Mindsoul XR

Mindsoul XR is a brain-computer interface (BCI) assistive application for Android XR spatial computing devices. After wearing an XR headset and a wireless EEG headband, your focus, relaxation level, and raw EEG waveforms are presented in real-time in a 3D visualization within an immersive space, allowing for natural, memory-based conversations with an AI assistant.

We aim to bring "understanding the brain" from the laboratory into everyday spatial computing scenarios: researchers can more efficiently complete data annotation and model iteration, clinical and rehabilitation teams can conduct training and follow-up in an immersive environment, and ordinary users can establish more stable attention and emotion management habits through real-time feedback on focus and relaxation.

【Main Functions】

· EEG Device Connectivity Connects to BrainLink Pro/Lite/Mind Link and other EEG headbands via Bluetooth, automatically scanning and pairing, with the connection status visualized in the XR space.

* Real-time EEG Visualization: Multi-channel EEG waveforms, attention and relaxation indicators are rendered in real-time in 3D space, with switchable immersive backgrounds to help you intuitively perceive changes in your brain state.

* Semantic and Motor Imagery Acquisition: Built-in annotation tasks include word-by-word sentence reading and left/right hand motor imagery. Combined with synchronized EEG acquisition, this helps train AI models to understand the meaning behind EEG signals, making it an efficient tool for scientific research and data annotation.

* Spatial Gesture Keyboard: A 3D floating keyboard based on hand tracking allows for text input in space without a physical keyboard. It supports gesture calibration to adapt to different user habits.

* Imagination Gallery: Manage and browse image content generated or associated with EEG signals, building a traceable "imagination index."

* AI Memory Conversation: Engage in natural conversations with the AI ​​assistant in XR space. The AI ​​persistently remembers your past interactions, maintaining continuous context across multiple conversations.



** • Multiple Environment Switching
Offers a variety of immersive 3D scene backgrounds, allowing you to switch atmospheres according to different tasks such as training, focus, or meditation.
