Precision experiments of hand tracking task revealed new characteristic features of human percepto-motor control. It was experimentally verified that not only the hand motion statisticallyprecedes the target motion in a steady motion run within a finite frequency range of target motion, but also the amount of precedence coincides with the optimal value for which the transient error of hand motion is minimized when the target motion is unexpectedly changed. The results suggested that the human percepto-motor control system, whose characteristic time is slow and comparable with the that of target motion, has learned in the history of natural selection a proactive control which minimizes dynamic error by a phase-lead operation. It was also shown that a model feed-forward control systemwith delay reproduces the main features of the experimental results.

Building computers with molecular electronic components requires architectures that allow for bulk production and that are free from the problems associated with the ever-increasing integration densities of computer chips. One promising computer architecture for such nanocomputers is an Asynchronous Cellular Automaton, which is an array with a huge amount of cells arranged in a regular structure. Each cell has the ability to do an extremely simple operation at any arbitrary time and can only communicate with its direct neighbouring cells. This presentation shows ways to compute efficiently by Asynchronous Cellular Automata based computers.
