Hi Grant,
Thank you! Got it working well. Got it working to draw on the canvas in the right places.
Now I have another very random issue. It was working fine and then all of a sudden the tracker stopped working. It enables me to calibrate the device and activate eye tracking for that purpose and then once calibration has finished it says “eye tracking not available” and in the Components area it says that the Tobii Controller Core is not available. Any suggestions as to why this happened and so randomly?
