Inner Light
Inner Light is a meditative VR experience that provides audio-visual cues based on a player's brain activity (EEG) to induce a relaxed but focused mental state. It offers a unique conceptualization of the body-mind complex, asking questions about our mind/brain connection's (depicted by EEG waves) influence on our body, as well as who we are beyond it. Through this experience, I invite participants to embody their own mental frequencies and, finally, discover themselves in an out-of-body experience.
This project is part of my Masters Thesis that explored the therapeutic uses of VR and biosensing technologies like EEG, EMG, breath, etc.
Setup: Hardware + Software
- Emotiv Insight (hardware) is an EEG headset with 5 channels (AF3, AF4, T7, T8, Pz) and it transmits the raw signal data wirelessly through bluetooth to the computer.
- Emotiv Launcher (software) connects with the EEG headset and streams data over the cloud for processing/decoding using JSON and websockets to send/receive data.
- Cortex API for Unity (software) plugs into Unity and communicates with the Emotiv Launcher to receive processed data from the cloud. This data can then be utilized within the game engine to control parameters.
- Oculus Rift / HTC Vive (hardware) as PC VR setup, currently running on a MSI laptop. My input system (XRTK) within Unity is agnostic to hardware.
- VR application (game) is the prototype itself in which all the components come together audio-visually. It deals with the context and experiential aspect. The design decisions are based on my research and artistic vision.
