## Abstract

An improved children's computer keyboard includes enlarged keys that are color-coded according to function group. The enlarged keys provide wider top surface and area between keys, which provides each key with a larger error-free zone than a conventional computer keyboard, thus making the present invention more tolerant for human error. Characters on the keys of the improved children's computer keyboard are also enlarged for improved visibility. The keys are arranged in a conventional QWERTY layout.

## Claims

a numerical key group, an alphabetical key group, a programmable function key group, a punctuation and text-editing key group, and a cursor control key group, each of said groups of keys being a different color;
each of said key groups consisting of square or rectangular keys with enlarged top surface and base dimension relative to those of conventional keyboards wherein
a.) said top surface of rich said key being 3/4" from end to end along a line that is parallel to at least one top surface edge; and
b.) said base dimension of each said key being 1" from end to end along a line that is parallel to at least one base dimension edge.

### Claim 2 (depends on 1)

The computer keyboard of claim 1, wherein the alphabetic key group is arranged in a QWERTY layout.
