Switchable Body Parts
Sometimes it is easier in rigid body animation, instead of trying to perform complex movements with many joints, and have the skin texture stretch realistically, to just switch out one body part, say a straight arm, with a bent arm model halfway through the act of bending it. The bent model has already had the textures repositioned in new places, and the models are seamlessly changed partway through an animation sequence. These are known as switchable body parts.

The brainstem is the part of the brain that descends just in front of the cerebellum. It drops down from the brain to meet and meld with the spinal cord rising from the body. The issue is, how do we go about hijacking the brainstem, to splice a virtual body, or artificial body parts onto it?
Why do prosthetic body parts have to limit themselves to copying the original organic components? When a large part of a person's body is synthetic, shouldn't they be free to express it, however they choose?
This July 2008 NewScientist article takes a look at the state of the art in prosthetics, and asks which of our body parts can be engineered today, and which will we have to make do with?
An informative article from late 2008 by The McGill Daily, examining the hurdles in using BMI (Brain Machine Interfaces) to control prosthetic body parts.
A story about the state of tech at the end of 2006. Neuroprosthetic devices had some concrete success stories in the past few years, and the stage was finally set for developing them, not to just monitor and interact with brain signals, but control external body parts as well.
From the fascinating title, this book might come across as something to do with the encroaching issues of how prosthetic body parts intermix with security concerns. This is not what the book is about. Instead, it is a weighty tome dealing with tracking how prosthetics affect the health of the general public.
Virtual Reality is just beginning to head down the full body sensation reproduction path. We are at the very early stages of being able to recreate parts of the physical form, entirely in the virtual. This is a concept which is likely to have very a profound effect upon how we deal with the world around us.
With the number of rubber body(part) studies that have been done, each showing that if it looks to be a body part, and feels like a body part, the brain accepts it as a body part, this research should also hold no surprises. We finally have direct proof of the concept that, when we utilize any tool, even for a scant few minutes, our brains integrate that tool into our self-body-image.
One of the greatest problems with prosthetic parts, is that artificial parts don't self-repair. This means that in the case of non-essential prosthetics such as bones, a patient usually outlives their prosthesis. They require the time, expense, and recuperation of additional new joint surgeries at least once per decade. It would be better to make the first prosthetic strong enough to outlive the patient.
Rubber hand, rubber body, rubber arm, rubber leg. Time and time again, studies have shown that even if a body part is completely fake, completely artificial, if enough of our senses tell us that it is us, then we believe it, consciously and subconsciously. This can easily be exploited by VR, such that what you perceive to be your body, IS your body, even when its really your avatar.
