We propose the use of a touch-sensitive screen as a tool to facilitate acquisition of data both in point counting and morphometric planimetry. It obviates the use of a 'correspondence image' required with many planimetric devices in which the means for data acquisition and display are separate. The touch-sensitive screen offers operational advantages over the light pen. The characteristics of this new graphical input device, its assembly and basic operational considerations are introduced and discussed.
