Abstract
A computer implemented method for computing a plurality of virtual texture waveform definitions, comprising: obtaining first texture data at least partially characterising a texture of an existing writing surface, obtaining second texture data at least partially characterising an intended texture experienced by a user when the haptic writing instrument when writing on the existing writing surface, generating virtual texture data by modifying the first texture data based on at least the second texture data, segmenting the virtual texture data into at least first and second regions representing, respectively, at least a first texture type and a second texture type, generating at least first and second virtual texture waveform definitions corresponding, respectively, to the first and second texture types, and outputting at least the first and second virtual texture waveform definitions.
