Abstract: A pair of left and right ergonomic keypads may be separately positioned on a desktop or in the armrests of a chair to permit the user to operate the keypads while assuming more comfortable and natural hand and wrist positions than required when using prior art slab keyboards. The separate keypads may be hingedly, interlockingly joined to function as a compact unitary keyboard for desktop use. When so joined for desktop use, the keypads may be rotated about a point of attachment to any desired position from an open position to a closed position. When in the closed position, the keypads form a compact, diamond-shaped unitary keyboard providing improved portability. Whether employed in a desktop or an armrest application, the keypads may be adjusted to any angle that the user finds most comfortable and convenient for operation.
