Abstract
Keys are arranged on a keyboard as learned during a training stage. During training, a training corpus of input symbol sequence is provided. Each unique symbol in the corpus has an associated key on the keyboard. A cost function that measures a cost of inputting the symbols of the training corpus is globally minimized. Then, the keys are arranged on the keyboard according to the globally minimized cost function. To reduced the distance a pointer must move, the keys can also be arranged in a hexagonal pattern.
