CytonRK: a custom head-mounted portable EEG recorder for classroom use¶

Description¶

The CytonRK is a bespoke head-mounted EEG device built by the lead author because no commercial device met classroom requirements. It uses an OPENBCI Cyton board with an ADS1299 8-channel converter, records at 250Hz to local micro-SD memory with a battery-backed real-time clock, and uses dry Silver Chloride comb electrodes on a 25mm elasticized harness designed for minimal invasiveness in hair.

Design Implications¶

Context¶

Requirements¶

Local memory recording was chosen because Bluetooth pairing of up to 26 devices in one classroom was impractical and school WiFi networks were infeasible

Constraints¶

The article notes temporal electrode placement was moved from just in front to just behind the ears after participant feedback about pressure irritation

Target Learners¶

high school students in naturalistic classroom settings

Learning Goals¶

recording EEG-based indicators of attention and working memory during real classroom assessments
