Testing time: To see whether the modified VR headset could accurately record brain activity, the researchers had four participants wear it while opening or closing their eyes on command. There is typically an increase in alpha waves in a person’s brain when their eyes are closed, and the researchers could see this increase in the EEG data recorded by their headset.
They also had the participants wear the headset while playing a custom game designed to trigger a type of brain activity that occurs when a person is preparing for an event. As hoped, the researchers were able to see this activity in the recorded EEG data, too.
Looking ahead: The UT Austin team has started filing the paperwork to patent their tech and say they’d be open to working with VR companies to incorporate it into their systems. They don’t say what it costs to make the soft electrodes, so it’s not clear exactly how much consumers or professionals should expect to pay for a modified VR headset.
