I'm fully aware "Virtual Youtuber" doesn't mean Virtual Reality, nonetheless I think the two spaces benefit each other and are definitely connected and correlated.

As such, what do you think will be Brain Control Interfaces' and VR's impact on v-tubing? With eye tracking and a brain control interface it seems a natural addition to current v-tubing hardware. I imagine you could program some interesting things with BCI technology.
For example, you could have your expression change based on emotion/visual information. Currently available consumer technology can do this to a limited extent. Since these are the early days you'd probably have to map it and it would require focus, but still quite something to consider.
