Inverse Problem

The Inverse problem as related to neuroprosthetics and BMI, occurs with non-invasive interface brainwave interface methods. It arises as a triangulation problem, tracking back a registered signal, to the part and depth of brain it came from.

The real problem part comes in in that with the brain, an ?approximate? position is not good enough. The position must be as precise as possible. Between brain folds distorting the signal, the skull itself, soft tissue, hair and background noise, inverse tracking of brainwaves nets an almost infinite number of potential solutions.

Thus, a ?best-fit? is usually used, based on previous knowledge of that particular brain?s patterns, and a variety of advanced algorithms.

Below, we offer a selection of links from our resource databases which may match this term.

Large Image Display: Animatrix: Beyond: Fixing a Problem (2)
Continuing on from Large Image Display: Fixing a Problem, we see the same truck as evidenced in that frame, heading further into the city. This is a definite problem with every world that is heavily based on the recreation of natural laws. If you desire to do something that breaks those laws, you cannot. Not without breaking those laws, and as everything is interconnected, setting up a ripple effect that damages the simulation around the 'physical' area where you teleport.

Proof of Concept for “The 3D Printer Problem”
For SIGGRAPH 2013, one joint research team presented a proof of concept method to solve the 3D printer problem - the ability of any 3D printer to theoretically counterfeit any physical object small enough for it to print. They demonstrate a terahertz-radiation 'watermark' that can be 3D printed inside a genuine object, is easy to scan for, and very difficult to duplicate from the scan data.

PvP, Grief PK's, Death, Justice, Player Accountability
Why is PvP a problem anyhow? Are we looking at this from the wrong perspectice? Could PvP really be used to make the experience much more rewarding? Read this for the barest glimpse at the answers.

Keeping Control of Grief Players
A thorough, well reasoned article on the problem that people who exist just to make other?s lives miserable pose to any online environment. It discusses the common methods for dealing with them, and looks into why many of these are flawed, and what you can do to improve them.

Mice and keyboards, two great tastes...
A good article that puts to words in simple language that which we all know: Virtual environments for the masses are only creeping along because of the interface problem. For most users, a mouse and a keyboard is all they have for input, and true interaction requires just so much more.

Why writing in games matters: Part I?advancing the art of storytelling
"The problem with writing in games is that we point out when it's terrible, but we don't praise it enough when it's good."

Large Image Display: Program: Welcome back to the Real?
The closing scene from the Animatrix short, Program, has two very important and pertinent lessons to teach. One concerns the problem with grasping the emotions, the other a reminder about interfaces.

The Spinal Cord
A basic overview of the spinal cord, and the reasons why it is such a problem to repair, or interface a prosthetic onto.

The Problem of the Soul: Two Visions of Mind and How to Reconcile Them

A reconciliation of two conflicting visions of what a person is--one embedded in our humanistic traditions, the other advanced by mind science--from one of the most influential philosophers of our time.

Judging Emotions with Age
Emotional states can be a difficult thing to judge. We already know that different cultures see facial expressions differently, but what about different ages? It is both a social problem and a health one, with humanoid robots and AI controlled avatars taking over an increasing number of home care applications.
