A fully self-administered pipeline — participants wear, set up, record, and upload from home. Researchers get lab-quality data in the cloud. Higher data frequency per participant and quicker setup means researchers save money and do more research at a fraction of the cost.

AR Guided Self-setup
Walnot's portable kit eliminates the biggest bottleneck in longitudinal brain research: repeatable, scalable data collection in the real world.
With the Walnot wearable headband, participants can complete sessions at home, on their own schedule, without requiring a researcher onsite.
What used to be a scheduling problem becomes a data advantage.
Instead of struggling to get 3–4 lab visits, researchers can reliably collect:
After a short orientation session, the research participants take the kit home. open the app. AR guidance walks them through headband placement in under 2 minutes and verifies signal quality before any data collection begins. They complete their cognitive or any free-style tasks for 10-20 minutes per day. You see the session data appear in your HIPAA-compliant researcher dashboard.
No researcher required on-site. No scheduling bottleneck. Sessions happen on the participant's schedule — morning, evening, weekend.
Our published data in npj Digital Medicine (Rahimpour et al., 2025) shows that dense-sampled at-home wNIRS sessions achieve Reliability >0.9 — the accepted publication threshold — across all four cognitive tasks: N-Back (Working Memory), Flanker (Attention), Go/No-Go (Inhibitory Control), and Rest-State.
"Dense-sampled wearable fNIRS data improves the reliability and specificity of functional connectivity measures."
