录了他们观看图像的注视数据。
我现在有点想比较两组的结果 - 所以我需要知道的是，两组之间的采样数据的位置是否存在相关性。
我有原始图像以及固定坐标。您知道如何开始分析数据吗？
更多的是关于想法或计划，所以你不必在这方面太专业。
谢谢
I have an image which was shown to groups of people with different domain knowledge of its content. I than recorded gaze fixation data of them watching the image.
I now kind of want to compare the results of the two groups - so what I need to know is, if there is a correlation of the positions of the sampling data between the two groups or not.
I have the original image as well as the fixation coords. Do you have any good idea how to start analyzing the data?
It's more about the idea or the plan so you don't have to be too technical on that one.
Thanks

简单的想法：以“热图”之类的方式渲染原始图像上的所有坐标，每组一个图像。然后，您可以直观地比较图像的相关性，并且您的论文中会有一些漂亮的图形。
有一个类似于二维相关系数的东西。使用 R 或 Matlab 您可以对相关性进行数字运算。
Matlab 有一个用于此目的的函数：
二维相关函数：corr2
Simple idea: render all the coordinates on the original image in a 'heat map' like way, one image for each group. You can then visually compare the images for correlation, and you have some nice graphics for in your paper.
There is something like the two-dimensional correlation coefficient. With software like R or Matlab you can do the number crunching for the correlation.
Matlab has a function for this:
Two Dimensional Correlation Function: corr2
在视线追踪中，最有趣的数据存在于两个领域。
生成的热图集（可能是第二点的热图的动画）应该为您提供一些进一步分析的指导。
In gaze tracking, the most interesting data lies in two areas.
The resulting set of heat-maps, perhaps animated for the ones from the second point, should give you some pointers for further analysis.
