Welcome to the Eyetracking Studio wiki.
##Datastructure
Images and the respective gazedata files are stored in the data folder. Gazedata files need to be in csv format, image files in png- or jpg format.
On execution of the main python script temporary files are created in the temp folder. Its content in json format is loaded by the web browser if requested.
Further code for the computation of the various visualizations is stored in the utilities folder.
###Naming conventions
To maintain mapping of images and gazedata, the csv files must be named like the related image, followed by an underscore and a number, e.g. exampleimage.jpg and exampleimage_01.csv.
###Gazedata file The gazedata is contained in csv files. The current status requires the file to contain some gaze information:
- Fixation index, an enumeration of the fixations of the participant.
- Fixation duration, the duration of the fixations.
- X- and Y-coordinate of the fixations on the test image.
- Fixation time, the corresponding timestamp of each fixation.
###Visualizations The recorded gazedata can be displayed in multiple ways:
###Animations Each visualization can also be displayed as an animation. Based on the recorded timestamp of the fixations in the gazedata file the animation can be played from start of the recoding until its end. Furthermore, a slider element enables the user to define a snippet of the record. Via a play- and pause-button it is possible to control the animation. Alike the visualizations, all animations are selectable for either one or multiple subjects.
