Brain-Computer Interfaces (BCIs) use the power of thoughts. They detect brain
activity to control external devices such as neuro-prostheses or personal computers.
The goal of this study was to explore the experiences of healthy persons
using BCIs in various applications. Based on maximum variation sampling, 24
qualitative interviews were conducted with healthy BCI users, such as neuro-gamers,
pilots, users of consumer BCIs, as well as BCI developers and researchers. Our findings indicate that human-machine interaction is influenced by BCIs
in a novel and unique way. The success of BCI use was highly linked to motivation
and duration of training. Discomfort was mainly associated with the time-consuming
procedure of electroencephalography (EEG). Moreover, cognitive
exhaustion by BCI use was reported. Most participants expressed being puzzled
and fascinated by BCIs, showing a high level of ambivalence regarding BCI
technology.
