INTRODUCTION

 Fax machines became popular around the
  world in the 1980s.

 In order to reduce paper consumption we
  use paperless fax machine.

 In this paperless fax machine single-touch
  panel is used as input and output device.
 Transmitted and received fax documents are
  stored in memory.

 A pressure sensitive stylus is used to write
  on the touch panel.

 Handwriting reconstruction algorithm is
  used.
HARDWARE CONFIGURATION
 The modem module for sending and receiving
  faxes.

 The touch panel displays the fax documents and
  accepts the handwriting signatures.

 The tip of the pressure sensitive stylus is
  connected to a pressure sensor through a spring
  coil.

 During a signing act, the pressure at the tip is
  measured, digitalized by an ADC, and finally sent
  to MCU for subsequent processing.
OPERATING PROCEDURES

 The touch panel fax machine can operate in one
  of the three modes:


     1. Fax receiving mode
     2. Browsing and handwriting mode
     3. Fax transmitting mode
HANDWRITING
            RECONSTRUCTION
 The handwriting reconstruction algorithm, turn an
  user’s signing act into a digital signature as close
  to the original as possible.

 During the signing act, the data from the pressure
  sensitive stylus and the touch panel are sampled
  by using timer interrupts in MCU.
 The sampled analog
  values are then converted
  into digital values by
  ADCs and buffered in two
  FIFO queues in order as
  shown in figure.
 Some issues that are considered in data
  collection and processing.

         1. Resolution of touch panel
         2. Signal synchronization
         3. Pressure and Strokes
         4. Handwriting Reconstruction
Resolution of touch panels:
  A single-touch panel is composed of two major parts,
   an LCD screen for displaying and a thin touch layer
   for inputs.

  The resolution of an LCD screen is specified explicitly
   by enumerating the number of pixels both in width
   and height.

  The resolution of the touch panel is determined by
   the number of bits used in the ADCs adopted.
Signal synchronization:
  Single-touch panels can response exact one location
   that is being touched at a time.

  Timer interrupt intervals are made set to be constant.

  According to changes in the pressure data measured,
   handwriting reconstruction algorithm can generate the
   strokes with different thickness.
Pressure and Strokes:
 A simple two-step calibration
  procedure for the stylus is
  performed before writing.

 First, press the pen tip all the way
  down and record the pressure
  reading as PF .

 Next, let the tip off the touch panel
  and record the pressure again as
  PE.

 For any pressure P, the pressure
  ratio(PR) is calculated as
       PR=(P-PE)/(PF-PE)
Handwriting reconstruction:


 There are two types of methods to generate
  thickness of the stroke

        1. line extension
        2. circular extension
Circular extension is used in handwriting
reconstruction.
CONCLUSION

 By using handwriting reconstruction algorithm the
  signature can be exactly reproduced.
 Consumption of paper can be reduced.
