Foci of Fidelity
A foci of fidelity is something encountered in simulations, as the point or points where the simulation mimics an outside reality as closely as possible. Around the foci, the environment is modelled as close as possible to the interactions that would be possible. Away from the loci, increasing levels of abstraction are employed ? smoke and mirrors to give the impression of continuous simulation, when in reality there is only a very small section present at the time.

MoCap - Motion Capture - for all its impressive abilities, has definite limitations in terms of sensory fidelity, the expense and bulk of the rig. Gesture control is cheap and captures every little movement, but easily overwhelmed. Is a hybrid system possible?
Diffusion spectrum imaging is a new technique at time of writing, which allows magnetic resonance brain imaging, at a much higher level of fidelity than fMRI permits.
Electrocorticography or ECoG is a method of neural interface in which an electrode array, quite like a fine mesh, is draped over the upper surface of the brain directly, under the skull. A section of the skull is removed to allow the array to be fed in, then replaced. The result is near-identical to a high fidelity EEG that is under the skull and thus away from its pattern dampening properties.
