Abstract
A computer keyboard is provided having keys that vary in size based on the keys' frequency of use. The keyboard may, for example, be modeled after the standard QWERTY keyboard, but modified such that keys for letters of the most-commonly used letters in the alphabet (such as ETOANIRSH) are larger, and keys corresponding to seldom-used letters (such as YWGBVKXJQZ) are smaller. Such a keyboard may advantageously increase overall ease-of-use and accuracy compared to a keyboard of similar size with constant-sized keys.
