This past week, I prepared and presented the proposal presentation. I acquired the Emotiv Insight headset from the ECE inventory and did some initial testing/investigation. I read research papers which studied attention using EEG data to get a better understanding of how to process the raw EEG data and what kinds of models people have had success working with in the past. I set up the headset on myself and got it connected to my laptop via bluetooth. At this point, I encountered some issues trying to get a high fidelity sensor connection to my head. I messed around with adjusting the headset on my head according to the specifications and applying saline solution to the sensor tips. Eventually, I was able to get the sensor contact quality to be steady in the 60-70% range. I also realized that we will need an EmotivPRO subscription to export any of the raw EEG data off the headset, so I filled out the order form and reached out to Quinn about how to go about getting the license. My progress is on schedule. In the next week, I need to chat with Jean to get feedback as to how to improve our sensor contact quality or at least understand what range is acceptable for signal processing. I need to secure the EmotivPRO subscription so we can port the raw EEG data from the headset. At this point, I will work with Arnav to develop a training data labeling platform that Professor Dueck will use to label her students’ raw EEG data as focused, distracted, or neutral. Finally, with the EmotivPRO subscription, I can also start setting up some simple signal processing processes to preprocess and interpret the EEG data from the headset to detect focus levels.
