SYSTEM AND METHOD FOR CAPTURING HAND ANNOTATIONS |
摘要 |
A capture device for remote, virtual on screen data input by hand annotation comprises at least three functional layers including a bottom rigid layer, a middle pressure sensor layer and a top flexible layer. The bottom rigid layer has a surface that provides a mechanical support for writing. The middle pressure sensor layer is adapted to measuring a pressure array or map on the capture active area and to send data representing the measured pressure to a personal computer. The top flexible touch-sensitive passive LCD display layer includes an LCD surface by which whatever is written down on the LCD is impressed graphically due to its liquid crystal physical properties wherein applied pressure changes the crystal particles orientation and light properties, such that when a stylus presses against a writing surface thereof, it leaves a visible trace allowing the user to produce a drawing though no real ink has flown.
