System overview

A headset, an application and a cloud classifier.

The Nurochek-Pro System evokes and records steady-state visual evoked potentials (SSVEP) via electroencephalography. It records across three channels of the 10–20 system — O1, O2 and Oz — using clip-in soft sensors as a non-invasive conduit to the scalp. The headset connects to a computer over an isolated USB-A link; data is processed in the cloud by a proprietary classification algorithm. An internet connection is required to sign in and process readings.

Headset
