NeuroReach: prototype-to-pilot boundary

rehab game work + support groups + a few test users over the summer. Clinic access still slow; keep track of what was actually running in each session, live EEG vs mock vs camera stub recorded summer activity: adapting the EEG-control project...

NeuroReach: feasibility measures and data model

first things to track: setup time, comfort, instructions making sense, abandoned sessions. Save difficulty + normalization alongside scores or future me gets a graph of ??? First evaluation goal: setup feasibility, instruction comprehension,...

NeuroReach: v1-to-v2 architecture map

Unity → React/TS for the patient side, Electron console + Python signal engine. Keeping the folder map here; check the pending list before assuming a whole path is hooked up architecture revision in the engineering specification: replace the...

NeuroReach: ERD features and calibration contract

ERD formula + calibration timings here so I stop hunting around. near-zero baseline? check trial split BEFORE generating overlapping windows, sneaky leakage possibility Feature definitions recorded: ERD% = (Pbaseline - Ptask) / Pbaseline * 100 ;...

NeuroReach: score fusion, holds and wire payload

held score ≠ fresh score. Need artifact flag + null sub-scores, and don’t keep updating EMA/normalization while holding Specified score: IntentScore = w_eeg*EEG_Score + w_kin*Kinematic_Score - Penalty_Compensation , normalized to 0–100....

NeuroReach: pairing and local delivery contract

pairing codes: expiry, second browser, reconnect, sidecar dying. Need to try all the annoying paths, especially browser still connected while Python is gone lAN responsibilities: serve the React build over HTTPS, pair one browser to a live...

NeuroReach: game-state and validation references

same packets through pure model + rendered game, compare behavior. Log the difficulty staircase too; higher score could just be easier targets game references: docs/gardengrow.md and docs/reachcollect.md ; patient-web/src/garden|reach/ for...
