CameraEEG: Synchronous Recording of Electroencephalogram and Video Data for Neuroergonomics Applications

Abstract

Lab-confined electroencephalogram experiments generally impel the subject’s mobility. Hence, we provide a wearable solution enabling human brain activity while monitoring during everyday activities, especially for neuroergonomics. This paper introduces CameraEEG, a new Android application that allows for synchronized smartphone acquisition of electroencephalogram (EEG) and camera data. Using a button on the app, the subject can record the witnessed audio-visual events of interest. Android SDK version 28 and mBrainTrain’s Smarting Mobi SDK were used to develop the app. The app can be used across all Android smartphones that have Android OS–Lollipop at least. In this paper, we used the app to record synchronized video and EEG data from four subjects during two tasks (namely, closed and open eyes), each under sitting conditions. We used the POz electrode data for analysis. There was a visible difference between the power spectrums of both the tasks, with the eyes-closed task reflecting an alpha band peak. Also, the obtained video and EEG data showed accurate synchronization. A download weblink for the .apk file along with a detailed help document for the developed app is provided for further testing.
