Abstract:
1. A capture device for capturing and processing hand annotation data that comprises at least three functional layers including: (a) a bottom rigid layer having a surface that provides a mechanical support for writing; (b) a top flexible touch sensitive passive LCD display layer including particles which change light properties in response to pressure, to produce an apparent ink display; (c) a middle pressure sensor layer for measuring touch pressure electrically independently from the top flexible touch sensitive passive LCD (d) a processing circuit directly coupled to the middle pressure sensor and configured order to create a pressure array or map of a capture active area indicating location and amount of pressure and to send and process the pressure data as inputs to a personal computer separate from the capture device; and (e) an LCD control configured to erase the apparent ink display of the passive LCD display layer in response to an activate signal.
