ABSTRACT:
There is provided an adjustable, curved keyboard having arcuately arranged keys to complement naturally to a user's wrists, hands and fingers. The keyboard is supported by a bracket, which extends from underneath the desktop of a desk, for pivotal, elevational and horizontal adjustment of the keyboard's position relative to the user. The keyboard comprises an elongated base and alphanumeric keys positioned at an upper surface of the base. The base has a longitudinal axis disposed below the upper surface of the elongated base, and the upper surface is curved about the longitudinal axis. Also, the alphanumeric keys are arranged about the longitudinal axis of the base to form an arcuate typing surface that provides a comfortable typing surface for the user and reduces the risks of repetitive stress injury.
