aphie, re: the elect. chair. The air force is currently experimenting with a mesh inner flight suit that has sensors in it that generate a signal that can be felt by the pilot. The suit is connected to the F 16's heads up screen computer , the screen that appears in the windshield portion of the canopy directly in front of the pilot. This screen shows him everything going on around him, other planes that have a lock on him, incoming missles etc. All this info, "situational awareness", leads to "visual overload" that the pilot must percieve , process and react to in order to survive. The suit generates signals thru the sensors that are placed in different areas of the body . A buzz in the right upper back may be "hard right climb now". This happens faster than the pilot can process the info and so far has good results.
My thought is that this concept can easily be applied to trading algorythms. If I take a couple pair of my wifes pantyhose, cut a hole in one and slip it over my head you could write a program for the algorythms I use. We could make it wireless so the wearer can answer the door . I know Faster will want one.
