Abstract

This article describes a keyboard wherein the row-to-row spacing is reduced by approximately twenty percent over existing keyboard designs. It is traditional to design keyboards so that the successive keys in a row are spaced at 19 mm (3/4") intervals, and so that the successive rows are also spaced at 19 mm intervals. Smaller keyboards have been made with both dimensions reduced and with size and/or spacing reduced for less important keys. While there is a good reason for the key-to-key spacing in a row to be 19 mm, there appears to be no equally good reason for not reducing the row-to-row spacing. The reason for the 19 mm key-to-key spacing in a row is that there are many people whose finger joints are wide enough that they would have trouble typing if the spacing were reduced.
