Abstract
A data input system is described comprising a surfacepenand a plurality of transducersThe surface has a structuresuch that when the penis moved across the structurevibration is generated. This is detected by the transducers and the position of the penon the surfaceis calculated. In the preferred embodiment of the invention the structure of the surfacevaries across the surfaceThis means vibration signal waveforms may be associated with specific regions of the surface making identification of the pen location easier.
