Human-Computer Interaction Issues in Brain- Computer Interface and Virtual Reality

Recently, there has been increasing interest in using BCI in 3D virtual environments. There are several reasons for using a brain-computer interface in virtual reality (VR); some of these are the same reasons for using VR in general: rehearsal of scenarios that are too dangerous in the real world (e.g., controlling a wheelchair); prototyping devices (e.g., robotic hand); prototyping new control methods; studying the effects of "watching virtual body part actions" (e.g., applied for stroke rehabilitation); and increasing motivation and/or mental effort in BCI feedback experiments.
