Not getting fixations

Jul 25, 2012 at 9:01 AM

Can anyone tell what went wrong I am not getting the fixations. I have shown every image for 5 secs to 5 different persons. I am not getting any kind of fixations. Only in the replay module it shows how gaze of every person travelled through every image. I need fixations for analysis. Here, I am providing a link to compressed file of the project folder.

Hi there, the files are removed from dropbox in the meantime, please send them to adrian@ogama.net. In the meantime the reason can be the following:
A) Your raw data is to scattered, so that the algorithm does not track the fixation because the samples where thought not to be at the same location. The algorithm is a moving window, so try to widen the window, and it may help. (-> see the experiment settings dialog)
B) Your raw data is to low frequent, so that the algorithm does not have enough samples at the same location to detect this location as a fixation. (-> see experiment settings for changing the number of samples that are needed to build a fixation)
Regards, Adrian
