After a sufficient number of attempts the pattern of weights stabilises and a particular sort of input (say an image of the digit 2, translated into electrons by a digital camera) reliably produces a particular sort of output.
All told, production-distorting aid (the sort keyed to crop and agricultural input prices) fell from about two-thirds of the total to less than one-third.
With the delay between touch inputand screen response slashed by orders of magnitude, a device that sports the sort of super-low-latency Dietz envisions has the potential to feel far more (for lack of a better term) natural than its brethren.
