This may be an exercise in multi-modal embodied cognition: the virtual/phantom limb is perceived visually in virtual space. Can one say it is “represented?” It stands for an “actual” limb that doesn’t exit., and the rest of the body is unrepresented.
One wonders what would happen if the virtual limb were connected to the amputated region’s nerve endings, and if the “virtual space” could also become a 3d representation of a 2d interface. Would that limb develop interface fluencies of its own? Would it be experienced as being in the same or a different space?
