For VR: PiEEG XR measures brain activity in real time

The PiEEG XR is a new interface for XR and therefore also for applications such as VR. It is essentially an input device that functions as an EEG system. The abbreviation stands for electroencephalography and ultimately refers to the measurement of brain activity. It should be noted right away that the system will be funded through a Kickstarter campaign and is not necessarily a typical consumer product. Instead, it is also aimed at makers and researchers. APIs and SDKs are intended to allow use in a wide range of contexts and without strict manufacturer specifications. The project is also backed by Ildar Rakhmatulin, a recognized expert in this field who has already attempted to bring other projects to market.

At the hardware level, the PiEEG XR is essentially a replacement face cushion. Electrodes are built into it, which are then responsible for measuring brain activity. Data processing is handled by ironbci, which can record 250 data points per second. This should also enable high temporal resolution. Communication takes place via Bluetooth, which should be very practical in the era of fully wireless VR headsets such as the Pico 4 Ultra that we have already tested. The system will be available as the PiEEG XR Mask, as a research kit with ironbci and as an all-in-one version for consumers. Native VRChat compatibility is advertised.
