Interactive Reading Using Low Cost Brain Computer Interfaces

Abstract

"Although Brain computer interface (BCI) devices are beginning to aim at the consumer level, their cognitive usability is still limited, especially for a physically-disabled person. To improve usability of BCI interfaced devices, we employed the Emotiv Epoc, a low-priced electroencephalography (EEG) headset, to design and build a proof-of-concept document reader system that allows users to navigate the document without the need of physical actions. Our prototype has been implemented and evaluated with 12 participants who were trained to navigate documents using brain signals acquired by Emotive EEG. In addition to testing cognitive actions of participants, we also proposed an automata theory based benchmark to model the participants' behaviours. Furthermore, our framework is also able to identify every software bottleneck and to provide future ways for improvement."
