The device, which includes built-in electroencephalography (EEG) sensors, is of course targeting developers and researchers hoping to integrate EEG data into XR applications, although it\u2019s also slated to arrive with native VRChat integration, letting users \u201ccontrol [avatars] directly from your brain and facial expressions,\u201d the company says.<\/p>\n<\/p>\n
Notably, EEG sensors measure electrical activity generated by the brain. However, consumer EEG systems generally don\u2019t \u201cdecode\u201d specific thoughts. Instead, they can detect broad signals associated with states such as attention, relaxation, or cognitive workload, which can then be mapped to software actions.<\/p>\n
That said, the company maintains its sensor-studded facial interface for Quest will enable more expressive avatars and additional hands-free input methods, which can be translated into various effects, modifying environments, or altering avatar animations based on attention-related signals using its \u2018Focus-to-Action\u2019 API. <\/p>\n

And like its other BCI hardware, the company says PiEEG XR is set to be fully open-source, providing access to software tools and raw data streams for developers, educators, and researchers. <\/p>\n
\u201cWhether you are a developer looking to build \u2018thought-controlled\u2019 horror games, or a researcher studying emotional responses in VR, the VR-Link provides the raw data and tools you need to innovate,\u201d PiEEG says.<\/p>\n
The EEG facial interface itself is powered by the company\u2019s IronBCI platform<\/a>, which includes 24-bit resolution, 250 samples per second acquisition rate, Bluetooth Low Energy 5 (BLE 5) connectivity, and low-noise signal acquisition.<\/p>\n
