Abstract

A thumb operated keyboard device provides a keyboard which can be held such that a user's thumbs are free and positioned to manipulate keys on the keyboard. The device includes a rectangular panel. Each of a plurality of keys is positioned on a front face of the panel. The panel is configured for operationally coupling to a computer such that the computer receives input from manipulation of the keys on the panel. Each of a plurality of pads is coupled to a peripheral edge of the panel. Each of the pads is positioned to extend around an associated corner of the panel to abut a user's fingers such that the panel is holdable in a stable position with the user's thumbs positioned proximate the front face to manipulate the keys. Alternatively, projections extend from a back face of the panel to facilitate holding the panel.
