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.Other References
