Focus Wearable

While taking a class in Wesleyan's Integrated Design, Engineering, and Applied Science (IDEAS) department, I designed this system as my final project. Originally intended to utilize a BLE connection to minimize wearable dimensions, this is a two-part device. The first part is a wristband containing an Arduino microcontroller, a haptic vibration motor, and a battery (the switches you see are for debugging purposes). The second component is a NeuroSky EEG headset configured to compute an alpha to beta brain wave ratio. Together, the code I wrote would constantly receive the computed output ratio from the headset and interpret these values as a representation of "focus". Then, the worn wristband would communicate these values to the wearer when they would stray outside of a calibrated optimum, informing the wearer of their focus status. I found it very useful during long lectures!
