Over the course of the late summer and early fall I worked extensively on the OpenBCI Graphical User Interface (GUI). The first version of the application, as seen in [Image 2] below, was developed by Chip Audette, who is one of the biggest OpenBCI contributors and runs the amazing blog EEG Hacker. The GUI is developed in Processing, a Java-based creative coding framework.

I worked on:

• [Image 3] updating the design & user experience (w/ the help of Agustina Jacobi)
• [Image 4] adding a UI controller to manage the system state (initial hardware settings, startup, live data streaming mode, playback mode, synthetic data mode, etc.)
• [Image 5] adding a UI controller to manage OpenBCI board channels settings
• the startup protocol for establishing a connection between the OpenBCI GUI and the OpenBCI Board
• a collapsable window for adding and testing new features, called the “Developer Playground”
• a widget at the bottom of the application that gives feedback to the user about what the system is doing
