ABSTRACT
This paper describes an exploratory study examining the feasibility of using Brain-Computer Interface (BCI) and gestural technologies to support individuals who are blind during the authentication process. Four legally-blind participants were asked to don the Emotiv Epoc headset, and authenticate entry using gestural cues, emotional cues and mental commands. Findings highlighted that while BCI and gestural technologies may be slower and less accurate to use compared to four digit PINs, levels of perceived security were higher, as some of these cues were thought to be more difficult for third parties to replicate. A trade-off between perceived security and usability was evident.
