Virtual simulation devices help to create a virtual world for the user. With the help of virtual simulation web stores can be converted into virtual stores and users can experience almost real shopping experience of picking objects and keeping them in their carts, without actually coming to the physical store. The current field of interest in virtual simulation technology is virtual input devices such as Brain Computer Interface or BCI. With the help of BCI the virtual experience can be made more close to reality and more user friendly. The effort required to navigate the virtual environment, would be much less with BCI. As per IT researchers BCI is the future of virtual simulation technology.
