[open] Help with eye-tracking programming...
I am working on an eye-tracking project using the EyeTribe tracker and have started editing the "Pygaze Eyetracking Template" included with the Pygaze plugin for Opensesame. What I would like to do for this project is be able to record the gaze coordinates from the subject while they trace an object in the sketchpad (i.e. A triangle in this situation) and compare these coordinates to the actual coordinates of the lines making up the triangle. The purpose behind this is to be able to measure the saccades that the subject is experiencing while tracing this object and determine if they are suffering from a neurological issue. I have VERY little knowledge about programming and therefore am having several problems trying to code this experiment. The problems I am having currently are:
- Adding an "instruction" that asks the subject to "trace the object shown on the screen"
- Somehow determine the actual coordinates of the triangle I have drawn (all coordinates lying on the line)
- Make it so that you can press a key to end the experiment once the subject is finished tracing
These are the problems I have come across so far. If you have any other suggestions or advice that will make this experiment better, feel free to share! Thank you so much for your help!
