PiEEG Server · MIT

Server Experiences

Open-source gallery shipped with PiEEG Server. Source on GitHub.

PiEEG Cloud

Cloud Experiences

Additional experiences on PiEEG Cloud: decoders, trainers, XR, and labs that are not in the MIT server gallery. Open any card to launch it.

Mushroom Body Decoder

Live EEG band powers drive a fruit-fly mushroom-body circuit. Sparse Kenyon-cell code, trained KC-to-MBON readout, held-out balanced accuracy.

BCI / Connectome

octoCaptcha

Cognitive liveness check: a random blink-count nonce after a GO cue, verified from Fp1/Fp2 EOG morphology and timing.

EOG / Liveness

octoAuth

16-channel neck EMG identity challenge: random isometric actions plus a person-specific spatial signature.

BCI / Biometric

Silent Speech Interface

Closed-vocabulary subvocal sEMG decoder. Enrol a command set, then silently mouth words onto the screen.

BCI / sEMG

Signal Lab

EEG DSP as a course: time domain, cleaning, and frequency domain. Live sandbox on your stream, then a quiz.

Learn / Game

Room Buddy (AR)

Place a buddy in your room. It waves, hops on focus, and flinches on blinks from live EEG.

AR

PiEEG Virtual Lab

Walk a photoreal lab and sit at a workstation running the live PiEEG dashboard. Desktop or VR.

Lab / VR

Neural Wave Space

Immersive 3D EEG visualization: waves curve around you in a starfield. VR with hand tracking.

VR / 3D

Neural Flight

First-person flight over a procedural world. Focus is lift; lose it and gravity takes over.

VR / AR

VRChat OSC · Brain Regions

Per-region EEG band powers to avatar parameters, with montage presets and a sync-budget guide.

VRChatLocal server

Mind Reader

P300 number guess: think 1-9, count the flashes; shrinkage-LDA plus Bayesian accumulation reads the ERP.

BCI / ML

Avatar Neurofeedback Studio

Map electrode x band to facial expressions on a VRM avatar. Contrastive rest vs active ranking picks the strongest cue.

BCI / Avatar

Avatar Neurofeedback Studio v2

Second-generation avatar trainer with the same channel-band mapping studio as v1.

BCI / Avatar

Premeditatio Malorum

Paired 360 scenes for Stoic drills. Score is how fast a beta spike decays back to your eyes-closed baseline.

XR / Stoic

The Glitching Reality

Passthrough plus a shader: frontal alpha asymmetry keeps the room intact; load tears it. A breath restores it.

MR / Shader

Face Trainer

Placement-agnostic facial EMG: per-expression L2 + group-lasso detectors, leave-one-rep-out balanced accuracy.

BCI / Face

Face Trainer v2

Same fEMG pipeline with a 3-2-1 recording rhythm: more labelled samples per rep, independent storage from v1.

BCI / Face

Hand Trainer

Palm sEMG grip decoder for Aura: fist, open, pinch, point, thumb-up. IMU owns wrist orientation.

BCI / sEMGAura

Aura IMU Lab

6-axis IMU lab: still-hold calibration, gravity-compensated accel, ZUPT, a 3D hand that translates. Position drifts.

IMU / DebugAura

BioPose Recorder

Recording bench: camera body stick plus live bio traces. Review, mark, export. Pose is a vision estimate. Pixels are not stored.

Lab / Pose

Aura Dataset Lab

Guided EMG + IMU records with rest/hold labels. Optional optical autolabel. Export JSON or 50 Hz synced CSV.

sEMG / DatasetAura

Hand of God

Hang-ball punch game. Optional Aura fist training. Score only when the ball is high and the referee looks away.

BCI / GameAura

Aura Handwriting

Palm sEMG gates pen-down; wrist yaw/pitch rates draw a unistroke. 1-NN DTW on enrolled templates. EMG does not identify the glyph.

IMU / sEMGAura

Penalty Shooters

Blink-controlled penalty kicks. Trainless adaptive detector on frontal peak-to-peak. Press start and play.

BCI / Game

Neural Maze Lock

EOG gaze steers a maze. Focus, calm, and blink gates confirm intent. Tracks false triggers and completion time.

BCI / Game

Orb Control

Focus grabs an orb, EOG gaze moves it, calm steadies it, frontal artifacts destabilize it, a blink releases charge.

BCI / EOG
