Feasibility study of performance evaluation using national instruments based neurophysiology device (NIROD)

摘要

This project takes the challenge to utilize the single probe methodology to evaluate the SSVEP response stimulated by various mental tasks. Reading is the main activity of interest for the research as it wholly exploits the visual sense as well as requiring full mental concentration from the subject. Most of the applications in the market today use SSVEP for visually evoked menu and characters recognition, but to the best knowledge of the authors, no research has been carried out on the analysis of the SSVEP response through a head device with only a single contact point to correlate the reading speed or learning efficiency (through visual sense) by looking at the SSVEP waveform. In order to evaluate the learning efficiency using the SSVEP data, our hypothesis is the reading activities of the neuron response itself is a stream of self-visually evoked potential. Thus, it is possible to evaluate the learning efficiency by correlated to the SSVEP of the reader or learner brain wave. A simple model is proposed to correlate the reading activity to the EEG analysis.
