Description of a Wearable Electroencephalography + Functional Near-Infrared Spectroscopy (EEG+FNIRS) for In-Situ Experiments on Design Cognition

Abstract

We developed a wearable experimental sensor setup featuring multimodal EEG+fNIRS neuroimaging data capture applicable for in situ experiments at a lower financial threshold. Consistent application of a good protocol and procedure for sensor application and signal quality control is crucial for researchers to obtain valid data. This paper provides an exhaustive description of the sensor setup, the data synchronization process, procedure for sensor application, and signal quality control. Potential design cognition experiments with the proposed EEG+fNIRS are also described. In summary, the setup is mobile and provides multimodal neuroimaging data of high quality. We encourage the design community to take advantage of the setup and adapt it to new experimental setups in situ.
