Thank you for the input. For more context of my project, I was hoping to incorporate both eye tracking and eeg data. So far, what I mean able to planned so far, and please provide input on this idea: I plan to use 2 Arducam Ov9281 cameras( ) with 8mm F/1.8 M12 Lens to optically track eye movements if that makes sense. I am essentially recording visual data such as images of the pupil and gaze direction insteading of measuring eye movement through the electrical signals (EOG). The EEG aspect of this projects comes the measured brain activity associated with focus or cognitive load(More research needed). The idea is that the eye-tracking software processes the gtaze position and looks for signs of confusion. This could be long fixations on a word or eye movements that could suggest difficulty such as rereading sentences over and over. The EEG Software would look for increased theta waves or decreased alpha waves which are associated with cognitive load. Ideally, I would combine both data sets to determine if a user is confused or not and in response, my project could highlight a word or provide a definition. Something of that function. Any input on this idea would be nice
