<p>A fully functional one-hand keyboard (200) for entering data into a computer device, the one-hand keyboard (200) including a housing with a plurality of actuable keys. The actuable keys including primary (202-230) and secondary keys (204, 242, 246, 248 and 250), wherein the primary (202-230) and secondary keys (204, 242, 246, 248 and 250) are capable of generating inputs of a standard keyboard for transmission to a general-purpose computer. The horizontal keys spacing (270) of the primary (202-230) and secondary keys (204, 242, 246, 248 and 250) lies within the range of 87%-106% of the range of 18mm-21mm, centerline-to-centerline, the vertical key spacing (260) of primary (202-230) and second keys (204, 242, 246, 248 and 250) within range of 87%-106% of 18mm-21mm, centerline-to-centerline, resulting in a keyboard footprint that is not greater than 80mm x 53.5mm.</p> |
