Abstract:
A brain-computer interface (BCI) can arguably be considered the ultimate user interface, where humans operate a computer using thought alone. We have integrated the Anon-BCI into a highly immersive Cave-like system. In this paper we report a case study where three participants were able to control their avatar using only their thought. We have analyzed the participants’ subjective experience using an in-depth qualitative methodology. We also discuss some limitations of BCI in controlling a virtual environment, and interaction design decisions that needed to be made.
