摘要：A data input system is described comprising a surface pen and a plurality oftransducers The surface has a structure such that when the pen is moved across thestructure vibration is generated. This is detected by the transducers and the position of

the pen on the surface is calculated. In the preferred embodiment of the invention thestructure of the surface varies across the surface This means vibration signal waveformsmay be associated with specific regions of the surface making identification of the penlocation easier.
