AttentivU: a Wearable Pair of EEG and EOG Glasses for Real-Time Physiological Processing

Recently several research projects have explored using physiological sensors such as electroencephalography (EEG) or electrooculography (EOG) electrodes to measure the engagement of a user in different contexts and augment learning activities. However, these systems still suffer from limitations such as an absence of a socially acceptable design, or use of impractical gel-based electrodes. We present AttentivU, a device using both EEG and EOG for real-time monitoring of physiological data. The device is designed as a socially acceptable pair of glasses and employs silver electrodes as an alternative to the commonly used silver/silver chloride (Ag/AgCI) "wet" electrodes. A detailed description of the hardware design and proof of concept prototype is provided, as well as a side by side comparison of conventional wet electrodes.
