EEG Data Collection Headset for AR/VR Research
Fall 2022
For my Senior Design capstone project, I worked in a team of three under mentors at Mitsubishi Electric Research Laboratory to design an EEG data collection headset that researchers could fit in unison with a variety of AR and VR headsets.
Problem Statement
The Mitsubishi Electric Research Lab (MERL) are interested in using an EEG headset device in unison with VR goggles, but the existing electrode cap was rigid, clunky, not adjustable, and potentially damaging to the VR goggles. Thus, the research team needed better mechanical hardware for sensing and collecting biosignals that can be flexibly integrated alongside VR headsets.
Project Goals and Design Requirements
We needed to design and fabricate a physical headset for OpenBCI comb EEG sensors that will collect data for a range of head sizes. The headset should fit with any type of AR/VR goggles in order to allow users to wear both headsets at once during data collection. The design should be replicable so that users of the OpenBCI system can recreate the design to use in their own research.
Design Overview
The final headset design consists of three bands 3D printed out of flexible TPU. The bands each house 2-4 electrodes that protrude from the underside to rest against the user’s head. The anchor headband and electrode bands can be tightened to any head size. The thin and flexible parts sit under almost any pair of VR goggles.
